The following is an excerpt from chapter three of my upcoming IB Economics Textbook published by Pearson Baccalaureate

Understanding price elasticity of supply, which measures the responsiveness of producers to changes in the price of different goods, allows firm managers and government policymakers to better evaluate the effects of their output decisions and economic policies.

Excises taxes and PES: A tax on a particular good, known as an excise tax, will be paid by both the producers and the consumers of that good. When a government taxes a good for which supply is highly elastic, it is the consumer who ends up bearing the greatest burden of the tax, as producers are forced to pass the tax onto buyers in the form of a higher sales price. If the producer of a highly elastic good bears the the tax burden itself, it may be forced to reduce output to such a degree that production of the good becomes no longer economically viable. A tax on a good for which supply is highly inelastic will be born primarily by the producer of the good. The price paid by consumers will only increase slightly while the after-tax amount received by the producer will decrease significantly, but in the case of inelastic supply this will have a relatively small impact on output. A graphical representation of the effects of taxes on different goods will be introduced in chapter 4.

Price controls and PES: A common policy in rich countries aimed at assisting farmers is the use of minimum prices for agricultural commodities. The European Union’s Common Agricultural Policy (CAP) involves a complex system of subsidies, import and export controls and price controls, the objective of which is to ensure a fair standard of living for Europe’s agricultural community. The use of minimum prices in agricultural markets can have the unintended consequence of creating substantial surpluses of unsold output. Take the example of butter in the EU. The following excerpt was taken from the January 22, 2009 issue of the New York Times:

“Two years after it was supposed to have gone away for good, Europe’s ‘butter mountain’ is back… Faced with a drastic drop in the [demand for] dairy goods, the European Union will buy 30,000 tons of unsold butter. Surpluses… have returned because of the sharp drop in the [demand for]… butter and milk resulting partly from the global slowdown.

In response, the union’s executive body, the European Commission, said it would buy 30,000 tons of butter at a price of 2,299 euros a ton… Michael Mann, spokesman for the European Commission, said that the move was temporary but that if necessary, the European Union would buy more than those quantities of butter — though not at the same price.”

The situation in the European Union butter market can be attributed to an underestimate by policy makers of the responsiveness of butter producers to the price controls established under the CAP. A minimum price scheme of any sort, if effective, will result in surplus output of the good in question, but the 30,000 tons of unsold butter in Europe appears to exceed the expected surplus considerably. The graph below illustrates why:

A price floor (Pf) is set above the equilibrium price of butter established by the free market. Butter producers in Europe are guaranteed a price of Pf, and any surplus not sold at this price will be bought by the European Commission (EC). Assuming a relatively inelastic supply, which corresponds with the short-run period (Ssr), the increase in butter production is relatively small (Qsr), resulting in a relatively small surplus (Qsr – Qd). In the short-run, the amount of surplus butter the EU governments needed to purchase was minimal. But as we learned earlier in this chapter, as producers of goods have time to adjust to the higher price, which in the case of the CAP is a price guaranteed by the EC, they become more responsive to the higher price and are able to increase their output by much more than in the short-run. Slr represents the supply of butter in Europe after years of the minimum price scheme. As demand has fallen due to the global economic slowdown, butter producers have continued to produce at a level corresponding with the price floor (Pf), leading to ever growing butter stocks and the need for the EC to spend, in this case, 69 million euros on surplus butter.

Understanding the behavior of producers in response to changes in prices, whether due to excise taxes or price controls, better allows both firm managers and government policy makers to respond appropriately to the conditions experienced by producers and consumer in the market place and avoid inefficiencies resulting from various economic policies.

Discussion questions:

1. Explain why the price elasticities of both demand and supply of primary commodities tend to be relatively low in the short run and higher in the long-run.
2. Explain the factors which influence price elasticity of supply. Illustrate your answer with reference to the market for a commodity or raw material.
3. Discuss the importance of price elasticity of supply and price elasticity of demand for producers of primary commodities in less developed countries.

With more than four million Spanish people out of work this week, the eighth largest economy in the world finds itself once more in a perilous position. In the last twelve months the number of unemployed people in Spain has doubled. Spain now has as many unemployed people as France and Italy combined, and the unemployment rate is nearing the historic highs of 1993.

The type of unemployment in an economy can be classified in different ways. The main types are cyclical or demand deficient unemployment but other forms exist such as real-wage unemployment and equilibrium unemployment. Some economists also refer to unemployed people as structural, frictional, seasonally or cyclically unemployed.

From the graph below we can see that unemployment in Spain has been high for at least the last 20 years, compared to other countries within the European Union.

Source: OECD Factbook 2009: Economic, Environmental and Social Statistics

The cause of growing Spanish unemployment in 2008 to 2010 is related to the collapse of the domestic building boom and the wider global recession. In 2006, Spain enjoyed low interest rates and therefore cheap loans, this allowed developers to build new apartment blocks, houses and commercial buildings with a relatively low cost of borrowing. Spanish people could afford mortgages at low interest rates and therefore purchased houses contributing to the building boom. However, when the flow of “cheap money” ran out in mid 2008 the building stopped and the flow on effects of spending dried up. Falling tourism receipts and less foreign investment have also exacerbated the issue leading to unemployment doubling between 2008 – 2010.

We can classify the form of unemployment, illustrated in the Spanish example as demand-deficient unemployment. It is related to a downturn in the economic cycle. This concept is explained below.

Effects and Solutions

The social and economic impacts of 20.7% unemployment are obvious, but the solutions are less so. Climbing unemployment creates two evils; falling tax revenue as workers no longer earn wages and the increased burden of paying benefits to the four million unemployed citizens. In addition, a series of social problems are often intertwined with high unemployment, these include depression; lose of skills, poverty and higher crime rates. Spain therefore has a few problems to solve this summer. Whilst Spanish people may enjoy a summer by the beach, and a glass of sangria, the government will be hitting the books to find a solution to the problem. Here are a few suggests to get the politicians thinking.

• Use fiscal stimulus to boost consumer and government spending, thereby increasing the demand for jobs. Spain could plan for a budget deficit (expansionary fiscal policy) and fund spending increases though increased government borrowing. Spain’s current level of public debt is 67% of GDP, which is well below stricken Greece at 124%. However, Spain now has to borrow money from international bond markets, which are skeptical about Spain’s ability to pay back this debt. This is despite assurances and favourable rates offered from the European Union this week. Increasing government debt in a period of European financial crisis is a risky option.

