E6.2 Using the data set Growth described in Empirical Exercise E4.1, but excluding the data for Malta, carry out the following exercises.

a. Construct a table that shows the sample mean, standard deviation, and minimum and maximum values for the series Growth, Trade-

Share, YearsSchool, Oil, Rev_Coups, Assassinations, and RGDP60.

Include the appropriate units for all entries.

b. Run a regression of Growth on TradeShare, YearsSchool, Rev_Coups, Assassinations, and RGDP60. What is the value of the coefficient on Rev_Coups? Interpret the value of this coefficient. Is it large or small in a real-world sense?

c. Use the regression to predict the average annual growth rate for a country that has average values for all regressors.

d. Repeat

(c) but now assume that the country’s value for TradeShare is one standard deviation above the mean.

e. Why is Oil omitted from the regression? What would happen if it were included?
