As a culminating activity for the two year IB Economics course here at Zurich International School, senior econ students research, prepared and presented proposals to the World Bank. The purpose was to choose a developing country, identify its current development status, pinpoint the major obstacles to development, brainstorm the country’s major assets and areas of potential, then request funds for a specific development project aimed at improving human welfare in the country.

Proposals ranged from transportation infrastructure to language schools to fair trade schemes to improvements in police protection. In the table below all 22 of my students’ projects can be viewed by clicking on the country’s name and following the link to the student’s presentation. Also below I have embedded some of the presentations for you to browse and evaluate here.

Samples of students’ presentations:

The assignment:

Goal: To win a concessionary loan from the World Bank to put towards a specific development project in the developing country you represent. Funds are extremely limited, and whether or not you will receive aid and how much aid you receive will be determined by a panel of judges consisting of your classmates.

Background: You will assume the role of Finance Minister for a country that you chose to research earlier in this unit. In that role, you will write a detailed report of your country’s development status, obstacles to economic development, existing resources and potential within the country, concluding with a proposal for a specific development project that will improve human welfare in your country. You will then make an appeal to lenders at the World Bank, requesting funding for your project. A committee made up of your classmates will decide whether to approve requests and bring them to the chief economist of the bank, your teacher. The best proposals (accurate, appropriate, achievable) will get the limited money available…and those students will earn the best marks.

Assignment:You will create a report for the country you selected in our earlier lesson, “Sources of Economic Growth and Development”. You will have class time over the next three weeks to research and prepare your report. The report may take any form you wish: It can be a written report to be delivered orally, it may be in the form of a Google Presentation, or it could be a video, such as a PhotoStory. You may also create a website containing the details of your report, or even an audio recording that could be podcasted in your appeal for financial support. Any other reasonable media may be used to prepare and present the report.

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

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]

Introduction: In order to understand the goals of economic development, it is useful to examine the characteristics of more economically developed countries and compare them to those of less economically developed countries.

Resources:

• Statistics – Human Development Reports (UNDP): http://hdr.undp.org/en/statistics/

• CIA – The World Factbook: https://www.cia.gov/library/publications/the-world-factbook/index.html

Indicator	Country with high HDI	Country with low HDI
HDI ranking and value
Age structure (dependency ratio)
Population growth rate:
School life expectancy
Life expectancy at birth:
Total fertility rate:
Education expenditures:

Economic Indicators:

Indicator	Country with high HDI	Country with low HDI
GDP per capita
GDP – composition by sector
Unemployment rate
Public debt
Stock of direct foreign investment – at home:
Household income or consumption by percentage share:
Labor force – by occupation:

Part 2 – Dependency Ratio: A nation’s dependency ratio tells us something about the ability of members of a nation’s workforce to provide necessities to him or herself and his or her dependents. Typically, less economically developed nations will have a higher dependency ratio than more economically developed countries. The lower a nation’s dependency ratio, the greater capacity for its workers to accumulate savings, which leads to investment, accumulation of capital, greater productivity, higher incomes and more economic development.

Calculation the dependency ratio: To calculate a nation’s dependency ratio, you must find demographic information on its population. You may need to do additional research beyond the two websites above to find this data.

Calculate the dependency ratios for:

1. Your country with high HD:
2. Your country with low HD:

Part 3 – Lorenz Curve and Gini coefficient:

• The Lorenz curve is a graphical representation of the income distribution of a country. It plots the percentage of a nation’s total income (GDP) against its total population. The “line of absolute equality” is the 45 degree line, indicating a nation where each quintile (20% of the population) earns exactly the same income as each other quintile. No country is absolutely equal, therefore the line of equality is only used for comparison.
• The Gini coefficient is the ratio of the area below the line of equality and above a country’s Lorenz curve and the total area of the triangle below the line of equality. A country with perfect income equality would have a Gini coefficient of 0. A country in which the top 1% had controlled all of a nation’s income would have a Gini coefficient of nearly 1.

Example: Australia’s income is distributed across its population in the following way:

• 1st 20% – 5.9%
• 2nd 20% – 12%
• 3rd 20% – 17.2%
• 4th 20% – 23.6%
• 5th 20% – 41.3%
• Gini coefficient = 0.352

Illustrating your countries’ Lorenz Curves: This is another activity that may require research beyond the websites provided above. Try to find data on the share of national income earned by various levels of society. If you cannot find data for the 20% ranges, use the percentage ranges you can find. Draw a Lorenz curve for the two countries you researched.

Part 4 – Conclusions:

Evaluate your findings from the two countries you researched. What conclusions can you draw about the correlation between GDP, HDI, income equality, social and economic indicators between developed and developing countries? Does a high HDI correlate with relative income equality? What about low HDI? Is a high GDP indicative of high levels of human development? What other conclusions can you draw about economic development, national income, and equality?

