C) ex ante real interest rate.
D) ex post real interest rate.
In the relationship expressed in functional form, Y = G(K, L), Y stands for real GDP, K
stands for the amount of capital in the economy, and L stands for the amount of labor in
the economy. In this case G( ):
A) is the growth rate of real GDP when the amount of capital and labor in the economy
is fixed.
B) indicates that the variables inside the parentheses are endogenous variables in the
model.
C) is the symbol that stands for government input into the production process.
D) is the function telling how the variables in the parentheses determine real GDP.
Assume that an economy is governed by the Phillips curve p = pe ” 0.5(u ” 0.06), where
p = (P ” P“1)/P“1, pe = (pe ” P“1)/P“1, and 0.06 is the natural rate of unemployment.
Further assume pe = p“1. Suppose that, in period zero, p = 0.03 and pe = 0.03that is, that
the economy is experiencing steady inflation at a 3-percent rate.
a. Now assume that the government decides to impose whatever demand is necessary to
cut unemployment to 0.04. Suppose the government follows this policy for periods 1
