Equilibrium Directed Search with Multiple Applications
Albrecht, James; Gautier, Pieter; Vroman, Susan - 2003
We analyse a model of equilibrium directed search in a large labour market. Each worker, observing the wages posted at all vacancies, makes a fixed, finite number of applications, a. We allow for the possibility of ex post competition should more than one vacancy want to hire the same worker....
