This paper studies international migration from a complex-network perspective. We define the international-migration network (IMN) as the weighted-directed graph where nodes are world countries and links account for the stock of migrants originated in a given country and living in another...

Factors shaping international migration, over the last half century, from and into the countries and territories of sub-Saharan and North Africa, as well as the economic and some social implications of those movements, are examined. Existing analyses of these issues are critically reviewed,...

The South-North migration corridor, i.e. migration flows to the EU from Africa, the Middle East and EU neighbouring countries in the East, have overtaken the East-West migration corridor, i.e. migration flows from Central and East European countries to the EU15 and the European Free Trade...

This paper investigates through which channels foreign aid impacts migration to donor countries. To disentangle the non-donor-specific channels (development and credit constraint channels) from the donor-specific channels (information and instrumentation channels), we use the fact that...

Have Irish, German or Italian settlers arriving in the US at the turn of the 20th century left an institutional trace which determines economic development differences to this day? Does the national origin of migrants matter for long-term development? This paper explores whether the distinct...

Russia's attacks against Ukraine have triggered massive and unexpected migration movements. In this paper, I examine the impact of the inflow of Ukrainians that resulted from Russia's aggression in 2014 on local migration patterns in Poland. For identification, I use an instrumental variable...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

In this paper we develop a methodology to analyze and compare multiple global networks. We focus our analysis on the relation between human migration and trade. First, we identify the subset of products for which the presence of a community of migrants significantly increases trade intensity. To...
