On-the-Job Search Behavior: The Importance of Commuting Time
基于搜索理论，研究发现通勤时间越长，求职努力越大，且在某些条件下呈凸性；但未来不确定性和流动性会削弱这一效应，为通勤者看似“无拘束”的行为提供了微观解释。荷兰数据支持模型，但未发现通勤时间效应因社会经济特征而异。
Using search theory, we show that job search effort is increasing and, under some conditions, convex in commuting time. We show that the effect of commuting time on job search effort levels may be small in case of uncertainty caused by future job and residential moving behavior. Thus, we provide a microeconomic explanation for the finding that commuters behave as if they are footloose. Our empirical analysis supports the behavioral implications of the model for the Netherlands. Surprisingly, we do not find any evidence that the effect of commuting time on search behavior depends on the commuters' socioeconomic characteristics.
