Assume that the demand for real money balance (M/P) is M/P = 0.6Y ” 100i, where Y is
national income and i is the nominal interest rate (in percent). The real interest rate r is
fixed at 3 percent by the investment and saving functions. The expected inflation rate
equals the rate of nominal money growth.
a. If Y is 1,000, M is 100, and the growth rate of nominal money is 1 percent, what must
i and P be?
b. If Y is 1,000, M is 100, and the growth rate of nominal money is 2 percent, what must
i and P be?
Consider the impact of an increase in thriftiness in the Keynesian-cross analysis.
Assume that the marginal propensity to consume is unchanged, but the intercept of the
consumption function is made smaller so that at every income level saving is greater.
This will:
A) lower equilibrium income by the decrease in the intercept multiplied by the
multiplier.
B) lower equilibrium income by the decrease in the intercept.
C) raise equilibrium income by the decrease in the intercept.
D) raise equilibrium income by the decrease in the intercept multiplied by the
multiplier.
