Question 2 (20 marks) High and rising inflation has forced governments to increase interest rates. These increases are contractionary policies. You collected data based on theory and estimated the following model below:
log GDP =6.2-0.4r-0.02\pi -0.04UE
(.012)(.643)(.981)
n=40,R^(2)=0.81
where, GDP is Gross Domestic Product,
\pi
is the inflation rate, r is the interest rate, UE is the unemployment rate, standard errors are in parentheses. a) Interpret each of the regression above. Are the signs what
u
expect based on theory? (6 marks) b) All other factors being equal, test the hypothesis that a change in interest rate cause a
0.5%
decline in GDP, what do you conclude? (7 marks) c) All other factors being equal, test the hypothesis that an increase in the unemployment reduces GDP by
.05%