• Use loose monetary policy (lowering central bank interest rates) to encourage Spanish people to increase their consumer spending through increased borrowing. If you understand the complexities of the European Union, you understand that all 21-member countries use the same currency and follow the lead of one central bank. Despite one country wishing to lower interest rates, other countries may think differently. Europe can be compared to a train rolling along on a set of rails, with 21 separate carriages. Each European country must follow behind the big engine, there is no room to deviate from the central banks interest rates and all of the countries must move together. Many people have wondered how long the European train would run, before one of the carriages derailed.

• Force Spanish firms to employ more people. Firms have no requirement to hire more people. They may choose to employ more people but will logically offer everyone lower wages to maintain profitability.

• Use supply side policies to bring greater efficiencies to firms though increased on the job training and worker education. This is a long-term solution, which will require large structural adjustments, how Spain produces goods and services and exactly what is does produce. A startling statistic is that the average Spanish university graduate will find their first job at the age of 27, long after they have graduated.

Discussion Questions:

1. How do economists measure unemployment?
2. Explain how expansionary fiscal policy could reduce the rate of unemployment?
3. What does the concept of the natural rate of unemployment represent?
4. Evaluate the effectiveness and suitability of supply side policies to reduce unemployment in Spain

Introduction: The following is a selection of a chapter from my new Economics textbook project, the Pearson Baccalaureate Economics text, which will be available to IB Economics teacher for the 2011-2013 school year.

It should be noted that the original Phillips Curve theory did not distinguish between the short-run and the long-run. In fact, the original Phillips Curve itself was a long-run model demonstrating a trade-off between unemployment and changes in the wage rate over a span of 52 years in the United Kingdom.

Up until the early 1970s, the Phillips Curve was treated as a generally accurate demonstration of the relationship between two important macroeconomic indicators. Throughout the 60′s data for the United States showed in most cases that increases in unemployment corresponded with lower inflation rates, and vis versa.

1. Why does Hayek's "classical" aggregate supply curve always lead to an equilibrium level of national output equal to the full-employment level of
   

    real GDP?

2. The vertical AS curve above is sometimes referred to as the "flexible-wage and flexible-price" model of the macroeconomy. Why must wages and prices be perfectly flexible for this model to be an accurate representation of a nation's economy.
3. Hayek was an advocate for free markets, he felt that government intervention in a nation's economy would only interfere and disrupt the efficient allocation of resources. How does the model above reflect his belief that governments cannot improve a nation's level of output beyond what the free market is able to achieve?
4. Do you believe that the classical model of aggregate supply is representative of the real world? Why or why not? What evidence is there from recent history that the model is or is not accurate?

Figure 2: The Keynesian AD/AS model

1. Based on the model above, which level of aggregate demand corresponds with the macroeconomic goals of "full-employment and stable 
   

   prices"? 

2. Changes in which factors could cause aggregate demand to shift from AD2 to AD3? If AD falls to AD3, what happens to the price level in the economy? What happens to the level of output of goods and services? What happens to employment and unemployment?
3. Sometimes the Keynesian AS model is known as the "sticky-wage and sticky-price model". How does the model reflect the idea that wages are downwardly inflexible, in other words, will not fall even if demand for goods and services fall? For what reasons might wages in an economy be downwardly inflexible (in other words, not fall even as total demand in the economy falls)?
4. How realistic is the Keynsian model of aggregate supply in the real world? 
1. Can you point to any evidence from the last few years that it might be correct (in other words, that a fall in AD will lead to decrease in national output?) Find data on the GDP's of two Western European countries from 2008 and 2009 to support your findings. 
2. Can you point to any evidence from the last few years that the model might be flawed (in other words, that a fall in AD actually does lead to a fall in the price level)? Find data on inflation in the same two Western European countries to examine whether or not wages and prices are completely inflexible downwards as the model suggests.

1. How does the above model represent a compromise between Keynes' and Hayek's view of aggregate supply?
2. Why are there two aggregate supply curves? What is the difference between the two?
3. What happens in the SHORT-RUN when AD falls from AD2 to AD3 to the price level and output? What will happen in the long-run? In macroeconomics, the short-run is known as the "fixed-wage period" and the long-run the "flexible-wage period". The main factor that can shift the SRAS curve is the level of wages in the economy (in other words, a change in wages will shift the SRAS). How does this help explain the adjustment from the short-run equilibrium and the long-run equilibrium following a fall in AD?
4. What happens in the SHORT-RUN when AD increases from AD2 to AD1? What will happen in the long-run? How does the long-run flexibility of wages explain why output always seems to return to its full employment level of output in the long-run?
5. What does the model above indicate about the possible need for government intervention to help an economy achieve its macroeconomic goals of full-employment and price level stability in the short-run? 

The launch of the iPad a few weeks ago, heralded a new period of competition in the market for tablet and slate computers. The three videos below, suggest that although Apple may have seized the lead the in the growing market, many other competing firms will be launching new products to entice customers to part with their money.

From first impressions, the market seems to be oliogopolistic in nature, where a few large firms (Apple, HP, Lenovo/IBM) share a large portion of the total market. At the moment it appears that Apple has the lead, and has created a product with unique selling points such as touch capability and a book reader. You can envisage from the video that HP will closely follow developments and try introduce other selling points eg. USB ports, built-in camera.

Discussion Questions:

1. What are the key difference between an oligopoly and monopolistic market structure?
2. What happens to the profits of the monopolistic firm in the “followers phase” when other firms copy features of the market leader?
3. Explain whether barriers to entry exist in the market for tablet computers?
4. Do you think firms in the tablet market would opt for price competition or product differentiation strategies to gain market share? Explain the advantages of each.

As the Singapore economy rebounded spectacularly this week ,the government moved to limit inflationary pressures. This was after year-on-year economic growth reached 13.1% in the first quarter of 2010.  This strong performance was related to the increased demand for electronic components and growth in the pharmaceutical industry.

The Singapore government operates a managed exchange rate regime. The Singapore dollar is pegged to a trade-weighted index of five currencies. The exact make-up of the index is kept secret, but the rate is allowed to fluctuate within a four percent target range. This ambiguity leads to less speculation by currency traders, and what is known as a basket, band and crawl method of currency management. Overtime, this has allowed the government to steadily appreciate the currency as demand for exports surged. Since 1980’s the value of the Singapore dollar versus the US Dollar has appreciated by nearly 80%.

This exchange rate mechanism is also how the government controls the rate of inflation in the small city-state. Because Singapore’s net exports make up over 100% of GDP, a subtle appreciation of the exchange rate leads to less imported inflation and less demand for exports. The effect of a 1.3% appreciation of the currency band this week, is expected to reduce inflationary pressure over the next 12 months.

The approach is something that the Chinese government is maybe looking towards. The Yuan is pegged directly to the US Dollar and has been since mid-2007. China has been able to maintain this peg by selling vast amounts of yuan to purchase US Treasury Bonds, and to thereby create large foreign currency reserves. As widely reported, the Chinese government has been under pressure to appreciate the yuan by anything up to 60% compared to the US dollar. How the government achieves this shift is complicated but may lead to a significant loss of export competitiveness and imported inflation.

