In mechanism design, Myerson regularity is often too weak for a quantitative analysis of performance. For instance, ratios between revenue and welfare, or sales probabilities may vanish at the boundary of Myerson regularity. This paper therefore explores the quantitative version of Myerson...

In many markets, sellers advertise their good with an asking price. This is a price at which the seller is willing to take his good off the market and trade immediately, though it is understood that a buyer can submit an offer below the asking price and that this offer may be accepted if the...

We investigate the formation of market prices in a new experimental setting involving multi-period call-auction asset markets with state-dependent fundamentals. We are particularly interested in two informational aspects: (1) the role of traders who are informed about the true state and/or (2)...

This paper studies sequential social learning when people learn about others' actions through coarse signals. Agents arrive in cohorts sequentially. Each agent chooses an action upon observing a private "state-signal'' about a payoff-relevant state of the world and "action-signals'' that...

This paper studies the menu of licenses designed by the child welfare agency to screen foster parents. We develop a two-sided matching model with heterogeneous agents, search frictions, private information, and a designer who coordinates match formation through a menu of contracts. We focus on...

Digital platforms, empowered by artificial intelligence algorithms, facilitate efficient interactions between consumers and merchants that allow the collection of profiling information which drives innovation and welfare. Private incentives, however, lead to information asymmetries resulting in...

This paper studies the impact of size-discovery trading protocols on allocative efficiency in markets with discrete trading. I use a dynamic-discrete-trading model with imperfect competition that sequentially offers a size or price-discovery trading session. The frequency at which trade occurs...

In this paper, the interactions between a large informed trader (IT, for short) and a high-frequency trader (HFT, for short) who can anticipate the former's incoming order are studied in an extended Kyle's model. Equilibria under various specific situations are discussed. We find that, in...

We develop a principal/agent model for matching agents in two-sided assignments. A principal has preferences over all agents' assignments, and agents have privately-known preferences about their own match (but are indifferent about others'). Unhappy agents can quit, but the principal can stop...

We consider the problem of allocating a single object to the agents with payments. Agents have preferences that are not necessarily quasi-linear. We characterize the class of rules satisfying pairwise strategy-proofness and non-imposition by the priority rule. Our characterization result remains...
