Job Vacancies and Immigration: Evidence from the Mariel Supply Shock

L. Jason Anastasopoulos,  George J. Borjas, Gavin G. Cook, and Michael Lachanski

We use the Conference Board's Help-Wanted Index (HWI) to document how immigrant supply shocks change the number of job vacancies.  Our analysis reveals a sizable drop in Miami's HWI relative to comparable cities in the first few years after the Mariel shock, followed by recovery afterwards.  An analysis of the text of the help-wanted ads also documents a significant decline in the relative number of low-skill vaccancies advertised in the Miami Herald.  Miami's Beveridge curve shifted inwards by the mid-1980s, suggesting a more efficient local labor market, in contrast to the outward nationwide shift coincident with the 1981-1982 recession.


The Center for Causal Inference (CCI) is a research center that is operating under a partnership between Penn’s Center for Clinical Epidemiology and Biostatistics (CCEB), the Department of Biostatistics and Epidemiology, Rutgers School of Public Health, and Penn’s Wharton School. The mission of the CCI is to be a leading center for research and training in the development and application of causal inference theory and methods.
