QUESTION 8 Having many relevant instruments: a. is good because they provide more information. b. is a problem because instead of being just identified, the regression now becomes overidentified. С. typically results in larger standard errors for the TSLS estimator. d. is not as important for inference as having the same number of endogenous variables as instruments. е. All of the above. O f. None of the above.

1. You are interested the causal effect of X on Y, B1. Suppose that X, and X2 are uncorrelated. You estimate B1 by regressing Y onto X1 (so that X2 is not included in the regression).

Omitted variable bias violates which of the following assumptions: (a) The conditional distribution of u, given X1i X2i, ...Xki has a mean of zero (b) (Xi, X2i...Y;), i = 1, ., n are independently and identically distributed (c) Heteroskedasticity (d) Perfect multicollinearity
