Extract

Multicollinearity and a lack of degrees of freedom are problems in simultaneous systems, particularly in large models where the number of predetermined variables may exceed the number of observations. Such problems are somewhat less obvious in the small and medium-sized models typically estimated by agricultural economists. Thus, estimators designed to cope with the degrees of freedom (undersized sample) problem have received little attention in agricultural economics applications relative to macroeconometric uses.