To what extent did your country with low HD exhibit the following characteristics? Low standards of living? Low incomes? Inequality? Poor health? Inadequate education? Low levels of productivity? High rates of population growth and dependency burdens? High levels of unemployment? Dependence on agricultural production and primary product exports? Imperfect markets? Dependency on foreign developed countries for trade, access to technology, foreign investment and aid?

Learning Objectives:

• Distinguish between fixed and variable costs of production
• Understand how the law of diminishing returns affects the shape of a firm’s short-run total costs and short-run average costs.
• Understand the relationships between marginal cost and the average costs faced by a firm
• Distinguish between the short-run and the long-run and understand how economies of scale determines the shape of a firm’s long-run ATC curve.
• Evaluate the importance to a business firm of understanding its short-run and long-run costs of production.
  

Success Indicators: Each team will create one Google Doc Presentation on costs of production. The two presentations that are created will be shared among group members, and edited as a team in class and over the weekend. Next week both teams will share their presentation with the class, and share them so that everyone can use the presentations to study for next week’s test on Costs of Production.

Process:

1. Place students into four teams.
   • Teams 1 and 2 will research and prepare a presentation on Short-run Costs of Production
   • Teams 3 and 4 will research and prepare a presentation on Long-run Costs of Production
   • Teams will work independently. On presentation day, a team presenting on short-run costs will partner with a team that did long-run costs and combine their presentations into one. Ultimately, two presentations will be submitted to Mr. Welker for review.
2. One person from the table will go to the website: http://docs.google.com/
3. That person should log in to Google Docs using his/her Google account
4. Once logged into Google Docs, select “Presentation” from the “Create New” drop-down menu. Title the presentation either “Short-run Costs of Production” or “Long-run Costs of Production”. Include teammates names on the first slide.
5. Next, the person who created the Presentation must invite his/her teammates to the presentation so everyone can contribute to it. Go to the upper right hand corner of the screen and click “Share” and “Invite people”. Enter the email addresses of your teammates and make sure the bubble “to edit” is selected. Click “Send”.
6. All teammates must check their email and make sure they received an invitation to edit the presentation. If you do not have a Google account, you may need to create one to get access to the document.

The assignment: Each team is to make one Google Presentation on an assigned topic based on what they learn using the web-resources provided by Mr. Welker below. Presentations will be shared with Mr. Welker and presented to the class on Tuesday, December 1.

Topic: The Marshall Lerner Condition and the J-Curve

Learning Goals/Objectives:

• For students to understand that the levels of price elasticity of demand for a country’s imports and exports determines whether a depreciation or devaluation of the country’s currency will move the nation’s balance of payments towards a surplus or a deficit.
• For students to understand the impact of time on the effect of a depreciation or devaluation of a nation’s currency on its balance of payments in the current account.
• For students to evaluate the argument that a country will always benefit from a weaker currency.

Success Indicators:

• Students will present their PowerPoint presentations of their exchange rate research, explaining how elasticity, exchange rates, and the balance of payments are related.
  
• Students will be able to outline their answers to three IB Economics examination questions relating to the Marshall Lerner Condition
  

Test of prior knowledge:

1. Define ‘price elasticity of demand’ and explain how it is measured.
2. With the use of examples, explain why some products have low price elasticity while others have a high elasticity. With the use of examples, explain why the price elasticity of demand for some goods changes over time
3. Explain how the depreciation of a country’s exchange rate might affect its current account balance.
   IS THIS ALWAYS THE CASE?
4. How might the PED for exports and imports influence the balance on the current account following a change in the value of a nation’s currency?

Process: Students should work in groups of four

• Each group chooses two countries
  • US and Canada
  • Switzerland and Great Britain
  • Euro area and Japan
  • Brazil and US
• Complete three pre-readings:
  • From BizEd:
    The Marshall Lerner Condition and The Economic Effects of a Devaluation
  • From Welker’s blog: The Marshall Lerner Condition and the J-Curve
    
• Using Yahoo Finance, research exchange rate data from the two countries two years ago up to today.
• Use Yahoo’s software to create two line graphs plotting the value of Country A’s currency against Country B’s, and Country B’s against Country A’s. For example:

The exchange rate of US dollars in Australia

The exchange rate of Australian dollars in the US:

• Finally, Create a PowerPoint presentation of your answers to the following questions. Include in the presentation the graph of the exchange rates created in the step above.

Of the four members of each group, two should prepare the section of the PowerPoint answering the following questions from the perspective of Country A and two from the perspective of Country B

Country A: ____________________ and ______________________

Country B: ____________________ and ______________________

Questions the PowerPoint should answer:

1. What is the Marshall Lerner Condition? Why is it important to consider the price elasticities of demand for exports and imports when examining the impact of a change in exchange rates on the current account balance?
   
2. Describe two periods of time from your line graph: One in which your country’s currency strengthened and one in which it weakened against the other country’s currency.
   
3. Using your knowledge of economics, explain TWO factors that may have caused the changes you have identified.
   
4. Given the changes identified, what would you predict would be happening to your country’s current account of the balance of payments over the three periods you specified above?
   
