Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the causes and welfare consequences of unravelling in two-sided matching markets. It shows that similarity of preferences is an important factor driving unravelling. In particular, it shows that under the ex-post stable mechanism (the mechanism that the literature focuses on), unravelling is more likely to occur when participants have more similar preferences. It also shows that any Pareto-optimal mechanism must prevent unravelling, and that the ex-post stable mechanism is Pareto-optimal if and only if it prevents unravelling.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the design and implementation of matching markets where transfers are not available, such as college admissions, school choice, and certain labor markets. The results contribute to the literature from both a theoretical and a behavioral perspective, and may have policy implications for the design of some real-life matching markets. Chapter 1, “Exploding Offers and Unraveling in Two-Sided Matching Markets,” studies the unraveling problem prevalent in many two-sided matching markets that occurs when transactions become inefficiently early. In a two-period decentralized model, I examine whether the use of exploding offers can affect agents' early moving incentives. The results show that when the culture of the market allows firms to make exploding offers, unraveling is more likely to occur, leading to a less socially desirable matching outcome. A market with an excess supply of labor is less vulnerable to the presence of exploding offers; yet the conclusion is ambiguous for a market with a greater degree of uncertainty in early stages, which depends on the specific information structure. While a policy banning exploding offers tends to be supported by high quality firms and workers, it can be opposed by those of lower quality. This explains the prevalence of exploding offers in practice. Chapter 2, “Constrained School Choice and Information Acquisition,” investigates a common practice of many school choice programs in the field, where the length of students' submitted preference lists are constrained. In an environment where students have incomplete information about others’ preferences, I theoretically study the effect of such a constraint under both a Deferred Acceptance mechanism (DA) and a Boston mechanism (BOS). The result shows that ex-ante stability can only be ensured under an unconstrained DA, but not under a constrained DA, an unconstrained BOS, or a constrained BOS. In a lab experiment, I find that the constraint also affects students’ information acquisition behavior. Specifically, when faced with a constraint, students tend to acquire less wasteful information and distribute more efforts to acquire relevant information under DA; such an effect is not significant under BOS. Overall, the constraint has a negative effect on efficiency and stability under both mechanisms. Chapter 3, “Targeted Advertising on Competing Platforms,” is jointly written with Huanxing Yang. We investigate targeted advertising in two-sided markets. Each of the two competing platforms has single-homing consumers on one side and multi-homing advertising firms on the other. We focus on how asymmetry in platforms’ targeting abilities translates into asymmetric equilibrium outcomes, and how changes in targeting ability affect the price and volume of ads, consumer welfare, and advertising firms' profits. We also compare social incentives and equilibrium incentives in investing in targeting ability. Chapter 4, “The Instability of Matching with Overconfident Agents: Laboratory and Field Investigations,” focuses on centralized college admissions markets where students are evaluated and allocated based on their performance on a standardized exam. A single exam’s measurement error causes the exam-based priorities to deviate from colleges' aptitude-based preferences: a student who underperforms in one exam may lose her placement at a preferred college to someone with a lower aptitude. The previous literature proposes a solution of combining a Boston algorithm with pre-exam preference submission. Under the assumption that students have perfect knowledge of their relative aptitudes before taking the exam, the suggested mechanism intends to trigger a self-sorting process, with students of higher (lower) aptitudes targeting more (less) preferred colleges. However, in a laboratory experiment, I find that such a self-sorting process is skewed by overconfidence, which leads to a welfare loss larger than the purported benefits. Moreover, the mechanism introduces unfairness by rewarding overconfidence and punishing underconfidence, thus serving as a gender penalty for women. I also analyze field data from Chinese high schools; the results suggest similar conclusions as in the lab.

This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We study an experiment of the students-proposing deferred acceptance mechanism (DA) in matching markets where firms are matched with students. We investigated the two different situations: (i) Students know firms' preferences and firms submit their true preference, (ii) Students know firms' preferences and firms submit a higher ranking to students who give them higher ranking. This experiment confirms that the matching results under DA in uence students' preference formation, which decreases the degree of stability. If firms do not submit their true preferences, students also do not submit their true preferences. As a result, the situation induces instability. Moreover, we find the new pattern of submitted preferences - compromise strategy. If there is an extreme option, students will tend to prefer the in-between option.

