a. What is the expected relationship between CM and each of the other variables?

b. Regress CM on FLR and present the usual estimation results.

c. Regress CM on FLR and PGNP and present the usual estimation results.

d. Regress CM on FLR, PGNP and TFR and present the usual estimation results.

e. Given the various regression results, which model would you choose and why?

f. If the regression model in (d) is the correct model, but you estimated (a) or (b) or (c), what are the consequences?

g. Suppose you have regressed CM on FLR as in (b). How would you decide if it is worth adding the variables PGNP and TFR to the model? Which test would you choose. Perform the test and present your conclusion.
