Proiectarea mecanismului

Diagrama Stanley Reiter
Diagrama Stanley Reiter de mai sus ilustrează un joc al proiectării mecanismului. Partea de sus stânga Θ arată spaţiul tip iar partea de sus dreapta spaţiul X al rezultatelor. Funcţia de selecţie socială f(θ) mapează un profil tip pentru un rezultat. În jocurile de proiectare a mecanismului, agenţii trimit mesaje M într-un mediu de joc g. Echilibrul în joc ξ(M,g,θ) poate fi proiectat pentru a implementa funcţia de selecţie socială f(θ).

Proiectarea mecanismului (numit uneori şi teoria jocului inversat[1]) este un domeniu al teoriei jocului care studiază conceptele de soluţie pentru o clasă de jocuri de informaţii private. Caracteristicile distinctive ale acetor jocuri sunt:

  • un "proiectant" al jocului alege o nouă structură a jocului mai degrabă decât o moşteneşte
  • proiectantul este interesat în rezultatul jocului

Un astfel de joc este denumit "proiectarea mecanismului jocului" şi este de obicei soluţionat prin motivarea agenţilor pentru a divulga informaţiile lor private. Premiul Nobel pentru Economie în 2007 a fost acordat lui Leonid Hurwicz, Eric Maskin, şi Roger Myerson pentru "contribuţii la fondarea teoriei proiectării mecansimului".[2]
