| The introduction and communication of new technologies in the food industries has given rise in the past to some scientific uncertainty that hampers informed choice. Here we draw upon the case of Genetically Modified (GM) technology and, in particular, on different types of GM food, to investigate consumers’ behavioural reactions to GM food as well as their willingness to pay for avoiding GM food in three EU countries, Denmark, GB and Spain in 2007. Our unique contribution lies in that our empirical analysis concerns two food products containing different characteristics. In particular, we compare consumers’ reactions to cornflakes (to represent a processed food) and tomatoes (to represent a 'fresh' food) juxtaposed with GM and conventionally produced... |

| In recent years, health risks have received increasing attention among consumers and created interest in analysing the relationship between food scares, food consumption and market prices. One of the most relevant and recent food scares is the avian influenza that has had important effects not only on human and animal health, but also on the economy. We assess effects of avian influenza on price transmission along the Egyptian poultry marketing chain. Although Egypt has been one of the most affected countries by avian influenza, this article is the first attempt to understand this food scare’s impacts on Egyptian poultry markets. In doing so, a multivariate smooth transition vector error correction model (STVECM) is applied to monthly poultry price data.... |

| The objective of this paper is to analyse some of the most relevant relationships among macroeconomic variables and the agricultural sector in Tunisia. Three alternative models are specified and estimated: a VAR in levels, an unrestricted Vector Error Correction Model (VECM), and a Restricted VECM in which long-run relationships among the relevant variables are identified. In all models short-run dynamics are analysed through the use of Generalised Impulse Response Functions. Results indicate that alternative model specifications generate different short-run dynamics. Long-run identification seems to be a necessary condition for obtaining consistent economic results. |

| In recent years, consumer concerns on environmental and health issues related to food products have increased and, as a result, the demand for organically grown production has grown. Higher costs of production and retailer margins generate a gap between real prices and those that consumers are willing to pay for organic food. In this article, consumer willingness to pay for organic food in two Spanish regions is analyzed. Markets in both regions are segmented considering consumers lifestyles. Results indicate that consumers concerned about healthy diet and environmental degradation are the most likely to buy organic food, and are willing to pay a high premium. Organic attributes are easily identified in perishable products as the premium consumers... |

| The purpose of this paper is the evaluation of the investment decision under uncertainty and irreversibility allowing for long run inefficiency. The analysis has been applied to a 158 Spanish olive farms using FADN data set. A real option approach has been used to analyse the decision to invest under uncertainty and irreversibility, and a dynamic stochastic frontier model has been developed to estimate the long run technical efficiency and it persistence. The results show that the technical inefficiency persistence parameter is fairly low to unity, which means that small technical inefficiency is transmitted to the next time period. The olive groves investment is irreversible and characterized by uncertainty on price and discount rate. An increase of... |

| RESUMEN: En este trabajo se analiza la demanda de alimentos en España considerando la relación existente entre salud y dieta. Se plantea la maximización de una función de utilidad que depende de las cantidades demandadas de los distintos alimentos y del nivel de salud alcanzado, sujeto a dos restricciones: la presupuestaria y la relativa a la función de producción de salud. La solución al problema conduce a la estimación conjunta de un sistema de ecuaciones con dos componentes, una ecuación referida a la calidad de la dieta y un sistema de demanda de alimentos. Los resultados obtenidos indican, por un lado, que la introducción de la calidad de la dieta en un sistema de demanda (frente a un modelo que incluya únicamente renta y precios) modifica las... |

| Resumen El análisis de las relaciones de precios existentes en un determinado sector permiten, por un lado, ofrecer una idea aproximada del funcionamiento de los mercados y, por otro, anticipar respuestas ante shocks inesperados en mercados relacionados. El objetivo de este estudio se ha centrado en el análisis de la transmisión de precios entre los principales mercados de ovino en España. Para llevar a cabo este estudio se ha adoptado un enfoque econométrico que ha tenido en cuenta las propiedades estocásticas de las series, la posible naturaleza multivariante de los procesos de transmisión, y la distinción entre el comportamiento a corto y largo plazo. Los resultados indican que los mercados de ovino se encuentran bastante interrelacionados pudiéndose... |

| This paper has analysed the import demand for virgin olive oil in the EU and more precisely in the Italian market, as it concentrates more than 80% of EU imports, aiming to determine the relative position of Mediterranean EU and non-EU countries exports and their degree of substitutability or complementarity. The methodology used is based on the specification of a Threshold Almost Ideal Demand System in which special attention has been paid to the stochastic properties of the series involved. In an empirical context, the paper has aimed to provide a set of import demand elasticities that can be useful in trade models. Results point to Spain as the leader in the Italian virgin olive oil market. It is expected that this position will be maintained in the... |

| We focus on determining the impacts of government programs on farms technical inefficiency levels. We use Kumbhakars (2002) stochastic frontier model that accounts for both production risks and risk preferences. Our theoretical framework shows that decoupled government transfers are likely to increase (decrease) DARA (IARA) farmers production inefficiencies if variable inputs are risk decreasing. However, the impacts of decoupled payments cannot be anticipated if variable inputs are risk increasing. We use farm-level data collected in Kansas to illustrate the model. |

| The influence of risk perception and risk attitudes in the process of accepting genetically modified (GM) food is often ignored, and particularly whether both constructs (latent variables) have a combined effect in explaining consumer acceptance. Similarly, the inclusion of organic product standards juxtaposed to GM food is unknown. This paper attempts to shed some light on this question by examining the decision making process through the use of structural equation modeling (SEM). We use survey data from Spain and a set of theoretical constructs that allow us to identify independent mechanisms underlying individuals’ risk decision making. Our results suggest that the conceptualized model captures the decision making process, and that both perceptions and... |