However as Wei Gu from Reuters reports,

“This (Singapore) approach is not open to China, whose inflationary pressures are home-grown, and whose exchange rate looks more undervalued. Nevertheless, Beijing can learn from Singapore’s model, which offers a better balance between stability and flexibility”

Of course, there are huge differences between a city-state and the world’s third-largest economy. Singapore, whose foreign trade is three times its GDP, has to allow enough freedom in its exchange rate to achieve domestic price stability. China, where foreign trade accounts for 50 percent of GDP, that incentive is much smaller.

Moreover, China could not adopt Singapore’s approach without a one-time appreciation in its currency. Otherwise it would be hard to create a two-way trade: China currently restricts the yuan’s movement against the dollar to just 0.5 percent every day. Nevertheless, as China considers making its exchange rate more flexible without abandoning stability, the Singaporean model is worth studying.”

Discussion Questions:

1. What are the advantages and disadvantages of a floating exchange rate?
2. What are the advantages and disadvantages of a fixed exchange rate?
3. What is the common tool used by many governments to control inflation. Why can’t all countries use the Singapore approach?
4. Can a country use both Monetary Policy and a managed exchange rate to control inflation? Do trade-offs exist?
5. Evaluate the effects on the Chinese economy of an appreciation of the yuan.

When teaching international trade to high school economics students, one of the challenges is understanding the pros and cons of trade surpluses and deficits. A country’s balance of trade refers to the net flow of revenues and expenditures goods and services between the country and its trading partners. In technical terms, this is known as the current account on a nation’s balance of payments. A country that spends more on imports than it earns from the sale of exports has a current account deficit. A nation that earns more from the sale of its goods and services to the rest of the world than it spends on imports has a current account surplus.

A common impressions among students is that a trade surplus is good and a trade deficit is bad. One challenge I face in teaching this topic is separating economic terms such as “suplus” and “deficit” from non-economic, normative concepts such as “good” and “bad”. In fact, a trade surplus is not always a good thing. To illustrate, I will look at the current account balances between China and the United States. In 2007, the US ran a trade deficit with China of $258 billion. While the US imported $321 billion of Chinese goods and services, it only earned $63 billion from the sale of exports to China. To most students, it would appear that China is “winning” in the game of trade, since it has such an enormous trade surplus with the United States. This, however, is not necessarily the case.

One way of looking at trade balances is that a nation with a substantial current account surplus is actually consuming less of its own output due to the high demand from abroad. As mentioned above, in 2007 Americans spent $321 billion on Chinese goods and services. China only produced $3.2 trillion of goods and services that year, meaning Americans actually consumed over 10% of the stuff produced in China! This represents Chinese output that is NOT being consumed by the Chinese. Additionally, since China imported far less from abroad than it sold, Chinese output being consumed abroad is far from made up for by Chinese consumption of foreign output. While this may sound like a good deal from the perspective of producers, who have a larger market due to trade, from the perspective of Chinese households it means they are consuming less than they are producing as a nation!

One of the goals of macroeconomics is to increase the standards of living of the nation’s people through an increase in the consumption of goods and services. In this regard trade deficit countries are actually better off than trade surplus countries, since they are actually consuming MORE than they are producing as a nation! A trade deficit country gets more than it gives, in a way, which sounds pretty good when if you consider total consumption to be an end in itself. A trade surplus country, on hte other hand, gives the rest of the world more than it gets in return (in terms of goods and services, that is).

Another consequence of running a large trade surplus is the build up of foreign exchange reserves. China, for instance, held over $1.3 trillion USD in its central bank in 2007, representing an enormous level of savings for the Chinese people, since these are dollars earned by the people of China (from their export sales to America), but not spent. These reserves represent a form of forced savings on the people of the nation.

The average Chinese consumer is also made worse off because the governments’ US dollar reserves are held intentionally to keep the value of the dollar high, thereby keeping the price of American and other nation’s imports prohibitively high for Chinese consumers. In this regard, China’s 50% national savings rate is a form of financial tyranny by the government perpetrated against the Chinese people, who, as consumers, would be much better off if the RMB were allowed to appreciate and imported goods and services could be more easily and affordably attained by Chinese households. Employment in the export sector might suffer but falls in exports would likely be made up for with gains in domestic consumption, meaning the overall effect on employment is likely to be mild upon a reductions in China’s trade surplus.

Furthermore, in order to maintain China’s trade surplus the Chinese government must keep the RMB weak. As already mentioned, one way it does this is by holding its US dollar reserves to keep the supply of dollars on foreign exchange markets low and its value high. Another way the Chinese central bank manipulates its currency is by constantly changing the level of interest rates to limit or encourage foreign capital flows into or out of the country, since such flows affect the Chinese currency’s value. If the Chinese central bank and government were to adopt a flexible exchange rate policy, which would help reduce the country’s trade surplus with the United States, this would allow the central bank to use monetary policy in the way it is meant to be used: to stimulate or contract the level of domestic consumption and investment. This week US Fed chairman Ben Bernanke spoke to the US Senate about China’s exchange rate controls, and made a similar point:

“Most economists agree the Chinese currency is undervalued and has been used to promote a more export-oriented economy. I think it would be good for the Chinese to allow more flexibility in their exchange rate.”

Letting its currency, the renminbi, appreciate would give China’s central bank more flexibility in monetary policy and help stimulate domestic demand and consumption, Mr. Bernanke said

China’s trade surplus does not necessarily benefit the country as a whole. Surpluses do keep export sector employment high, but result in a lower overall level of consumption among Chinese households and impose a higher than necessary level of savings on the nation. More balanced trade would increase the level of imported goods and services in China, increase real incomes as the value of the nation’s currency rises, and also allow for more inflows of foreign capital from abroad, further stimulating growth in China’s domestic economy.

Directions: Macroeconomics is an area of study with precise goals attached to it. Macroeconomists generally agree that there are three primary goals towards which policies should be used to try and achieve:

• Full employment of the nation’s resources, including labor, land and capital.
• Price level stability, meaning a low (generally between 2% and 4%) inflation rates
• Economic growth, meaning a year on year increase in the nation’s output of goods and services and the average income of the nation’s people.

Understanding the indicators used in macroeconomics to measure the success in these three areas is important. In the activity that follows, you will research, define, and explain the various types of inflation, unemployment and economic growth. You will also research and record examples of these indicators from several countries. Finally, you will investigate your OWN country, and determine what precisely makes up the total amount of economic activity in your country.

