This paper empirically studies a decentralized dynamic peer-to-peer matching market. We use data from a leading ride-sharing platform in China to estimate a continuous-time dynamic model of search and match between drivers and passengers. We assess the efficiency of the decentralized market by...

We incorporate externalities into the stable matching theory of two-sided markets. Extending the classical substitutes condition to markets with externalities, we establish that stable matchings exist when agent choices satisfy substitutability. We show that substitutability is a necessary...

Since no stable matching mechanism can induce truth-telling as a dominant strategy for all participants, there is often room in matching markets for strategic misrepresentation (Roth). In this paper we study a natural form of strategic misrepresentation: reporting a truncation of one's true...

We study matching policies in a dynamic exchange market with random compatibility, in which some agents are easier to match than others. In steady state this asymmetry creates an endogenous imbalance: hard-to-match agents wait for partners, while easy-to-match agents can match almost immediately...

We show that several classical results (the existence of a worker-optimal stable allocation, the rural hospitals theorem, the group-strategy-proofness of the worker-optimal stable mechanism) extend from the discrete to the continuous case in a generalized job matching model

I study the relationship between a matching platform's design and users' welfare. Increasing users' number of prospects has a positive choice effect (users are more likely to find a desirable partner) and a negative competition effect (users are less likely to match). The interaction of choice...

We explore the possibility of designing matching mechanisms that can accommodatenon-standard choice behavior. We pin down the necessary and sufficient conditionson participants’ choice behavior for the existence of stable and incentive compatiblemechanisms. Our results imply that...

Since no stable matching mechanism can induce truth-telling as a dominant strategy for all participants, there is often room in matching markets for strategic misrepresentation (Roth [25]). In this paper we study a natural form of strategic misrepresentation: reporting a truncation of one's true...

We consider a hybrid model at the intersection of the standard two-sided matching market as proposed by Gale and Shapley (1962) and a housing market as proposed by Shapley and Scarf (1974). Two sets of agents have to be matched in pairs to a common set of objects. Agents of one type have...

We study many-to-one matching markets in a dynamic framework with the following features: Matching is irreversible, participants exogenously join the market over time, each agent is restricted by a quota, and agents are perfectly patient. A form of strategic behavior in such markets emerges: The...