   1. Period 1: _______________________
      
   2. Period 2: _______________________
5. For both the periods of change, explain the impact of the change in exchange rates on the following:
   
   1. a firm that imports its raw materials from the other country
      
   2. a firm that exports its finished products to the other country
      
   3. consumers who buy imports from the other country
      
   4. a firm that produces good for the domestic market and competes with firms from the other country
      
6. Consider the impact of changes in the exchange rate on amount spent on imports and the revenue earned from exports (and thus, the current account balance). Assume the following for the three periods from your chart:
   
   1. Period 1: The price elasticity of demand for imports is 0.35 and the price elasticity of demand for exports is 0.55.
      
      1. Import spending will __________________
         
      2. Export revenue will __________________
         
      3. The current account will move towards DEFICIT or SURPLUS (identify which)
         
      4. Is the Marshall Lerner Condition met? Explain
         
   2. Period 2: The price elasticity of demand for imports is 0.5 and the price elasticity of demand for exports is 2.6.
      1. Import spending will __________________
      2. Export revenue will __________________
      3. The current account will move towards DEFICIT or SURPLUS (identify which)
      4. Is the Marshall Lerner Condition met? Explain
7. Think about the period in which your country’s currency weakened. Assume that the currency remains weak. How would the balance on the current account change over time following the depreciation of the country’s currency. Draw a J-Curve and explain its shape, referring to your country’s currency.
8. Look at the following article: ‘How Far Will the Dollar Fall?’ by Richard W. Rahn.
   1. Explain how the fall in the dollar might help to reduce the US trade deficit.
   2. Assess Dr Rahn’s argument that taxation and regulation are the principle causes of the potential for the limits to growth in the world economy.

You’re now prepared to consider the elasticity implications for balance of payments. Test your own understanding of the Marshall Lerner condition by answering the following IB questions:

1. With reference to the Marshall-Lerner condition, explain how the depreciation of a country’s exchange rate might affect its current account balance. (Total 10 marks)
2. An economy is currently experiencing a deficit on the current account of its balance of payments. The government is considering either allowing the exchange rate to fall or reducing aggregate demand. Evaluate the relative advantages and disadvantages of these two policies. (15 marks)
3. Explain how, in theory, balance of payments deficits and surpluses on current account are automatically adjusted under a system of flexible exchange rates. Illustrate your answer using supply and demand analysis. (Total 10 marks)

The above lesson was inspired by the Biz-Ed activity “International Trade: The Falling Dollar or Rising Pound?”

4. At which price(s) would this firm be earning economic profits when producing at quantity Q1? Explain.
5. At which price(s) would this firm shut down when producing at Q1? Explain

IB Question of the week:

1. Explain how, in theory, a flexible exchange rate system should lead to the automatic stabilization of a nation’s current account balance. Use supply and demand diagrams to illustrate your answer
2. Referencing the Marshal Lerner Condition, explain the possible effects of a depreciation of a nation’s currency on its current account balance.

Harvard’s Greg Mankiw just keep them coming! Here’s another micro problem from the esteemed professor and textbook author’s blog. Several readers enjoyed challenging themselves with his last Micro problem, so I will re-publish Mankiw’s test question here to see if people can solve it in the comment section on this blog (sorry Professor Mankiw, you have comments turned off on your blog, so how are your readers to know if they have solved it correctly?)

The town of Wiknam has 5 residents whose only activity is producing and consuming fish. They produce fish in two ways. Each person who works on a fish farm raises 2 fish per day. Each person who goes fishing in the town lake catches X fish per day. X depends on N, the number of residents fishing in the lake. In particular,

X = 6 – N.

Each resident is attracted to the job that pays more fish.

a. Why do you suppose that X, the productivity of each fisherman, falls as N, the number of fishermen, rises? What economic term would you use to describe the fish in the town lake? Would the same description apply to the fish from the farms? Explain.

b. The town’s Freedom Party thinks every individual should have the right to choose between fishing in the lake and farming without government interference. Under its policy, how many of the residents would fish in the lake and how many would work on fish farms? How many fish are produced?

c. The town’s Efficiency Party thinks Wiknam should produce as many fish as it can. To achieve this goal, how many of the residents should fish in the lake and how many should work on the farms? (Hint: Create a table that shows the number of fish produced—on farms, from the lake, and in total—for each N from 0 to 5.)

d. The Efficiency Party proposes achieving its goal by taxing each person fishing in the lake by an amount equal to T fish per day and distributing the proceeds equally among all Wiknam residents. Calculate the value of T that would yield the outcome you derived in part (c).

e. Compared with the Freedom Party’s hands-off policy, who benefits and who loses from the imposition of the Efficiency Party’s fishing tax?

I love that Harvard Economics professor Gregory Mankiw blogs, but I hate that has de-activated the comments on his blog. Yesterday he posted a question from his own Harvard introductory economics class.  Since he doesn’t allow comments though, I cannot tell if I’m solving it correctly. So I will re-publish it here and ask my readers to solve the problem in the comment section.

