WOLAK* Stanford Received lJniversi[v‚ February Stunford‚ CA 94305‚ tiSA 1986‚ final version received July 1988 This paper develops three asymptotically equivalent tests for examining the validity of imposing linear inequality restrictions on the parameters of linear econometric models. First we consider the model .v = X/3 + e. where r is N(O‚8)‚ and the
