This paper discusses the implications of strategic voting for institutional design in environments where the only role of elections is to aggregate information. We adopt a mechanism design perspective, which assumes that prior to a standard voting game, a fictitious designer has to select the...

Misrepresenting private information is often costly. This paper studies a model of strategic information transmission based on Crawford and Sobel (1982)(CS), but with a signaling dimension where there is a convex cost of misreporting. I identify a simple condition, called No Incentive to...

We revisit Sen's (1970) Paradox in its formulation for collective choice rules. It is well-known that under unrestricted domain, binary liberalism (BL) and the global (resp. binary) Weak Pareto principle (GWP/BWP) are incompatible with binary rejection consistency (resp. binariness). We first...

Austen-Smith and Banks (Journal of Economic Theory, 2000) study how money burning can expand the set of pure cheap talk equilibria of Crawford and Sobel (Econometrica, 1982). This note identifies an error in the main Theorem of Austen-Smith and Banks, and provides a variant that preserves some...

We study full-implementation in Nash equilibrium under complete information. We generalize the canonical model (Maskin, 1977) by allowing agents to send evidence or discriminatory signals. A leading case is where evidence is hard information that proves something about the state of the world. In...

This paper reconsiders the evidence on lying or deception presented in Gneezy (2005,American Economic Review). We argue that Gneezy?s data cannot reject the hip?esis that people are one of two kinds: either a person will never lie, or a person will lie whenever she prefers the outcome obtained...
