Weextend the concept of returns to scale in Data Envelopment Analysis(DEA) to the weight restriction environments. By the additionof weight restrictions, the status of returns to scale, i.e., increasing, constant and decreasing may suffer a change. Wefirst define ``returns to scale'' under...

This paper shows how one can infer the nature of local returns to scale at the input- or output-oriented efficient projection of a technically inefficient input-output bundle, when the input- and output-oriented measures of efficiency differ.

Purpose – Decision making in networks is multilateral and interaction‐based and is often contrasted with unilateral decision making in a hierarchy. The purpose of this paper is to examine whether unilateral interventions can nevertheless be functional in networks. Design/methodology/approach...

Purpose – The main purpose of the present study is to develop appropriate construct to benchmark occupational health and safety performance in industrial setting so that deficiencies can be highlighted and possible strategies can be evolved to improve the performance....

Purpose – The main purpose of the present study is to develop an integrated approach combining data envelopment analysis (DEA) and neural network (NN) for assessment and prediction of performance of Indian B‐schools for effective decision making as error and biasness due to human...

A new approach is supplied for locating efficiency frontiers and evaluating the efficiency of Decision Making Units (DMU's). This is accomplished from observational data by means of an envelopment procedure called DEA (Data Envelopment Analysis) originally developed by Charnes, Cooper and Rhodes...

In this paper we deal with the measurement of technical efficiency (or X-efficiency) of institutions whose operations might be significantly affected by macroeconomic, environmental and non-controllable factors. For this purpose we introduce a four-stage DEA methodology based on the approach...

This paper is aimed at exploring how X-efficiency or management quality is associated with one of the most vivid forms of international banking, that is, entering new markets by setting up foreign subsidiaries. The analysis focuses on the supposition that management quality ought to be one of...

The traditional approach to measuring allocative efficiency is based on input prices, which are rarely known at the firm level. This paper proposes a new approach to measure allocative efficiency which is based on the output-oriented distance to the frontier in a profit – technical efficiency...

This paper shows through the combination of output-orientated data envelopment analysis (DEA) with the calculation of Malmquist indexes that the obvious and persistent differences in growth and levels of per capita income and labour productivity between the German states are less caused by...
