WebJun 24, 2015 · 1 Answer. Generally, price is endogenous in this set of simultaneous equations. One strategy we can use to overcome the bias is to find a valid instrument for price—call it Z. We’d need something that satisfies C o v ( P, Z) ≠ 0 and C o v ( Z, μ 1) = 0. The trouble with simultaneous equations is that upon observing some ( P, Q) pair, all ... WebNote that in reality, the Hausman test in IV estimation has as its null hypothesis that both the OLS and the IVE estimator are consistent. If the null is rejected, it only tells us that at least one of the two is inconsistent.