Singapore is an economy which is operating at a level which is very close to its full potential. The island has no natural resources, very little spare land and a small but educated workforce. The recent global financial crisis, highlighted Singapore’s vulnerability to changes in the global economy. Singapore is very export dependent country with a large positive trade balance.

The latest government budget was announced here last week and the focus has shifted towards improving productivity in the economy to make it more resilient to these external shocks in the future. The shift has been from Demand Side Policies a year ago, at the depths of the recession, to Supply Side policies in the recovery phase.

Singapore has always been considered one of the original Four Asian Tigers. The four tigers (Hong Kong, South Korea, Taiwan and Singapore) were economies, which shared the free market policies and outward looking, export orientated philosophies. All four countries were newly industrialized, and throughout the period between the 1960’s and 1990’s  they all experienced exceptionally high rates of economic growth. More recently other countries tried to follow this model on a road to development.

S’pore unveils Budget aimed at helping country become advanced economy: By Imelda Saad, Channel NewsAsia | Posted: 22 February 2010 link

SINGAPORE: Finance Minister Tharman Shanmugaratnam has unveiled a Budget aimed at helping Singapore become an advanced economy.

A key theme of the Budget: raising the quality of jobs, skills and the workforce so that workers can continue to earn higher incomes, and the economy, grow.

Singapore emerged from the global financial crisis better than expected, with an overall budget deficit of S$2.9 billion for FY 2009 – much lower than the original S$8.7 billion shortfall projected a year ago.  This year, it is expecting a deficit of S$3 billion, as it spends on areas to boost productivity. The government’s key focus is to raise productivity by 2 to 3 per cent a year over the next decade. This will allow Singapore to maintain a healthy rate of economic growth of 3 to 5 per cent a year, even with a slower growth in the labour force.

The government has therefore managed its spending and revenues in the previous 12 months so is now in a position to spend money to boost the future prospects of the economy. This is unlike some other nations such as the United Kingdom which is searching to cut spending to reduce future budget deficits.

The finance minister said the Budget 2010 set out ways to help Singapore succeed with new growth strategies. Hence the plans seemed to focus more on the long-term growth and health of the economy, and not just the short-term position. The government has set aside S$5.5 billion over the next five years to help enterprises and workers raise productivity.

Mr Tharman said: “Raising skills and productivity is the only viable way we can achieve higher wages and is the best way to help citizens with low incomes. If we achieve this goal, we can raise real incomes by one-third in 10 years.”

The Finance Minster is focusing on long-term growth and the health of the economy. This suggests that Singapore is using supply side policies to increase the potential capacity of the economy and shift the Long Run Aggregate Supply curves towards the right. From a Keynesian perspective, supply side policies are effective when the economy is approaching it’s full potential. The policies are considered ineffective when the economy is a recession with depressed aggregate demand. This idea is illustrated below. (note: the same policies can also be illustrated slightly differently, using a neoclassical perspective of LRAS)

The minister signalled that some painful decisions may have to be taken. Less-efficient industries may have to exit Singapore, as the economy continues to restructure. Mr Tharman said the government must rely on the market to achieve this restructuring. Industries and companies will be given help to upgrade through tax benefits and grants to help to innovate and raise productivity, and invest in R&D and automation.

More will be pumped into raising the skills and tapping the potential of every worker. But this will have to be offset by reducing Singapore’s dependence on cheap foreign labour. To encourage companies to rely less on foreign workers, the government is imposing higher levies on foreign workers in phases over the next three years.

The government will pump in S$2.5 billion in over 5 years to enhance Continuing Education and Training.

It will also set up a high-level National Productivity and Continuing Education Council – to be headed by Deputy Prime Minister Teo Chee Hean – to develop a comprehensive system for lifelong learning. In addition, there will be help for older and low-wage workers in a new Workfare Training Scheme. The scheme is aimed at incentivising employers to send older workers for training by providing companies with up to 95 per cent funding for absentee payroll and course fee outlays.

For companies, there will be a Productivity and Innovation Credit so they can get tax deductions for investments in R&D and automation. There are also a slew of measures to help grow more globally competitive Singapore companies. These include tax deductions for angel investors, growth capital for SMEs and incentives to expand sectors with high growth potential.

The government also wants to ensure that no one is left out as it pushes for more inclusive growth, by taking care of the lower and middle income. For example, property tax will be tweaked to be more reflective of the annual values of homes.

Mr Tharman said: “Taking all our measures together, we will be spending S$1.4 billion this year in direct transfers for households. While most Singaporeans will receive some benefits, more will go to those with lower and middle incomes.”

In wrapping up the nearly two-hour speech, Mr Tharman said while the government will commit substantial resources to support the national effort of restructuring the economy and improving the quality of jobs, the success of this will depend very much on the ingenuity and drive of Singaporeans and companies here.

Discussion Questions:

1. Explain why in Singapore demand side policies were favoured during the recession, but now Supply Side policies are being introduced.
2. Explain how one of the suggested policies will affect the labour market and therefore the level of aggregate supply in the economy.
3. What does the finance minister mean by the phrase “no one is left out as we push for inclusive growth” and how does the government support inclusive growth?
4. Evaluate the short run and long run effectiveness of supply side policies to increase the level of Real GDP in Singapore.

John Maynard Keynes was an economist whose opinions have shaped government policies throughout the 20^th century. Joseph Sternberg of the Wall Street Journal explained an interesting link this week, between Keynesian policies and the fate of bankrupted Japan Airlines.

Keynesian policies suggest that during a period of depressed economic growth, a chronic lack of the demand is a core problem that couldn’t be solved with supply side policies. Instead he advocated for demand stimulus packages including infrastructure developments.

The Japanese economy has experienced a turbulent past. Throughout the 1960’s, 70’s and 80’s the level for GDP grew at impressive rates, but growth began to slow in the 1990’s due to the effects of an asset bubble. An asset bubble was caused by an abundance of cheap credit caused by exceptionally low interest rates. This lead to the prices of shares, houses and land rising very quickly as buyers speculated and outbid each other. The government responded by sharply raising interest rates in 1989, which crushed the bubble and stalled the economy.  Depressed wealth caused spending to stall, and the Japanese thrift and savings culture to return.

In the 1990’s the government attempted to stimulate the economy but this was largely unsuccessful. The result was low real growth (compared to the past), zero percent interest rates set by the Central Bank and a deflationary spiral. Politicians used a variety of policies, including Keynesian ideas to boost aggregate demand.

During the economic boom, the development of the aviation industry was an important pillar of the countries infrastructure development as Joseph Sternberg of the Wall Street Journal explains.

