This paper investigates the determinants of school friendship networks among adolescents, proposing a model of network formation and estimating it using a sample (CILS4EU) of about 10,000 secondary school students in four countries: England, Germany, the Netherlands and Sweden. We test the idea...

Academic consensus about normative prescriptions on the ethnic and cultural composition of societies has been shifting in recent decades. It has evolved from what seemed desirable but was acknowledged to be unrealistic (the noble idea of a melting pot), to what is realistic because it has...

In a national ballot in 2009, Swiss citizens surprisingly approved an amendment to the Swiss constitution to ban the further construction of minarets. The ballot outcome manifested reservations and anti-immigrant attitudes in regions of Switzerland which had previously been hidden. We exploit...

This paper identifies a new source of differences in religiosity: the presence of future tense marking in language. We argue that the rewards and punishments that incentivise religious behaviour are less effective for speakers of languages that contain future tense marking. Consistent with this...

This study establishes the influence of sex-based grammatical gender on gendered violence. We demonstrate a statistically significant relationship between gendered language and the incidence of intimate partner violence in a cross-section of countries. Motivated by this evidence, we conduct an...

How do political preferences and voting behaviors respond to information coming from abroad? Focusing on the international migration network, I document that opinion changes at the origins spill over to 1st- and 2nd-generation immigrants abroad. Local diasporas, social media, and family ties to...

How do pandemics affect for-profit and not-for-profit organizations differently? To address this question, we analyze optimal lockdowns in a two-sector continuous-time individual-based mean-field epidemiological model. We uncover a unique solution that depends on network structure, lockdown...

This study develops an economic model for a social planner who prioritizes health over short- term wealth accumulation during a pandemic. Agents are connected through a weighted undirected network of contacts, and the planner's objective is to determine the policy that contains the spread of...

We consider a model of network interactions where the outcome of a unit depends on the outcomes of the connected units. We determine the key network link, i.e., the network link whose removal results in the largest reduction in the aggregate outcomes, and provide a measure that quantifies the...

We examined the impact of the depreciation of the Australian dollar (AU$) during 2013-2015 on the expenditure of households with foreign-born members (HFBMs) in Australia. Employing the difference-in-differences method and 2013-2015 Nielson Homescan Panel Survey data, we found that HFBMs spent...
