BACKGROUNDINFORMATION

Youholdbachelor’sdegreesinphysicsandmathematics.HowdidyouendupwithaPhDin

economics?

Iwasintendingtobeahigh‐energy,particlephysicist,buttwothingsmademeabandon

thatambition.Onewasthatthesubjectwasgoingthroughwhatseemedtometobean

uninspiringpatchinthemid‐‘60s,althoughthatprobablyreflectedmyownintellectual

shortcomingsmorethanthestateofthesubject.TheotherreasonwasthattheVietnam

Warwasonand,likemanyotherstudents,Iwasbotheredbyit.Myfriendsamongthe

mathematiciansatCambridgeweren’tinterestedintheWar.Aphilosopherfriendinsisted

hedidn’thaveenoughinformationtohaveaviewabouttheWar.Ifoundthattheonly

peopleincollegewithwhomIcouldhaveinformativediscussionsontheWarandits

probablecauseswereeconomists,particularlyMarxists,whoprovidedmeone

interpretation,andpoliticalscientists,whoinsistedonanotherclassofinterpretations.

Thatwasveryeducationalforme.

InmyowncollegeatCambridge,JimMirrlees(nowSirJamesMirrlees,NobelLaureate)had

donemathasafirstdegreeandaPhDineconomics.Igottoknowhimthrougha

discussiongroupwebothbelongedto,andheencouragedmetoshifttoeconomics.And

that’swhatIdid,in1965.

Asastudent,didanyofyourprofessorsstandoutasbeingparticularlyinfluentialor

inspirational?

Thegreatestinfluencewasunquestionablymyfather,whowashoweverneverformallymy

teacher.Hewasaprofessorofeconomicsandaprofoundeducationist.Hewasalsoa

terrificfather.Ourhomewasalwaysfilledwithvisitors:hisstudents,colleagues,and

friends.Also,betweentheagesof13and15,Iwenttoaschool(nowknownasRajghat

BesantSchool,Varanasi)thatwasphenomenallygood.Icameunderthespellofseveral

remarkableteachersthere.Aboutthreemonthsago,Ivisitedthecampuswithmywife.

Idon’tbelievetherewasanybodyatuniversityinDelhiwhoinspiredme.ButasaPhD

andIcouldtellheaskeddeepquestions.

Thatwastheinfluenceofmyfather.IassumedIwouldbeanacademicbecausethat’sthe

wereoftendistinguishedacademics.Theywereinvariablykindtome,askedmequestions

privatesector,myparents’friendswouldhavemerelyinferredthatIwasn’taserious

person,mostcertainlynotagoodstudent[laughs].

Inthemidtolate1960s,atleastintheUK,studentsofmathematicswhohadconvertedto

economics(thereweren’tthatmany)wereviewedwithsuspicion.Didwehavethe“horse

immediately,sotheymusthavebeenreasonablepiecesofwork.Buttheyweretechnical

thematterwas,inthe1960sanumberofveryfineeconomiststhoughtthewayintothe

economicsofinformationwouldrequirefirstofallameasureofinformation(e.g.the

Shannonmeasure).Butthatdidn’tseemtoleadanywhere:thesocialworldrequiresa

differenttreatmentfromtheworldofcommunication.KennethArrowwasthefirstto
