With the advent of tradable permit programs for bad outputs (e.g., SO2 emissions); concerns arose over whether the theoretical gains from trade would be realized. We will employ a methodology that calculates the potential gains accruing to coal-fired electric power plants from implementing a...

The objective of this research was the development of a method that integrated an activity analysis model of profits from production with a biophysical model, and included the capacity for optimization over multiple objectives. We specified a hybrid genetic algorithm using activity analysis as a...

Econometric estimation of allocative and technical efficiency has frequently been carried out using a shadow cost function and its associated share or demand equations. Since the problem is formulated in terms of shadow prices, the effect of allocative inefficiency on input usage must be...

This article provides a method of measuring performance in the public sector, specifically performance of school districts. The technique is closely related to the family of Farrell type efficiency measures as well as data envelopment analysis (DEA). It also can be viewed as a generalization of...

The directional distance function provides a complete characterization of the production technology and, when differentiable, can be used to derive shadow prices for nonmarket outputs. A quadratic functional form and the linear programming least absolute deviations method is used to implement...

In this paper, a dynamic network DEA model is developed to evaluate the potential gains in final output from a merger of two firms. The two firms are allowed to have different production technologies or share a common technology. In a beginning period each firm uses period specific inputs to...

Presents an elementary version of the Malmquist productivity change index. This index measures productivity change using data on inputs and outputs, but does not require price information.
