Individuals have a strong tendency to coordinate with all their neighbors on social and economics networks. Coordination is often influenced by intrinsic preferences among the available options, which drive people to associate with similar peers, i.e., homophily. Many studies reported that behind coordination game equilibria there is the individuals' heterogeneity of preferences and that such heterogeneity is given a priori. We introduce a new mechanism which allows us to analyze the issue of heterogeneity from a cultural evolutionary point of view. Our framework considers agents interacting on a multiplex network who deal with coordination issues using social learning and payoff-driven dynamics. Agents form their heterogeneous preference through learning on one layer and they play a pure coordination game on the other layer. People learn from their peers that coordination is good and they also learn how to reach it either by conformism behavior or sorting strategy. We find that the presence of the social learning mechanism explains the rising and the endurance of a segregated society when members are diverse. Knowing how culture affects the ability to coordinate is useful for understanding how to reach social welfare in a diverse society.

“…Blume (1993) and Ellison (1993) drew attention to the role of interaction structures in shaping coordination, while Goyal and Vega-Redondo (2005) and Jackson and Watts (2002) developed models in which players choose partners and also actions in a coordination game. In more recent years, a number of researchers have introduced heterogeneity of preferences in these models as a way to think about culture and identity, see e.g., Advani and Reich (2015), Bojanowski and Buskens (2011), and Ellwardt et al (2016) and Neary (2012). Our paper conducts an experimental investigation on the role of endogenous linking in such a setting.…”

We study a setting where individuals prefer to coordinate with others but they differ on their preferred action. Our interest is understanding the role of linking in shaping behavior. So we consider the situation in which interactions are exogenous and a situation where individuals choose links that determine the interactions. Theory is permissive in both settings: conformism (on either of the actions) and diversity (with different groups choosing their preferred actions) are both sustainable in equilibrium. Our experiments reveal that, in an exogenous complete network, subjects choose to conform to the majority's preferred action. By contrast, when linking is free and endogenous, subjects form dense networks (biased in favour of linking within same preferences type) but choose diverse actions. The convergence to diverse actions is faster under endogenous linking as compared to the convergence to conformity on the majority's preferred action under the exogenous complete network. Thus our experiments suggest that individuals use links to resolve the coordination problem.

“…Goyal and Vega-Redondo [2005] and Jackson and Watts [2002] developed models in which players choose partners and also actions in a coordination game. In recent work, Advani and Reich [2015], Bojanowski and Buskens [2011] and Ellwardt et al [2016] introduce heterogeneous preferences in the framework with partner choice and action choice. There is also a strand of work on the role of endogenous interactions in cooperation, see e.g., Wang et al [2012], Gallo and Yan [2015], Cuesta et al [2015].…”

Individuals prefer to coordinate with others, but they differ on the preferred action. In theory, this can give rise to an integrated society with everyone conforming to the same action or a segregated society with members of different groups choosing diverse actions. Social welfare is maximum when society is integrated and everyone conforms on the majority's action. In laboratory experiments, subjects with different preferences segregate into distinct groups and choose diverse actions. To understand the role of partner choice, we then consider an exogenous network of partners. Subjects in the experiment now choose to conform on the action preferred by the majority. Thus, there exists a tension between two deeply held values: social cohesion and freedom of association.