IB and AP students who have studied microeconomic should be able to put some of their basic algebra skills to work to solve this one.

Only one firm produces and sells soccer balls in the country of Wiknam, and as the story begins, international trade in soccer balls is prohibited. The following equations describe the monopolist’s demand, marginal revenue, total cost, and marginal cost:

Demand: P = 10 – Q
Marginal Revenue: MR = 10 – 2Q
Total Cost: TC = 3 + Q + 0.5 Q^2
Marginal Cost: MC = 1 + Q

where Q is quantity and P is the price measured in Wiknamian dollars.

a. How many soccer balls does the monopolist produce? At what price are they sold? What is the monopolist’s profit?

b. One day, the King of Wiknam decrees that henceforth there will be free trade—either imports or exports— of soccer balls at the world price of $6. The firm is now a price taker. What happens to domestic production of soccer balls? To domestic consumption? Does Wiknam export or import soccer balls?

c. In our analysis of international trade in Chapter 9, a country becomes an exporter when the price without trade is below the world price and an importer when the price without trade is above the world price. Does that conclusion hold in your answers to parts (a) and (b)? Explain.

d. Suppose that the world price was not $6 but, instead, happened to be exactly the same as the domestic price without trade as determined in part (a). Would anything have changed when trade was permitted? Explain.

Post your solutions below, I really want to know if I have solved it correctly!

Traditionally, less than 5% of young girls complete primary school in Muhuru Bay. In the town’s history, only ONE girl has ever gone to university (she would become the only Muhuru Bay native to complete her PhD and would eventually co-found WISER with Andrew). A combination of tradition, culture, and most importantly poverty had prevented improvements in the plight of woman in this poor corner of Africa. What was needed, decided Andrew and his founding partners, was an all-girls boarding school where opportunities for young women were promoted and academic achievement encouraged and fostered. WISER will open the community’s first all-girls secondary school this January and welcome 130 girls who have successfully competed primary school, an event representing a major step in the reduction of poverty in Muhuru Bay.

Beyond female education, Andrew and WISER have embarked on several other development projects in the last year and a half. In his visit to our IB Economics class last week, Andrew told the story of human development in Muhuru Bay as occurring primarily in three realms. Education, health, and entrepreneurship. Andrew is an amazing, dynamic, inspirational speaker, and his lectures in my class cannot be done justice in a blog post; but the lessons learned during his visit are worth recording here for others to learn from and to document for future use in my own classes. I will briefly summarize the three main development strategies Andrew and WISER have employed in Muhuru Bay, starting with education.

Education as a development strategy:

It should come as no surprise to this blog’s readers that education is a primary and fundamental strategy for eradicating poverty. A nation’s human capital is its most vital resource, and the road to prosperity requires an effective education system that does not discriminate based on race, gender, or socioeconomic status. In Muhuru Bay, which is 14 hours by car across un-paved roads from the Kenya’s capitol, the education system had failed to achieve meaningful results, both for boys and girls. Student performance on national examinations across the primary grade levels had historically averaged around 11% passing rates. Boys out-performed girls, but as a whole only about one in ten Muhuru Bay children passed the examination required for admittance to secondary school in Kenya.

Andrew and WISER needed to improve this dismal statistic. If they were going to build a secondary school for girls, they would need to first get girls to pass the national exam for entrance to secondary school, or else their new building would be full of empty desks. Andrew first talked to my class about the traditional development community (think World Bank, UNICEF, USAID) approach to promoting education in Africa. You are probably thinking the way to help these kids is to give them resources to improve their education. Build better schools, give them textbooks and school supplies, maybe uniforms, build a library, electricity in the classroom, chalk boards, heck, how about we give them laptop computers! All of these ideas represent the traditional development community’s approach to improving education in poor countries. The problem, according to Andy, is that these strategies focus only on the inputs into education, and completely fail to look at the output.

Inputs and outputs are common topics of discussion in any Economics class. To produce anything, three resources are required: land, labor, and capital. The traditional approach to improving education in Africa focused primarily on the land and capital. Things such as pens, notebooks, laptops, and new libraries are great, but they have little actual impact on what gets learned in a school. The neglected factor was the labor (i.e. the teachers!) In Muhuru Bay, teachers were paid so miserably and worked in such dismal conditions that the incentive to actually improve their students’ results was just too weak! With passing rates at 11% on national exams, Andrew and his team set about figuring out how to use incentives to improve the outputs of education in Muhuru Bay.

A simple and relatively low-cost plan was put into action. Teachers were told that if their students’ scores increased by only 15% on the exams, they would receive a 100% increase in their salary. Andrew and WISER worked with the national education ministry to develop interim exams that could be given quarterly to help the teachers measure their students’ improvement before the annual national examination. Wouldn’t you know it, with only minimal investments on the land and capital resources (i.e. textbooks and classroom materials) in Muhuru Bay schools, and by spending less than $10,000 on teacher raises, the passing rate among Muhuru Bay schools increased this year to 36% from last year’s 11%. Hundreds of students, boys and girls, who would not have been able to enter secondary school the previous year, instead passed the exam and were eligible for a secondary education, a crucial step towards a better future!

