Typical econometric production practices under duality ignore the source of disturbances. We show that, depending on the source, a different approach to estimation is required. The typical approach applies under errors in factor input measurement rather than errors in optimization. An approach...

"Numéraire" prices that are measured with error create challenges for econometric estimation. A straightforward approach for a model with linear input demands, such as generated from a quadratic normalized profit function, is proposed where the "numéraire" price is measured with error....

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...

Standard definitions of the cost function do not admit risk. Standard (ex post) approaches to cost function estimation yield biased and inconsistent estimates when production is stochastic. Recently an (ex ante) approach to cost function estimation with stochastic production has been developed...

Supply functions in the ubiquitous Gorman class are examined for their homogeneity properties. Homogeneity places surprisingly strong restrictions on functional forms. These forms facilitate testing of aggregability given homogeneity or homogeneity given aggregability or testing both. Copyright...

Duality methods for incomplete systems of consumer demand equations are adapted to the dual structure of variable cost functions in joint production. This allows identification of necessary and sufficient restrictions on technology and cost so that conditional factor demands can be written as...
