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...

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 paper studies the social and economic responses to the COVID-19 pandemic in a large sample of countries. I stress, in particular, the importance of countries' interconnections to un- derstand the spread of the virus. I estimate a Global VAR model and exploit a dataset on existing social...

Using longitudinal data on immigrants in the Netherlands fromthe survey 'Social Position and Use of Public Facilities by Immigrants' (SPVA) for the years 1991, 1994, 1998, 2002, we examined the impacts of social contacts and Dutch language proficiency on adult foreign-born men's earnings,...

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...

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...

In this paper, we investigate the effect of the level of English skills on the labour market outcomes of Turkish women, using data from the Adult Education Survey of 2007. By adopting a bivariate equation framework, we jointly model the effect of English skills on labour market status and,...

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...