Starting in the 1960s, successive governments concocted aviation plans focused on building new airports. Perhaps this was justifiable back then, when Japan was an Asian tiger economy with a growing population. But in 1964, even before the bulk of the airport construction, the bullet train appeared. At that point, and especially as the shinkasen high-speed-rail network developed, it might have been prudent to ask whether air would invariably be the most efficient way to connect domestic destinations.

Unfortunately, by then the airport boom had taken on a life of its own. During the lost decade of the 1990s, airport construction popped up in many stimulus plans. National and local politicians, not to mention the politically powerful construction lobby, wanted to put an airport in every prefecture. And ordinary airports wouldn’t do. Because Japan’s relatively small flat surface area is in such high demand, one airport after another was built on reclaimed land in the middle of the ocean at enormous expense. Despite periodic public fulminations about out-of-control costs, in practice “expensive” seemed to be viewed as a net positive.

Boosters touted airports as creators of short-term construction jobs and longer-term boons to their areas. This airport binge has continued right up to today. Japan’s 98th airport opened last year: Shizuoka-Mt. Fuji, roughly 50 miles from the famous mountain. California, with a larger land area, has around one-third as many airports in regular commercial service, with another 35 or so “reliever airports” to handle business jets and general aviation.

The author reflects on the cost of the Keynesian stimulus. Whilst in the short term, development of the airport network provided jobs and helped the construction industry; in the long term the projects have created an inefficient and expensive transport network. Japan Airlines has been forced to offer flights from each of these 98 regional airports, often paying high landing charges, and operating flights at below capacity. Overtime this pressure may have caused Japan Airlines to slide into bankruptcy.  Perhaps this is a unique one off case, but the author predicts some interesting links to current developments in China.

Lest anyone think this is a uniquely Japanese problem, consider all the other places in the world currently undergoing their own Keynesian infrastructure booms—and especially China. For instance, a new high-speed rail line is due to connect Beijing to a station an inconvenient 45 minutes from the downtown commercial center of Guangzhou in southern China. The train will take somewhat less than eight hours to connect cities reachable in under three by air. Will enough passengers ever make that trek for the train to operate in the black?

Discussion Questions:

1. Why does John Maynard Keynes suggest that demand stimulus is an appropriate response, for a country stuck in a deep recession, with depressed demand?
2. If central bank interest rates are very close to zero, what other policies could the government use to stimulate growth?
3. How could supply side policies actually make the recession worse in Japan?
4. Outline the advantages and disadvantages of demand-side policies used in Japan.

One feature of Economics in Plain English several students and teachers have found helpful over the years is the Econ Help Desk, where readers can get questions about basic economic concepts answered personally by me.

Recently I received the following email from an AP Macroeconomics teacher in the United States:

I have a question about graphs that illustrate how trade preferences (specifically Supply and Demand shifts), affect P, Q and Pe on Supply-Demand GRAPHS of Currency Exchange.

In teaching my AP Macro students about this concept, I have reached a gap in our full understanding how to graph the Supply and Demand of Yen, or Euro (Price in USD).

For example, if the Price levels rise in the U.S., relative to Japan’s, and consequently, the U.S. demands more Japanese cars and stereos, the only label that we ever see for the x-axis is “Q” or Quantity, or Qe, a vertical line that represents the starting “market clearing price”, of .01USD=1Y. When DEMAND or SUPPLY shifts, the only change that I ever see labeled on the graphs is the Y-Price in USD of Yen, but descriptions simply talk about the Y=1.

When Demand or Supply shifts (in response to increased demand for Yen), and there is a new higher or lower USD Price for Yen, respectively, does the vertical line for Q simply shift outward (continuing to represent Y=1) at whatever the new Price Equilibrium becomes (simply meaning just more “1s” of them in circulation (at each new Pe market-clearing point)?

Thanks

Here is my response:

Hello, I will try to address your questions below.

Exchange rates can be determined by several factors, including relative price levels, relative interest rates, tastes and preferences of domestic and international consumers, relative income levels at home and abroad and speculation by currency traders. As you say, an increase in the price level of goods produced in United States (say, Fords), ceteris paribus, should lead to an increase in demand among American consumers for goods produced in Japan (say, Hondas), which now appear relatively cheaper. Demand for Yen increases among American households who wish to buy Japanese goods. The USD price of Yen then rises in the Yen market. Since Japanese holders of Yen now receive more USD for each Yen, they will provide more Yen (this is another way of saying with an increase in demand for Yen, the quantity supplied of Yen increases).

Theory would say that there is no increase in the supply of Yen following an increase in Demand by American consumers, only an increase in quantity supplied. The Yen clearly appreciates, as the USD/Yen exchange rate rises. Now, there is another side to this story. The Yen market refers to the market for Yen in the United States. Yen will appreciate in the United States. Simultaneously, USD will depreciate in Japan, as Americans buy more Japanese goods, they are supplying more USD in the USD market in Japan. Here the “price” or the exchange rate is Yen/USD. The Yen price of a USD will fall as the supply of USD increase as Americans exchange their dollars for Yen to buy the relatively cheap Japanese goods.

The “market-clearing price” in foreign exchange markets is the exchange rate that prevails in a floating exchanged rate system where exchange rates are determined solely by supply and demand by international consumers, investors, government, banks, and firms. Assume the Yen is trading for $0.01. If , following inflation in the United States and the corresponding increase in demand for Yen, the value of the Yen remained at $0.01, then the quantity demanded for Yen would exceed the quantity supplied. There would be shortages of Japanese goods in the United States, as Japanese goods are in greater demand yet their prices have not risen. In order to “clear the market” so to speak, the exchange rate must rise, to say $0.012. Now, a Yen’s worth of goods “costs” Americans 20% more than previous, making them less attractive over time. Likewise, a dollar’s worth of goods “costs” Japanese consumers 20% less, since the dollar is weaker in Japan.

As you can foresee, the floating value of the Yen should lead to relatively balanced trade between Japan and the US. The US current account will initially move towards deficit as inflation makes American goods more expensive, however, as demand for Japanese goods increases, the value of the Yen rises making Japanese goods more expensive, which will eventually reduce their appeal to American consumers who will once again begin consuming more American goods and importing less. Japanese will notice the weaker dollar makes US imports cheaper and begin importing more American products. The US current account should remain  balanced in the long-run in a floating exchange rate system.

I don’t know if you’ve had a look at my study guides on exchange rates and balance of payments, but those may help clarify graphically what I describe above:

• Unit 4: Exchange Rates
• Unit 4: Balance of Payments

I hope this clarifies your understanding of how relative price levels help determine exchange rates!

Jason

It’s that time of the year for IB Economics students all over the world. Time to choose their extended essay topics! The International Baccalaureate (IB) program is a rigorous, two-year diploma program for 11th and 12th graders. In addition two three “higher level” courses and three “standard level” courses chosen from each of the six subject areas (maths, physical sciences, social sciences, fine arts, language A and language B), students must also complete a major research project over the two year program. This “extended essay” is externally assessed and counts towards their points and their final diploma score.

