We investigate the causal effects of financial incentives supporting geographical mobility among unemployed workers on their job search behavior and labor market outcomes. Exploiting regional variation in the promotion of mobility programs along administrative borders of German employment agency districts, we show that promoting mobility—as intended—causes job seekers to increase their search radius, apply for, and accept distant jobs. At the same time, local job search is reduced with adverse consequences for reemployment and earnings. A detailed analysis of the underlying mechanisms suggests spatial search frictions as the driver of the unintended adverse labor market effects.

Standard job search theory assumes that unemployed individuals have perfect information about the effect of their search effort on the job offer arrival rate. We present an alternative model that assumes that each individual has a subjective belief about the impact of her search effort on the job arrival. These beliefs depend in part on an individual's locus of control. We estimate the impact of locus of control on job search behavior using a data set of newly unemployed individuals in Germany. Consistent with our theoretical predictions, we find evidence that individuals with an internal locus of control search more and that individuals who believe that their future outcomes are determined by external factors have lower reservation wages.
