U jednoj godini tri Nobelove zvezde iz ekonomije - I deo
In one year three Nobel stars in economics: Part one
Sažetak
Nobelovu nagradu iz ekonomije za 1994. godinu 'za pionirsku analizu ravnoteže u teoriji nekooperativnih igara' dobili su Džon Čarls Haršanji, Rajnhard Zelten i Džon F. Neš. Haršanjijev najznačajniji doprinos je u sagledavanju problematike informacija. Odnosno, stepen informisanosti igrača od ključnog je značaja za tok i rezultat igre, ali i za primenu teorije igara u analizama konkretnih problema. Na igre sa nepotpunim informacijama nije bilo moguće primeniti standardnu proceduru rešavanja. Haršanji je ponudio originalno rešenje predloživši prevođenje igara sa nepotpunim informacijama u igre sa nesavršenim informacijama. Analiza ovog nobelovca imala je veliki uticaj na razvoj i usavršavanje ekonomike informacija, a razvijanjem koncepta rešavanja igara sa nepotpunim informacijama podstaknuta je široka primena teorije igara na mnoge probleme ekonomske nauke.
Abstract
1994 Nobel Prize in Economics 'for their pioneering analysis of equilibrium in the theory of non-cooperative games' was awarded to John Charles Harsanyi, Reinhard Selten and John F. Nash. Harsanyi’s most important contribution was in the field of economics of information. He showed how the amount of information possessed by agents bears the key significance to the course and result of the game, but also to the implementation of game theory in the analysis of concrete problems. It was impossible to apply the standard solving procedure to the incomplete information games. Harsanyi offered an original solution by proposing the conversion of a game with incomplete information into one with complete yet imperfect information. The analysis of this Nobel Prize winner largely contributed to the development and advancement of the economics of information, whereas his concept of solving games with incomplete information triggered the widespread application of game theory to many other problems in the economic science.
