Contract Theory

A comprehensive introduction to contract theory, emphasizing common themes and methodologies as well as applications in key areas. Despite the vast research literature on topics relating to contract theory, only a few of the field's core ideas are covered in microeconomics textbooks. This long-awaited book fills the need for a comprehensive textbook on contract theory suitable for use at the graduate and advanced undergraduate levels. It covers the areas of agency theory, information economics, and organization theory, highlighting common themes and methodologies and presenting the main ideas in an accessible way. It also presents many applications in all areas of economics, especially labor economics, industrial organization, and corporate finance. The book emphasizes applications rather than general theorems while providing self-contained, intuitive treatment of the simple models analyzed. In this way, it can also serve as a reference for researchers interested in building contract-theoretic models in applied contexts.The book covers all the major topics in contract theory taught in most graduate courses. It begins by discussing such basic ideas in incentive and information theory as screening, signaling, and moral hazard. Subsequent sections treat multilateral contracting with private information or hidden actions, covering auction theory, bilateral trade under private information, and the theory of the internal organization of firms; long-term contracts with private information or hidden actions; and incomplete contracts, the theory of ownership and control, and contracting with externalities. Each chapter ends with a guide to the relevant literature. Exercises appear in a separate chapter at the end of the book.

This book is both an examination of, and a contribution to, our understanding of the theoretical foundations of the common law of contract. Focusing on contemporary debates in contract theory, Contract Theory aims to help readers better understand the nature and justification of the general idea of contractual obligation, as well as the nature and justification of the particular rules that make up the law of contract. The book is in three parts. Part I introduces the idea of 'contract theory', and presents a framework for identifying, classifying, and evaluating contract theories. Part II describes and evaluates the most important general theories of contract; examples include promissory theories, reliance-based theories, and economic theories. In Part III, the theoretical issues raised by the various specific doctrines that make up the law of contract (e.g., offer and acceptance, consideration, mistake, remedies, etc.) are examined in separate chapters. The legal focus of the book is the common law of the United Kingdom, but the theoretical literature discussed is international in origin; the arguments discussed are thus relevant to understanding the law of other common law jurisdictions and, in many instances, to understanding the law of civil law jurisdictions as well.

In recent years there has been a significant increase of interest in continuous-time Principal-Agent models, or contract theory, and their applications. Continuous-time models provide a powerful and elegant framework for solving stochastic optimization problems of finding the optimal contracts between two parties, under various assumptions on the information they have access to, and the effect they have on the underlying "profit/loss" values. This monograph surveys recent results of the theory in a systematic way, using the approach of the so-called Stochastic Maximum Principle, in models driven by Brownian Motion. Optimal contracts are characterized via a system of Forward-Backward Stochastic Differential Equations. In a number of interesting special cases these can be solved explicitly, enabling derivation of many qualitative economic conclusions.

Very diverse societies pose real problems for Rawlsian models of public reason. This is for two reasons: first, public reason is unable accommodate diverse perspectives in determining a regulative ideal. Second, regulative ideals are unable to respond to social change. While models based on public reason focus on the justification of principles, this book suggests that we need to orient our normative theories more toward discovery and experimentation. The book develops a unique approach to social contract theory that focuses on diverse perspectives. It offers a new moral stance that author Ryan Muldoon calls, "The View From Everywhere," which allows for substantive, fundamental moral disagreement. This stance is used to develop a bargaining model in which agents can cooperate despite seeing different perspectives. Rather than arguing for an ideal contract or particular principles of justice, Muldoon outlines a procedure for iterated revisions to the rules of a social contract. It expands Mill's conception of experiments in living to help form a foundational principle for social contract theory. By embracing this kind of experimentation, we move away from a conception of justice as an end state, and toward a conception of justice as a trajectory.

These articles should be helpful to anyone with training in economics.

Legal thinkers typically justify contract law on the basis of economics or promissory morality. But Peter Benson takes another approach. He argues that contract is best explained as a transfer of rights governed by a conception of justice. The result is a comprehensive theory of contract law congruent with Rawlsian liberalism.

This book presents theoretical research between wireless communications, networking, and economics using the framework of contract theory. This work fills a void in the literature by closely combining contract theoretical approaches with wireless networks design problems. Topics covered include classification in contract theory, reward design, adverse selection, and moral hazard. The authors also explore incentive mechanisms for device-to-device communication in cellular networks, insurance plans for service assurance in cloud computing markets with incomplete information, multi-dimensional incentive mechanisms and tournament based incentive mechanisms in mobile crowdsourcing. Financial applications include financing contracts with adverse selection for spectrum trading in cognitive radio networks and complementary investment of infrastructure and service providers in wireless network visualization. This book offers a useful reference for engineers and researchers in the wireless communication community who seek to integrate the notions from contract theory and wireless engineering, while emphasizing on how contract theory can be applied in wireless networks. It is also suitable for advanced-level students studying information systems or communications engineering.

Modern Social Contract Theory provides an exposition and evaluation of major work in social contract theory from 1950 to the present. It locates the central themes of that theory in the intellectual legacy of utilitarianism, particularly the problems of defining principles of justice and of showing the grounds of moral obligation. It demonstrates how theorists responded in a novel way to the dilemmas articulated in utilitarianism, developing in their different approaches a constructivist method in ethics, a method that aimed to vindicate a liberal, democratic and just political order. A distinctive feature of the book is its comparative approach. By placing the works of Barry, Buchanan and Tullock, Harsanyi, Gauthier, Grice, Rawls, and Scanlon alongside one another, similarities and differences are brought out, most notably in the way in which principles are derived by each author from the contractual construction as well as the extent to which the obligation to adopt those principles can be rationally grounded. Each theory is placed in its particular intellectual context. Special attention is paid to the contrasting theories of rationality adopted by the different authors, whether that be utility theory or a deliberative conception of rationality, with the intention of assessing how far the principles advanced can be justified by reference to the hypothetical choices of rational contracting agents. The book concludes with a discussion of some principal objections to the enterprise of contract theory, and offers its own programme for the future of that theory taking the form of the empirical method.
