Ridesharing platforms match drivers and riders to trips, using dynamic prices to balance
supply and demand. A challenge is to set prices that are appropriately smooth in space and …

We show how frictions and continuous transfers jointly affect equilibria in a model of
matching in trading networks. Our model incorporates distortionary frictions such as …

We develop a model of many-to-many matching with contracts that subsumes as special
cases many-to-many matching markets and buyer–seller markets with heterogeneous and …

We consider a model of matching in trading networks in which firms can enter into bilateral
contracts. In trading networks, stable outcomes, which are immune to deviations of arbitrary …

Under full substitutability of preferences, it is known that a competitive equilibrium exists in
trading networks and is equivalent to (chain) stable outcomes. In this paper, we formulate …

Various forms of substitutability are essential for establishing the existence of equilibria and
other useful properties in diverse settings such as matching, auctions, and exchange …

Several structural results for the set of competitive equilibria in trading networks with frictions
are established: The lattice theorem, the rural hospitals theorem, the existence of side …

This paper considers time exchanges via a common platform (eg, markets for exchanging
time units, positions at education institutions, and tuition waivers). There are several …

Trade has contributed to economic development and has brought countries or regions of the
world closer together, but it has also had a significant impact on the global environment …
