ABSTRACT
The modern era of social choice theory began with Kenneth Arrow’s pathbreaking monograph [4] and his celebrated impos sibility theorem. The purpose of the present monograph is to recount contributions to social choice that are based on Arrow’s approach and succeeding developments. Its emphasis will be on the interactions among various conditions that relate social choices to individuals’ values or preferences, and on the possibility/ impossibility results that flow from these interactions. Special attention will be devoted to interprofile and intraprofile conditions [54] and their roles in generating impossibility theorems.
