As the price of recreational visits is unobservable and commonly represented by researcher-assigned travel cost estimates, welfare change estimates generated by the travel cost method are ordinally measurable (Randall, 1994). For a potential solution to the resulting calibration problem we use...

Using count data models that account for zero-truncation, overdispersion, and endogenous stratification, we estimate the value of access to recreational parks. The focus is on the empirical estimation of the proportion of the wage rate that best approximates park visitors’ opportunity cost of...

We combine contingent behaviour with travel cost data to estimate the change in the recreational use value of a National Forest due to quality and price changes. Instead of the usual improvement scenario, a hypothetical deterioration in the conditions of the forest due to a fire is considered. A...

The change in waterfowl hunting benefits due to an increase in water deliveries to the levels required for biologically optimal wildlife refuge management at California's San Joaquin Valley National Wildlife Refuges are estimated with the Travel Cost Method, using both ordinary least squares and...

Con la ayuda del método del coste del viaje el valor de uso recreativo de un determinado espacio se define, simplemente, como el excedente del consumidor medido por debajo de la función de demanda estimada. Esta es una práctica suficientemente satisfactoria cuando se analiza el valor de...

Los espacios naturales realizan importantes funciones ambientales y recreativas cuyo valor no es recogido por el sistema de mercado. La economía ha desarrollado métodos específicos de valoración que permiten estimar los beneficios asociados a la existencia, conservación y disfrute de estos...

In a travel cost exercise, reported past visits to mount Jaizkibel, a natural area located in the Basque Country (Spain), are compared for convergent validity to stated intended future trips under the assumption that the natural resource's conditions will remain the same. In line with the...

Recent government legislation in South Africa (the National Environmental Management: Biodiversity Act, No.10 of 2004) calls for the removal of trout from ecosystems and habitats where they may cause harm. The elimination of trout would, however, undermine the tourism appeal of many upper...
