Incorporating Uncertainty and Cero Values into the Valuation of Protected Areas and Species AgEcon
Hurle, Jesus Barreiro; Garcia, Jose Maria Casada; Perez y Perez, Luis.
Under the Spanish conservation law, compensation is envisaged for the damage associated with all actions that reduce the quantity or quality of protected areas and species. This paper provides a tool to evaluate the monetary equivalent of this damage. We conduct a contingent valuation exercise to estimate the existence value related to protected areas and species in Aragon. This estimate is then reconsidered including the possibility of zero bids and also the possibility of uncertain preferences for non-familiar goods. Considering these two effects, mean values are reduced significantly giving support to previous recommendations of dividing by two contingent valuation estimates from dichotomous choice question formats.

Marginal Farmers and Agri-Environmental Schemes: Evaluating Policy Design Adequacy for the Environmental Fallow Measure AgEcon
Hurle, Jesus Barreiro; Goded, Maria Espinosa.
This paper examines the factors affecting farmer's participation in an agri-environmental scheme (AES) in marginal areas implying few changes in the traditional farm management (environmental fallow). The enrolment theoretical micro-economic model reveals that farmers` (extrinsic) factors as well as decision maker's (intrinsic) factors are important for farmer's participation, without disregarding the role of social capital. The farm and farmer characteristics (intrinsic factors) as well as the influence of the social capital have been tested trough the specification and estimation of an adoption model for dry-land marginal farmers in Granada (southern Spain). 300 farmers with cereal dry-land specialization have been surveyed in order to identify factors...

Una nota sobre la recuperacion de costes de los servicios del agua en la cuenca del Gallego AgEcon
Perez y Perez, Luis; Hurle, Jesus Barreiro.
Up to date, water management in Spain has been focused on supply approaches, with the result of providing consumers with this resource at a low price. Developments in the institutional framework regulating water management in the European context (mainly the implementation of the Water Framework Directive) have shifted this approach in order to promote sustainable water use. To achieve this objective, tariff policy must now take into account the water services cost-recovery principle for its different uses. Within this context, this paper estimates the public capital stock related to water supply and assesses the existing level of cost-recovery related to that stock. The methodology used, compares the tax level needed for full-cost recovery with actual...
