Travel cost models using the wage rate to value time make the implicit assumption that the value of time is equalized throughout the year. We develop a seasonal travel cost model that allows the value of time to vary by season. We estimate the model using data from a survey of recreational anglers in the Gulf of Mexico. We find that people’s value of time is 55% larger on average in the summer compared to other times of year and find substantial differences in derived welfare estimates if a time-constant value of time measure is used instead.

具有季节性时间约束的旅行成本模型中的跨期替代

使用工资率来评估时间的旅行成本模型隐含假设时间价值在一年中是相等的。我们开发了一个季节性旅行成本模型，允许时间价值因季节而异。我们使用来自墨西哥湾休闲垂钓者调查的数据来估计模型。我们发现，与一年中的其他时间相比，人们在夏季的时间价值平均高出 55%，并且如果使用时间度量的时间常数值来代替，则得出的福利估计会有很大差异。(JEL Q26, Q51)
