Professor Lancaster has made a major contribution to consumer theory. His work on the consumer's decision-making process has been particularly influential. This coherent thematic selection of his most important recent essays, some of which are published here for the first time, reflect the major features of Professor Lancaster's work. The essays form a unified collection on consumer choice and product variety and will be essential reading for any economist with an interest in the most recent developments in modern microeconomics.

Graduate-level text provides complete and rigorous expositions of economic models analyzed primarily from the point of view of their mathematical properties, followed by relevant mathematical reviews. Part I covers optimizing theory; Parts II and III survey static and dynamic economic models; and Part IV contains the mathematical reviews, which range fromn linear algebra to point-to-set mappings.

Almost two hundred and forty years ago, an English clergyman named Thomas Bayes developed a method to calculate the chances of uncertain events. While his method has extensive applications to the work of applied economists, it is only recent advances in computing that have made it possible to exploit the full power of the Bayesian way of doing applied economics.In this new and expanding area, Tony Lancasters text provides a comprehensive introduction to the Bayesian way of doing applied economics. Using clear explanations and practical illustrations and problems, the text presents innovative, computer-intensive ways for applied economists to use the Bayesian method.The Introduction emphasizes computation and the study of probability distributions by computer sampling, showing how these techniques can provide exact inferences about a wide range of econometric problems. Covering all the standard econometric models, including linear and non-linear regression using cross-sectional, time series, and panel data, it also details causal inference and inference about structural econometric models. In addition, each chapter includes numerical and graphical examples and demonstrates their solutions using the S programming language and Bugs software.

This work follows on from the two previous volumes in presenting the intellectual development of some of this century's most influential economists. The careers, education, achievements and views on future research are presented by economists who have made important contributions to the subject.
