Let the Dummy Talk!- Unilateral Communication and Discrimination inThree-Person Dictator Experiments -

Greiner, Ben; Güth, Werner; Zultan, Ro’i - Max-Planck-Institut für Ökonomik <Jena> - Abteilung … - 2005

To explain why pre-play communication increases cooperation in games,one refers to a) strategic causes such as efficient communication or reputationeffects, and b) changes in the utilities due to social processes. Hithertoexperimental support for both explanations is mixed and confounded....

The dynamic interplay of inequality and trust: an experimental study

Greiner, Ben; Ockenfels, Axel; Werner, Peter - 2007

We study the interplay of inequality and trust in a dynamic game, in which trust increases efficiency and thus allows … higher growth of the experimental economy in the future. We find that trust is initially high in a treatment starting with … equal endowments, but decreases over time. In a treatment with unequal endowments, trust is initially lower yet remains …

New Experimental Results on the Solidarity Game

Büchner, Susanne; Coricelli, Giorgio; Greiner, Ben - Max-Planck-Institut für Ökonomik <Jena> / Abteilung … - 2003

This paper revisits and extends the experiment on the solidarity gameby Selten and Ockenfels (1998). We replicate the basic design of the solidaritygame and extend it in order to test the robustness of the fixed totalsacrifice' effect and the applied strategy method. Our results only...

New Experimental Results on the Solidarity Game

Büchner, Susanne; Coricelli, Giorgio; Greiner, Ben - 2004

This paper revisits and extends the experiment on the solidarity game by Selten and Ockenfels (1998). We replicate the basic design of the solidarity game and extend it in order to test the robustness of the "fixed total sacrifice" effect and the applied strategy method. Our results only...

Democratic punishment in public good games with perfect and imperfect observability

Ambrus, Attila; Greiner, Ben - 2015

In the context of repeated public good contribution games, we experimentally investigate the impact of democratic punishment, when members of a group decide by majority voting whether to inflict punishment on another member, relative to individual peer-to-peer punishment. Democratic punishment...

Homotopy Methods to Compute Equilibria in Game Theory

Herings, P. Jean-Jacques - 2011

This paper presents a complete survey of the use of homotopy methods in game theory. Homotopies allow for a robust computation of game-theoretic equilibria and their refinements. Homotopies are also suitable to compute equilibria that are selected by various selection theories. We present all...

A Folk Theorem for Bargaining Games

Herings, P. Jean-Jacques - 2012

We study strategies with one–period recall in the context of a general class of multilateral bargaining games. A strategy has one–period recall if actions in a particular period are only conditioned on information in the previous and the current period. We show that if players are...

An Interior-Point Path-Following Method to Compute Stationary Equilibria in Stochastic Games

Herings, P. Jean-Jacques - 2020

Subgame perfect equilibrium in stationary strategies (SSPE) is the most important solution concept used in applications of stochastic games, which makes it imperative to develop efficient numerical methods to compute an SSPE. For this purpose, this paper develops an interior-point path-following...
