Using staggered entry of two dockless bike‐sharing firms, we study whether the entrant
expands or steals the market from the incumbent in 59 cities. Compared with 23 cities …

We explore efficiency and optimal policy in decentralized transport markets, such as taxis,
trucks, and bulk shipping. We show that in these markets, search frictions distort the …

This paper studies the effects of economies of density in transportation markets, focusing on
ridesharing. Our theoretical model predicts that (i) economies of density skew the supply of …

Workers in developing countries waste significant time commuting, and gaps in public transit
constrain access to productive jobs. In many cities, privately-operated minibuses provide 50 …

A recent empirical literature models search and matching frictions by means of a reduced-
