6 EC1001 A - Macroeconomics I EC1001 A SECTION B Answer one and only one of the questions numbered 26 to 29. The maximum number of marks awarded for this Section is Answer both part (a) and (b). (a) Which is likely to have the larger effect on the CPI, a 2 percent increase in food or a 3 percent increase in diamond rings? Explain. (b) Explain what the productivity slowdown and speedup are. What do economists believe was the cause of the slowdown? 27. The market for insurance is very large, amounting to several percentage points of GDP. Why do you think a market for insurance exists at all? Students sitting this exam had the possibility of purchasing grade insurance, by sacrificing one mark with certainty, and increasing their mark by two should their (unadjusted) mark be below the median mark. If there are two groups of students, confident and worried, which of the two groups of students is more likely to purchase the insurance? What would a regression line with (unadjusted) mark on the horizontal axis and a dummy taking value 1 if the student has purchased insurance and 0 otherwise look like? Explain. 28. The following outline, illustrates a circular-flow diagram.

Explain carefully the various parts of the diagram, paying particular attention to whether equalities are identities or equilibrium conditions. 6
7 EC1001 A - Macroeconomics I EC1001 A 29. Answer both part (a) and part (b). (a) Economists agree that increases in the money supply growth rate increases inflation and that inflation is undesirable. So why have there been hyperinflations and how have they been ended? (b) Suppose a presidential candidate promises to increase the government budget surplus and claims that doing so will stop U.S. citizens from investing in foreign companies and increase the value of the dollar. Evaluate this promise. 7

(a) The 2 percent increase in food will increase the CPI by more because the portion of the market basket that is for food is much larger than the portion for diamond rings. (b) From 1959 to 1973 U.S. productivity grew at a rate of about 3.2 percent. From 1973 to 1995 it grew by about 1.5 percent. This lead to slower growth in real GDP per person, which would have been 50 percent higher if the slowdown had not occurred. Although the evidence is not decisive, it appears that the slowdown was due to a slowdown in technological progress. It is also possible that the period was simply a time of extraordinary growth. However, productivity growth has been higher at 2.6 percent since 1995, which corresponds with the growth of information technology and the internet. 27. Becasue people are risk averse (marginal decreasing utility of income) and insurance companies risk neutral (reasons include their better ability to diversify). worried students (either risk averse or not so bright) are more likely to purchase. The regression line should have negative slope.. 1
9 ID: A 28. This diagram should duplicate the essential characteristics of the diagram in the text, with an explanation of the meaning of each flow and each market. It is important that the student understands that the inner loop represents the flow of real goods and services and that the outer loop represents the corresponding flow of payments. 29. (a) Typically, the government in countries that had hyperinflation started with high spending, inadequate tax revenue, and limited ability to borrow. Therefore, they turned to the printing press to pay their bills. Massive and continued increases in the quantity of money led to hyperinflation, which ended when the governments instituted fiscal reforms eliminating the need for the inflation tax. (b) An increase in the government budget surplus will cause U.S. interest rates to fall. The decline in interest rates will increase domestic investment, but it will also cause Americans to look for higher returns abroad, which means that net capital outflow rises rather than falls as promised. To take advantage of these higher returns, Americans will supply more dollars in the foreign-currency exchange market and the dollar will depreciate rather than appreciate as promised. 2

Using it as a template, draw on your answer book (do not draw or write on the question paper itself) a circular flow diagram representing the interactions between households and firms in a simple economy. Explain carefully the various parts of the diagram, paying particular attention to whether equalities are identities or equilibrium conditions. 28. The market for insurance is very large, amounting to several percentage points of GDP. Why do you think a market for insurance exists at all? Students sitting this exam had the possibility of purchasing grade insurance, by sacrificing one mark with certainty, and increasing their mark by two should their (unadjusted) mark be below the median mark. If there are two groups of students, confident and worried, which of the two groups of students is more likely to purchase the insurance? What would a regression line with (unadjusted) mark on the horizontal axis and a dummy taking value 1 if the student has purchased insurance and 0 otherwise look like? Explain. 29.

(b) Explain what the productivity slowdown and speedup are. What do economists believe was the cause of the slowdown? 6

(a) Typically, the government in countries that had hyperinflation started with high spending, inadequate tax revenue, and limited ability to borrow. Therefore, they turned to the printing press to pay their bills. Massive and continued increases in the quantity of money led to hyperinflation, which ended when the governments instituted fiscal reforms eliminating the need for the inflation tax. (b) An increase in the government budget surplus will cause U.S. interest rates to fall. The decline in interest rates will increase domestic investment, but it will also cause Americans to look for higher returns abroad, which means that net capital outflow rises rather than falls as promised. To take advantage of these higher returns, Americans will supply more dollars in the foreign-currency exchange market and the dollar will depreciate rather than appreciate as promised. 1
25 ID: C 27. This diagram should duplicate the essential characteristics of the diagram in the text, with an explanation of the meaning of each flow and each market. It is important that the student understands that the inner loop represents the flow of real goods and services and that the outer loop represents the corresponding flow of payments. 28. Becasue people are risk averse (marginal decreasing utility of income) and insurance companies risk neutral (reasons include their better ability to diversify). worried students (either risk averse or not so bright) are more likely to purchase. The regression line should have negative slope (a) The 2 percent increase in food will increase the CPI by more because the portion of the market basket that is for food is much larger than the portion for diamond rings. (b) From 1959 to 1973 U.S. productivity grew at a rate of about 3.2 percent. From 1973 to 1995 it grew by about 1.5 percent. This lead to slower growth in real GDP per person, which would have been 50 percent higher if the slowdown had not occurred. Although the evidence is not decisive, it appears that the slowdown was due to a slowdown in technological progress. It is also possible that the period was simply a time of extraordinary growth. However, productivity growth has been higher at 2.6 percent since 1995, which corresponds with the growth of information technology and the internet. 2
