If you are interested in what makes great E economists tick, this book makes for fascinating reading.” S Roger Backhouse, Department of Economics, University of Birmingham, United O Kingdom F “This is the fourth edition of one of my favorite books. It consists of lectures by Nobel T laureates, each of whom was asked to describe the development of their H principal contribution to economics and to do so in language accessible to a lay E audience. One of these laureates, George Stigler, is famous for denying the L relevance of biography to intellectual history. Every page of this book refutes his A thesis.

TheNobelPrizeinEconomicswasnotcreatedbyAlfredNobelhimself.

In the case of the natural sciences, the awardsweretobegivenfor“discoveries,”“inventions,”and“improve- ments.”In1968theCentralBankofSweden,inconnectionwithitster- centenarycelebration,initiatedanewaward,theCentralBankofSweden Prize in Economic Science in Memory of Alfred Nobel. This prize was tobegrantedinconformitywiththestandardsthatgovernedtheaward- ingoftheoriginalNobelprizes.Accordingtotherulesestablishedbythe CentralBankofSweden,the“Prizeshallbeawardedannuallytoaperson who has carried out a work in economic science of the eminent signifi- cance expressed in the will of Alfred Nobel.”1 The idea for a series of autobiographical lectures by Nobel laureates in economics was that of the senior editor, who has spent a good part of his academic career studying, teaching, and writing about the lives and ideas of leading contemporary American economists.2 This abiding interest in the relationship between biography and the creative process led naturally to the thought of providing a forum in which outstanding economists would express in their own words, in any way that seemed viii IntroductiontotheFourthEdition congenial,apersonalmemoirunderthegeneralrubric“MyEvolutionas an Economist.” At the very least such a forum would preserve part of therichrecordofaccomplishmentthathelpedtoshapethedirectionand character of economic science in the post–World War II era.

But whom to invite? It was clear that budgetary and time constraints would limit the number of invitations, and so the roster was restricted in the following ways: (1) only economists who served on the faculties ofAmericanuniversitiesatthetimetheNobelPrizewasawardedwould be included; and (2) the roster would represent as many different facets of economics in terms of types of contributions, specific areas, methods ofanalysis,andideologicaldifferences aspossible.Thismeantthatonly one member of a team of co-recipients of the prize would be invited. In 1983, when the program was being planned, there were twelve winners of the Nobel Prize who met the first criterion, although one was too ill to travel. A difficult winnowing process in accordance with the second criterion narrowed the final list to eight. To our pleasant surprise, only one invitee declined to participate.

Economists at American universities continued to receive the Nobel Prize. The third edition, published in 1995, included Trinity University lectures by William F.

As one of the invitees put it, “I do not know thatIcouldkeepitbetweentheScyllaoffalsemodestyandtheCharybdis of boastfulness, and I am afraid I would find the whole business rather stressful.” Moreover, most of their work in its professional formulation was technical in nature, closed off to those not trained as economists. Yet each was being asked to make his contribution accessible to a lay audienceatapubliclectureopentothewholecommunity.Thisprovided greater difficulties for some than for others. Samuelson’s and Arrow’s scientific contributions are largely in the domain of mathematical eco- nomics.KleinandHeckman,amongothers,makeheavyuseofstatistical techniques and econometrics. All the Nobel economists express them- selves in the technical vocabulary of their discipline. And yet in each instance, as the reader of these pages will discover, each speaker somehow managed to convey the nature and significance of his contributions. (The essays in this book are in the order in which they were presented in the Trinity lecture series.) It is hard to imagine a
