| This paper analyses efficiency and total factor productivity (TFP) in Hungarian sugar beet production applying non-parametric frontier techniques. For 2004 and 2005 efficiency and TFP are calculated by Data Envelopment Analysis (DEA) and by a Malmquist index respectively. Between 2004 and 2005 the average technical efficiency was very stable, around 0.80 for CRS efficiency and 0.87 for VRS efficiency, suggesting that in both years farms were similarly clustered towards the frontier. The analysis of returns to scale reveals that during both years half (48%) of the sugar beet growers were operating under increasing returns to scale. In the two analysed years changes occurred between decreasing returns to scale and scale efficient farms, when the first... |

| The abolishment of the dairy quota system in the EU is expected to increase competition across dairy farms in Europe. Assuming a common price for milk in the EU, only the most efficient farms will survive in the new environment. The main objective of the paper is to compare dairy farms in Germany, The Netherlands and Hungary about their technical efficiency. In the first part of the research, the efficiency is measured by partial efficiency indexes using one dimensional efficiency measuring. In the second part, the Data Envelopment Analysis (DEA) have to be used to measure efficiency in a multidimensional space, using six inputs and two outputs. It appears from the results that the highest efficiency farms are in the Netherlands, and then Germany and... |

| With the enforcement of the Water Framework Directive 2000/60/EC (WFD), policy makers are required to pursue the improvement of the use efficiency of the water resources in the agricultural sector. For this purpose, we suggest a methodology to perform an ex-ante analysis of the efficiency of water pricing policies, based on a two stage DEA technique, by which it is possible to disaggregate the technical and the ecological efficiency of the policy. According to our results, we found that, coherently with the WFD principles, the direct pricing methods show the highest levels of efficiency. However, we have also found that some indirect pricing methods show relatively high levels of efficiency. Therefore, since the high cost for the management and... |

| This study examined changes in agricultural productivity at Benin in the context of diverse institutional arrangements using Data Envelopment Analysis (DEA).A time series data which consists of information on agricultural production and means of production were obtained from World Research Institute database, INSAE and rainfall data from AMMA database. The information was for a 43-year period (1961-2003); DEA method was used to measure Malquist index of total factor productivity to evaluate technical change efficiency and technological efficiency change across the country’s 12 provinces. A decomposition of TFP measures revealed whether the performance of factors productivity is due to technological change or technical efficiency change over the reference... |

| The primary objective of this study is to empirically determine whether North American Free Trade Agreement (NAFTA) has contributed to increased agricultural productivity in any of its member countries. Implementation of the NAFTA began on January 1, 1994. This agreement removed most barriers to trade and investment among the United States, Canada, and Mexico, in which all non-tariff barriers to agricultural trade between these countries were eliminated. Data Envelopment Analysis (DEA) and the Malmquist Productivity Index were used to estimate the total factor productivity change, technical change, and efficiency change of agricultural production for each NAFTA country. Then, using time series data, the efficiency changes in countries were compared to... |
