Evaluacion de impactos ambientales derivados de estrategias de restauracion a traves de las decisiones de jurados de ciudadanos AgEcon
Alvarez-Farizo, Begona; Gil, Jose Maria; Howard, B.J..
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...

Nonlinearities in the US corn-ethanol-oil price system AgEcon
Serra, Teresa; Zilberman, David; Gil, Jose Maria; Goodwin, Barry K..
We use a smooth transition vector error correction model to assess price relationships within the US ethanol industry. Daily ethanol, corn and oil futures prices observed from mid-2005 to mid-2007 are used in the analysis. Results indicate the existence of an equilibrium relationship between ethanol, corn and oil prices. However, only ethanol prices adjust, in a non-linear fashion, to deviations from this long-run parity. Generalized impulse response functions indicate that a shock to both oil and corn prices causes a change in ethanol prices of the same sign. Ethanol responses usually reach a peak after about 10 days of the initial shock and fade away within 35 days.

A choice experiment method to assess vegetables producers’ preferences for crop insurance AgEcon
Mercade, Lluc; Gil, Jose Maria; Kallas, Zein; Serra, Jordi.
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...

MODELLING IMPORT DEMAND SYSTEMS WITH NONSTATIONARY DATA: AN APPLICATION TO THE FRENCH IMPORTS OF VIRGIN OLIVE OIL AgEcon
Ben Kaabia, Monia; Gil, Jose Maria.
This paper aims to provide a flexible methodological framework to estimate import demand models, which explicitly considers the stochastic properties of data and the endogenous/exogenous nature of some variables. The French imports of virgin olive oil have been used as a case study with Spain, Italy and the Rest of the World as main suppliers. The methodological framework starts by the specification a reduced-form VAR. Appropriated exogeneity tests show the exogeneity of Total Real Imports, indicating the appropriateness of estimating a conditional model. Two cointegration relationships have been found. Several restrictions have been tested in order to identify them as AIDS equations. From structural coefficients of the restricted cointegrated vectors...

Structural Equation Modelling of Consumer Acceptance of Genetically Modified Food (GM) in the Mediterranean Europe: Spain, Greece and Italy. AgEcon
Costa-Font, Montserrat; Gil, Jose Maria.
The inception of genetic modification (GM) techniques in food production conveys both opportunities - improve food production technologies and/or product differentiation - and risks - dread of a change of the technological status quo, ambiguity in the food properties..…. Hence, some research has been devoted a careful understanding of consumer's reactions towards to GM food. However, unavoidably individual's perceptions involve taking into account several factors at a time that cannot be taken as given or exogenous such as traditional food values and trust in information sources primarily. This paper contributes to the literature by examining the behavioural process that drives individual's perceptions to GM food using a methodology that allows accounting...

Are The Spanish Citrus Farms Efficient? AgEcon
Lambarraa, Fatima; Gil, Jose Maria; Serra, Teresa.
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,...

La certificacion como estrategia para la recuperacion de la confianza del consumidor en la adquisicion de la carne de ternera AgEcon
Barrena Figueroa, Ramo; Sanchez Garcia, Mercedes; Gil, Jose Maria; Gracia, Azucena; Rivera, Luis M..
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...

Investment rigidity and policy measures AgEcon
Serra, Teresa; Stefanou, Spiro E.; Gil, Jose Maria; Featherstone, Allen M..
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...

Differential Uncertainties and Risk Attitudes between Conventional and Organic Producers: The Case of Spanish COP Farmers AgEcon
Serra, Teresa; Zilberman, David; Gil, Jose Maria.
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...

Price transmission in the Spanish bovine sector: the BSE effect AgEcon
Hassouneh, Islam; Serra, Teresa; Gil, Jose Maria.
A regime-switching vector error correction model is applied to monthly price data to assess the impact of BSE outbreaks on price relationships and patterns of transmission among farm and retail markets for bovine in Spain. To evaluate the degree to which price transmission is affected by BSE food scares, a BSE food scare index is developed and used to determine regime-switching. Results suggest that BSE scares affect beef producers and retailers differently. Consumer prices are found to be weakly exogenous and not found to react to BSE scares, while producer prices conversely adjusted. The magnitude of the adjustment is found to depend on the magnitude of the BSE scare.

