摘要：We develop a model where workers, anticipating the risk of becoming unemployed, invest in connections in order to access information about available jobs that other workers may have. The investment in connections is high when the job separation rate in the labor market is moderate, whereas it is low for either low or high levels of job separation rate. The equilibrium response of network investment to changes in the labor market conditions generates novel empirical predictions. In particular, ...

摘要：I study a directed search model of oligopolistic competition, extended to incorporate general capacity constraints, congestion effects, and pricing based on ex post demand. In the presence of any one of these ingredients, the Bertrand paradox fails to hold. Hence, despite the emphasis that has been placed by the literature on sellers' capacity constraints as a resolution to the paradox, the existence of such constraints is only a subcase of a general class of environments where the paradox fai...

摘要：This article studies repeated entry and bidding decisions in construction procurement auctions. I find evidence in the data that suggests the presence of significant cost savings from entering contracts of the same type. I estimate a dynamic auction model to measure the gains to experience for bidders. I allow for endogenous entry, synergies in entry, and unobserved auction heterogeneity. I find that a bidder can halve entry costs by focusing on specific contract types. An auctioneer can incre...
