Simar and Wilson (J. Econometrics, 2007) provided a statistical model that can rationalize two-stage estimation of technical efficiency in nonparametric settings. Two-stage estimation has been widely used, but requires a strong assumption: the second-stage environmental variables cannot affect...

This study investigates the causes of declining output performance in the Ghanaian fruit pro-duction industry. Average industrial output level is lagging far behind that of competing na-tions (for instance, the productivity of Ghana pineapple farms is 60 T/Ha compared to 120 T/Ha for Cost Rica...

One hears that the credit ranking score has increased technical efficiency in financial holding companies, when a data envelopment analysis (DEA) is employed. Our empirical results show that the credit ranking scores will obviously affect the estimated results of efficiency measurement in...

Sardinia (Italy) is one of the most important European regions for sheep dairy and sheep milk cheese production. However the Sardinian sheep dairy industry is currently going through a dramatic crisis, and verifying whether it can recover part of its profitability is now a priority. Attention is...

The study investigated the resource use efficiency among Fadama crop soko (Celosia argentea), watermelon (Critullus lanatus), and maize (zea mays) farmers in Ibadan/Ibarapa agricultural zone of Oyo state, Nigeria. Data were collected from 120 respondents who were randomly selected and...

Background: Eritrean gross national income of Int$610 per capita is lower than the average for Africa (Int$1620) and considerably lower than the global average (Int$6977). It is therefore imperative that the country’s resources, including those specifically allocated to the health sector, are...

Following the using a panel of 402 commercial banks from 15 developing countries over the period between 2000-2003 period, we assess the effect of bank size on technical efficiency and its two components: pure technical and scale efficiencies. We use in this study data envelopment approach (DEA)...
