We say that a society has a weak norm against lying if, all other things being equal, agents rather lie in such a way that they do not get caught. We show that if this is the case then all incentive compatible social choice functions are Bayesian implementable, and furthermore, implementation...

We study Nash implementation by natural price-quantity mechanisms in pure exchange economies with free-disposal (Saijo et al., 1996, 1999) where agents have weak/strong intrinsic preferences for honesty (Dutta and Sen, 2012). Firstly, the Walrasian rule is shown to be non-implementable where all...

We study Nash implementation by natural price-quantity mechanisms in pure exchange economies when agents have intrinsic preferences for responsibility. An agent has an intrinsic preference for responsibility if she cares about truth-telling that is in line with the goal of the mechanism designer...
