DESCRIPTION:Posterior implementation is a solution concept for mechanism d
 esign with interdependent values. It requires that each agent’s strategy
  is optimal against the strategies of other agents for every possible mess
 age profile. Green and Laffont (1987) give a geometric characterization of
  posterior implementable social choice functions for binary collective dec
 ision problems with two agents and non-transferable utility. This paper ge
 neralizes the analysis to any finite number n of agents\, with three main 
 insights. First\, posterior implementable social choice functions are post
 erior implementable by score voting: each agent submits a number from a se
 t of consecutive integers\; the collective decision is determined by wheth
 er or not the sum exceeds a given quota. Second\, the possibility for post
 erior implementation depends crucially on the number of agents: in generic
  environments with n ≥ 3 agents\, a (responsive) social choice function 
 is posterior implementable [...]
