I study a model of strategic communication between an uninformed Receiver and an
informed but upwardly biased Sender. The Sender bears a cost of lying, or more broadly, of
misrepresenting his private information. The main results show that inflated language ...
This paper studies a model of strategic communication by an informed and upwardly biased
sender to one or more receivers. Applications include situations in which (i) it is costly for the
sender to misrepresent information, due to legal, technological, or moral constraints, or (ii) ...

We study a one-dimensional Hotelling-Downs model of electoral competition with the
following innovation: a fraction of candidates have" character" and are exogenously
committed to a campaign platform; this is unobservable to voters. Character is desirable, ...

There are typically multiple equilibrium outcomes in the Crawford–Sobel (CS) model of
strategic information transmission. This paper identifies a simple condition on equilibrium
payoffs, called NITS (no incentive to separate), that selects among CS equilibria. Under a ...

Abstract This paper reinterprets the evidence on lying or deception presented in Gneezy
(Am. Econ. Rev. 95 (1): 384–394, 2005). We show that Gneezy's data are consistent with the
simple hypothesis that people are one of two kinds: either a person will never lie, or a ...

Abstract: 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 ...

Abstract We study a model where a decision maker (DM) must rely on an adviser for
information about the state of the world relevant for her decision. The adviser has the same
underlying preferences as the DM; he may differ, however, in his prior belief about the ...

Abstract Elections with sequential voting, such as presidential primaries, are widely thought
to feature social learning and momentum effects, where the choices of early voters influence
the behavior of later voters. Momentum may take time to build, and can depend on how ...

We study a model where a decision maker (DM) must select an adviser to advise her about
an unknown state of the world. There is a pool of available advisers who all have the same
underlying preferences as the DM; they differ, however, in their prior beliefs about the ...

Abstract: 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

In the last decade, Marie Jean Antoine Nicolas de Caritat Marquis de Condorcet's (1785)
theory of committee decision making has emerged as a workhorse model in political
economy, par? ticularly voting theory. In its simplest modern formulation, the" Condorcet ...

Abstract This paper studies a simple model of observational learning where agents care not
only about the information of others but also about their actions. We show that despite the
complex strategic considerations that arise from forward-looking incentives, herd behavior ...

Abstract This paper analyzes the choice of optimal voting rules under various theories of
voting behavior: strategic voting, informative or sincere voting, level-k or cognitive hierarchy
voting, and mixtures among all of these. We show that if preferences are homogeneous, ...

Abstract. 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 ...

Abstract: 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 ...
Abstract 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 paper proves their conjecture on continuity of the equilibrium ...

Abstract. We generalize the canonical problem of Nash implementation by allowing agents
to voluntarily provide discriminatory signals, ie evidence. Evidence can either take the form
of hard information or, more generally, have differential but non-prohibitive costs in ...

Abstract This paper develops an informational but rational theory of cascade behavior when
voting is sequential. We analyze a two-candidate election in which voters are uncertain
about the realization of a state variable that affects the utility of all voters. Voters vote in an ...

Abstract This note shows that the conventional outcome associated with Bertrand
competition with homogenous products and different marginal costs is obtained in every
Nash equilibrium in which firms use undominated strategies. This strengthens an ...

Abstract This note considers (complete information) Nash-implementation when mixed
strategies are properly accounted for and the outcome space is infinite. We first construct an
example in which preferences over lotteries fail the Archemedian axiom and show that, ...

Abstract We develop a simple model to study the impact of special interest politics (SIP) on
the quality of politicians. The basic setting is a citizen-candidate model in which, following
the election, the chosen official interacts with lobby groups. Citizens differ along two ...

Abstract We study a Downsian model where office-motivated candidates have policy-

efficient information aggregation because policy positions reveal private information. A ...

In this Supplementary Appendix, we formally study an infinitely repeated version of the
baseline model, in which insiders are infinite-lived and discount the future at the rate δ∈(0,

This supplementary appendix adds detail and formal results to the discussion in Section 5 of
Kartik and McAfee (forthcoming). For consistency with the main article, Theorems here are
numbered starting from 3 and equations starting from 4. References to Theorem 1 are to ...

The Sen Paradox, also known as the Impossibility of a Paretian Liberal, is a famous result in
the field of social choice theory. Loosely speaking, it alleges a conflict between the
principles of efficiency and liberalism. Since its original formulation over thirty years ago ...
Abstract We study observational learning in environments with congestion costs: as more of
one's predecessors choose an action, the payoff from choosing that action decreases. If
congestion on either action can get so large that an agent would prefer to take the other ...

Abstract We study the characteristics of self-selected candidates in corrupt political systems.
Potential candidates differ along two dimensions of unobservable character: public spirit

Sender strategies and then applies iterative deletion of weakly dominated strategies. This
procedure selects among Crawford and Sobel (1982) equilibria, typically selecting the ...
Abstract: 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 ...
