5) If an increase in aggregate demand is greater than expected, actual inflation is:
A) less than expected inflation and unemployment decreases.
B) greater than expected inflation and unemployment increases.
C) greater than expected inflation and unemployment decreases.
Answer C
Reasoning Greater than expected increase in aggregate demand suggests that actual inflation will exceed expected inflation and unemployment will decrease.
Look at it this way…., aggregate demand is more than expected, prices will increase causing more inflation and decrease in unemployment. Look at the Phillips curve and you should see it clearly.
6) In a discussion about the factors that determine a firm’s demand of labor, Kathleen Jorgensen asserts the following:
Statement 1: A firm’s marginal revenue curve is equivalent to its shortterm demand curve.
Statement 2: A decrease in the equilibrium market price of a firm’s product will increase the firm’s demand for labor because the firm will sell more units of the product.
Statement 1 Statement 2
A) Correct Incorrect
B) Correct Correct
C) Incorrect Incorrect
Answer C
Reasoning The marginal revenue product of labor (MRP) curve defines a firm’s shortrun labor demand curve. MRP is the gain in total revenue from selling the additional output from employing one more unit of labor. A decrease in the equilibrium market price of a good reduces the MRP of the labor used to produce that good. The result is a decrease in the firm’s demand for labor. |
