<P>Few economists have been as prolific and wide-ranging as Takashi Negishi. Part of the "Hicksian" generation of Neo-Walrasian general equilibrium theorists, Negishi rose to prominence&nbsp;during the early 1960s with his work on the Neo-Walrasian system. Negishi's signature has been his attempt to extend the multi-market Neo-Walrasian system in several directions to incorporate concerns such as imperfect comptetition, stability, money, trade and unemployment - and, as a consequence, helping to discover and delineate the limits of conventional theory. </P>
<P>This collection in honour of Takashi Negishi analyses his contributions to the history of economic theory. Economists paying tribute within this volume include Neri Salvadori, Laurence Moss, and Joaquim Silvestre. </P>
