Cheap talk is shown to facilitate coordination on the unique efficient equilibrium in
experimental order-statistic games. This result is roughly consistent with theoretical
predictions according to which cheap talk promotes efficient Nash play. The evidence ...

This paper experimentally investigates the evolution of message meanings when talk is
cheap. We consider communication between a privately informed sender and a receiver
when the sender's message does not affect payoffs directly. Sender-receiver games, ...

We experimentally investigate communication in sender-receiver games with imperfect
incentive alignment. We consider both a priori meaningless messages and messages with
pre-established meanings. Under four canonical incentive conditions, we get ...

This paper characterizes the set of Nash equilibria in the second-price sealed-bid auction with
independent private values and three or more bidders. In addition, we show that any effective

This paper uses curb sets to study the evolution of effective pre-play communication in
games where a single communication round precedes a simultaneous-move, complete-
information game. It is shown that the effectiveness of one-sided pre-play communication ...

This paper explores how efficiency promotes the use of structure in language. It starts from
the premise that one of language's central characteristics is to provide a means for saying
novel things about novel circumstances, its creativity. It is reasonable to expect that in a ...

This paper presents an experimental investigation of optimal learning in repeated
coordination games. We find evidence for such learning when we limit both the cognitive
demands on players and the information available to them. We also find that uniqueness ...

This paper reexamines Bertrand competition with homogeneous products and different
marginal costs. It is shown that the conventional outcome is supported by an equilibrium in
the original game under the standard rationing rule.
A Blume… - Journal of Economic Theory, 2006 - Elsevier
We study infinitely repeated first-price auctions in which a bidder only learns whether or not
he won the object. While repetition of the stage-game equilibrium is the unique Nash
equilibrium in public strategies, with patient bidders there are simple Nash equilibria in ...

Abstract We study tacit collusion in repeated auctions in which bidders can only observe
past winners and not their bids. We adopt a stringent interpretation of tacit collusion as
collusion without communication about strategies that we model as a symmetry restriction ...

We define communication-proof equilibria in simple games of communication. These
equilibria satisfy a stability condition guaranteeing that they would not be affected if new
opportunities to communicate arose. We look for partitions of possible equilibria into sets ...
B Andreas - Games and Economic Behavior, 1994 - Elsevier
Abstract The paper examines repeated games where players have the (possibly costly)
option of initiating bargaining over continuation payoffs between plays of the stage game. A
solution concept for these augmented games, renegotiation perfectness, is used to ...

Abstract This paper examines the effectiveness of perturbation refinements in sender-
receiver games. It is shown that babbling equilibria are always perfect and even proper.
However, they need not be strategically stable. An example is given where the only ...

Abstract This paper analyzes communication with a language that is vague in the sense that
identical messages do not always result in identical interpretations. It is shown that strategic
agents frequently add to this vagueness by being intentionally vague, ie they deliberately ...

Summary. We study an evolutionary model in which heterogenous boundedly rational
agents interact locally in order to play a coordination game. Agents differ in their mobility
with mobile agents being able to relocate within a country. We find that mobile agents ...

We study learning in communication games. Our main finding is that a simple forward-
looking learning rule leads to communication in a large class of games. This class is
characterized by a partial-common-interest condition. In contrast, we show that a variety of ...

Abstract This paper investigates optimal play in coordination games where cognition plays
an important role. The standard approach to games of incomplete information, which
assumes common knowledge of the structure, fails in such games. We develop a theory ...

This paper proposes a learning-efficiency explanation of modular structure in language. An

Abstract Private information about language competence drives a wedge between the
indicative meanings of messages, the sets of states indicated by those messages, and their
imperative meanings, the actions induced by those messages. When sender and receiver ...
