33. If mangoes cost India Rupees (INR) 10 each, a consumer spends his budget on fruits that he values more highly than mangoes. However, at a price of INR 4 per mango the consumer buys 20 mangoes. The total consumer surplus (in INR) is closest to:

A. 26.
B. 60.
C. 120.

Answer: B
“Efficiency and Equity”, Michael Parkin 2009 Modular Level I, Volume 2, pp. 40-41
Study Session 4-14-b
Distinguish between the price and the value of a product and explain the demand curve and consumer surplus.
The consumer surplus is the value of the good minus the price paid for it (10-4) = 6, summed over the quantity bought. The total consumer surplus is the consumer surplus on each mango that the consumer buys and added together. It is the area of the right triangle = (base x height) / 2 as in Fig.2 on p. 40, with base equal to 20 mangoes a week and the height equal to 6, the consumer surplus on each mango. Thus the total consumer surplus = (20 x 6) / 2 = INR
60 (see example on p.40).

34. The best characterization of a firm that is operating on its long-run average cost curve is when it:

A. experiences constant returns to scale.
B. produces a given output at the least possible cost.
C. chooses a plant size that minimizes the average fixed cost.

Answer: B
“Output and Costs”, Michael Parkin 2009 Modular Level I, Volume 2, pp. 142-143
Study Session 4-17-d
Explain the firm’s production function, its properties of diminishing returns and diminishing marginal product of capital, the relation between short-run and long-run costs, and how economies and diseconomies of scale affect long-run costs.
The long-run average cost curve tells the firm the plant size and the quantity of labor to use at each output to minimize cost. Once the plant size is chosen, the firm operates on the shortrun cost curves that apply to that plant size. Therefore, the firm is said to be operating on its long-run average cost curve when it is producing a given output at the least possible cost.

35. As the quantity of labor increases, which of the following is the most likely outcome with respect to the marginal revenue product (MRP) of labor?

A. MRP increases for a monopoly.
B. MRP decreases for a firm in perfect competition.
C. MRP increases for both monopoly and a firm in perfect competition.

Answer: B
“Markets for Factors of Production”, Michael Parkin 2009 Modular Level I, Volume 2, pp. 255-257
Study Session 5-21-a
Explain why demand for the factors of production is called derived demand, differentiate between marginal revenue and marginal revenue product (MRP), and describe how the MRP determines the demand for labor and the wage rate.
MRP decreases for a firm in perfect competition, due to a decline in marginal product.

36. The cross elasticity of demand for a complementary product would most likely be:

A. zero.
B. positive.
C. negative.

Answer: C
“Elasticity”, Michael Parkin 2009 Modular Level I, Volume 2, pp. 19-20, 27
Study Session 4-13-a
Calculate and interpret the elasticities of demand (price elasticity, cross elasticity, income elasticity) and the elasticity of supply, and discuss the factors that influence each measure.
The cross elasticity of demand is negative for a complement and positive for a substitute.

37. The return to entrepreneurial ability in a firm that makes a positive economic profit is most likely:

A. normal.
B. less than normal.
C. greater than normal.

Answer: C
“Organizing Production”, Michael Parkin 2009 Modular Level I, Volume 2, p. 98
Study Session 4-16-a
Explain the types of opportunity cost and their relation to economic profit, and calculate economic profit.
The return to entrepreneurial ability is greater than normal in a firm that makes a positive economic profit.

38. The belief that money wage rates are sticky is least likely to be associated with:

A. classical macroeconomics.
B. monetarist macroeconomics.
C. Keynesian macroeconomics.

Answer: A
“Aggregate Supply and Aggregate Demand,” Michael Parkin 2009 Modular Level I, Volume 2, pp. 334-337
Study Session 5-23-d
Compare and contrast the classical, Keynesian, and monetarist schools of macroeconomics.
Both Keynesians and monetarists believe that money wage rates are sticky. Classical macroeconomics does not.

39. For a firm in perfect competition, as output increases the marginal revenue will most likely:

A. increase.
B. decrease.
C. remain constant.

40. Price discrimination is most likely an attempt by a monopoly to:

A. resell a product.
B. capture a producer surplus.
C. capture a consumer surplus.

41. Which of the following will most likely lead to cost-push inflation?

A. A decrease in the cost of financing.

39. For a firm in perfect competition, as output increases the marginal revenue will most likely:

A. increase.
B. decrease.
C. remain constant.

Answer: C
“Perfect Competition”, Michael Parkin
2009 Modular Level I, Volume 2, p. 157-158, Figure 3
Study Session 5-18-b
Determine the profit maximizing (loss minimizing) output for a perfectly competitive firm, and explain marginal cost, marginal revenue, and economic profit and loss.
When output increases for a firm in perfect competition, marginal revenue remains constant while marginal cost changes.

