Abstract

RESUMEN - En este trabajo se presentan estimaciones de diferentes especificaciones de demanda para un espacio recreativo singular a partir de la información de entrevis-tas a visitantes y no visitantes. Tenemos en cuenta los problemas de forma funcional, de medición del coste y demanda, de elección de una técnica de muestreo y de trata-miento de la muestra. La consideración de estas alternativas permite elegir una especi-ficación en mejores condiciones y nos aleja de supuestos iniciales restrictivos. Los resultados en términos de predicción de la demanda y estimación del excedente son bastante divergentes, resaltando la importancia de comparar diferentes especificacio-nes que incluyan el espectro de opciones potenciales. SUMMARY - In this paper, we present estimates of several specifications of demand for a singular natural area using data from surveys on visitors and non-visitors. The estimates take into account the problems of functional form, measurement of the cost and of the demand, choosing sampling scheme, and handling the sample. Considering these alternatives allows us to select a specification of demand under improved condi-tions and frees us from initial restrictive hypothesis. The results in terms of prediction of demand and consumer surplus estimates are quite dissimilar, stressing the impor-tance of comparing various specifications that encompass a range of possible options.
