It is indeed a fine contribution to the economics literature."--Sir James Mirrlees! Cambridge University! 1996 Nobel Laureate in Economic Sciences"The most important development in economics in the last forty years has been the study of incentives to achieve potential mutual gains when the parties have different degrees of knowledge. The time is ripe for a synthesis and systematization. Jean-Jacques Laffont has been one of the most important contributors to the field over the years! and David Martimort has shown his capacity for highly original work. This book! dealing with the basic models of the field! combines clarity! thoroughness! and great respect for historical development."--Kenneth J. Arrow!
