When and Why? A Critical Survey on Coordination Failure in the Laboratory (2006)
Devetag, Giovanna, Ortmann, Andreas
Coordination games with Pareto-ranked equilibria have attracted major theoretical attention over the past two decades. Two early path-breaking sets of experimental studies were widely interpreted as...
Representing others' preferences in mixed motive games: was Schelling right? (2002)
Devetag, Giovanna, Warglien, Massimo
The available experimental evidence suggests that even two-person normal form games with an elementary action space present substantial degrees of cognitive difficulty. We submit that the relational...
Precedent transfer in coordination games: experimental evidence (2002)
In this work we study the power of precedent transfer in improving coordination in the minimum effort game with large groups. We test whether groups which play a different coordination game in which...
Games and Phone Numbers: Do Short Term Memory Bounds Affect Strategic Behavior? (2002)
Devetag, Giovanna, Warglien, Massimo
Research in experimental and behavioral game theory has revealed a substantial and persistent degree of heterogeneity in the strategic behavior of real individuals. While the prevailing theoretical...
Coordination and information in critical mass games: an experimental study (2002)
We present experimental results on a repeated coordination game with Pareto-ranked equilibria in which a payoff from choosing an action is positive only if a critical mass of players choose that...
Coordination and self-organization in minority games: experimental evidence (2002)
Bottazzi, Giulio, Devetag, Giovanna
This work presents experimental results on a coordination game in which agents must repeatidly choose between two sides, and a positive fixed payoff is assigned only to agents who pick the...
The imperfect hiding : some introductory concepts and preliminary issues on modularity (2001)
Devetag, Giovanna, Zaninotto, Enrico
In this work we present a critical assessment of some problems and open questions on the debated notion of modularity. Modularity is greatly in fashion nowadays, being often proposed as the new...
Adaptive learning and emergent coordination in minoriry games (2001)
Bottazzi, Giulio, Devetag, Giovanna, Dosi, Giovanni
The work studies the properties of a coordination game in which agents repeatedly compete to be in the population minority. The game re ects some essential features of those economic situations in...
Bottazzi, Giulio, Devetag, Giovanna
In this paper we present results of simulations in which we use a general probabilistic learning model to describe the behavior of heterogeneous agents in a non-cooperative game where it is rewarding...

Transfer, Focality and Coordination: Some Experimental Results
In this paper we test the degree of tranfer of learning between two similar, n-player coordination games with Pareto-ranked equilibria with fixed cohorts. Our results show that achieve the...

Are communication failures common? We revisit a classic example of experimental coordination failure and explore, in a 2x2 design, the effects of deviation costs and loss avoidance. Our results...

Does Variance matter? Expectations of price return and variability in an asset pricing experiment.
Giulio Bottazzi, Giovanna Devetag, Francesca Pancotto
In this work we describe a laboratory experiment on the emergence and coordination of expectations in a pure exchange framework. We consider a simple two asset economy with a riskless bond and a...

It has been suggested that players often produce simplified and/or misspecified mental representations of interactive decision problems (Kreps, 1990). We submit that the relational structure of...