As an IB Economics teacher, it is my duty to assist students who choose to write an economics extended essay. This year I will supervise four Zurich International School students, who will be researching topics ranging from the competitive nature of the local fast food market, to Malaysia’s economic policy and the country’s development, to the health insurance industry in Switzerland and Brazil’s coffee market. Helping students fine tune their research topics and refine their essay is an exciting and rewarding process.

This afternoon I received an email from an IB Economics student in Berlin. Here’s what she had to say:

Dear Mr.Welker :

I’m currently an IB Grade 11 student studying at Berlin International School, and i would like to write my extended essay in Economics. Your blog has provided me with so many ideas now that the problems is now i don’t know what to choose or how to narrow it down . My ideas are mainly focusing on China’s economy, because I’m from Taiwan, I thought it would be an advantage for me, since i can understand information if it was written in Chinese.

I’m thinking of writing about the following topics:

• Limiting factors of China’s economic expansion (inequality, inflation, protectionism from other countries like US, spending and saving habits of the Chinese, export and import) and maybe the possible future of China’s economy, because while some people say it’s going to help lift the global economy out of recession, some say they see an economic crash.( but I’m not sure if as a high school student is able to do that, at the same time I think one of the criterias is to discover something new ? )
• Another thing i also find interesting is about Chinese currency and how it might solve inflation (I came across this from one of your blog posts about China at May 2008) or what policies do governments use to maintain RMB without buying US exports and the possible effects on other countries as a result of weak Chinese currency

I really can’t decide which one to do, therefore i would really appreciate it if you could advice me and give me some feedbacks.

Looking forward to your responses !

I was happy to receive an email from such an enthusiastic young economist. Below is my response and advice to the student:

Hello,

Your ideas are very interesting… it’s impressive as an IB Econ teacher to see a student as thoughtful and reflective on the EE topic as you are. Here are my thoughts on your proposed topics:

I think your first topic would be particularly difficult to research and write a good essay on. In all honesty, not many of the factors that you identify (inequality, inflation, protectionism from other countries like US, spending and saving habits of the Chinese, export and import) have really limited China’s economic growth. China’s growth has been unprecedented in the world in modern history. Inequality could be viewed as a result of the rapid growth the country has experienced; such inequality has been experienced in many countries during their early stages of economic development. Inflation is also a symptom of rapid growth, but in most cases China has keep inflation under control. It has been the lack of protectionism from countries like the US which have led to the massive growth of China’s export industry. If anything, China’s own protectionist policy of managing the value of the RMB at such a low rate has also contributed to its rapid growth.

Even Chinese spending and savings habits have contributed to the growth of the country’s economy. A high savings rate enables the Chinese government to tap the country’s savings to buy US government bonds, which keeps interest rates low in America, the dollar strong, and helps finance the US government’s budget deficits, meaning lower taxes and more disposable income among American consumers who turn around and import hundreds of billions of dollars worth of Chinese goods every year, further fueling growth in China. With a lower savings rate, China would experience fewer net exports. On the other hand, they’d experience more domestic consumption, which is probably what we should expect to see in the future if Beijing begins to loosens its control of the RMB and allows it to strengthen. Chinese will then begin consuming more of their own output and buying more imports from abroad, while net exports decrease in response to the rising prices of Chinese goods in the west. Domestic consumption will begin to replace exports as domestic savings decreases.

I like your second proposal much better. Since you are in Germany, I would consider researching the effects of China’s exchange rate controls on a particular industry in which both German and Chinese firms compete. I had a student in Shanghai who had a similar background to yours; he was of Chinese descent, but born in Germany. He spoke both German and Mandarin. He researched the impact of China’s low cost automobile parts manufacturers on the German auto parts and automobile industries. He did not focus exclusively on the exchange rate, but it was part of his research.

The IB really likes when you research local markets. If you examine the impact of the weak RMB on, say, US net exports, it’s not nearly as impressive as if you focus your investigation on German firms. You may have friends at your school whose parents work for firms who do business with or compete against Chinese firms. Interview them! You could measure historical exchange rate data between the RMB and the Euro, explain the mechanism by which China manages its currency against the US dollar but then explain how that also affects exchange rates with the Euro, then examine the impact on exports and imports from Germany to China and vis versa in response to the fluctuations of the RMB/Euro exchange rate. America is not the only country that wants China to let the RMB float. Europe’s exports are also affected by the weak RMB.

So that’s my suggestion. Take your two homes (well, not really as you’re Taiwanese, but close enough!) and focus on them. Choose one or two industries that exist in Germany AND China, and research the effects of free trade, China’s entry to the WTO, China’s exchange rate policies, and so on, to draw conclusions about how China’s entry to the global economy has affected firms in Germany.

Good luck, I hope this helps! Click on the “China” category on my blog to find all the dozens of articles I’ve written about China over the last three years!

Best,
Mr Welker

Welker’s Wikinomics Blog was created three years ago as a way to communicate economic ideas and theories in a clear and intelligible way for the high school economics student. Over those three years over 500 posts have been published, nearly 10 Economics teacher have contributed as authors and over 250,000 readers have visited (now up to over 600 per day).  But where did the name Welker’s Wikinomics come from, anyway?

When my adventure in Web 2.0 teaching began over three years ago, there was no blog. At first Welker’s Wikinomics was, not surprisingly, a wiki for my AP and IB Economics students in Shanghai to use as a study tool. But then came the blog, and for lack of a better name, it took on the same name as the wiki. Today the Welker’s Wikinomics name is actually shared by not only the wiki and this blog, but also by the Economics Universe, where econ students and teachers can find RSS feeds from hundreds of resources for learning economics, as well as the free lecture notes I publish here and which have been downloaded thousands of times by Econ students around the world.

Last year I began thinking about changing the name of this blog, as I was never quite satisfied having my blog called “Wikinomics”, since so many visitors to my site have always been confused about the difference between the wiki and the blog. So today I am happy to announce a new name for this blog, Economics in Plain English.

I thought of the new name while writing a blog post recently for which I spent a frustrating hour reading an article from the Economist. While struggling through the difficult article I guessed that most people without at least two years of college economics would have had a hard time understanding what the author was trying to say with all his economics jargon. Why, I thought, aren’t more journalists and academics writing about economics in a way that anyone interested in the subject, whether he be a high school student or a retired grandfather, can understand. Why don’t more people write about economics in plain english!?

Well, that’s precisely what I’ve been trying to do here for three years. So I decided it was the right name for this blog.

