Abstract

Dual production specifications derived under certainty are typically randomized for econometric purposes with ad hoc error specifications. This article shows that such approaches can cause integrability conditionsto fail. In particular, if errorsin input demands represent errorsin optimization that affect output, then typical dual approachesdo not yield congruent suppliesand demands.
