摘要:
An important issue for economics and the decision sciences is to understand why allocation and decision procedures are plagued by manipulative and paradoxical behavior once there are n greater than or equal to 3 alternatives. Valuable insight is obtained by exploiting the relative simplicity of the widely used Copeland method (CM). By using a geometric approach, we characterize all CM manipulation, monotonicity, consistency, and involvement properties while identifying all profiles which are susceptible to these difficulties. For instance, we show for n = 3 candidates that the CM minimizes the negative aspects of the Gibbard-Satterthwaite theorem. (C) 1997 Academic Press.
