This study sought to determine how the length of time out of work affects a worker's job market opportunities. This was done using a large-scale resume audit study, in which fictitious resumes were submitted to real, online job postings in each of the 100 largest metropolitan areas (MSAs) in the U.S., and "callbacks" from employers were tracked for each submission. For each resume, both the employment status and the length of the current unemployment spell were randomized from 1 to 36 months (if the worker is unemployed). The study was conducted in a single major online job board in the U.S. focusing on three job categories: administrative/clerical, customer service, and sales. Within these job categories, roughly 12,000 fictitious resumes were sent to roughly 3,000 job openings located in the largest 100 Metropolitan Statistical Areas in the U.S. according to population. In choosing a job to apply to, MSA and job category combinations were randomly sampled without replacement from the distribution. Upon being assigned an MSA and job category, jobs were sought out within the pre-determined MSA for the pre-determined job type. Once a job was identified, four fictitious resumes were constructed and sent to the job opening. The design of these resumes was based on roughly 1,200 real resumes that were manually collected from various online job message boards.