Spanish Consumers' Attitudes and Acceptability towards GM Food Products AgEcon
Angulo, Ana Maria; Gil, Jose Maria.
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....

Price Transmission Asymmetries in the Spanish Lamb Sector AgEcon
Ben Kaabia, Monia; Gil, Jose Maria; Boshnjaku, L..
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...

The impact of the CAP reforms on the efficiency of the COP sector in Spain AgEcon
Lambarraa, Fatima; Stefanou, Spiro E.; Serra, Teresa; Gil, Jose Maria.
The arable crop sector (COP) occupies a prominent position within the European Union’s agricultural sector. Within Spain, the COP sector accounts for almost a third of total Agricultural Guidance and Guarantee Fund expenses, and a half of the utilised agricultural area. The COP sector is not only relevant because of its physical and economic magnitude, but also because of the political attention it receives. The Common Agricultural Policy reforms that occurred during the 1990s paid special attention to this sector. This paper aims at determining the impacts of Agenda 2000 on a sample of Spanish COP farmers’ production decisions by using an output-oriented stochastic distance function. The distance function allows assessing the reform-motivated changes on...

Initial Endowment Effects in Multi-Unit Vickrey Auctions AgEcon
Akaichi, Faiçal; Nayga, Rodolfo M., Jr.; Gil, Jose Maria.
We report the result of experiments designed to assess the effect of initial endowments on willingness to pay values elicited from multi-unit Vickrey auctions. Comparing bids from an “endow and upgrade” approach with the “full bidding” approach, we find that the direction of the endowment effect generally depends on the number of endowed units of the conventional product that subjects are willing to give up in exchange for units of the upgraded product. The endowment effect is “reverse” when the number of units that participants are willing to give up is lower or equal to the number of remaining endowed units. However, we generally find an endowment effect when the number of units a participant is willing to give up is higher than the number of remaining...

Effects of policy instruments on farm investments and production decisions in the Spanish cop sector AgEcon
Kallas, Zein; Gil, Jose Maria; Serra, Teresa.
Our paper asses the impacts of the partially decoupled (PD) scheme, implemented during the 1990s and first half of the 2000s in the framework of the Common Agricultural Policy (CAP), on on-farm investment as well as on other production decisions. The Spanish COP sector was taken as a case study due to its economic and political relevance. The empirical analysis is applied on farm-level data from the Farm Accountancy Data Network (FADN), observed from 2000 to 2004, based on. We use a reduced-form application of the dual model of investment under uncertainty and a system of censored and non censored equations is estimated. PD payments are found to increase short-run production and to generate a statically significant increase in the investment in farm...

A Calibrate Auction-conjoint Experiment to Elicit Consumer Valuation of Sustainable Farming: Is Agro-systems Preservation Relevant? AgEcon
Avitia, Jessica; Costa-Font, Montserrat; Gil, Jose Maria; Lusk, Jayson L..
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’...

On the Use of Multi-Unit Auctions in Measuring Consumers’ Willingness to Pay for Food Products AgEcon
Akaichi, Faiçal; Nayga, Rodolfo M., Jr.; Gil, Jose Maria.
This paper proposes the use of multi-unit auctions in studying consumers’ willingness to pay (WTP) for food products in a multi-unit shopping scenario. We show how this method can overcome the limitations of single-unit experimental auctions in obtaining useful information related to WTP for not just the first unit but also subsequent units of a product, the demand curve, consumer surplus, the determinants of consumers’ WTP for each auctioned unit, and the effect of potential price discount strategies.

Spanish Demand for Food Away From Home: A Panel Data Approach AgEcon
Angulo, Ana Maria; Gil, Jose Maria; Mur, Jesus.
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...

NUTRIENT EFFECTS ON CONSUMER DEMAND: A PANEL DATA APPROACH AgEcon
Dhehibi, Boubaker; Gil, Jose Maria; Angulo, Ana Maria.
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.
