چکیده

A market consists of buyers and sellers of some commodity, say a DVD movie. In this thesis, we assume the role of market operator. Our goal is to ensure that the market has certain desirable properties, including truthfulness, fairness and stability. We explore how to achieve these properties by designing rules for how the participants (buyers and sellers) can interact. We also explore how to efficiently compute the outcome of large numbers of participants interacting at once. The main type of market we study is called a matching market. We study several particular matching markets, including keyword auction, kidney exchange and stable roommate markets. In each of these cases, the aim is to match the participants to each other, somehow taking into account their preferences for one another. Our results focus on properties of the matching process and the design of efficient algorithms for finding various types of matchings. In particular, we present new polynomial time algorithms for finding matchings that have one of the following properties: popularity, rank-maximality and fairness. We also give an efficient algorithm for clearing large swap markets such as kidney exchanges. Finally, we present a new decomposition technique for designing keyword auctions.

Recent Developments in Matching Theory and Its Practical Applications

In recent years, many developments have been made in matching theory and its applications to market design. This paper surveys them and suggests possible research directions. The main focus is on the advances in matching theory that try to solve market design problems in practical markets where the classic theory is inapplicable. Specifically, we discuss the recent theory of matching in large m...

Design and Implementation of a Scalable Fuzzy Case-Based Matching Engine

We discuss the design and the implementation of a flexible and scalable fuzzy case-based matching engine. The engine’s flexible design is illustrated for two of its core components: the internal representation of cases by means of a variety of crisp and fuzzy data types, and the fuzzy operations to execute the ensuing case matching process. We investigate the scalability of the matching engine ...

Contract Design and Stability in Matching Markets

We develop a model of many-to-many matching with contracts which subsumes as special cases many-to-many matching markets and buyer-seller markets with heterogeneous and indivisible goods. In our setting, in contrast to results for the setting of many-to-one matching with contracts, preference substitutability is sufficient and necessary to guarantee the existence of a nonempty lattice of stable...

Matching Plans for Agents with Vertically and Horizontally Differentiated Preferences∗

We develop a location model of price discrimination in many-to-many matching markets in which agents’ preferences are both vertically and horizontally differentiated. The optimal plans induce negative assortative matching at the margin: at any given location, agents with a low value for interacting with agents from the opposite side (the vertical dimension) are included in the matching sets of ...

Cross-Subsidization and Matching Design∗

We develop a theory of price discrimination in many-to-many matching markets in which agents’ preferences are vertically and horizontally differentiated. The optimal plans induce negative assortative matching at the margin: agents with a low value for interacting with other agents are included in the matching sets of only those agents from the opposite side whose value for matching is sufficien...
