The Malmquist productivity index studies productivity change, that is, the technical progress or regress together with the efficiency changes over time. In a nonparametric framework, the index can be estimated by data envelopment analysis (DEA). In this paper, first all inputs are divided into...

Utilizing recent developments in data envelopment analysis (DEA), this paper examines the performance of the top 55 U.S. commercial banks via a two-stage production process that separates profitability and marketability. Substantial performance inefficiency is uncovered in both dimensions....

O presente artigo tem como objetivo estimar, através da metodologia DEA (Análise Envoltória de Dados), as eficiências geradas pelas empresas do setor frigorífico de carne bovina, e verificar se a realização de fusão, a fim de obter economias de escala, pode sempre implicar em...

In this paper we use a two stage procedure, based on bias corrected DEA, to evaluate the impacts of regulatory reforms on technical efficiency of 28 Italian airports during the period 2000–2006. We employ two different DEA models: physical and monetary. The first relies on the aeronautical...

The paper analyses the nature of the achievement possibility frontier between research and teaching quality in higher education under a system of quality evaluation by reference to discrete quality grades. It finds several important reasons why the associated feasible set is likely to be...

Efficiency scores of the National Innovation System (NIS) for 22 countries, including the BRICS, G7, are calculated with the Data Envelopment Analysis (DEA). Relevant factors that may affect the innovation system efficiency are summarized based on the NIS Approach and the New Growth Theory....

Using the non parametric approach of Data Envelopment Analysis (DEA) this paper examines firm’s heterogeneity in the Indian pharmaceutical industry by measuring their input and output efficiencies for the period 1991 to 2005. The analysis establishes that even though firms have been able to...

This study computes and analyzes the total-factor energy efficiency (TFEE) of 11 industries in 14 developed countries during the period of 1995-2005 using the data envelopment analysis (DEA) approach. There are four inputs: labor, capital stock, intermediate inputs other than energy, and energy....
