| The role of trust in eight selected agri-food chains in four EU countries is explored. The empirical analysis is based on a qualitative assessment of 28 expert interviews conducted in summer/autumn 2005. The findings suggest that trust is more pronounced among SMEs which are characterised by the existence of personal relationships between business partners. However, as is clear for pork breeders, if a source of distrust exists, trust may not fully develop. Also, if the general economic situation is difficult, the development of trust may be hampered, because all chain participants are struggling to command a share of a diminishing margin within the chain. Finally, if economic power is distributed unevenly, as is the case in Germany, Ireland, Spain and... |

| RESUMEN: El objetivo de este estudio es analizar la respuesta diferenciada del consumo de bebidas alcohólicas de las distintas regiones españolas ante cambios en los precios y la renta y simular las consecuencias de una variación del tipo de los impuestos especiales sobre bebidas alcohólicas. Para ello se han estimado las elasticidades renta y precio de tres tipos de bebidas alcohólicas (vino, cerveza y "otras bebidas alcohólicas") a través de un sistema completo de demanda tipo AIDS, utilizando un panel de datos anuales entre 1993 y 2000 para ocho grandes regiones españolas. Los resultados de este estudio permiten concluir que existen diferencias importantes en los hábitos de consumo de bebidas alcohólicas en los hogares entre las distintas regiones y... |

| This paper uses Data Envelopment Analysis to measure scale and technical efficiencies of 925 farms in rural Colombia and a Tobit model to identify the effects of land market characteristics on efficiency. Findings indicate that although larger farms are more scale efficient, they are not more technical efficient than small farms. Participation in land markets increases technical efficiency, indicating a positive potential role for market-based land reform. Further results show that intensity of violence in rural areas results in increased scale efficiency, allegedly through consolidation of land ownership. |

| This paper estimates farm household levels of technical efficiency and their determinants in Colombia, with particular reference to political violence (i.e., guerilla fronts, assassinations, kidnappings, and displaced population). An input-oriented stochastic frontier is estimated simultaneously with a technical inefficiency model that incorporates violence at the local level, using survey data from 822 farm households. The findings show that household productivity is lower in areas of high political violence, particularly with high incidence of guerrilla fronts and kidnappings. Should political violence be eliminated, the average Farrell's technical efficiency index of farm households in the sample would increase by an average of 6.4%, favoring households... |
