Suppose that Firms A, B, and C are the only polluters in the state and that each emits 4 tons of pollution into the atmosphere. To cut the level of pollution in half, the government mandates system whereby each firm must reduce its pollution level by one-half. The total cost of complying with the mandate is

To calculate the J-statistic you regress the
A) squared values of the TSLS residuals on all exogenous variables and the instruments. The statistic is then the number of observations times the regression R2. B) TSLS residuals on all exogenous variables and the instruments. You then multiply the homoskedasticity-only F-statistic from that regression by the number of instruments. C) OLS residuals from the reduced form on the instruments. The F-statistic from this regression is the J-statistic. D) TSLS residuals on all exogenous variables and the instruments. You then multiply the heteroskedasticity-robust F-statistic from that regression by the number of instruments.
