In this paper we focus on specification of revenue functions in their dual price space. We consider two distance functions, both dual to the revenue function: Shephard output distance function and the directional output distance function, both in price space. The former is multiplicative,...

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.

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...

We exploit the duality between the cost function and the directional distance function in value space to recover hedonic prices of product or asset characteristics. An application is offered for 96 Oregon vineyards located in the Willamette Valley of Oregon that sold between 1995 and 2007....
