Consider the regression model with a single regressor:
Suppose that the assumptions in Key Concept 4.3 are satisfied.
a. Show that X, is a valid instrument. That is, show that Key Concept 12.3 is satisfied with Z i , = X i
b. Show that the IV regression assumptions in Key Concept 12.4 are satisfied with this choice of Z i.
c. Show that the IV estimator constructed using Z i = X j is identical to the OLS estimator.
