2 INSTRUCTIONS In each question there is only one correct answer. Select the answer you believe to be most correct. Each correct answer is worth 2.5 points. 1. Which of the following equations is correct? a. Labor force = number of employed. b. Labor force = population - number of unemployed. c. Unemployment Rate = (number of unemployed adult population) x 100. d. Unemployment Rate = (number of unemployed labor force) x Robin lives on a deserted island. If she spends 8 hours fishing, she catches 24 fish. Her productivity of fishing is a. 192 fish. b. 1/3 hour per fish. c. 3 fish per hour. d. The answer cannot be computed using the information provided. 3. The labor-force participation rate is defined as follows: a. (Labor Force Adult Population) x 100. b. (Adult Population Labor Force) x 100. c. (Employed Adult Population) x 100. d. (Employed Labor Force) x The BLS recently reported that there were million people over age 16 who had at least a bachelor s degree. Of this number million were in the labor force and were employed. What was the labor-force participation rate and the unemployment rate for this group? a. about 98 percent and 1.49 percent b. about 80 percent and 1.85 percent c. about 79 percent and 1.89 percent d. None of the above is correct. 5. Rick loses his job and immediately begins looking for another. Ceteris paribus, a. the unemployment rate is unaffected, and the labor-force participation rate increases. b. the unemployment rate decreases, and the labor-force participation rate is unaffected. c. the unemployment rate increases, and the labor-force participation rate decreases. d. the unemployment rate increases, and the labor-force participation rate is unaffected.

3 6. The local Chevrolet dealership has an increase in inventory of 22 cars in In 2001 it sells all 22 cars. a. The value of the increased inventory will be counted as part of GDP in 2000, but the value of the 22 cars sold in 2001 will not cause 2001 GDP to increase. b.

Unmeasured quality change is a problem in the CPI because a. if the quality of a good deteriorates, the purchasing power of a dollar decreases even if the price of the good remains the same. b. the Bureau of Labor statistics does not attempt to account for quality changes that affect the standard of living. c. if the quality of a good improves, the purchasing power of a dollar increases even if the price of the good remains the same. d. a and c 14.
