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 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...
