An economist wishes to study the impact certain variables have on real GDP along with determining whether politics has any impact. A multiple regression is done where real GDP is the dependent variable and we have the following explanatory variables: M1 = M1 money supply CPI = Consumer Price Index TREND = trend variable (1, 2, 3,...) PRES= = a dummy variable that equals 1 for when a Democrat is President and O when a Republican is President. For the multiple regression provided below, answer the following questions: a. What is the multiple regression equation? b. Is this a good or bad model? Explain. Use a 0.05 level of significance. c. Using a 0.05 level of significance, which variables are important in explaining real GDP? d. Does it matter what party controls the Presidency with regard to real GDP? Explain. d. Does it matter what party controls the Presidency with regard to real GDP? Explain.
