Then, using existing research on “best existing case” scenarios of the ecological impact of different foods, I estimate the land usage and gr...

Necessary and sufficient conditions for Identlflability with linear coefficient and covarlance restrictions are developed. In practical terms, covarlance restrictions aid identification if and only if they imply either that (1) a set of endogenous variables is predetermined in a particular equation (generalizing the notion of recursiveness) or (11) an identifiable residual is predetermined in a...