Book excerpt: We study how to reduce congestion in two-sided matching markets with private preferences. We measure congestion by the number of bits of information that agents must (i) learn about their own preferences, and (ii) communicate with others before obtaining their final match. Previous results by Segal (2007) and Gonczarowski et al. (2015) suggest that a high level of congestion is inevitable under arbitrary preferences before the market can clear with a stable matching. We show that when the unobservable component of agent preferences satisfies certain natural assumptions, it is possible to recommend potential matches and encourage informative signals such that the market reaches a stable matching with a low level of congestion. This is desirable because the communication overhead is minimized while agents have negligible incentives to leave the marketplace or to look beyond the set of recommended partners. The main idea is to only recommend partners with whom the agent has a non-negligible chance of both liking and being liked by. The recommendations are based both on the observable component of preferences, and on the signals sent by agents on the other side that indicate interest.

Download or read book Matching Markets with Correlated Preferences written by Onur Celik and published by LAP Lambert Academic Publishing. This book was released on 2010-04 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this dissertation is to explore, via simulations, the effect of correlation in the preference lists on the aggregate satisfaction of the participants in the marriage matching model and the roommates problem. In the first chapter, a general methodology is presented to introduce correlation in the preference lists that can be used in any kind of matching market. The second chapter focuses on the simplest two-sided and one-to-one matching market, that is, a marriage matching model, using the men-propose Gale and Shapley algorithm. The third chapter focuses on a one-sided matching market, namely the roommates problem, using the extended version of the Gale and Shapley algorithm. For each of the matching markets in question, a measure to quantify the level of the correlation is also provided which enables us to sort the preference profiles according to their correlation levels and makes it possible to do statistical analysis.Results show that the correlation is an important factor that affects the aggregate satisfaction levels of the participants.

Available in PDF, EPUB and Kindle. Book excerpt: We study estimation and non-parametric identification of preferences in two-sided matching markets using data from a single market with many agents. We consider a model in which preferences of each side of the market are vertical, utility is non-transferable and the observed matches are pairwise stable. We show that preferences are not identified with data on one-to-one matches but are non-parametrically identified when data from many-to-one matches are observed. The additional empirical content in many-to-one matches is illustrated by comparing two simulated objective functions, one that does and the other that does not use information available in many-to-one matching. We also prove consistency of a method of moments estimator for a parametric model under a data generating process in which the size of the matching market increases, but data only on one market is observed. Since matches in a single market are interdependent, our proof of consistency cannot rely on observations of independent matches. Finally, we present Monte Carlo studies of a simulation based estimator.

Download or read book Studies of Labor Market Intermediation written by David H. Autor and published by University of Chicago Press. This book was released on 2009-12-15 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the traditional craft hiring hall to the Web site Monster.com, a multitude of institutions exist to facilitate the matching of workers with firms. The diversity of such Labor Market Intermediaries (LMIs) encompasses criminal records providers, public employment offices, labor unions, temporary help agencies, and centralized medical residency matches. Studies of Labor Market Intermediation analyzes how these third-party actors intercede where workers and firms meet, thereby aiding, impeding, and, in some cases, exploiting the matching process. By building a conceptual foundation for analyzing the roles that these understudied economic actors serve in the labor market, this volume develops both a qualitative and quantitative sense of their significance to market operation and worker welfare. Cross-national in scope, Studies of Labor Market Intermediation is distinctive in coalescing research on a set of market institutions that are typically treated as isolated entities, thus setting a research agenda for analyzing the changing shape of employment in an era of rapid globalization and technological change.

