The political economy of enforcer liability for wrongful police stops

This article questions whether excessive policing practices can persist in an environment where law enforcement policies are subject to political pressures. Specifically, it considers a setting where the police decide whether to conduct stops based on the suspiciousness of a person's behavior and the potential liability for conducting a wrongful stop. We establish that the liability level that results in a voting equilibrium is smaller than optimal, and consequently, that excessive policing practices emerge in equilibrium.     

International students and labour market outcomes of US-born workers*

Do international students graduating from US colleges and universities affect labour market outcomes of similarly educated native-born workers? I address this question by exploiting a change in US visa policy that results in increases in the labour supply of master’s-level international students to the US labour market in science, technology, engineering and mathematics (STEM) fields. Estimates show that increases in their labour supply via temporary work permits in a certain field reduce employment of recently graduated native-born holders of a master’s degree but increase earnings of experienced native-born holders of a master’s degree in the same field. These findings support the hypothesis of substitution between skills of similarly educated immigrants and native-born individuals in the same age group and complementarity between skills of those in different age groups.
