A note on the tight simplification of mechanisms

Author

Listed:
  • Perez-Richet, Eduardo

Abstract

This note offers characterizations of tightness and weak tightness. It shows that when the preference domain is that of continuous utility functions on the outcome space, the two notions are equivalent to the outcome closure property of Milgrom (2010a).
