Between in-group selection and economic interdependence: Field experiments on prosocial behavior in a multiethnic society
Baldassarri poster

How does prosocial behavior extend beyond in-group boundaries in multiethnic societies? Recent waves of immigration in Western societies have led scholars to conclude that ethnic heterogeneity undermines trust, social capital, and collective goods provision. However, the type of prosociality that helps heterogeneous societies function is different from the in-group solidarity that glues homogeneous communities together. The interdependence and division of labor of life in contemporary urban settings often forces people outside the comfort zones of their familiar networks to constructively interact with unknown, diverse others. Using a large-scale lab-in-the-field experiment with representative sample of Italian natives and immigrants from the metropolitan city of Milan, we study behavior toward coethnics and non-coethnics in strategic and non-strategic interactions. We find that when given the opportunity to select their interaction partners, Italians favor coethnics over immigrants. However, when forced to interact with non-coethnics, as it happens in many economic transactions, Italians generally treat them similarly to how they treat coethnics. They also value signs of social and market integration. Taken together, these results contribute to make sense of the persistence of discriminatory behavior toward minorities in selection processes, as well as confirm contact theory intuition that interaction with outgroup members, especially when individuals have common goals and equal status in the interaction, is likely to foster prosociality.

When Content is King: Using Topic Models to Analyze Online Innovation Crowdsourcing at IBM
DiMaggio poster

Over the past twenty years, a major development in firms’ innovation strategies has been the emergence of crowdsourcing as a tool to stimulate new ideas. A growing literature has examined the process by which ideas are winnowed from such discussions for further develop¬ment. This talk focuses upon a surprisingly neglected factor: the substantive content of em¬ploy¬ee interventions. We demonstrate the utility of topic modeling as an approach to extracting thematic information about discussion content and serving as a basis for identifying significant collective concerns and the degree of consensus around them, the alignment of posts with both elite and consensus emphases, and evidence for deliberative learning during discussion threads. We use this approach to analyze an influential example of such discussions and demonstrate that posts selected to exemplify promising ideas for innovation emphasized particular themes, were aligned with cues from organizational elites as well as reflecting broader topical emphases, and were both generative of and influenced by relatively long ex¬changes. Finally, we consider feat¬ures of the discussion design and selection process that may have accounted for the results we report.

A sociological analysis of the UK’s global elite: evidence from tax records
Summers poster

The UK has proved an attractive destination for the world’s top earners and high net wealth individuals. In 2017, around one quarter of the top 1% by income originally came from abroad, rising to one third amongst the top 0.1% and to nearly four in ten of those within the top 0.01%. Although many of these migrants settle permanently, the UK offers a special tax regime to those who maintain foreign connections, who are known as ‘non-doms’ (i.e. individuals not domiciled in the UK). In the popular imagination, non-doms epitomise a globalised economic elite, simultaneously exerting significant influence within British society, yet remaining weakly tied to the place where they live. We use administrative tax data covering every individual who claimed ‘non-dom’ status from 1997-2017 to provide the first sociological anatomy of this enigmatic group. We will present our initial findings on their national origins and the neighbourhoods within which they live, allowing us to explore the non-dom population on scales from the global down to local. We will also outline an agenda for further work on the sociology of elites in the UK.
