Valuing Time in Travel Cost Demand Analysis: An Empirical Investigation
实证检验了旅行成本需求模型中基于收入的机会时间成本假设，并提出了一个基于部分休闲者劳动力市场非均衡的替代模型，发现非均衡模型对某些个体是必要的，这增加了调查信息需求。
The opportunity cost of time is usually a significant part of the price variable in the travel cost demand model. Thus, its accurate measurement is important to the estimation of demand and benefit valuation for nonmarket resources. This paper empirically tests models which assume that income is the basis for opportunity time cost with an alternative "pooled" model based on a disequilibrium labor market for some recreationists. Acceptance of the hypothesis that disequilibrium models may be necessary for some individuals implies increased survey information requirements so that the appropriate model can be applied to each individual.
