6. Conclusion
In a simple model describing the interview process for professional labor markets, we have pointed out that inefficient unemployment may result if screening is costly and firms compete for workers. This occurs when applicants' types are private information and firms decide not to interview an applicant who was previously interviewed by a more productive firm. This could cause able applicants to go unemployed and productive vacancies to go unfilled. This effect applies to other markets as well, such as the housing market and credit market. Our work suggests several directions for future research. First, changing the setting to allow for strategic wage setting and idiosyncratic preferences among firms and applicants are natural extensions. Second, analyzing interview markets for non-entry level applicants poses interesting challenges. Third, it would be of interest to understand how applicants match with firms given the inefficiencies explored in the paper, potentially in a framework with directed search.