The teachers’ incentive pay program was such a success in Muhuru Bay last year that the state government has taken notice and intends to implement it in other rural communities throughout Kenya. By focusing on the outputs (student learning), rather than the inputs (classroom resources) Andrew and WISER have assured that when their all-girls school opens in January, its seats will be filled with qualified students who successfully completed their primary education.

Health as a development strategy:

The second topic of Andrew’s discussion with my IB Economics classes focused on health and sanitation, specifically solving the problem of open defecation (“OD” is a technical term used in the development community referring to the fact that in many poor communities basic latrines are non-existent, and therefore people shit in the open). OD in Muhuru Bay contributed to the poor health and low life expectancy of locals; According to Andrew an estimated 60 people have died this year of cholera, a disease spread via human waste.

In the health realm of development, the same basic dilemma between focusing on the inputs or the outputs had stymied previous attempts to reduce OD in Muhuru Bay. Recently, an outside aid organization had made loans to the community to build 30 public latrines. Within a year, however, the latrines had fallen into disrepair and were essentially useless. When Andrew and his team asked the community members why they had let the latrines fall into such a poor state, their answer was predictable. These were not their latrines, they belonged to the aid organization that had built the latrines… If they were broken, the aid organization could fix them! Such logic reflects a common problem in economics, that of the tragedy of the commons. Because the latrines were public, no one owned them. Because no one owned them, no one cared for them. When the latrines fell out of repair, people quickly reverted back to OD, and instances of cholera and other diseases increased once more.

Andy and WISER decided to tackle this problem using a similar approach as the one used to fix primary education in Muhuru Bay, by focusing on the output, rather than the inputs. In this case, the goal was simple: create incentives for people to build their OWN latrines, which they would then have an incentive to take care of and use. The strategy for promoting personal latrines they decided to employ is one that has been successfully implemented throughout the developing world, and is now funded by UNICEF, which trains facilitators to go into a community and in a very short time, and at a very low cost, incentivize the locals to take sanitation into their own hands and build their own latrines.

Community Led Total Sanitation (CLTS) is a mind-blowing and shockingly blunt way to promote sanitation. Rather than spending thousands of dollars to build public latrines, the CLTS approach brings community members together for an afternoon of discussion and education about sanitation issues. Locals are asked to take an index card and go to “where they shit” and collect a sample of their own waste. A large pile of shit is placed on a table in front of a room full of locals right next to a large selection of delicious foods. The facilitator then goes about discussing basic facts related to shit in the community, such as “If you added up all the shit your community produces in a year, how many donkeys would it weigh as much as?” or, “How many bags of rice would you have to eat to create this much shit?” In the mean time, of course, hundreds of flies have descended on the pile of shit in the front of the room, and the community members look on in utter disgust as the flies jump from the feces to the food and back again.

At the end of the lecture, the facilitator turns to the food and says, “Well, it’s time for lunch, who’s hungry?” In utter disgust, the locals ask the facilitator if he has gone mad. The lesson, of course, is that the food and water the community consumes is most likely being contaminated by the shit they produce and deposit in the open around their village. Within a few weeks of the CLTS project in Muhuru Bay, 256 new latrines were built by the community members themselves. Whereas previously, only around 15% of the locals used latrines regularly, after the CLTS project around 75% had access to the “facilities”.

The total cost of the CLTS sanitation project? Around $55, a tiny fraction of the cost of building the public latrines that had previously been neglected by the community. By focusing on the outputs rather than the inputs, real development in the health of the community was achieved at a very low financial cost.

Entrepreneurship and micro-lending as a development strategy:

The final approach to human development in Muhuru Bay Andrew discussed with my classes focused on the economic empowerment of community entrepreneurs. Micro-lending is a much talked about and widely used development strategy that provides financial credit or technology loans to entrepreneurs in poor communities to create small businesses, ideally ones with a socially beneficial purpose. In Muhuru Bay, the micro-lending scheme Andrew has pioneered involved not financial capital, but physical capital (i.e. technology).

Andrew was able to secure several technology donations, including a copy machine, several laptop computers with cellular internet connections, a foot pump for water, and a digital LCD projector. WISER then solicited loan requests from several “young entrepreneurs”. Young men and women wrote business plans outlining how they would use the technology loans to generate income for themselves and the community, and provide services that would benefit others in the Muhuru Bay community. The technology would not be donated to the recipients; rather they would be required to pay back the value of the capital through their business revenues.

