Relations between convexity and homogeneity in multioutput technologies
Much research has been done on the economic concept of convexity. P. Newman's findings that a firm may produce more than one output can be applied to the study of multioutput production. Research on the relationship between convexity and homogeneity shows that Newman's theories are applicable to multiproduct technologies in a set-theoretic approach. Moreover, convex individual technology sets can be made from aggregate technology.

Exports and labor demand: Searching for functional structure in multi-output multi-skill technologies
A production unit's technology must satisfy some restrictive conditions to simplify the representation of a technological relationship between inputs and outputs. New results for aggregating labor inputs and outputs in terms of restrictions on elasticities of scale and substitution is presented.

A non-tested test of separability for flexible functional forms
The Flexible and Separable Translog model is presented as a better separable structure than forms derived through parametrically restricting a translog model. It is also shown that separability tests can be cast in a non-tested framework.
