Question 3 - Policy Analysis
Use the data in INJURY.DTA for this exercise.
1) Using the data for Kentucky, reestimate equation (13.12) in the book, adding as explanatory variables male, married, and a full set of industry and injury type dummy variables. Interpret the estimated coefficient for af chnge , highearn and af chnge highearn variables. What do your results imply about the impact of policy?
2) What do you think about the small R-squared from part (1)? Does this mean the equation is useless?
3) Estimate equation (13.12) using the data for Michigan. Compare the estimates on the interaction term for Michigan and Kentucky. Is the Michigan estimate statistically significant? How do you explain the different results (in terms of significance) for Kentucky and Michigan?