This book was released on 2011 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: I explore fundamental behavioral aspects of several market design environments in a variety of projects using both theoretical models and laboratory experiments. I show that human tendencies can drastically shift potential outcomes away from those which would result if individuals were fully 'rational' and unbiased in decision problems similar to those found frequently in the field. I explore two common classes of centralized matching mechanisms--Deferred Acceptance and Priority--which have wildly different success rates in practice despite both being open to manipulation by agents who have incomplete information about the other participants in the match. For this reason, theory predicts both mechanisms in equilibrium will yield match outcomes which are unstable, meaning some agents will desire to renegotiate with one another after receiving their match assignments, and thus reduce participants' confidence in using the match. I provide laboratory evidence that out-of-equilibrium truth telling by agents is substantially more frequent in the Deferred Acceptance environment and thus Deferred Acceptance matches will generally be more stable in practice than matches using a Priority mechanism. This may explain why Deferred Acceptance mechanisms appear to be more viable in the field. I also explore two different models of decentralized two-sided matching environments where establishing scarce signaling methods can improve market outcomes. In a laboratory experiment, I show that allowing potential receiving job offers to send a single signal to their favorite potential employer before job offers are made increases overall match rates in the market, but is potentially damaging to the firms making offers when compared to the market without such a signal. Then, in a theoretical model where pre-offer communication takes the form of an interview process where workers have natural limits on the number of interviews in which they can participate, I show that in many cases firms can benefit themselves and the market as a whole by voluntarily restricting the number of interviews they offer to participate in. While not traditionally thought of as market design problems, voting mechanisms are fundamentally goods allocation problems as well and have many of the same issues as traditional markets do. I explore the effects of voter bias on outcomes in an otherwise standard voting model and find that even slight external pressure on individuals in a committee tasked with coming to a collective decision can destroy the ability of that committee to arrive at the correct result, even when individuals have good information about the best decision to make. Furthermore, the quality of the decision made by such a committee can actually degrade as the committee size increases, in contrast with the canonical Condorcet Jury Theorem which predicts that a committee's ability to choose the right outcome increases quickly as more members are added.

Available in PDF, EPUB and Kindle. Book excerpt: This paper develops a price-theoretic framework for matching markets with heterogeneous preferences. The model departs from the standard Gale and Shapley (1962) model by assuming that a finite number of agents on one side (colleges or firms) are matched to a continuum mass of agents on the other side (students or workers). We show that stable matchings correspond to solutions of supply and demand equations, with the selectivity of each college playing a role similar to prices.We apply the model to an analysis of how competition induced by school choice gives schools incentives to invest in different aspects of quality. As another application, we characterize the asymptotics of school choice mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this Handbook is twofold: to educate and to inspire. It is meant for researchers and graduate students who are interested in taking a data-based and behavioral approach to the study of game theory. Educators and students of economics will find the Handbook useful as a companion book to conventional upper-level game theory textbooks, enabling them to compare and contrast actual behavior with theoretical predictions. Researchers and non-specialists will find valuable examples of laboratory and field experiments that test game theoretic propositions and suggest new ways of modeling strategic behavior. Chapters are organized into several sections; each section concludes with an inspirational chapter, offering suggestions on new directions and cutting-edge topics of research in experimental game theory.

Download or read book Models of Matching Markets written by Sangram Vilasrao Kadam and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The structure, length, and characteristics of matching markets affect the outcomes for their participants. This dissertation attempts to fill the lacuna in our understanding about matching markets on three dimensions through three essays. The first essay highlights the role of constraints at the interviewing stage of matching markets where participants have to make choices even before they discover their own preferences entirely. Two results stand out from this setting. When preferences are ex-ante aligned, relaxing the interviewing constraints for one side of the market improves the welfare for everyone on the other side. Moreover, such interventions can lead to a decrease in the number of matched agents. The second essay elucidates the importance of rematching opportunities when relationships last over multiple periods. It identifies sufficient conditions for existence of a stable matching which accommodates the form of preferences we expect to see in multi-period environments. Preferences with inter-temporal complementarities, desire for variety and a status-quo bias are included in this setting. The third essay furthers our understanding while connecting two of the sufficient conditions in a specialized matching with contracts setting. It provides a novel linkage by providing a constructive way of arriving at a preference condition starting from another and thus proving that the later implies the former.
