We show under very parsimonious assumptions that FGLS and GLS are asymptotically equivalent when errors follow an invertible MA(1) process. Although the linear regression model with MA errors has been studied for many ...

informationally-demanding way to ensure efficient make-or-buy decisions is to price inputs at marginal cost. The extent to which input prices can depart from marginal cost while still inducing efficient make-or-buy decisions depends on the relative efficiency...

Input price and novel vertical control regulations are derived for a vertically integrated upstream monopolist when the monopolist can engage in non-price discrimination against a downstream rival. The paper extends the literature on sabotage...
