Positive and Negative Team Identity in a Promotion Game

Eberlein, Marion; Walkowitz, Gari - 2008

In this paper we experimentally investigate whether the so-called in-group/out-group bias leads to a favoring of own team members as candidates in promotion (by voting for them) relative to other teams and their members. In contrast to psychological approaches, mon- etary incentives for voting...

War and relatedness

Spolaore, Enrico; Wacziarg, Romain - 2009

We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...

Social welfare versus inequality concerns in an incomplete contract experiment

Faravelli, Marco; Kirchkamp, Oliver; Rainer, Helmut - 2010

We study a situation where two players first choose a sharing rule, then invest into a joint production process, and then split joint benefits. We investigate how social preferences determine investments. In our experiment we find that even the materially disadvantaged player cares more for...

Reputation, social identity and social conflict

Smith, John - 2007

We interpret the psychology literature on social identity and examine its implications in a population partially composed of such agents. We model a population of agents from two exogenous and well defined social groups. Agents are randomly matched to play a reduced form bargaining game. We show...

Growth of strategy sets, entropy and nonstationary bounded recall

Neyman, Abraham; Okada, Daijiro - 2005

This paper initiates the study of long term interactions where players' bounded rationality varies over time. Time dependent bounded rationality is reflected in part in the number $\psi(t)$ of distinct strategies in the first $t$-stages. We examine how the growth rate of $\psi_i(t)$ affects...

Occupational choice and social contacts across regions

Bauernschuster, Stefan; Falck, Oliver; Heblich, Stephan - 2008

This paper tests the importance of social contacts on entrepreneurship. To measure differences in the interconnectedness of social contacts, we compare rural and agglomerated areas. A smaller community size in rural areas generates greater network closure. Agents' neighborhoods are more likely...

From group selection to organizational interactors

Hodgson, Geoffrey M.; Knudsen, Thorbjørn - 2007

This paper builds on previous work within the conceptual framework of a generalized Darwinism that clarifies such concepts as selection and replication. One of its aims is to refine the concept of the interactor. An overview of the conditions under which group selection may occur helps us...

Güth, Werner; Sääksvuori, Lauri - 2010

This article examines the nature of human behavior in a nested social dilemma referred to as the Spillover Game. Players are divided into two groups with positive production interdependencies. Based on theoretically derived opportunistic, local, and global optima, our experimental results...
