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...

This paper studies the performance of nineteen private commercial banks and two government-owned banks in Bangladesh during the period 2005–2008 using a slacks-based inefficiency measure and the directional technology distance function. Performance is measured assuming a black-box production...

The directional output distance function (Chambers, Chung, & Färe, 1996) is used to construct a Malmquist-Luenberger index of total factor productivity growth for manufacturing when both good and bad outputs are jointly produced. The index is constructed using information on good and bad output...

In recent years, economists have started to move beyond calculating regulatory effects on a pollutant-by-pollutant basis since their interaction is important. In this study, we take up this issue. To allow for joint production of multiple pollutants and marketable output, we specify our...

Using data on the manufacturing sector for the 50 states during 1977-1996, we decompose labor productivity growth into changes due to enhanced efficiency, capital accumulation, and technological progress. We find some evidence that labor productivity is converging among the 50 states, although...

The knowledge production process of thirty universities that participated in nanobiotechnology research during 1990--2005 is estimated by a stochastic directional technology distance function. Knowledge outputs include journal articles, patents, and Ph.D students. The dual elasticity of...

In this paper we estimate the total factor productivity of UK airports using a Malmquist index. Productivity change is factored into an index of efficiency change and an index of technological change. Technological change is further decomposed into indexes that measure the bias in the production...
