This paper estimated cost inefficiency, scale and scope measures and cost productivity growth rates of banks in United Arab Emirates during 1998 (a bad year for banks due to lower oil price) and 2000 ( a good year for banks as the oil prices were higher). The study provided evidence that:...

We work out technical efficiency levels of the Indian States and Union Territories using Data Envelopment Analysis from 1980-81 to 1997-98. We decompose net value added per worker growth into components attributable to technological changes (shifts in the overall production...

This paper offers a review of investment performance appraisal methods. The review starts with an exhaustive coverage of various methods ranging from early measures of risk-adjusted return to more recent methods including the rating given by ASSIRT, a financial services organisation that assess...

We offer an efficiency-based approach to derive market partitions and respective benchmarks using Data Envelopment Analysis. Product efficiency is measured as an output to input value from the customer’s perspective. Products offering a maximum customer value relative to alternatives represent...

In this paper we tackle the problem of the presence of negative average rate of returns in the computation of the performance of ethical mutual funds. The presence of these negative values raises problems both in the computation of the classical performance indicators and in DEA modeling. In...

We work out technical efficiency levels of 29 countries consisting of some selected South Asian, East Asian and EU countries using data envelopment analysis. Luxembourg has an efficiency score of one(most efficient) in all the years .Netherlands also has an efficiency score of one in...

This paper estimates commercial banks’ efficiency in three relatively homogenous groups of countries with different level of economic development and different involvement in the process of European integration. The first group consists of Portugal and Greece, the second group is represented...

The Law of One Price (LoOP) states that all firms face the same prices for their inputs and outputs in the competitive market equilibrium. This law has powerful implications for productive efficiency analysis, which have remained unexploited thus far. This paper shows how LoOP-based weight...

We discuss the nonparametric approach to profit efficiency analysis at the firm and industry levels in the absence of complete price information, and propose two new insights. First, choosing one commodity (whose price is known) as a numeraire good enables us to measure profit inefficiency in...

Data Envelopment Analysis (DEA) is a linear programming based method for evaluating performance of comparable production units such as firms. Although the method is already extensively applied in many areas of economics, its use in environmental economics and related fields remains limited. The...
