En los últimos años hemos asistido a una serie de vertidos contaminantes que han afectado tanto a espacios naturales como a áreas urbanas, industriales y rurales. Para mitigar sus efectos se hace necesaria una gestión integrada de las áreas productivas y naturales. Sin embargo, para que esta gestión sea eficaz es necesario considerar no sólo los efectos de las posibles medidas sobre la salud o los efectos biofísicos sobre el ambiente sino también la respuesta de los individuos a estos cambios. El objetivo de este trabajo se centra en la evaluación de los potenciales impactos, tanto ambientales como sociales, que se pueden derivar de las estrategias de restauración por vertidos. El enfoque adoptado se basa en la realización de un experimento de elección... |

Agricultural producers face many risks in their economic activity due to weather conditions, plant or animal diseases, price volatility, policy changes and so on. One of the management tools to deal with some of these risks is the crop insurance system. In Catalonia (North-East of Spain) farmers’ participation in crop insurance for vegetables is low. Only 5 percent of the vegetables area is insured, when in Spain, as a whole, this percentage is around 20 percent. Different reasons have been suggested to explain this low participation ratio such as low risk perception, risk diversification, insurance cost or crop damage assessment rules, among others. However, no systematic research has been undertaken to assess farmers’ preferences for crop insurance in... |

Spain occupies the first position in the European and Mediterranean rankings of citrus production and trade. In our analysis we assess the technical efficiency with which this sector is operating. The main objective of this study is to analyze productivity and technical efficiency of Spanish citrus sector through citrus farms with high orange production. A stochastic frontier production model is estimated in which the technical inefficiency effects are defined by the time-varying inefficiency model. A primal approach is used to decompose Total Factor Productivity (TFP) growth into its various components. Results indicate improvement in efficiency scores of Spanish citrus farms along the period studied. Allocative efficiencies, technical efficiency change,... |

Resumen El objetivo del trabajo se centra en analizar el efecto de la presencia de etiqueta en un producto con el fin de minimizar el riesgo percibido o la incertidumbre asociada al producto. El análisis ha sido realizado tomando como ejemplo la carne fresca de ternera, producto que ha presentado en Europa, en general, y en España, en particular, importantes problemas de salubridad o seguridad alimentaria que han generado una importante pérdida de confianza por parte de los consumidores e, indirectamente, una disminución de su consumo, lo que ha supuesto, a su vez, serias implicaciones sobre la oferta. Teniendo en cuenta el objetivo planteado, se especifica un modelo para analizar la disposición del consumidor a aumentar el consumo de carne de ternera si... |

This paper assesses the impacts of decoupled government transfers on production decisions of a sample of Kansas farms observed from 1996 to 2001. Our model allows for risk, risk attitudes and the intertemporal investment decisions. We also allow for different adjustments of the decision variables depending on the predominant economic conditions. The theoretical model is estimated using the threshold regression methods proposed by Hansen (1999). Threshold effects are allowed to characterize the behavior of output supply and quasi-fixed and variable input demand.. The econometric results support the existence of three regimes characterized by different economic behavior. Our analysis suggests that in a dynamic setting with risk and non-risk neutral economic... |

The growing importance of economic factors in farmers decision to go organic has raised interest in characterizing the economic behavior of organic versus conventional farms. Published analyses so far have not considered differential uncertainties and farmers risk preferences between conventional and organic practices when comparing these techniques. Our article attempts to assess this issue. We use a model of farmer decision under risk to analyze the differential values between Spanish COP organic and conventional farms and to assess the incentives for adoption of organic practices. Results show that organic and conventional farms do have different abilities to control production risk as well as different risk preferences. Organic price premiums and... |

The objective of this paper is to analyse consumers’ attitudes and acceptability of GM food products in Spain. From the methodological point of view, a three-equation model of consumer behaviour is estimated assuming a kind of causal chain among the degree of knowledge, attitudes and buying intentions. Explanatory variables include socioeconomic characteristics of respondents as well as endogenous variables of the previous equations. The model provides a better knowledge of how attitudes and buying intentions towards GM food are formed. Higher educated consumers, more concerned about labelling information and less about price, and regular buyers of organic foods show a higher (not necessarily better) knowledge on GM technology and its consequences.... |

The analysis of asymmetries in the price transmission mechanism at different levels of the marketing chain provides some interesting information about the degree of competition in vertical related markets. The objective of this paper is to investigate the non-linear adjustments of prices along the lamb sector in Spain. The methodology used is based on the multivariate approach to specify and estimate a Threshold Autoregressive Model. Price relationships at farm, wholesale and retail levels are considered. Results indicate that in the long-run price transmission is perfect and any supply or demand shocks are fully transmitted to all prices in the system. In the shortrun, analyses suggest that the high degree of horizontal concentration among retailers allow... |

This paper analyses the role of agro-systems preservation on making food choices. It employs the “Calibrate Auction-Conjoint Valuation method” (CACM), which relates hypothetical conjoint valuation of product attributes with real market behavior using real economic incentives. The paper also allows comparing the hypothetical and nonhypothetical valuations in order to value the difference between the theoretic and the incentive-compatible WTP for a same respondent and within a single experiment. Thus the paper aims at testing for: 1) the internal consistency on people’s behavior towards sustainable agriculture, and 2) the relevance of the price attribute versus agro-ecosystems preservation for a fresh product. Results suggest that Spanish respondents’... |

In this paper, the Spanish demand for food away from home is analysed. A panel data set is built and appropriate techniques for estimating limited dependent variable models have been applied. Results indicate that where there are zero expenditures, these are largely due to infrequency of purchase rather than to abstention or to economic reasons. Furthermore, important differences appear among households. On the one hand, those households whose head is a highly-educated person, male, young and living on a salary in a large town are more likely to purchase food away from home. On the other hand, increases in income only provokes more than proportional increases in expenditure for those households headed by an unschooled person, a female or a person older... |

The objective of this paper is to analyze the Spanish demand for food taking into account the consumer's concern about the relationship between food diet and health. This concern is forcing food demand analysts to assume that consumer utility is a function of nutrients instead of simply the food products themselves. A CBS demand model has been considered to model the new demand function obtained, which is estimated with a complete panel data set. Ten broad categories, nine nutrients and the most relevant socio-economic variables have been considered. Finally, after an appropriate model selection strategy, expenditure, price and nutrient elasticities, as well as main sociodemographic effects, have been calculated. |
