In response to a question raised by Knox Lovell, we develop a method for estimating directional output distance functions with endogenously determined direction vectors based on exogenous normalization constraints. This is reminiscent of the Russell measure proposed by Färe and Lovell (J Econ...

We analyse a sample of airline firms most recently examined by Alam and Sickles (2000) and extended by Good, Sickles and Weiher (2005) to include an index of circuity as one of our measures of service quality of airline travel. An additional measure of quality of airline travel is timeliness and...

In this paper we analyze resource allocation distinguishing between the decision of when to begin allocation and over how many periods to apply the resources. We present analytical results for specific production technologies under different returns to scale assumptions, under capacity...

The purpose of this paper is to apply a generalized version of the Farrell measure of technical efficiency to a sample of Illinois strip mines. We disaggregate the original Farrell measure (which was designed to measure lost output or wasted inputs due to underutilization of inputs) into three...

In this paper we introduce a piecewise parametric production model that may be used as a reference technology for efficiency gauging. We show that other piecewise reference technologies used in efficiency measuring are obtained as special cases of our model.

In this paper we report on our initial approach to introduce technical change into a DEA model endogenously, through optimization.

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...