From now on this blog can be accessed by going to the URL: http://www.economicsinplainenglish.com. The original domain will remain intact, however, since over 500 articles on this blog are still used by myself and other Econ teachers and their hyperlinks must remain active. Welker’s Wikinomics is not disappearing, as my homepage will still be located at http://www.welkerswikinomics.com. Only the blog is getting a new name. The wiki, the universe, and the lecture notes will continue to be part of the Welker’s Wikinomics suite of resources available for econ teachers and students.

As always, if you’re an economics teacher who enjoys what you read here and think you may have something to add, please drop me an email at welkerswikinomics@yahoo.com to receive an author account on this blog. Become a regular contributor and I’ll add your face and bio to the “About the Authors” sidebar! How can you pass that up?

A big thanks to everyone who has visited this blog, read our posts and left a comment over the last few years!

Argentina’s reserves and its debts: Central Bank robbery | The Economist

I received the following email from an Econ teacher who wonders if I had any insight on a question posed by one of his students:

The email reads: “I have alittle query i was hoping you could help clear up for me..a year 13 student has asked a question relating to Argentina’s prime minister, Cristina Fernandezde De Kirchner’s, decision to sell the central bank’s dollar reserves to fund part of the country’s decifit against the advice of the director of the central bank who resigned.”

The student’s question is on the following passage from the Economist article above:

Fernández (Argentina’s president”) justified her raid on the reserves by saying that the Central Bank had more than it needed, because they exceeded the size of the monetary base. Economists disagree about what is an appropriate target for the reserves, but Mr Redrado’s view is that a highly dollarised emerging economy like Argentina’s needs an abundance of Treasury bonds (the form in which most reserves are held) as insurance. Even if Ms Fernández might find support from some economists for her argument, her plan to swap the dollar reserves for a non-transferable government bond would not.

The student’s question is: “I do not know what a monetary base is, nor why Argetina needs treasury bonds.”

This article really caught me off guard at first as well. One thing I love about the Economist newspaper is its use of economic jargon that requires a real understanding of the subject to be able to interpret. The first time I read the article, I will be honest I was completely confused as to what the Argentinean president was up to. But after some reflection and rough sketches of graphs on scrap paper, I think I have “translated” the article’s jargon into plain English.

Below is my reply to the teacher and his student:

Hello,

The president of Argentina wants to sell the country’s US dollar reserves, which are held in the form of US treasury bonds, and then use the US dollars she receives to buy Argentinean government bonds in order to finance her own government’s budget deficit. In essence she wants to swap Argentina’s central bank reserves of US debt (considered a very stable and safe asset due to America’s low inflation rate and relative solvency of the US government) for Argentinean government debt (less stable and safe, especially in the wake of the country’s 2002 default on its debt). Argentina’s central bank would then hold fewer transferable, stable US bonds and more “non-transferable”, Argentinean government bonds. And since the bonds represent Argentina’s government debt, the country as a whole reduces its assets and increases its liabilities.

It is important for a developing country like Argentina to keep large reserves of US dollar-denominated assets (i.e. US treasury bonds) in reserve in order to assure foreign investors that the country would be able to stabilize its currency’s value in the face of a currency crisis such as that which Argentina experienced in 2001-2002. If the value of the peso began to decline on foreign exchange markets (due, for instance, to a decline in international investor confidence in the government’s ability to pay the interest on its foreign debt or inflation fears caused by excessive monetary growth or government spending) then the central bank could use its large dollar reserves to intervene in the forex market and stabilize the value of the peso, reestablishing investor confidence and maintaining the government’s ability to attract foreign creditors in the Argentinean bond market. A collapse of the peso would have ripple effects throughout Argentina, driving up imported products and raw materials and causing spiraling inflation, forcing the government to print more money to finance its budget in the face of falling demand for its debt in domestic and international bond markets.

Argentina must be sure to keep its balance sheet (i.e. its liability to asset ratio) in check. Its assets are US government bonds, its liabilities are the Argentinean bonds it issues to finance its budget deficits. If this ratio become too heavy on the liability side, foreign investors and speculators will lose confidence in the both peso and the Argentinean government’s solvency and dump their holdings of Argentinean currency, assets, and bonds, driving interest rates through the roof and the exchange rate through the floor, grinding the economy to a halt.

The article says,

Argentina’s economy is on course to rebound this year and grow at 3-5%. But the government is spending money so fast that this growth will not finance current spending on its own, says Daniel Marx, a former finance minister. Ordinarily, a government faced with a shortfall would turn to domestic and international bond markets. But this has been difficult since Argentina defaulted in 2002.

The country cannot count on private creditors to make up its budget shortfall, so the president is planning to finance her country’s deficit by buying Argentinean bonds with the country’s own US dollar reserves. Such behavior concerns economists because it could send a message to international investors that the country is on the path towards another unsustainable build-up of debt that could culminate in another default and economic collapse. The article is a word of caution to the president that all leaders should heed: balanced budgets are a good idea, and debt is dangerous!

Obamas Efforts To Boost Exports Face Hurdles : NPR

President Obama thinks the key to recovering the millions of American jobs lost during the recession lies in boosting exports to the rest of the world:

The plan sounds great. As we learn in AP and IB Economics, free trade leads to benefits for nations that choose to participate in it. Of course, promoting free trade will harm some industries and workers whose jobs end up being “off-shored” or “out-sourced” to countries with cheaper or more qualified labor; but Obama’s hope is that promoting free trade will result in a net gain of 2 million American jobs.

The goal of doubling US exports in 5 years, however, may be overly ambitious. According to the CIA World Factbook, the US is currently the fourth largest exporter in the world, sending just around $1 trillion worth of goods and services abroad in 2009, behind the EU with $1.9 trillion, China with $1.2 trillion and Germany with $1.18 trillion of exports. Obama’s goal to double US exports would propel the US to the single largest exporting nation in the world, putting it right around where the 27 nations of the European Union are today.

To achieve his goal, Obama proposals include three strategies for boosting demand and supply of US exports.

• On the supply side he suggests continuing recent guarantees for payment by foreign buyers. Essentially such a scheme reduces the risks that often accompany international commerce, reducing the “costs” of exporting firms, which in essence increases the supply of exports from the US.
• On the demand side the US must pressure China to revalue its currency. A stronger RMB (and a weaker dollar) will increase China’s demand for US goods and services.
• Also on the demand side, the US should push through free trade agreements with South Korea, Panama and Columbia, which have encountered obstacles among US lawmakers who fear that more free trade may actually mean a loss of US jobs.

Free trade agreements, export payment guarantees and a weaker US dollar in China will help Obama reach his goal. Chances are, however, that it will ultimately be unattainable. Doubling US exports would propel the US to the top of the list of exporting countries, surpassing even China, today’s current leader, by $700 billion more than the country exported last year. The impact on US GDP would undoubtedly be enormous, adding upwards of  $1 trillion to the US economy.

