This dissertation consists of two essays on two-sided matching. In chapter 2, we consider a model of intermediation wherein an incumbent matchmaker faces the threat of entry from a potential entrant. We model this competition as an entry game where the incumbent moves first and offers a contract to a subset of men and women. The entrant observes the actions of the incumbent and then decides to enter or stay out. If there is entry, then the entrant offers a contract targeted to a subset of men and women. When thepayoff from matching is complementary in the types of the agents, we prove that there exists a weak sequential equilibrium either withentry and market segmentation or with entry deterrence. Our model explains the strategic market differentiation by the firms as thecreation of a niche market for themselves. The data on the presence of niche dating websites confirms this result.^An important findingof our model is that at an equilibrium, each firm offers a different contract to the men and women that they match. In sharp contrast toexisting models in the Industrial Organization literature on entry deterrence, we find that accommodating the entrant is anoptimal strategy for the incumbent, not entry deterrence. We then compare the duopoly market with a two-price monopoly market and findthat the duopoly market has greater coverage than a two-price monopoly market. The model is then extended to allow for sequentialentry. When intermediation is costless, allowing for sequential entry yields the socially efficient outcome as the number of entrants tends to infinity. Introducing intermediation costs leadsto a welfare loss and a finite number of intermediaries entering. In chapter 3, we extend the model developed in chapter 2 by introducing search in a model of intermediation.^It is common thatmen and women also search by themselves for a suitable partner in addition to using the services of the intermediaries. The entry gameis modified by allowing for the possibility that the men and women can search in the decentralized market. The men and women comparethe expected value of accepting the match offered by the intermediaries to the expected value of search in the decentralizedmarket. We prove that there exists a weak sequential equilibrium where the incumbent offers a contract to a subset consisting of thehighest types of men and women, the entrant enters and offers a contract to a subset of the highest types remaining in the residualmarket and the men and women not offered any contract by either the incumbent or the entrant search in the decentralized market using areservation value strategy.^Thus in addition to incorporating search in a model of intermediation, our model proves that marketsegmentation arises due to competition between the intermediaries to create a niche market for themselves. An interesting finding is thatthe higher types of agents prefer using the services of intermediaries while the lower types search by themselves. We thendiscuss the issues of entry accommodation and entry deterrence and find that strategic entry accommodation is the optimal strategy for the entrant, not entry deterrence. Thereafter we compare the duopoly model with a two-price monopoly market to ascertain whether the duopoly market has a greater coverage than a two-price monopoly market. Unlike in chapter 2, wedo not get a direct answer. Coverage could be higher in either of the two markets. However, as the value of search in the decentralized market decreases (and in the limit reaches zero), theduopoly market has greater coverage than a two-price monopoly market.^Finally we extend the model to allow for sequential entry. When intermediation is costless we find that the number of entrants tends to infinity and that matching is socially efficient. Howeverintroducing intermediation costs distorts this efficiency result and only a finite number of intermediaries enter the market.

This paper studies a two-sided matching market with intermediation where an incumbent match-maker faces the threat of entry from a potential entrant. When the payoff from matching is complementary in the types of the agents there exists a weak sequential equilibrium, either with entry and market segmentation or with entry deterrence. If the market is large enough, then strategic entry accommodation is the optimal strategy for the incumbent, not entry deterrence. The duopoly market has greater coverage than a two-price monopoly market. When intermediation is costless, allowing for sequential entry yields the socially efficient outcome as the number of entrants tends to infinity. Introducing intermediation costs leads to a welfare loss.

There is more statistical data produced in today’s modern society than ever before. This data is analysed and cross-referenced for innumerable reasons. However, many data sets have no shared element and are harder to combine and therefore obtain any meaningful inference from. Statistical matching allows just that; it is the art of combining information from different sources (particularly sample surveys) that contain no common unit. In response to modern influxes of data, it is an area of rapidly growing interest and complexity. Statistical Matching: Theory and Practice introduces the basics of statistical matching, before going on to offer a detailed, up-to-date overview of the methods used and an examination of their practical applications. Presents a unified framework for both theoretical and practical aspects of statistical matching. Provides a detailed description covering all the steps needed to perform statistical matching. Contains a critical overview of the available statistical matching methods. Discusses all the major issues in detail, such as the Conditional Independence Assumption and the assessment of uncertainty. Includes numerous examples and applications, enabling the reader to apply the methods in their own work. Features an appendix detailing algorithms written in the R language. Statistical Matching: Theory and Practice presents a comprehensive exploration of an increasingly important area. Ideal for researchers in national statistics institutes and applied statisticians, it will also prove to be an invaluable text for scientists and researchers from all disciplines engaged in the multivariate analysis of data collected from different sources.
