The effects of Nutritional Labels on Obesity

Loureiro, M.L, Yen, S., Nayga, R. (2012) “The effects of Nutritional Labels on Obesity” Agricultural Economics, 43(3), 333-342.

Abstract

This study examines the relationship between nutritional label use and obesity using switching regression. Results for treatment effect show that nutritional labels play a role in reducing obesity among users of nutritional labels, notably among women. The average body mass index (BMI) for men who read nutritional labels is 0.12 point lower than men who do not read them, while women who are users of nutritional labels have 1.49 points lower BMI than women who do not read labels. These findings imply that health education campaigns can employ nutritional labels as one of the instruments for reducing obesity.

Estudio de la causalidad de los incendios forestales en Galicia

Barreal, J., Loureiro, M.L., Picos, J. (2012) “Estudio de la causalidad de los incendios forestales en Galicia” Revista de Economía Agraria y de los Recursos Naturales, 12(1), 99-114.

Abstract

The goal of this research is to analyze the importance of the main factors contributing to the occurrence of wildfires in Galicia. The econometric models are specified taking into account as a dependent variable the number of fires and affected area, while these depend on a number of explanatory variables, including climatic and socio-economic characteristics. Based on the obtained results, we conclude that public policies should be oriented to re-structuring the agro-livestock sector, considering the evolution of the population pyramid, and new land uses. Such policies can help to reduce wildfires in Galicia.

Are Valuations from Real Choice Experiments Comparable to those from Experimental Auctions?

Loureiro, M.L., Gracia, A., Nayga, R.J. (2011) “Are Valuations from Real Choice Experiments Comparable to those from Experimental Auctions?” American Journal of Agricultural Economics, 93(5), 1358-1373.

 

Abstract

Due to the importance of comparability and external validity of results, nonhypothetical experimental methods are increasingly used to elicit consumers’ willingness to pay for various goods. Two of the increasingly popular preference elicitation methods are the nonhypothetical choice experiments and experimental auctions. We conduct experiments to compare willingness to pay estimates elicited from both methods. Our results generally suggest that valuations elicited from experimental auctions can differ from those obtained from nonhypothetical choice experiments.

Valuing an EU Animal Welfare Label using Experimental Auctions

Gracia, A., Loureiro, M.L, Nayga, R.J. (2011) “Valuing an EU Animal Welfare Label using Experimental Auctions” Agricultural Economics, 42(6), 669-677.

 

Abstract
 
The aim of this article is to determine consumers’ valuation for an EU Animal Welfare (EU-CAW) Label for products providing higher animal welfare standards than the current legal requirements. Using revealed preference data from random nth price auction mechanism and two auction procedures, our results generally suggest that consumers are willing to pay a premium for an EU Animal Welfare (EU-CAW) Label for cured ham. This finding is consistent in both the endowment and full-bidding auction approaches we employed in our experiments conducted in Spain. The average premium that consumers are willing to pay for a cured ham with the EU-CAW Label ranges between 19% and 23% of the average price of the regular cured ham that is currently available in supermarkets.

Nuevas perspectivas sobre las políticas climáticas en España

Labandeira, X., Loureiro, M.L. (2011) “Nuevas perspectivas sobre las políticas climáticas en España” Economistas, 127: 82-86.

Resumen

Las políticas de cambio climático tienen un marcado componente energético y, por ello, se encuentran en el centro de un creciente debate sobre su diseño y efectos. En este trabajo se presentan los resultados de la reciente aplicación de un cuestionario que evalúa la disposición a pagar de una muestra representativa de la población por dos políticas para restringir las emisiones españolas de gases de efecto invernadero y las actitudes de la ciudadanía española sobre diversas opciones en este ámbito. Nuestras conclusiones permiten reconciliar la elevada concienciación social sobre estas cuestiones con la aplicación de determinadas políticas de precios, a diferencia de lo ocurrido en la realidad hasta el momento.

Identifying the scope effect on a meta-analysis of biodiversity valuation studies

Ojea, E., Loureiro, M.L. (2011) “Identifying the scope effect on a meta-analysis of biodiversity valuation studies” Energy and Resource Economics, 33(3), 706-724.

Abstract

Insensitivity to scope is an issue of much debate in contingent valuation (CV) even today. Although the literature about insensitivity to scope is abundant, the reasons for it are not yet well known. Through a meta-analysis of CV studies of biodiversity, the treatment of the different possible measures of the quantity of the good is explored in relation to scope sensitivity. Overall, the findings suggest that CV results are sensitive to the amount of the good being valued, although the result depends on how the environmental change is measured. Results support the use of absolute sizes when conducting CV studies.

Climate change, energy and social preferences on policies: exploratory evidence for Spain

Hanemann, M., Labandeira, X., Loureiro, M.L. (2011) “Climate change, energy and social preferences on policies: exploratory evidence for Spain” Climate Research, 48: 343–348.

 

Abstract

Spain faces a complex situation regarding its climate change policies. On the one hand, greenhouse gas emissions have shown an important increase since 1990, and are far above the Kyoto commitments. On the other hand, the country is likely to suffer significant impacts from climate change. To date, however, there has been a rather limited application of corrective policies, particularly with regard to energy prices. Indeed, although Spanish citizens are generally very concerned about climate change, price increases in the energy sector have traditionally been opposed. In the present paper, we offer suggestions for future policies, showing that Spanish households, in general, are strongly in favour of the implementation of a green electricity program, which reduces greenhouse gas emissions, although it makes electricity more expensive for an interim period. Data from a telephone survey representative of the Spanish population which we carried out immediately prior to the Copenhagen climate summit, show that people were willing on average to pay an increase of 29.91€ per month per household over the current electric bill. Our results also show that younger ­individuals living in the Mediterranean area are more likely to pay for this green electricity program.

Ethical Considerations and Food Demand

“Ethical Considerations and Food Demand” 2011. Edit: Jayson Lusk, Jutta Roosen  & Jay Shogren. Oxford University Press.

Capítulo de libro

 

Abstract

Food is becoming more and more an item on the political agenda around the world. Ethical guidelines may require minimal harm to animals, proper labor conditions, or good environmental conditions, among others. This article documents the importance of ethical attributes in current consumption patterns and shows multiple studies on the various aspects of ethical consumption. The objectives of this article are twofold: first, to provide some background information to contextualize the multiple ethical claims according to different underlying economic and physiological theories; and second, to assess the marginal value of each of the main ethical food claims present nowadays in the marketplace. Results with respect to the relative preferences toward the various ethical claims are described and discussed. With respect to consumers' preferences toward ethical claims, (GM)-free claims are the most valued ones in the marketplace worldwide. Implications of this result are discussed.
