We study how friendship shapes students' political opinions in a natural experiment. We use the indicator whether two students were exogenously assigned to a short-term \integration group", unrelated to scholar activities and dissolved before the school year, as instrumental variable for their...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

We investigate to what extent tolerance, as measured by attitudes toward different types of neighbors, affects economic growth. Data from the World Values Survey enables us to investigate tolerance–growth relationships for 54 countries. We provide estimates based on cross-sectional as well as...

Tolerance has the potential to affect both economic growth and wellbeing. It is therefore important to discern its determinants. We add to the literature by investigating whether the degree to which economic institutions and policies are market-oriented is related to different measures of...

Tolerance is a distinguishing feature of Western culture: There is a widespread attitude that people should be allowed to say what they want even if one dislikes the message. Still, the degree of tolerance varies between and within countries, as well as over time, and if one values this kind of...

In a comment to Dahlberg, Edmark and Lundqvist (2012), Nekby and Pettersson-Lidbom (2012) argue (i) that the refugee placement program should be measured with contracted rather than actually placed refugees, and claim that the correlation between the two measures is insignificant and close to...

I establish a positive relationship between family ties and civic virtues, as captured by disapproval of tax and benefit cheating, corruption, and a range of other dimensions of exploiting others for personal gain. I find that family ties are a complement to social capital, using within country...

Edmund Phelps, the 2006 Nobel Laureate in Economics, has written a thought-provoking and ambitious book: Mass Flourishing: How Grassroots Innovation Created Jobs, Challenge, and Change (Princeton University Press, 2013). The book is laudable for its emphasis on innovation, for its discussion of...

Tolerance – respecting those who are different – is arguably of particular importance in an era of globalization, where a potential for economic, social and personal development is increasingly a function of interaction with others different from oneself. We investigate whether globalization...

We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...
