Need help with Question 4!

Mankiw, Romer, and Weil (1992) Replication Extra Credit Answers should be TYPED in a separate document. This document will be turned-in on Blackboard on Friday April 2nd. In this extra credit assignment, worth a total of 25 points, you will work to replicate the results of Mankiw, Romer, and Weil (1992). 1. (5 Points). Read Mankiw, Romer, and Weil (1992). In two paragraphs or less summarize the main question, the data, and the results. 2. (10 Points). Using GRETL and the dataset titled "MRW on Blackboard, replicate as much of Table I and Table II as you can. To do this you will need to regress the log of per-capita income on the variables specified by Equation 7 (Table I) and Equation 11 (Table II). Explain the proxy variable used by Mankiw, Romer, and Weil (1992) to measure the rate of human capital accumulation (sn). How does adding human capital accumulation change results of the model? That is, why are Table I and Table II different? Why do Mankiw, Romer, and Weil (1992) think this difference is important? 3. (5 Points). Using GRETL and the dataset titled "MRW on Blackboard, replicate Figure 1. 4. (5 Points). Summarize the discussion in Section IV of the paper. Does the Solow model adequately explain real interest rate differentials across countries? Why or why not?
