Chapter 16 – Interest Rates and Monetary Policy
16–33
40. Other things being equal, what effect will each of the following have on the equilibrium rate of interest?
(a) an increase in the supply of money; (b) an increase in the equilibrium level of national income; (c) a
decrease in the supply of money; (d) a leftward shift of the asset demand for money.
41. Use the below graphs to answer the following questions assuming the nominal GDP in the economy is
given.
(a) Look at graph A and suppose the supply of money increases from 100 to 200. What will be the
equilibrium rate of interest?
(b) Look at graph B which shows an investment-demand curve for this economy. Given the answer to part
(a) above, how much will investors plan to spend on capital goods?
(c) What will happen to aggregate demand?
(d) Now trace what will happen in parts (a)–(c) if the money supply increases to $300.
42. Trace the cause-effect chain that results from an expansionary monetary policy.
An expansionary monetary policy will cause bank reserves to grow and the money supply to expand.
Interest rates will fall and this encourages investment spending. Real GDP will rise by a multiple of the
increase in investment. [text: E p. 687; MA p. 331]
