BREVE CURRRICULUM VITAE

Area de Investigación

Actualmente, mi campo de investigación, se centra en la Economía del Medio Ambiente y, más concretamente, en la valoración económica de bienes ambientales y públicos a través de las técnicas de preferencias declaradas y preferencias reveladas. Mi tesis doctoral -Valencia 1996- (La demanda de servicios recreativos de espacios naturales: aplicación del método de valoración contingente al Parque Natural de l'Albufera ), consistió, básicamente en la estimación del valor de uso del Parque Natural de l'Albufera a través del método de Valoración Contingente y del método del Coste de Viaje. La información obtenida de la aplicación de dichos métodos puede resultar de gran utilidad para la Administración que ha de decidir sobre el uso más conveniente que se le ha de dar al parque (análisis coste-beneficio); también es útil para los tribunales de justicia que tienen que determinar las indemnizaciones por el daño infligido al medio ambiente y, por último, las organizaciones de defensa de la naturaleza también pueden encontrar útil esta información ya que les indica cuál es el valor (monetario) del patrimonio natural que defienden.

En España, existen estudios previos donde se ha aplicado también la técnica de valoración contingente, cabe destacar los de Pere Riera , Diego Azqueta, Luis Pérez y Pérez, Carmelo León, J. Calatrava, etc. En Europa, uno de los grandes investigadores del tema es Bengt Krsitröm del Departamento de Economía Forestal de la Swedish University of Agricultural Sciences . En el resto del mundo, existen bastantes investigadores de gran relevancia en este área de conocimiento, como son, entre otros, R.C. Mitchell, R.T. Carson, M. Hanemann , Glenn W. Harrison , N. Bockstael, A.M. Freeman, V.K.Smith, N. Hanley, etc.

Abstract. This study examines the factors that explain the differences observed between the industrial land prices offered by the public sector and those offered by the private sector by means of estimating three hedonic pricing models. The results obtained show that location, defined as the distance to a highway, the distance to the city business district and the distance to the capital of the province, have an important impact on industrial land value. However, this impact is greater when private developers provide the land. Other variables considered, such as who is behind the provision of the industrial land, have an important impact on sale prices.

 Abstract. As a consequence of the decline of central harbour sites and the relocation of port activities to the outskirts of cities, today waterfront redevelopment has become a key issue in the urban revitalisation policies of port cities. Although we are aware that city-port regeneration has strong links with the real estate market, our purpose here is very different. In particular, the contingent valuation method (CVM) has been applied in order to obtain the nonmarket benefits of the environmental and urban improvements derived from redeveloping some port-related areas for recreational and leisure purposes in the city of Castelloèn, Spain. To date, no previous study has attempted to apply this method to this policy issue. The result is that CVM provides useful information in this context, however, like any methodology, it has its limitations and it cannot provide a definitive answer to this policy issue. Finally, the estimated benefits are compared with the costs of the provision of such recreational and leisure facilities within a cost - benefit analysis framework, and the main finding is that benefits can plausibly exceed costs.

Abstract: In this paper we address, from a double perspective, the social valuation of transport improvements caused by the construction of a new motorway. First, we estimate the value citizens confer on this infrastructure as a whole. Second, we assess the time savings and the reduction in the risk of accidents the new motorway might be expected to bring about in relation to roads used at the moment. To do this, we use two approaches based on individuals’ stated preferences: the contingent valuation method and conjoint analysis. The results show the social benefits of this project to be positive, although to what extent depends on initial assumptions. The information provided in this study will be useful to public managers since it can be incorporated in a cost-benefit analysis on the social profitability of this public investment.

Abstract: In this paper, the Contingent Valuation Method (CVM) is applied in order to estimate the social benefits of a set of environmental and urban improvements planned for the waterfront of the City of Valencia (Spain) as a consequence of the expansion and restructuring of its trading port. As the data show a high rate of zero responses we applied the Spike model, one of the most recent models in CVM literature, since traditional models (Logit and Probit) are not suitable given the characteristics of our data. The non-parametric  approach is also applied in order to test the validity of the Spike model. The results show certain similarities between the Spike model and the non-parametric approach.

Abstract: In this paper the Contingent Valuation Method is applied in order to estimate the recreationa use value of L'Albufera Natural Park (Spain). A total of 501 ramdoly selected park visitors were surveyed for this purpose. The results obtained show that the mean WTP is 590 pesetas per person and visit, a amount that is some lower than obtained in previous studies conducted in Spain due to th higher rate of visits to this natural park than in other natural parks located in Spain. A censored Tobit model was applied to estimate the most important determinats of individual WTP answers.

Abstract: Measuring economic value of certain types of non-market goods such as protected natural areas, provides valuable information on wich to base public sector decision-market related to their management e.g. investment in conservation and new amenities or recovery of degraded landscape. Two method are applied in this paper to estimate the recreational use value of L'Albufera Natural Park (Spain): the Contingent Valuation Method (CVM) and The Travel Cost Method (TCM). The results obtained are based on a survey of 501 park users carried out summer/autumn 1995 and they show how CVM yields a lower use value than TCM, although theoretically the opposite outcome was expected. Other recent studies in Sapin and elsewhere however are in line with these results.

Abstract: In this paper the authors analyse the advantages and drawbacks of the different instruments to internalize the externalities that are the result of an inadequate use ot the environment. In particular, they focus on the problems originated by an excessive use of nitrogen fertilizers in the agriculture and they show the role that a tax can play to reduce the use of this input.

Abstract: The purpose of this paper was to asses the effect of Spain's joinig the EC on such an important sector ot the chemical industry as fertilizers. The use of the technique known as residual imputation revealed that the share ot the EC products in this country's market has increased to a greater extent than that of this country's products in the EC market. However, aware of the limitations involved in using this technique, we found it necessary to broaden our analysis by introducing two additional factors: firtsly, the expanding market effect and, secondly, the effects of inplementing Community discipline in agricultural matters (Common Agricultural Policy).