40. Price discrimination is most likely an attempt by a monopoly to:

A. resell a product.
B. capture a producer surplus.
C. capture a consumer surplus.

Answer: C
“Monopoly”, Michael Parkin
2009 Modular Level I, Volume 2, pp. 193-195
Study Session 5-19-c, d
Explain price discrimination, and why perfect price discrimination is efficient.
Explain how consumer and producer surplus are redistributed in a monopoly, including the occurrence of deadweight loss and rent seeking.
A monopoly employs price discrimination to capture consumer surplus and to convert a consumer surplus to an economic profit.

41. Which of the following will most likely lead to cost-push inflation?

A. A decrease in the cost of financing.
B. An increase in the money prices of raw materials.
C. A technology change that lowers production costs.

Answer: B
“U.S. Inflation, Unemployment, and Business Cycles” Michael Parkin
2009 Modular Level I, Volume 2, pp, 388-390
Study Session 6-25-b
Describe and distinguish among the factors resulting in demand-pull and cost-push inflation, and describe the evolution of demand-pull and cost-push inflationary processes.
Increased material costs cause firms to manufacture less. Less manufacturing decreases short-run supply making prices rise (see page 388).

43. The monetary policy tools available to the Federal Reserve are least likely to include:

A. open market operations.
B. the ability to determine the required reserve ratios of its member banks.
C. adjustments to the amount of gold held as reserves against Federal Reserve notes.

44. Suppose the CPI basket contains only two goods and services: oranges and haircuts. In the base period, consumers bought 15 oranges at $2 each and 5 haircuts at $10 each. In the current period, consumers buy 15 oranges at $1.75 each and 5 haircuts at $12 each. The CPI for the current period is closest to:

A. 107.81.
B. 114.58.
C. 117.97.

42. Which of the following is least likely to be a tool available to central banks for implementing monetary policy?

A. Inflation targeting.
B. Adjusting taxation.
C. Managing interest rates.

Answer: B
“An Overview of Central Banks” Anne Dolganos Picker
2009 Modular Level I, Volume 2, pp. 477-485
Study Session 6-28-b
Discuss monetary policy and the tools utilized by central banks to carry out monetary policy.
Adjusting taxation is not a tool available to central banks. Only the government can adjust taxation as it is a fiscal policy tool.

43. The monetary policy tools available to the Federal Reserve are least likely to include:

A. open market operations.
B. the ability to determine the required reserve ratios of its member banks.
C. adjustments to the amount of gold held as reserves against Federal Reserve notes.

Answer: C
“Money, the Price Level, and Inflation,” Michael Parkin
2009 Modular Level I, Volume 2, pp. 357-358
Study Session 6-24-d
Explain the goals of the U.S. Federal Reserve (Fed) in conducting monetary policy and how the Fed uses its policy tools to control the quantity of money, and describe the assets and liabilities on the Fed’s balance sheet.
The Fed uses three main policy tools to achieve its objectives: required reserve ratios, discount rate, and open market operations. Making adjustments to gold reserves is not one of the fed policy tools.

44. Suppose the CPI basket contains only two goods and services: oranges and haircuts. In the base period, consumers bought 15 oranges at $2 each and 5 haircuts at $10 each. In the current period, consumers buy 15 oranges at $1.75 each and 5 haircuts at $12 each. The CPI for the current period is closest to:

A. 107.81.
B. 114.58.
C. 117.97.

Answer: A
“Monitoring Jobs and the Price Level,” Michael Parkin
2009 Modular Level I, Volume 2, pp. 305-307, Table 1
Study Session 5-22-d
Explain and calculate the consumer price index (CPI) and the inflation rate, describe the relation between the CPI and the inflation rate, and explain the main sources of CPI bias.
CPI equals 100 times the cost of the CPI basket at current-period prices divided by the cost of the CPI basket at base-period prices. In this problem the current period cost is (15 × 1.75 + 5 × 12) = 86.25. The base period cost is (15 × 2 + 5 × 10) = 80.
The CPI is (86.25 / 80) × 100 = 107.81.
