A $9.6 trillion

Refer to the accompanying figure. In the figure, which interval represents a business cycle expansion? A A to B B B to C C A to C D B to D

The following data give the dates of successive turning points in U.S. economic activity and the corresponding levels of real GDP at the time. Which of the turning points are troughs? A (A), (B), and (C) B (C), (D), and (E) C (A), (C), and (E) D (B) and (D)

In Macroland, potential output equals $100 trillion and the natural rate of unemployment is 4 percent. If the actual unemployment rate is 3 percent, then the output gap equals: A −1 percent. B −2 percent. C 1 percent. D 2 percent.

D 2 percent.

Using Okun's Law, fill in the missing data in the table below. All data re hypothetical.

For each year apply the formula for Okun's Law: [(Y - Y-star)/Y-star] x 100 = -2 (U - U-star) Calculating (a): [(7,840 - 8,000)/8000] × 100 = -2(6 - a). Therefore, a = 5% Similarly, you can calculate that b = $8,100 billion c = $8,282 billion, and, d = 4%

How is each of the following likely to be affected by a recession: the natural rate of unemployment, the cyclical unemployment rate, the inflation rate, and, the poll ratings of the President?

The natural unemployment rate is the sum of structural and frictional unemployment and excludes cyclical unemployment. Hence, the natural unemployment rate by definition should not be affected by a recession. Also, by definition, the cyclical unemployment rate rises in a recession. Inflation tends to decline in the period following a recession. Finally, poll ratings of presidents tend to be strongly correlated with the state of the economy, so a recession will probably reduce a president's popularity.

According to Okun's Law, when cyclical unemployment increases from 1 to 2 percent, the output gap increases from ___ percent. A -2 to -4 B -1 to -2 C 3 to 4 D 1 to 2

A -2 to -4

Which firm is likely to see its profits reduced the most in a recession: an automobile producer, a manufacturer of boots and shoes, or a janitorial service? Which is likely to see its profits reduced the least? Explain.

In general, producers of durable goods are affected most by recessions while producers of non-durables (like food) and services are affected least. Automobiles are durable goods, so the automobile producer would probably see its profits reduced the most, while the janitorial service will see the smallest decline in profit. Boots and shoes are "semi-durable" since a pair of shoes may last for several years and people can put off purchases of these for a while if necessary. Thus the boot manufacturer's losses are likely to fall in between those of the other two firms.
