I was supremely fortunate in having the opportunity to present someoftheideasinthisbooktotheEncounterswithAuthorsseries organizedbytheHarvardCenterforBasicResearchintheSocialSci- ences (CBRSS). I am particularly grateful to Jim Alt and Ken Shepsle fortheirinvitationandhospitality.Ialsobenefitedfromtheirnumer- ous insights on this project that they offered while I was there. Theparticipantsinthatworkshopwereextremelysupportive,giving me countless ideas and helping me to avoid infelicities. I am espe- cially grateful for the feedback that I received at the workshop from DaronAcemoglu,AlbertoAlesina,AbhijitBanerjee,JohnLondregan, Arthur (Skip) Lupia, Adam Meirowitz, Sharun Mukand, Jim Snyder, andEnricoSpolaore. Many people have influenced my thinking on the topics of this book. ThroughoutmycareerIhaveenjoyedthecounseland,above all, friendship of Steve Coate. He and I have collaborated on a large number of projects and many ideas developed here (especially the goodones!)areprobablyhis.However,theyhavebeenetchedintomy mindbyyearsofdiscussionwithStevesothatInolongerrecognize this. Anne Case collaborated with me in my first efforts in political economy when we stumbled on the agency approach while trying tounderstanddeterminantsofre-electionratesamongUSgovernors. Annehastaughtmemanythingswhicharerelevanttotheideasin thisbookandthepartofChapter3onUSgovernorsisbasedonour joint work. Michael Smart has also collaborated with me in under- standing the agency model in public finance settings.
