In the Case of Heterogeneous Causal Effects,the Following Is Not

question 2

Multiple Choice

In the case of heterogeneous causal effects,the following is not true:

• A)in the circumstances in which OLS would normally be consistent (when E(ui Xi)= 0),the OLS estimator continues to be consistent.
• B)OLS estimation using heteroskedasticity-robust standard errors is identical to TSLS.
• C)the OLS estimator is properly interpreted as a consistent estimator of the average causal effect in the population being studied.
• D)the TSLS estimator in general is not a consistent estimator of the average causal effect if an individual's decision to receive treatment depends on the effectiveness of the treatment for that individual.
