我们关注娱乐需求的随机效用模型中选择集的定义。特别是，我们关注用于定义选项集的空间边界。本文利用缅因州的一日游捕鱼模型，检验了参数和福利估计对空间边界变化的敏感性。我们发现，存在一定的阈值距离，超过该距离，在选择集中添加更多站点对估计结果的影响可以忽略不计。
We are concerned with the definition of choice set used in Random Utility Models of recreation demand. In particular, we are concerned with the spatial boundaries used to define choice sets. In this paper, using a model of day-trip fishing in Maine, we examine the sensitivity of parameter and welfare estimates to changes in the spatial boundary. We find that there exists some threshold distance beyond which adding more sites to the choice set has negligible effects on the estimation results.
