D

A leftward shift of the short-run aggregate supply curve would illustrate: A) demand-pull inflation B) an inflationary gap C) a positive GDP gap D) cost-push inflation

C

An increase in the incomes of U.S. trading partners would shift in the U.S.: A) aggregate demand curve to the right B) aggregate demand curve to the left C) aggregate supply curve to the right D) aggregate supply curve to the left

D

An increase in the price level will: A) increase net exports B) reduce the value of household debt and increase investment C) increase production costs and reduce short-run investment D) reduce the purchasing power of household wealth and reduce consumption

B

At very low levels of output, the short run aggregate supply curve is relatively A) flat, because firms are reluctant to give their current workers raises when output is so low B) flat, because firms can expand output with relatively little increase in per-unit production cost C) steep, because increasing output will cause relative large increases in per-unit production costs D) steep, because increasing output will cause aggregate demand to increase

C

Higher prices of imported resources will A) move the economy downward and to the right along the aggregate demand curve B) make the aggregate demand curve steeper C) shift the aggregate supply curve to the left D) shift the aggregate demand curve to the left

C

In the short run, a reduction in aggregate demand is: A) likely to cause a reduction in the price level B) unlikely to cause a reduction in the price level because of interest rate effect C) unlikely to cause a reduction in the price level because of menu costs and efficiency wages D) likely to cause a reduction in aggregate supply

1.25

Suppose each input costs $5. What is the per unit production cost at each level of output?

$1.14

Suppose productivity increases by 10% with no change in input prices. Calculate the new per unit production cost.

D

The aggregate demand curve slopes downward to the right: A) because lower domestic price level reduces net exports B) because of the income and substitution effects of lower prices C) at low prices but not at high prices D) because a lower price level reduces the demand for money, which lowers the interest rate and increases desired investment

C

The short run aggregate supply curve: A) assumes that wages and salaries fully match any change in the price level B) is a vertical line located at the full-employment level of output C) shows the amount of real output supplied at various price levels D) becomes increasingly flatter as output expands

What is the productivity level in this economy?
