Cooperative strategies in anonymous economies: An experiment

Camera, Gabriele; Casari, Marco; Bigoni, Maria - In: Games and Economic Behavior 75 (2012) 2, pp. 570-586

We study cooperation in economies of indefinite duration. Participants faced a sequence of prisonerʼs dilemmas with anonymous opponents. We identify and characterize the strategies employed at the individual level. We report that (i) grim trigger does not describe well individual play and there...

Indeterminacy of reputation effects in repeated games with contracts

Wolitzky, Alexander - In: Games and Economic Behavior 73 (2011) 2, pp. 595-607

repeated games with long-run players. We proceed by extending the analysis of Abreu and Pearce (2007) by allowing for the …, whether reputation effects emerge in repeated games with contracts depends on details of the prior distribution over …

Equilibrium selection in static and dynamic entry games

Duffy, John; Ochs, Jack - In: Games and Economic Behavior 76 (2012) 1, pp. 97-116

We experimentally assess the predictive power of two equilibrium selection principles for binary N-player entry games … with strategic complementarities. In static entry games, we test the theory of global games which posits that players play … games of complete information as if they were playing a related global game of incomplete information. By contrast, in …

Information-sharing in social networks

Kleinberg, Jon; Ligett, Katrina - In: Games and Economic Behavior 82 (2013) C, pp. 702-716

We present a new model for reasoning about the way information is shared among friends in a social network and the resulting ways in which the social network fragments. Our model formalizes the intuition that revealing personal information in social settings involves a trade-off between the...

Monitored by your friends, not your foes: Strategic ignorance and the delegation of real authority

Dominguez-Martinez, Silvia; Sloof, Randolph; Siemens, … - In: Games and Economic Behavior 85 (2014) C, pp. 289-305

In this laboratory experiment we study the use of strategic ignorance to delegate real authority within a firm. A worker can gather information on investment projects, while a manager makes the implementation decision. The manager can monitor the worker. This allows her to exploit any...

Strategy-proof contract auctions and the role of ties

Weerdt, Mathijs M. de; Harrenstein, Paul; Conitzer, Vincent - In: Games and Economic Behavior 86 (2014) C, pp. 405-420

A contract auction establishes a contract between a center and one of the bidders. As contracts may describe many terms, preferences over contracts typically display indifferences. The Qualitative Vickrey Auction (QVA) selects the best contract for the winner that is at least as good for the...

Epistemic equivalence of extended belief hierarchies

Tsakas, Elias - In: Games and Economic Behavior 86 (2014) C, pp. 126-144

In this paper, we introduce a notion of epistemic equivalence between hierarchies of conditional beliefs and hierarchies of lexicographic beliefs, thus extending the standard equivalence results of Halpern (2010) and Brandenburger et al. (2007) to an interactive setting, and we show that there...

Judgment aggregation in search for the truth

Bozbay, İrem; Dietrich, Franz; Peters, Hans - In: Games and Economic Behavior 87 (2014) C, pp. 571-590

We analyze the problem of aggregating judgments over multiple issues from the perspective of whether aggregate judgments manage to efficiently use all voters' private information. While new in judgment aggregation theory, this perspective is familiar in a different body of literature about...

Existence, incentive compatibility and efficiency of the rational expectations equilibrium

Sun, Yeneng; Wu, Lei; Yannelis, Nicholas C. - In: Games and Economic Behavior 76 (2012) 1, pp. 329-339

The rational expectations equilibrium (REE), as introduced in Radner (1979) in a general equilibrium setting à la Arrow–Debreu–McKenzie, often fails to have desirable properties such as universal existence, incentive compatibility and efficiency. We resolve those problems by providing a new...
