Bøger af Ken Binmore

This short book asks how such questions arose from the social and political realities of the times in which the early utilitarians lived. This book argues that the answers to all the questions that the early utilitarians found so difficult are transparent when we stand upon their shoulders to look back upon their work.

It is widely held that Bayesian decision theory is the final word on how a rational person should make decisions. However, Leonard Savage--the inventor of Bayesian decision theory--argued that it would be ridiculous to use his theory outside the kind of small world in which it is always possible to "e;look before you leap."e; If taken seriously, this view makes Bayesian decision theory inappropriate for the large worlds of scientific discovery and macroeconomic enterprise. When is it correct to use Bayesian decision theory--and when does it need to be modified? Using a minimum of mathematics, Rational Decisions clearly explains the foundations of Bayesian decision theory and shows why Savage restricted the theory's application to small worlds. The book is a wide-ranging exploration of standard theories of choice and belief under risk and uncertainty. Ken Binmore discusses the various philosophical attitudes related to the nature of probability and offers resolutions to paradoxes believed to hinder further progress. In arguing that the Bayesian approach to knowledge is inadequate in a large world, Binmore proposes an extension to Bayesian decision theory--allowing the idea of a mixed strategy in game theory to be expanded to a larger set of what Binmore refers to as "e;muddled"e; strategies. Written by one of the world's leading game theorists, Rational Decisions is the touchstone for anyone needing a concise, accessible, and expert view on Bayesian decision making.

Economists have in recent years found the theory of games to be an attractive route for exploring imperfectly competitive markets. In this collection of articles, some of the best minds in contemporary economics on both sides of the Atlantic xplore both the potential and the limitations of this theoretical framework.
