Conflicting Specifications for Investment Functions in Rationing Models: A Reconciliation (*)

Extract

A number of attempts have been made recently (see, a.o., Mulkay [1983], Artus and Muet [1984], Gérard and Vanden Berghe [1984]) to develop and estimate appropriate specifications for investment functions in a rationing context. Some of the specifications proposed are however clearly conflicting, not in the usual sense that they reflect conflicting theoretical premises (between which empirical testing might hopefully discriminate) but in the unacceptable sense that there exists some logical incompatibility between different specifications derived from the same theoretical framework.

In this note, we focus our attention on two specifications among the most significant ones proposed recently, show why they are contradictory and then explain what is the correction to be brought to one of them in order to reconcile both specifications. In the course of the discussion, we also seize the opportunity to point to common empirical practices which are clearly unwarranted and could account for some deceptive results encountered (even with a theoretically correct specification).
