This study investigates how service delivery of employment-related federal programs administered at American Job Centers (AJCs) changes as local unemployment increases. The authors analyze the impact of such changes on labor market outcomes of program participants using data for the Trade Adjustment Assistance (TAA) participants. The authors find that the demand for TAA services increases substantially when local unemployment increases. A 5% to 10% increase in unemployment raises training enrollment through the TAA program by nearly 13 percentage points and increases participation duration by more than 9 weeks. Our results do not support the concern that a sudden rise in the demand for AJC services might deteriorate the quality of service delivery and outcomes. In fact, although increases in local unemployment are generally harmful to displaced workers, occupational training during this time is effective at reducing the size of wage loss by at least 46%, resulting in a 3.4% average increase for wage replacement rates.
