This paper develops two cost decompositions based on the multiplicative and additive Russell efficiency measurement framework. While the multiplicative cost decomposition is a straightforward extension of the standard cost decomposition, the decomposition we develop in this paper incorporates...

This paper develops a slack-based decomposition of profit efficiency based on a direc- tional distance function. It complements Cooper, Pastor, Aparicio and Borras (2011).

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...

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...

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

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 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.
