Última Influence of rural development policy targets on farm efficiency – An efficiency study of labour intensive grape growing family farms AgEcon Manevska-Tasevska, Gordana; Hansson, Helena. The aim of this study was to provide an empirical analysis of the performance of Macedonian grape-growing family farms assessed in terms of technical, allocative, and economic efficiency and to relate aspects targeted in the Rural Development Program (RDP) to the efficiency scores. The study was based on a two-step efficiency analysis, applying Data Envelopment Analysis (DEA), in the first step, and Tobit regression analysis in the second step. Data were collected between 2006 and 2008 through face-to-face interviews with 300 grape growers in the Tikvesh vineyard district in Macedonia, each represented by the three-year average of inputs, outputs and prices. The results indicated a large potential for efficiency improvement. The average efficiency was...

Ano: 2010 URL: http://purl.umn.edu/90807 EXPLAINING ECONOMIC INEFFICIENCY OF NEPALESE RICE FARMS: AN EMPIRICAL INVESTIGATION AgEcon Dhungana, Basanta R.; Nuthall, Peter L.; Nartea, Gilbert V.. Efficiency has been proven to be an important managerial tool in improving total factor productivity in agriculture. The four sources of economic inefficiency: allocative, technical, pure technical and scale inefficiency of a sample of seventy-six Nepalese rice farmers were examined using the data envelopment analysis (DEA) decomposition method. The inefficiency indices computed by the DEA were then used as the dependent variable in a Tobit (censored) regression model using decision- makers’ attributes as the explanatory variables. The results revealed relatively large inefficiencies among the farms sampled. The average economic, allocative, technical, pure technical and scale inefficiencies were 34%, 13%, 24%, 18%, and 7% respectively. There is also a...

Ano: 2000 URL: http://purl.umn.edu/123630 Farm Income Variability and the Supply of Off-Farm Labor by Limited-Resource Farmers AgEcon Vergara, Oscar; Coble, Keith H.; Patrick, George F.; Knight, Thomas O.; Baquet, Alan E.. We study the relationship between the off-farm labor decision and the limited-resource farmers’ and spouses’ off-farm experience, education, and sources of income. We found that farmers’ and spouses’ off-farm experience and wages are significant factors in explaining the off-farm labor supply decision. Contrary to expectations, farm income variability is not significant in the farmers’ and spouses’ decision to see off-farm work. The off-farm labor supply of farmers and their spouses is negatively correlated with income transfers from the government. It was also found that the spouse is a residual supplier of on-farm and off-farm labor.

Ano: 2004 URL: http://purl.umn.edu/43394 Agricultural Commercialization in the Uplands of Northern Vietnam: How to Achieve Both Poverty Reduction and Environmental Sustainability Goals? AgEcon Keil, Alwin; Saint-Macary, Camille; Zeller, Manfred. Income growth and urbanization in developing countries have enlarged markets for highvalue agricultural commodities. However, there are concerns that lacking access to physical, financial, and human capital, as well as infrastructure and institutions limit the ability of the poor to participate in and benefit from such commercial agricultural activities. There may further be a trade-off between wealth enhancing effects of intensive commercial agriculture and adverse long-term effects on farmers’ livelihoods due to natural resource degradation. This study provides empirical evidence on these crucial issues and derives related policy recommendations using the example of Vietnam. Here, economic growth has boosted the demand for animal products and,...

Ano: 2011 URL: http://purl.umn.edu/114487 What is the Effect of Operational Managerial Practices on Dairy Farm Efficiency? Some Results from Sweden AgEcon Johansson, Helena; Ohlmer, Bo. The article aims to investigate how operational managerial practices can contribute to improved farm level efficiency at dairy farms. Operational managerial practices are defined as animal health, breeding, and feeding practices. The main contribution of the article is that it investigates aspects that can be adjusted every day to improve farm efficiency. Aspects describing each of the considered managerial practices are regressed on farm level data envelopment efficiency scores based on farm level data from Sweden. The results show that changes in breeding and feeding practices can lead to improved efficiency. Breeding exactly the number of heifers that is needed for replacement of the dairy cows negatively affects long-run technical efficiency. On the...

Ano: 2007 URL: http://purl.umn.edu/9845 Determinants of the Fallowing Decision in Kosovo AgEcon Sauer, Johannes; Davidova, Sophia; Latruffe, Laure. The key question of this paper is why farmers in Kosovo leave land fallow when the total land of their farms is rather small and households are rather large. In order to elicit some barriers to land utilisation in Kosovo, the paper is based on a comprehensive survey carried out in 2005 investigating agricultural households’ perceptions of production and market conditions, and employs several households and farm characteristics to empirically approximate the significance of different factors for leaving land fallow and not using it for production purposes. Three different econometric models are used expected to fit the data distribution. All estimated model specifications show a statistical significance at a satisfactory level and no severe signs of...

Ano: 2009 URL: http://purl.umn.edu/53278 USING DEA TO EVALUATE EFFICIENCY OF HIGHER EDUCATION AgEcon Toth, Reka. The aim of the higher education reform process both in Hungary and in the European countries is establishing a competitive, qualitative higher education with efficiently operating institutions. The question of efficiency needs increased attention not only because of the decline of the state support but also the rapid raise of the student mass. In the education system it’s not easy to measure the output of the services. The situation is more complicated if an organisation or a sector has multiple inputs and outputs. In this case a possible method of determining efficiency is Data Envelopment Analysis. In my paper I’d like to introduce this method and use it to compare the efficiency of higher education systems. Furthermore I am examining whether their...

Ano: 2009 URL: http://purl.umn.edu/51626 Maize boom in the uplands of Northern Vietnam : economic importance and environmental implications AgEcon Keil, Alwin; Saint-Macary, Camille; Zeller, Manfred. In Vietnam, the demand for meat products has grown dramatically due to rapid economic growth and urbanisation and is expected to further increase in the future. Being the primary source of feed for the country’s livestock and poultry industry, maize has become the second most important crop after rice. While this maize boom has the potential to reduce rural poverty, it promotes the expansion of agricultural cultivation into fragile agro-ecological zones, often leading to deforestation and soil degradation, especially in the uplands. Using empirical evidence from mountainous Yen Chau district in north-western Vietnam, the objective of this paper is to investigate the current economic importance and environmental implications of maize cultivation....

Ano: 2008 URL: http://purl.umn.edu/92829 Technical and Economic Efficiency of Laying Hen Farms in Konya, Turkey Rev. Bras. Ciênc. Avic. Dogan,N; Kaygisiz,F; Altinel,A. ABSTRACT This study was carried out to determine the technical and economic efficiency levels of laying hen farms and factors affecting the efficiency scores. For this purpose, a personal interview was carried out. Technical and economic data of 39 laying hen farms consisting their inputs and outputs over the period 2013-2015 was formed the material of this study. Efficiency levels were estimated by using Data Envelopment Analysis (DEA). Mean technical efficiency score of the enterprises were determined as 98.6%. Also 48.7% of the enterprises were determined fully technical efficient. On the other hand, mean economic efficiency of the enterprises was determined as 88.8%, while only 17.9% of the enterprises were fully economic efficient. In order to...
