An inconsistency is found in the demand side of the NEG models developed in Pflüger (2004) that follows from the absence of a non-negativity constraint on the consumption of agricultural goods. This seriously weakens the results of the original paper and those of ensuing contributions in Pflüger and Südekum (2008a,b). A solution to this problem is developed which imposes severe restrictions on the relative size of two of the core model parameters, the implications of which are examined.
