This paper provides the first direct evidence on the determinants of link formation among immigrants in the host society. We use a purposely-designed survey on a representative sample of Sri Lankan immigrants living in Milan to study how migrants form social links among them and the extent to...

This paper employs a weighted network analysis to study the empirical properties of the world trade web and their evolution over time. We show that most countries are characterized by weak trade links; yet, there exists a group of countries featuring a large number of strong relationships, thus...

Over the past four decades the High Performing Asian Economies (HPAE) have followed a development strategy based on the exposure of their local markets to the presence of foreign competition and on an outward oriented production. In contrast, Latin American Economies (LATAM) began taking steps...

We use a purposely-designed survey on Sri Lankan immigrants living in Milan to study their personal network. By taking a dyadic perspective we investigate how migrants form (weak and strong) social links among them in the host country, and the extent to which this network provides them material...

Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this paper, we investigate how social norms affect individual effort, aggregate effort, and welfare. While individual productivity always positively...

Although the linear-in-means model is the workhorse model in empirical work on peer effects, its theoretical properties are understudied. In this study, we develop a social-norm model that provides a microfoundation of the linear-in-means model and investigate its properties. We show that...
