| The current food crisis all over the globe has necessitated alternative policy actions by various stakeholders in almost all countries of the world. Consequently, efforts are focused on increased investment in agricultural research and development. The study evaluates impact of technological innovations on estimates of technical, allocative and cost efficiency from a parametric stochastic and non-parametric distance functions. Inefficiency effects are modelled in a second stage endogeniety-corrected Tobit regression model as a function of technological innovation and other policy variables. The results from both approaches show there is substantial technical, allocative and cost inefficiency in maize production and that analysis of technical, allocative... |

| This study aims to characterise the evolution of vineyard production, to measure the levels of technical efficiency, and to relate these with farmers and farms attributes. The sample used is composed of a panel of vineyard farms, for the period 2000-2005, belonging to Portuguese Alentejo region. The methodology used to estimate technical efficiency, was the stochastic production frontier. The results showed that there are room to improve the levels of technical efficiency in input use and that efficiency is variant with time. It was observed that technical efficiency increases with economic size and net farm income, as well as with family entrepreneurship. |

| Economic reform in the Central and Eastern European countries in the 1980s helped transform the structure and volume of agricultural production, consumption and trade, and resulted in significant agricultural productivity improvements. However, there are large differences among the transition countries in the magnitude and direction of these changes. The main objective of this study is to measure and compare the levels and trends in agricultural productivity in transition countries with those of the European Union (EU) countries making use of the most recent data available from the Food and Agriculture Organization (FAO). This study employs a parametric distance function approach to measure Malmquist productivity index as well as the magnitude and... |
