Economic Valuation of Forest Resources Using Voluntary Labor Contribution : An Application of a Generalized Corner Solution Model

本研究旨在开发一种新的评估技术，通过将广义角解模型应用于森林志愿者的劳动力供给行为，使我们能够利用揭示的偏好数据来衡量森林生态系统的价值。这一方法的实证结果表明，森林生态系统的价值远远大于以往所述的偏好研究所估计的价值。这些事实表明，在参考水平表明森林被完全开发的情况下，过去研究中的值并不代表等同的变化。

The study aims to develop a new valuation technique that enables us to measure the values of forest ecosystems with the revealed preference data, by applying a generalized corner solution model to the labor supply behavior of forest volunteers. The empirical results of this approach showed that the values of forest ecosystems are much larger than those estimated by previous stated preference studies. These facts suggest that the values in the past studies were not the ones that represent the equivalent variation in the case when the reference level indicates the state of the forest being completely exploited.
