Última An Examination of the Relationship Between Subsidies on Production and Technical Efficiency in Agriculture: The Case of Cotton Producers in Greece AgEcon Emvalomatis, Grigorios; Oude Lansink, Alfons G.J.M.; Stefanou, Spiro E.. Subsidies on production have long been criticized for protecting producers from competition, and thus removing an incentive for efficient use of the resources. This study undertakes the examination of the impact of partially decoupled subsidies on the technical efficiency scores of cotton producers in Greece. The results indicate that compensatory area payments reduce the efficiency scores of the producers by diverting resources from products for which the subsidy is based on the area planted to the production of cotton, for which the aid is related to the volume of output.

Ano: 2008 URL: http://purl.umn.edu/6673 Dynamic Decomposition of Total Factor Productivity Change in the EU Food, Beverages, and Tobacco Industry: The Effect of R&D AgEcon Emvalomatis, Grigorios; Stefanou, Spiro E.; Oude Lansink, Alfons G.J.M.. The main objective of this paper is to generate measures of TFP change for the food, beverages, and tobacco industry in the EU. Explicitly taking into account the fact that some of the inputs used in the industry are fixed in the short run, the generated measures of TFP change reflects the dynamic nature of the problem. The second objective is to analyse TFP change into its components and explicitly examine the effect of Research and Development (R&D) effort on TFP growth. Data are collected from EU KLEMS and the OECD Structural Analysis database. The data contain country-level information on output volume, input prices and capital stock, as well as R&D expenditure for the food, beverages, and tobacco industry for the 15 “old” EU Member States....

Ano: 2009 URL: http://purl.umn.edu/58011 Dynamic adjustments in the Dutch greenhouse sector due to environmental regulations AgEcon Verreth, Daphne M.I.; Emvalomatis, Grigorios; Bunte, Frank H.J.; Oude Lansink, Alfons G.J.M.. Horticultural firms are dependent on energy to produce, while policy makers focus on reducing the use of energy and investment in energy-saving technologies. The paper aimed to asses Dutch greenhouse farmers‘ responses to policies that would affect prices of different energy inputs. The farmer’s behaviour is modelled in two steps: firms are assumed to maximize profit at given energy use level, and firms are assumed to minimize the discounted sum of energy costs. The model is estimated using farm survey data spanning the period 2001-2008. Short-run and long-run elasticities with respect to prices and investments in energy-using technology are estimated. The greenhouse sector shows a fast adjustment of energy capital towards its long-run equilibrium. This...

This paper provides an assessment of the protein content of U.S. trade in dairy products and their potential impact on U.S. milk prices. The protein in imports of MPC, Casein & Albumins accounted for 5-6 percent of protein in total U.S. consumption during the period 1997-2002.

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...

Ano: 2011 URL: http://purl.umn.edu/104651 Dynamic and static behaviour with respect to energy use and investment of Dutch Greenhouse firms AgEcon Verreth, Daphne M.I.; Emvalomatis, Grigorios; Bunte, Frank H.J.; Oude Lansink, Alfons G.J.M.. Dutch greenhouse horticultural firms are energy-intensive and major emitters of greenhouse gases. This paper develops a theoretically consistent model that is able to describe the greenhouse firms` behaviour regarding energy use and investments in energy technology. The behaviour of the firm is modelled using a combination of a dynamic cost function and a static profit function framework. This paper derives the optimal quantity of energy and energy capital from the link between these two functions. The model is applied to a panel of 97 Dutch greenhouse firms over the period 2001-2008. The results show that most Dutch greenhouse firms shift from being net electricity users to net electricity producers in the long run. Investing in energy capital contribute...
