General Equilibrium Theory

Ross M. Starr is Professor of Economics at the University of California, San Diego, where he has taught since 1980. He has also served on the faculties of Yale University, Connecticut, the London School of Economics and Political Science and the University of California, Davis, and he held a Guggenheim Fellowship at the University of California, Berkeley. Professor Starr's research focuses on general equilibrium theory, mathematical economics and monetary theory. He is the editor of General Equilibrium Models of Monetary Economies (1989) and coeditor of the three-volume Essays in Honor of Kenneth Arrow (Cambridge, 1986). His articles have appeared in journals such as Econometrica, Economic Theory, the Journal of Economic Theory, the Journal of Money, Credit, and Banking, the Quarterly Journal of Economics and the Review of Economic Studies. Cambridge University Press released the first edition of General Equilibrium Theory: An Introduction in 1997.

'Most books on the theory of general equilibrium have adopted the terribly arid axiomatic style illustrated in pure mathematics by Nicolas Bourbaki's treatise. That style makes no compromise with rigor. But it often defies intuition. Ross Starr's book is the best attempt so far at combining economic intuition with rigor in dealing with those staples of general equilibrium theory that are the existence and the two welfare theorems. Part A … deals with special cases of the general equilibrium model up to the two-good, two-factor, two-agent model, something that is never done in more 'advanced' presentations. Part B is a remarkably lucid introduction to the mathematics of point-set topology needed in any serious study of the general equilibrium model. Both parts will be welcomed by undergraduate students.' Yves Balasko, University of York
