A Strong Test of the Von Liebig Hypothesis
Posted: 1 Oct 2001
An implication of the von Liebig hypothesis is that crop-production functions have right-angle isoquants. This article presents a nonparametric estimation of right-angle isoquant production functions. It then describes a new test for right-angle isoquants. The procedures are used to test experimental data on corn and wheat.
