6. Concluding remarks
The literature on the theoretical analysis of firms' search behaviors is relatively scarce. To contribute towards this gap, I employ a discrete time infinite horizon model with homogeneous workers and firms and match specific output. The quality of an employment relationship between a firm and a worker (match) can be either good or bad. Good matches produce a higher output, while bad matches are undesirable. The true quality of the match is unknown before the employment relationship starts and it is revealed after the parties observe the output. Unemployed workers apply to all vacancy posts and firms pick the number of workers to conduct interviews with, incurring some cost. An interview reveals the probability of the worker being a good match for the firm. Firms choose the number of interviews to maximize the value of their vacancy and select the worker with the highest probability of the match quality being good among workers interviewed. A firm's choice of interviews depends on the productivity gap between a good and a bad match output, the cost of the interview, the probability of a match in the subsequent periods, the cutoff rule for an acceptable match, as well as the distribution that governs the probability of a match quality being good.