It is simply amazing how a few pieces of second-hand technology, items that we in the rich North would take for granted as relatively common and thus of very little social or economic value, can completely change a poor community in Africa for the better. Here’s how some of the capital Andrew and WISER loaned to young entrepreneurs were put to use to achieve meaningful development in Muhuru Bay:

• The copy machine was installed and powered by a generator. It was the first such machine ever installed in Muhuru Bay. Local businesses, students, job seekers and other could now, for a few cents, photo-copy their documents locally, avoiding the two hour drive previously required for such a service.
• The laptops were installed in an internet café and made available to local students and businesses. Farmers and fisherman could check product prices in the cities hours away, increasing efficiency and bargaining positions when middle men came to town to buy their produce. Job openings in the city newspapers’ classifieds could be printed and posted for the local community to see, improving information symmetry between the poor countryside and the cities where job opportunities existed. The cost of access to these services was cheap, yet the entrepreneurs who were granted the laptop loan were able to pay back the cost of the technology in no time at all, and the community as a whole benefited from their existence.
• My favorite entrepreneurial venture involved the LCD projector. This piece of technology, which now hangs from the ceiling of thousands of classrooms around the rich world, had never before been seen in Muhuru Bay. You may think it ended up in a classroom or in an office building, but no; the entrepreneurs who received the projector hooked it up to a satellite dish which captured and projected English Premier League football matches onto the wall of a large room in a local building. The business was to sell tickets to local football fans who were more than happy to pay and watch English football matches in full color on a wall-sized screen. Before the projector, dozens would have huddled around a tiny, ancient television with poor reception to watch football matches. The “football theater” business was the most successful of all, and paid back its loan fastest.

All three of these entrepreneurial endeavors were very low cost, using donated technologies. The reason for their successes, however, must be attributed to the model for implementation. They were not simply “given” to the community. Such a strategy would certainly have led to the same “tragedy of the commons” experienced when the outside aid organization funded the construction of public latrines. The capital would have been neglected and fallen into disrepair. By lending the technology to businesses, however, the incentive for innovative and socially beneficial ventures was created, and a business model was developed to best utilize the resources in a profit-earning, sustainable manner. With very little inputs, fantastic outputs were achieved, enriching not only the entrepreneurs, but the entire Muhuru Bay community.

Economic Development the WISER Way:

Andrew’s visit to Zurich International School was eye-opening in many ways. He brought to light both the successes of WISER and other community projects in rural Kenya, but also shined a light on the failures of the traditional development community’s agenda. When I think about the hundreds of billions of dollars that have been committed to economic development in Africa over the past decades, and on into future decades, I wonder whether the diplomats and the politicians in the “aid community” have any idea how much has been accomplished on the ground in places like Muhuru Bay thanks to community service leaders like Andy Cunningham.

With so little, so much can be accomplished. The poor of Africa and the world need resources, but more importantly they need education, health and sanitation, and business opportunities so that they can enjoy the benefits of development from the bottom up. Development aid, as it has traditionally been distributed, comes from the top down, through national governments. Waste and corruption are rampant, and typically only a fraction of what has been given ends up on the ground in places like Muhuru Bay. Even when it does, the tragedy of the commons often results in inefficiency and waste, as the “inputs” are managed and distributed from the top down, leading to uncertainty of ownership and misaligned incentives once the resources are on the ground. Perhaps aid from the outside is still needed, but Andy’s visit showed me and my students that something much more basic lies at the core of successful economic development. Education focusing on outputs rather than inputs, sanitation focusing on outputs rather than inputs, and entrepreneurship that empowers business leadership, have improved the lives of thousands in one Kenyan community. What could such a re-thinking of development strategies do for the rest of Africa and the developing world?

First, I have created a Diigo Group for Econ Teachers that is open for anyone to join. A Diigo group essentially is a social network for people with shared interests. The Econ Teacher group will be a place where Econ teachers can share bookmarks to online resources for use in the classroom. More than just a bookmarking site, however, Diigo allows users to annotate, highlight and leave sticky notes on articles, blogs, and other websites posted to the group, which can then be seen by group members, and further annotated. A website such as the CIA World Factbook, the BLS, or BEA, or an article from the Financial Times or Wall Street Journal thus becomes a shared document for discussion and reflection amongst any and all teachers who find it useful.

Diigo groups also have discussion forum features, so the Econ Teacher Group will become a forum for sharing collective research and resource ideas, as well as a forum for discussing how technology and the web can be used to enrich economics education. Join the Econ Teacher Diigo Group now to help grow this new social network for Econ teachers! (Once you’ve joined Diigo, I recommend adding the Diigo toolbar to your browser to make bookmarking and annotating sites to the group easy!)

Secondly, I am happy to endorse my friend and colleague Mike Fladien’s entrepreneurial endeavor aimed at helping high school Economics students prepare for their exams, “EconExamCram”. EconExamCram is an iPhone or iTouch App for sale in the iTunes store for $1.99. From the app’s description:

This app is available for download on iTunes. I intended this to aid students in preparing for tests in microeconomics. It’s a comprehensive review of 80% of the concepts covered in a micro class.

