Problem 2. Consider TSLS estimation with a single included endogenous variable and a single instrument. Then the predicted value from the first-stage regression is X₂ = 0 + 1 Zi. (i) Use the definition of the sample variance and covariance to show that sxy = 1szy and X = is the OLS estimator of (ii) Remember that 1 sxz/s2 and that the TSLS estimator the slope parameter in the regression of Y on X. Use these facts and the result of part (i) to prove that TSLS obtained by the two-stage least squares procedure can be written as TSLS TSLS SZY SZX
