The Theory of Industrial Organization

Praise for the Third Edition: "This is one of the best books available. Its excellent organizational structure allows quick reference to specific models and its clear presentation . . . solidifies the understanding of the concepts being presented."IIE Transactions on Operations EngineeringThoroughly revised and expanded to reflect the latest developments in the field, Fundamentals of Queueing Theory, Fourth Edition continues to present the basic statistical principles that are necessary to analyze the probabilistic nature of queues. Rather than presenting a narrow focus on the subject, this update illustrates the wide-reaching, fundamental concepts in queueing theory and its applications to diverse areas such as computer science, engineering, business, and operations research.This update takes a numerical approach to understanding and making probable estimations relating to queues, with a comprehensive outline of simple and more advanced queueing models. Newly featured topics of the Fourth Edition include:Retrial queuesApproximations for queueing networksNumerical inversion of transformsDetermining the appropriate number of servers to balance quality and cost of serviceEach chapter provides a self-contained presentation of key concepts and formulae, allowing readers to work with each section independently, while a summary table at the end of the book outlines the types of queues that have been discussed and their results. In addition, two new appendices have been added, discussing transforms and generating functions as well as the fundamentals of differential and difference equations. New examples are now included along with problems that incorporate QtsPlus software, which is freely available via the book's related Web site.With its accessible style and wealth of real-world examples, Fundamentals of Queueing Theory, Fourth Edition is an ideal book for courses on queueing theory at the upper-undergraduate and graduate levels. It is also a valuable resource for researchers and practitioners who analyze congestion in the fields of telecommunications, transportation, aviation, and management science.

Earnings Management and Investor Protection: An International Comparison

Learning by observing the past decisions of others can help explain some otherwise puzzling phenomena about human behavior. For example, why do people tend to converge on similar behavior? Why is mass behavior prone to error and fads? The authors argue that the theory of observational learning, and particularly of informational cascades, has much to offer economics, business strategy, political science, and the study of criminal behavior.

We explore the optimal disclosure policy of a certification intermediary in an environment where (i) the seller's decision on entry and investment in product quality are endogenous and (ii) the buyers observe an additional public signal on quality. The intermediary mutes the seller's entry incentives but enhances investment incentives following entry, and the optimal policy maximizes rent extraction from the seller in the face of this trade-off. We identify conditions under which full, partial or no disclosure can be optimal. The intermediary's report becomes noisier as the public signal gets more precise, but if the public signal becomes too precise, the intermediary resorts to full disclosure. In the presence of an intermediary, a more precise public signal may also lead to lower social welfare.

Optimal certification policy, entry, and investment in the presence of public signals

This paper provides a simple model of corruption dynamics with the ratchet effect. As in Shleifer and Vishny [1993], we consider the sale of government property (entry permit) by government officials as the prototype of corruption activities. In a dynamic version of the Shleifer-Vishny model, corrupt officials have ex post the incentive to price discriminate entrepreneurs based on the entry decisions made in an earlier period. We show that the inability of government officials to commit to future money demands induces the ratchet effect in that entrepreneurs have incentives to delay entry in order to receive a discount in the permit price later. The ex post opportunism erodes the official?s extortion power and reduces his revenues from selling permits. Even though the dynamic setting leaves the corrupt official with less extortion power, we cannot rule out the possibility that the official?s ability to apply dynamic discrimination decreases the intertemporal aggregate social welfare. We also explore the effect of the official?s tenure stability on the extent of corruption. This allows us to identify circumstances under which the often observed practice of job rotation can help mitigate corruption.

The Dynamics of Corruption with the Ratchet Effect

This paper develops a simple model to analyze the effects of mergers in complementary system markets when the merged firm is able to engage in bundling. In the short-run analysis, I analyze the impact of (mixed) bundling on pricing decisions for existing generations of products. The basic model is then extended to analyze industry dynamics where the implications of mergers for innovation incentives and technical tying/compatibility decisions are explored. Welfare implications of mergers in the shortand long-run will be also analyzed.
