英文摘要：
We discuss the distribution of commuting distances and its relation to income. Using data from Denmark, the UK, and the US, we show that the commuting distance is (i) broadly distributed with a slow decaying tail that can be fitted by a power law with exponent $\\gamma \\approx 3$ and (ii) an average growing slowly as a power law with an exponent less than one that depends on the country considered. The classical theory for job search is based on the idea that workers evaluate the wage of potential jobs as they arrive sequentially through time, and extending this model with space, we obtain predictions that are strongly contradicted by our empirical findings. We propose an alternative model that is based on the idea that workers evaluate potential jobs based on a quality aspect and that workers search for jobs sequentially across space. We also assume that the density of potential jobs depends on the skills of the worker and decreases with the wage. The predicted distribution of commuting distances decays as $1/r^{3}$ and is independent of the distribution of the quality of jobs. We find our alternative model to be in agreement with our data. This type of approach opens new perspectives for the modeling of mobility.

中文摘要：
我们讨论通勤距离的分布及其与收入的关系。利用丹麦、英国和美国的数据，我们发现通勤距离（i）分布广泛，具有缓慢衰减的尾部，可以用指数$\\gamma\\约为3$的幂律拟合；（ii）平均增长缓慢，指数小于1的幂律，取决于所考虑的国家。求职的经典理论基于这样一种观点，即工人在潜在工作的工资随时间顺序到达时对其进行评估，并将该模型扩展到空间，我们得到的预测与我们的实证结果强烈矛盾。我们提出了一个替代模型，该模型基于这样一个理念，即工人基于质量方面评估潜在工作，并且工人在空间中顺序搜索工作。我们还假设潜在工作的密度取决于工人的技能，并随着工资的增加而降低。通勤距离的预测分布衰减为$1/r^{3}$，与工作质量的分布无关。我们发现我们的替代模型与我们的数据一致。这种方法为移动性建模开辟了新的视角。
