We experimentally disentangle two potential sources for endogenous social interactions effects. By comparing groups where the group norm is publicly observable with those where it is not we can measure the size of any endogenous observation effect. By comparing connected with disconnected groups...

History teaches that discrimination against socially undesirable groups leads to societal and governmental neglect of the stigmatized group’s health problem. By placing weight discrimination in a historical context, this article demonstrates that legislation specifically aimed at rectifying...

We analyze how the share of immigrant children in the classroom affects the educational attainment of native Dutch children in terms of their language and math performance at the end of primary school. Our paper studies the spill-over effects at different parts of the test score distribution of...

We study the existence of homophily (i.e. the tendency for people to make friends with people who are similar to themselves) with respect to trustworthiness. We ask whether two friends show similarly trustworthy behavior towards strangers, and whether this is anticipated by outsiders. We develop...

In a laboratory experiment, we explore the effects of group identities on the principal-agent relationship between voters and representatives. In an adverse selection framework with observable effort, voters can choose to condition their re-election choices on representatives' effort alone,...

This paper investigates the impact of peer observation on the consumption decisions of rural households in Thailand using a lab-in-the-field experiment. We find that those groups that observe each other show lower within group standard deviation in their decisions. Thus, we find evidence for...

This paper extends the standard work effort model by allowing workers to interact through networks. We investigate experimentally whether peer performances and peer contextual effects influence individual performances. Two types of network are considered. Participants in Recursive networks are...

The main challenges in estimating strategic network formation models are the presence of multiple equilibria, and the fact that the number of possible network configurations increases exponentially with the number of players. I propose a dynamic model of strategic network formation with...

How do consumers reconcile conflicting motives for social group identification and individual uniqueness? Four studies demonstrate that consumers simultaneously pursue assimilation and differentiation goals on different dimensions of a single choice: they assimilate to their group on one...

Utilizing a sample of 3,211 Chinese listed firm-years during COVID-19 crisis, this paper empirically tests the industry peer effect of charity giving. Our empirical results show that a higher amount of donation at the industry level significantly promotes a Chinese listed firm’s potential and...
