|December 2019||Firm and Worker Dynamics in a Frictional Labor Market|
with , , : w26547
This paper develops a random-matching model of a frictional labor market with firm and worker dynamics. Multi-worker firms choose whether to shrink or expand their employment in response to shocks to their decreasing returns to scale technology. Growing entails posting costly vacancies, which are filled either by the unemployed or by employees poached from other firms. Firms also choose when to enter and exit the market. Tractability is obtained by proving that, under a parsimonious set of assumptions, all workers’ and firm decisions are characterized by their joint marginal surplus, which in turn only depends on the firm’s productivity and size. As frictions vanish, the model converges to a standard competitive model of firm dynamics which allows a quantification of the misallocation cost...

with : w24867
The location of individuals determines their job opportunities, living amenities, and housing costs. We argue that it is useful to conceptualize the location choice of individuals as a decision to invest in a ‘location asset.’ This asset has a cost equal to the location's rent, and a payoff through better job opportunities and, potentially, more human capital for the individual and her children. As with any asset, savers in the location asset transfer resources into the future by going to expensive locations with good future opportunities. In contrast, borrowers transfer resources to the present by going to cheap locations that offer few other advantages. As in a standard portfolio problem, holdings of this asset depend on the comparison of its rate of return with that of other assets. Dif...
