Beginning in 1951, the Conference Board constructed a monthly job vacancy index by counting the number of help-wanted ads published in local newspapers in 51 metropolitan areas. We use the Help-Wanted Index (HWI) to document how immigration changes the number of job vacancies in the affected labor markets. Our analysis revisits the Mariel episode. The data reveal a marked drop in Miami’s HWI relative to many alternative control groups in the first 4 or 5 years after Mariel, followed by recovery afterwards. The Miami evidence is consistent with the observed relation between immigration and the HWI across all metropolitan areas in the 1970-2000 period: these spatial correlations suggest that more immigration reduces the number of job vacancies. We also explore some of the macro implications ...
