B) an increase in the real money supply.
C) a fall in the price level.
D) a rise in nominal wages.
2) Assuming money neutrality in the classical model, a 10% increase in the nominal money
supply would cause

B) a 10% decrease in the real money supply.
C) no change in the real money supply.
D) a less-than-10% change in the price level due to a shift in the aggregate supply curve.
3) The idea that expected future increases in output cause increases in the current money supply
and that expected future decreases in output cause decreases in the current money supply, rather
than the other way around, is known as
A) Granger causality.
B) money neutrality.
C) nominal adjustment.
D) reverse causation.
4) Reverse causation is the idea that

B) current increases in the money supply cause future increases in output.
C) expected future increases in the money supply cause increases in current output.
D) expected future increases in output cause increases in the current money supply.
5) The basic classical model can account for the procyclical behavior of money if there
A) are real business cycles caused by productivity shocks.
B) is reverse causation from future output to money.
C) are rational expectations among the public.
D) are propagation mechanisms in the economy.
6) Friedman and Schwarz argue that money is not neutral because
A) theoretical models of the economy don't show monetary neutrality.
B) money is a leading, procyclical variable.
C) they found several historical incidents in which changes in the money supply were not
responses to macroeconomic conditions, and output moved in the same direction as money.
D) they found no evidence that productivity changes or changes in government spending
contributed to business cycles; only monetary changes preceded every recession.
7) You and a friend are arguing over the issue of the nonneutrality of money. You believe that
money is not neutral, and to prove your point you would cite all of the following EXCEPT
A) large gold discoveries that increased the money supply preceded an economic boom.
B) a change in monetary institutions preceded a boom or recession.
C) a change in the leadership of the Fed and its policy was followed by noticeable changes in the
money supply and a recession or inflation.
D) the fact that every recession was preceded by a drop in the money supply.
8) Why do many economists believe that money affects output? What is the empirical evidence
in support of that belief?
9) A classical economy is described by the following equations:
Cd = 500 + 0.5(Y - T) - 100r.
Id = 350 - 100r.
L = 0.5Y - 200i.
= 1850.
πe = 0.05.
Government spending and taxes are equal where T = G = 200. The nominal money supply M =
3560.
(a) What are the equilibrium values of the real interest rate, the price level, consumption, and
investment?
(b) Suppose an economic shock increases desired investment by 10, so it is now Id = 360 - 100r.
How does this affect the equilibrium values of the real interest rate, the price level, consumption,
and investment?
(c) Returning to the initial situation in part (a), suppose an economic shock increases desired
consumption by 10, so it is now Cd = 510 + 0.5 (Y - T) - 100r. How does this affect the
equilibrium values of the real interest rate, the price level, consumption, and investment?
10) Suppose the money demand of individuals and firms depends on what they perceive to be the
probabilities that the economy will expand or contract over the following six months. Suppose
their money demand is given by the equation L = 0.5Y - 100i + 20z, where z is the probability
that the economy is expanding six months in the future. If z = 1, the economy will certainly be in
recovery, if z = 0, the economy will certainly be in recession, and for z between 0 and 1 there is
some uncertainty about the future state of the economy. Use a classical (RBC) model of the
economy. If the Fed moves the money supply to target the price level, how does the money
supply relate to the expected future state of the economy? Is this an example of reverse
causation?
