We document gender differences in the price paid for work-related air travel among similar workers within a firm. We show that women pay consistently less per ticket than men, after accounting for a large set of covariates that include the characteristics of the trips, the employers, and the...

We document gender differences in the behavior of similar workers within a firm when they book business air travel. We show that women pay consistently less per ticket than men, after accounting for a large set of covariates that include the characteristics of the traveler, the routes and class...

This paper uses networks to study price dispersion in seller-buyer markets where buyers with unit demand interact with multiple, but not all, sellers; and buyers and sellers compete on prices after they meet. The central finding of this paper is that price dispersion is determined by the...

This paper models frictions in buyer-seller markets using networks, where buyers are linked with a subset of sellers and sellers are linked with a subset of buyers. Sparser networks are associated with higher search frictions. We use the model to characterize pairwise stable allocations and...

Peters and Severinov (2006) (PS henceforth) characterize a perfect Bayesian equilibrium (PBE) in a competing auctions environment, where all buyers are linked to all the sellers. PS characterize a PBE using a simple bidding rule, whereby buyers select in which auction to bid. In this note we...

This paper studies price dispersion in buyer-seller markets using networks to model frictions, where buyers are linked with a subset of sellers and sellers are linked with a subset of buyers. Although there is a large search literature studying wage/price dispersion, search models typically...

This paper uses networks to study price dispersion in seller-buyer markets where buyers with unit demand interact with multiple, but not all, sellers; and buyers and sellers compete on prices after they meet. Our approach allows for ex post indirect competition, where a buyer who is not directly...

This paper analyze the demand for educational services in a context in which households and schools are heterogeneous. Distance from student’s place of residence to schools is a key component of our model. School quality and household characteristics are also important in- gredients. Our...
