Repeated Nash Implementation

Abstract:     
This paper studies repeated implementation of social choice functions in environments with complete information and changing preferences. We introduce the condition of dynamic monotonicity and show that it is necessary for repeated implementation in finite as well as infinite horizon problems. With at least three agents, the conditions of dynamic monotonicity and no-veto power are sufficient. In infinite horizon problems with high enough discount factors, dynamic monotonicity implies weak efficiency in the range (Lee and Sabourian, 2011), while Maskin monotonicity implies dynamic monotonicity in finite horizon problems.
