Abstract: We present a dynamic model of the labor market, where workers may commit crimes and employers can gather information about workers’ criminal history from a publicly available record and set wages accordingly. We characterize the socially optimal duration of the record, which balances two conflicting objectives: deter inefficient crimes for workers without a record and keep the share of the population with a record low to reduce recidivism. We also show that, when the social harm from crime is neither too high nor too low, it is optimal to impose finite nonmonetary sanctions followed by a finite criminal-record period.

Abstract: This study examines how college capacity constraints affect private tutoring demand. Exploiting the quasi-experimental variation of the 1995 deregulation that lifted enrollment caps on local colleges while maintaining Seoul college restrictions, we build a two-sided equilibrium model where colleges choose seat allocations and students compete through tutoring investment. Counterfactual simulations suggest nationwide deregulation would decrease overall tutoring rates by 50%, from 38.6% to 20.0%.
