Short Answer Question
78. What are the determinants of the potential output for an economy?
79. Use the equation of exchange to show that in the long run, inflation must equal money

level, and government purchases increase, describe what happens in terms of the long-run real
interest rate, and why, to keep the economy at its potential output level.
87. Given a central bank's monetary policy reaction curve, if inflation increases by 1% why
would policymakers likely have to increase the nominal interest rate by more than the increase in
the expected rate of inflation?
88. Discuss what happens to the monetary policy reaction curve if the Fed were to lower their
inflation target and why?
89. Is the monetary policy reaction curve applicable only to central banks that have an explicit
inflation target? Explain.

Essay Questions
102. Discuss why many economists maintain that continued deficit spending by government is
likely to "crowd out" (decrease) investment spending in the long run.
103. Former Bank of England Governor Mervyn King, commenting on a speech given by then
Fed Chairman Greenspan, said "any (coherent) monetary policy can be written as an inflation
target plus a response to supply shocks." What do these comments mean and what insight do
they provide us to the focus of central banks?

have any long-run real effects. What lies behind this argument?
105. At the conclusion of its meeting on January 27, 2016, the Federal Open Market Committee
released a statement that included the following sentence: “Given the economic outlook, the

labor market conditions and return to 2 percent inflation.” What is the significance of this
statement?