I believe that students today want to learn using today’s technology. Today’s technology is iPods, Smart Boards, audience response systems, flash animation and more. When I developed this app, I developed it for the on-the-go student who values appearance too. The student I envisioned was one who had a challenging schedule and one or more after school activities. They will carry an iPod with them, but not a five pound textbook. The student I envisioned was one who studied in “micro sessions” of 10 or 15 minutes. The touch was a natural tool for these students.

Congratulations to Mike on developing this app and making it available to us and our students to help prepare for the AP and IB Exams. Do your kids a favor and give them all the link to this app so they can start reviewing for your tests on their phones today!

The last great resource I have added to my sidebar this week is an RSS feed to a YouTube channel I’ve recently discovered. Jacob Clifford, an AP Economics teacher in San Diego, has recently begun producing and publishing a series of review videos for the AP Economics student. He calls them “Economic Concepts in 60 Seconds”.

Jacob is an enthusiastic, energetic young Econ teacher whose lecture style is fast paced and easy to follow. An since the lectures are on YouTube, students (and teachers!) can watch them over and over until his explanations of econ concepts is clear. In each video, he illustrates the concepts on a whiteboard while clearly (and quickly) explaining them in a fun and entertaining way. So far he has only produced videos up through perfect competition in the AP Micro course, but he promises to keep adding more throughout the school year.

You’ll be able to follow Jacob’s latest video posts by checking the RSS feed on my sidebar when visiting the blog. I’m hoping to team up with Jacob somehow in the future to get his videos a wider audience through this blog or in some other collaborative way.

Imagine you’re a poor farmer who has always had just enough to feed your family, with no surplus left over to sell. Then one day the government decides to grant your family and your neighbors enough land to grow your own food and plenty more to sell on the market. The government’s intention, of course, is for you to cultivate all your land, sell your surplus, generate income for your family to improve your quality of life, send your children to school and save for the future.

You’re the farmer. You’ve just been given land. What would you do?

1. Plant crops on all your land, harvest the crops, sell the surplus and enjoy the profits from your surplus?

OR

2. Plant crops on only part of your land, grow enough food to feed your family, and let the rest of the land lie uncultivated. You have no surplus, nothing to sell, and continue to live the way you always have lived: poorly.

The science of economics assumes that individuals always act rationally in their own self-interest. Self-interest is the ultimate motive of economic actors: firms are profit-maximizers, individuals are utility-maximizers. The theory of rational behavior would lead one to assume that the farmer would pursue option 1 above. But in Papua New Guinea, where the government recently relocated thousands of displaced farmers to new plots of land, it is more common for farmers to chose option 2:

“If they see me planting too much cocoa, they’ll do things to my land and my family, and they won’t bear fruit; really bad things; puripuri and other witchcraft.”

Such an avoidance of profit maximisation might have appeared economically irrational. But from the perspective of those villagers, putting in extra work just to make oneself a target for the jealousy of one’s neighbours would be highly irrational behaviour.

Economists need to re-think their assumptions on rational behavior. What appears irrational to one person may be perfectly rational to someone else, as in the case of the Papuan farmers who only plant half their land. Humans, it seems, are a bit more complicated than the cold, calculating arithmeticians economists have long assumed them to be.

In the wake of the largest economic crisis since the great depression, the assumption of rational actors interacting in rational markets has come into question. A new field of economics blending the traditional study of resource allocation in the market place and human psychology has arisen to tackle the challenge of better understaning the seemingly irrational behaviors of investors, buyers and sellers in today’s global economy:

One response to the current crisis has been a rise in the popularity of behavioural economics, which examines the psychological and emotional factors behind transactions. These models drop the assumption of the rational actor yet implicitly keep the same model of economic rationality at their heart. We may diverge from the path of rationality for all sorts of psychological reasons but only because emotion, Keynes’s famous “animal spirits”, clouds our judgment.

To break human behavior down to the basic pursuit of profits by producers and utility by consumers neglects to acknowledge the “animal spirits” within us all. Economics is entering a new era, in which psychology and markets are intertwined. Rational behavior will remain a basic assumption of the science, but a re-defining of what it means to be rational will allow economists to better understand the behaviors of individuals, investors and firms as the economy emerges from a slump Alan Greenspan might say was ushered in on a wave of irrational exuberance.

Discussion Questions:

1. Are economists wrong to assume that individuals always act rationally? Why do the Papuan farmers only use half their land? Are they stupid or lazy?
2. Can you think of any examples in which you or someone you know has done something that was not in his best economic self interest?
3. Is charity irrational? What about gift giving? If you calculated that the chance of getting caught steeling something you REALLY wanted was 0%, wouldn’t it be irrational NOT to steal? What would keep you from stealing that thing if you deemed it rational to do so?

Student have been downloading my free study guides for over two years, and even college students have benefited from the resources here. Just last week I received the following email from a former AP Econ student now studying business at Boston University:

Hey Mr. Welker, just wanted to let you know that I’m retaking economics for my business requirements… The pace is SO FAST! But I’m using your wikinomics as a study tool. It’s really helpful. In fact, all your former students here at BU admit that they use your study guides all the time because they’re often times better than the resources that BU gives us. I guess that’s something you can share to your current econ students!