Creating jobs through trade is controversial, as many Americans still believe trade is partially to blame for the loss of American jobs in recent years.

“The average voter in the U.S. has been pretty on the fence about whether they want more trade coming into the United States,” Slaughter says. “The income pressures that a lot of households have faced in recent years have sort of shifted that balance where more voters now are a lot more wary of globalization than they used to be.”

While his goal is lofty, Obama is on the right track towards growing the US economy and promoting job creation. Trade benefits Americans not just because it will increase demand for our goods and services abroad, but because it will lead to lower prices for many of the things we enjoy consuming at home, ultimately increasing real incomes in America while also creating jobs.

The graph below presents a simple explanation of how the above strategies can result in more jobs in US export industries.

Discussion Questions:

1. How does China manipulate the value of its currency? Why is such manipulation harmful to US exporters?
2. How does a government payment guarantee for exporters actually reduce the costs of doing business for US exporting firms?
3. Do you believe that more free trade agreements with countries like South Korea and Panama will create jobs or destroy jobs in the United States? Explain.

More misleading economic statements from uninformed people who have never taken an economics course!

What about, you say?

I’m glad you asked!

I often read and hear in the American press that the United States is creating a giant wealth transfer by buying oil from other countries. Those “wealth transfer” words imply to the typical citizen that somehow our U.S. money supply is leaving our country, never to return again, and somehow our country is pooer after the transaction than if we had produced the oil within our own country.

Yes, the other country becomes wealthier but it has nothing to do with the US currency we send them, for, after all, the US dollars are only useless paper in their own economies as the US dollars cannot be spent in their own economy, but rather those same US dollars can be used to gain access to the US goods and services that those countries covet! The US also becomes financially better off due to the “trade” as the US can aquire our culturally, covetable and inexpensive oil to fuel our cars and heat our homes, in return for the various US products and services traded to the countries from which we imported the oil. In effect, we have “traded”, just like the old western cowboys & indians, US goods for oil, and both countries are better off!

Let me clear about one thing, however; I am fairly confident that it is NOT in our best homeland security interest in purchasing such a large share of oil purchases from countries like Saudi Arabia and Venezuela, whose loyalty to our country is certainly questionable. Luckily, the U.S. produces 40% of its own oil consumed and the other 60% consumed is imported from many different countries. Canada and Mexico are the two largest import countries, which is pretty darn safe.

However, ignoring the aforementioned security issue, when we buy from any of these countries, both countries benefit equally and there is NO transfer of wealth. When the U.S. buys oil from another country those U.S. dollars paid on the oil purchase are immediately returned to the United States and are spent almost immediately in our country since the other country cannot use our dollars in their country. What is really happening is that both countries’ citizens GAIN (not lose!) equally as we are, in essence, trading one product for another for both countries to enjoy!

Let’s use an example. Let’s say the U.S. buys 1000 barrels of oil from Saudi Arabia. At today’s oil price per barrel of $75 that would mean the U.S. would pay Saudi Arabia $75,000 and Saudi Arabia would then, in turn, be forced to turn around and use the paper ($75,000 USD!) on say, a bunch of iPods from Apple. Yes, the Saudi’s are listening to “I Kissed a Girl” by Katy Perry with their IPods hidden under those smart head robes they wear! Ladies and gentlemen: that is why they call it trade: the essence of the transaction is that we have traded some of our iPods for some oil to fuel our cars and heat our homes. Both of us have gained! Katy Perry is hot on the charts and the Saudi’s are boogying in the streets, as US citizens can now drive freely to 7-Eleven for a Big Gulp and stay warm in the winter with the oil received in return.

Also, think of it this way: when an American buys a gallon of gas the money is, ultimately, going to an American business such as Apple! All spending of US dollars is spent back into our economy, and all spending of Saudi dollars (actually they call their currency the “dollar” also but it doesn’t look like ours!) benefit the Saudi economy.

Yes, trade is mutually beneficial. I would rather a warm home this winter and forego another Katy Perry song!

Questions for Discussion:

1. Have you ever realized why they call it “trade”? That each country cannot use the other country’s currency so, in essence, there is a simply a trade of only products and services.

2. The US has a large trade deficit with China and Japan. Why is China and Japan holding on to US dollars and not spending it back into the US? Have they thrown the US dollars away?

3. Do you believe that free trade is a win-win always? If not, why not? Why do nations interfere (tariffs, quotas, etc.) with trade if it is so beneficial?

In IB Economics unit 5, Development Economics, several strategies for achieving improvements in the welfare of the world’s poorest people are investigated. Foreign aid has been one of the main focuses of economic development strategies over the last several decades. But is aid in the form of development loans and grants from international organizations and foreign governments always beneficial to those who receive it in the poorest countries (the bottom billion as described by development economist Paul Collier)?

In the discussion that follows, Paul Collier of Oxford and Zambian economist Dambisa Moyo argue that the developed world’s focus on aid to Africa, resulting in a trillion dollars in loans and grants over the last 50 years, has missed the mark and completely failed to achieve meaningful economic development. The focus must therefore shift to opening markets, improving governance, achieving security and creating jobs for the poorest people on the African continent. Watch the two videos below, and respond to the discussion questions that follow. [the time in the video where the question is discussed is in brackets]

Part 1:

Part 2:

Discussion Questions:

Part 1:

1. What factors does Paul Collier point to that contribute to the “poverty traps” many African nations find themselves in? [3:07]
2. What have the two main goals of foreign aid policy been over the last 50 years, according to Dambisa Moyo? [4:45]
3. What are the “four horsemen of the African apocalypse?” How does Moyo think these four obstacles to development can best be overcome? [5:14]
4. What is Paul Collier’s opinion of the role of free trade in promoting human and economic development in Africa? What does he think about Africa’s traditional dependence on primary products and commodities? [7:45]
5. Before economic growth and development can occur, security must be achieved. Why is security, according to Collier, the number one obstacle to achieving meaningful development in Africa? [8:30]
6. In a dissenting view, Dr. Jeffery Sachs argues for more aid to Africa. What types of aid does Sachs believe is absolutely crucial for Africa to continue to receive? [10:39]

Part 2:

1. Collier makes the claim that aid may create “moral hazard” in Africa. What is moral hazard and how could reducing aid to African governments actually “force good governance”? [5:30]
2. Is there any historic record of aid working? What strategies accompanied foreign aid that contributed to its greatest historical success? [8:10]
3. What’s the main difference between Europe’s economic successful development during the second half of the 20th century and Africa’s unsuccessful experience during the same period? [9:00]
