I provide a brief introduction to the early literatures on Matching, Auctions, and Market Design.The design of matching markets and auctions has brought economic theory and practice together. Indeed, this is an area where microeconomic theory has had its largest direct impact. This is in part...

We explain how the common practice of size-discovery trade detracts from overallfinancial market efficiency. At each of a series of size-discovery sessions, traders report theirdesired trades, generating allocations of the asset and cash that rely on the most recent exchangeprice. Traders can...

Size-discovery mechanisms allow large quantities of an asset to be exchanged at a price that does not respond to price pressure. Primary examples include ``workup'' in Treasury markets, ``matching sessions'' in corporate bond and CDS markets, and block-trading ``dark pools'' in equity markets....

Two-sided matching platforms can control and optimize over many aspects of the search for partners. To understand how matching platforms should be designed, we introduce a dynamic two-sided search model with strategic agents who must bear a cost to discover their value for each potential...

This Handbook chapter seeks to introduce students and researchers of industrial organization (IO) to the field of market design. We emphasize two important points of connection between the IO and market design fields: a focus on market failures—both understanding sources of market failure and...

Mechanisms used to derive optimal allocations are generally designed under the premise that agents fully know their preferences. It is often impossible to duplicate these optimal allocations when agents imperfectly observe object characteristics. I present a crowdsourcing mechanism to...

We explore the possibility of designing matching mechanisms that can accommodate non-standard choice behavior. We pin down the necessary and sufficient conditions on participants’ choice behavior for the existence of stable and incentive compatible mechanisms. Our results imply that...

This paper examines the relationship between ethics and market design. It argues that market design should not rely wholly on preference utilitarianism in order to make ethical judgements. It exposits an alternative normative framework — informed neutrality between reasonable ethical positions

In a market in which sellers compete for heterogeneous buyers by posting mechanisms, we analyze how the properties of the meeting technology affect the allocation of buyers to sellers. We show that a separate submarket for each type of buyer is the efficient outcome if and only if meetings are...