For teachers, lecture notes in either SMART Notebook or PowerPoint format are available for purchase. Several teachers have already purchased my presentations and begun using them in their own classes. When you purchase a unit, it is yours to edit, re-format, enhance, and re-arrange anyway you wish.

This week’s cover story in Business Week magazine tells an interesting story about unemployment in America. Listen to the podcast or follow the link above to read more of this story:

Surprising statistic: In the midst of the worst recession in a generation or more, with 13 million people unemployed, there are approximately 3 million jobs that employers are actively recruiting for but so far have been unable to fill. That’s more job openings than the entire population of Mississippi.

Sound like good news? It’s not. Instead, it’s evidence of an emerging structural shift in the U.S. economy that has created serious mismatches between workers and employers. People thrown out of shrinking sectors such as construction, finance, and retail lack the skills and training for openings in growing fields including education, accounting, health care, and government. At the same time, the worst housing bust in decades has left the unemployed frozen in place. They can’t move to get work because they can’t sell their homes.

In IB and AP Economics we teach that there are three types of unemployment an economy may experience, ranked roughly in order from the least undesirable to the most undesirable (from a macroeconomic perspective):

• Frictional unemployment: This accounts for people who are “in between jobs” or fresh out of college looking for their first jobs.
• Structural unemployment: This is caused by the changing structure of an economy. As America’s manufacturing sector shrinks and its education and health care sectors grown, those whose skills lie in manufacturing become structurally unemployed.
• Cyclical unemployment: This is also called “demand-deficient” unemployment because it is caused by a fall in aggregate demand or overall spending in the economy.

America today is clearly experiencing all three types, but due to the particular circumstances of the recession, the American worker is finding it it harder than ever to match his skills with an appropriate job. Below are some of the industries with the most and the fewest job openings today:

Most openings:

• Education
• Health care
• Government
• Energy (such as wind, oil, natural gas)
• “Analytics” (i.e. business data analysis by firms such as IBM)

Fewest openings:

• Construction
• Manufacturing

Unfortunately for the large numbers of unemployed construction and factory workers, the kinds of skills required to work in the fields with the most job openings are prohibitively different from those learned in their previous industries. In addition to a mismatch of skills between the industries in which jobs are being lost and those in which labor is in demand, there is also a geographic mismatch in the labor market. Below are the states with the least and the most job openings:

Most job vacancies (states with large energy sectors: oil, natural gas and windmills)

• North Dakota
• Wyoming

Least job vacancies (states with large manufacturing and construction sectors)

• North Carolina
• California
• Michigan

Historically, the geographic factor has not posed an issue to American workers, and when jobs opened up in one part of the country, Americans would pack up and move where necessary to find work. Today, however, with the collapse of house prices, more and more Americans find themselves stuck with a house they can’t sell in a part of the country where they can’t find a job.

To paraphrase the podcast above, “the US in danger of looking like Europe. The European job market has been described as ‘sclerotic’; people don’t respond to want ads because of the generous long-term unemployment benefits offered by European governments. Europeans have historically been geographically immobile due to nationalist ties to their home countries.” Today, the US job market reflects some of the same “sclerosis” as that of Europe.

America is facing the perfect storm of unemployment. At the same time that the economy is undergoing its most significant structural change since the Industrial Revolution brought millions of American workers from the farm fields into factories, it is facing the most significant decline in private sector spending (consumption, investment and exports) since the great depression. Put this together with the relative immobility of the American worker caused by the housing crisis, and unemployment has climbed to its highest level in three decades.

This interesting story ends with a glimmer of hope for the American worker:

To fight this sclerosis, the White House is using $3.5 billion of the stimulus for training, while boosting support for community colleges. Classes for factory workers seeking entry-level health-care careers have shown some success.

The truth is, displaced workers may have to move down a few rungs as they switch careers because their skills are irrelevant in their new roles… Many laid-off Wall Street financial engineers still haven’t absorbed that, says Fred Wilson, a partner in Union Square Ventures, a New York venture capital firm. “For them to take a job that pays a lot less, they have to make a meaningful change in their lifestyle. And that is an issue.”

Employers need to bend as well, recognizing that the candidates they’re seeking may not exist. Mark Mehler, co-founder of CareerXRoads, a staffing strategy consulting firm in Kendall Park, N.J., tells employers: “You’re hiring potential….You’ve got to train them.”

A mismatch of work and workers is never a good thing. But smart policy—combined with realism on the part of employers and job seekers—can minimize the disruption.

Discussion Questions:

1. In what way may structural unemployment be a sign of a healthy economy, rather than a sick one?
2. Part of the Obama stimulus package includes increased benefits for unemployed Americans. How may this pose an obstacle to reducing unemployment in America?
3. Historically, the natural rate of unemployment in most European economies has been higher than that of the United States. Why is this?
4. Do you think America’s NRU will return to its historic level (4-6%) when the economy eventually recovers from the current crisis? Why or why not?
