    Abstract

    RESUMEN: En este trabajo se presenta una comparación entre dos métodos de valoración de preferencias declaradas: la ordenación contingente y el experimento de elección. Se incluye una aplicación empírica en la que se valoran los impactos que una determinada forestación de terrenos agrícolas en Cataluña tendría sobre la función recreativa, de absorción de CO2 y de protección frente a la erosión de los bosques. Los resultados muestran diferencias entre los valores obtenidos a partir de los dos métodos, siendo los del método de elección significativamente mayores. Además, esta divergencia se mantiene cuando se comparan observaciones pairwise obtenidas directamente a través del método de elección con las simulaciones pairwise procedentes de la ordenación contingente. ABSTRACT: This paper presents a comparison between two stated preference methods: the contingent ranking and the choice experiment. An empirical application is included, involving the valuation of the effects that would have a specific program to convert some agricultural land into forest land in Catalonia. The valuation exercise considers a forest recreational function, carbon storage, and erosion protection. The results show some differences between the values derived from the two methods, with the choice experiment values being significantly greater. Moreover, the differences are kept when comparing pairwise observations derived from the choice experiments with simulated pairwise observations derived from the contingent ranking.
