1. The classical principle of monetary neutrality states that changes in the money supply do not influence _________ variables, and it is thought most applicable in the _________ run.
a. nominal; short
b. nominal; long
c. real; short
d. real; long
Answer explanation
The monetary neutrality principle suggests that changes in the money supply affect only nominal variables (e.g., price level, wages, and exchange rates), but not real variables (e.g., real GDP, employment, and real wages) in the long run.
In the short run, monetary policy can influence real output due to price and wage rigidities, but in the long run, these effects fade, and only nominal prices adjust.

7. If an economy always has inflation of 10 percent per year, which of the following costs of inflation will it NOT suffer?
a. shoeleather costs from reduced holdings of money
b. menu costs from more frequent price adjustment
c. distortions from the taxation of nominal capital gains
d. arbitrary redistributions between debtors and creditors
Answer explanation
Predictable inflation (like a stable 10% per year) allows businesses, lenders, and borrowers to adjust expectations when setting interest rates and wages.
Arbitrary redistributions between debtors and creditors occur when inflation is unexpected, because loans are typically agreed upon in nominal terms.
