The Theory of Incentives: The Principal-Agent Model this question feed

asked by redsink on November 25, 2006 9:37 PM

Economics has much to do with incentives--not least, incentives to work hard, to produce quality products, to study, to invest, and to save. Although Adam Smith amply confirmed this more than two hundred years ago in his analysis of sharecropping contracts, only in recent decades has a theory begun to emerge to place the topic at the heart of economic thinking. In this book, Jean-Jacques Laffont and David Martimort present the most thorough yet accessible introduction to incentives theory to date. Central to this theory is a simple question as pivotal to modern-day management as it is to economics research: What makes people act in a particular way in an economic or business situation? In seeking an answer, the authors provide the methodological tools to design institutions that can ensure good incentives for economic agents.

This book focuses on the principal-agent model, the "simple" situation where a principal, or company, delegates a task to a single agent through a contract--the essence of management and contract theory. How does the owner or manager of a firm align the objectives of its various members to maximize profits? Following a brief historical overview showing how the problem of incentives has come to the fore in the past two centuries, the authors devote the bulk of their work to exploring principal-agent models and various extensions thereof in light of three types of information problems: adverse selection, moral hazard, and non-verifiability. Offering an unprecedented look at a subject vital to industrial organization, labor economics, and behavioral economics, this book is set to become the definitive resource for students, researchers, and others who might find themselves pondering what contracts, and the incentives they embody, are really all about.

I had a project work. I was struggling with a P/A model in other books' examples. But this book is a gem. I got what I wanted in less than two days. I am an average student and the various models and extensions are very helpful in understanding the material.

I love the cover and the color combination also. I dont have it now. But will buy one. G-R-E-A-T Book.

Give it a try.

The book provides a systhesis of contract theory at the phd level. It begins with basic idea of adverse selection and then its extension and followed by basic moral hazard model and its extension. The selected topics are presented here in a consistent fashion of the main ideas. Applications are well presented along the models.

Nonverifiability, the mixed model of adverse selection and moral hazard and some dynamic aspects of the two are also incorporated in a great deal of details.

This is the text on incentive theory, not just introduction. Its comprehensive insights are useful and time-saving for readers. You need not to read a bulk of papers, after reading the book, you just complement it with some core papers of the topics. (such as multidimensional screening, random participation)

If there is some weakness, it would be that... the authors present some topics too short and some notation used are not well explained, particularly the extension of the core models and some selected topics.

Anyways, i found it helpful and complete for studying incentive theory but it requires deep understanding of optimization theory and some experience of economic-theorethic arguments.

This book is written by a major contributor of the field. It would be hard to write another book to compete with this one in the field. . .
