This paper empirically investigates the implications of the choice of dates when imposing local restrictions to maintain convexity in output prices and concavity in factor endowments in the the estimation of a GNP function approximated by a translog (TL) function. Using macroeconomic data for Switzerland, we compare the TL to a symmetric normalized quadratic (SNQ) function on which global curvature restrictions can be imposed. When both functions are unrestricted for curvature, convexity in… Expand
