Take Me Home, Country Roads: Historical Diasporas and Contemporary FDI Patterns

open access: yesThe World Economy, EarlyView.
ABSTRACT We examine whether historical diasporas shape current foreign direct investment (FDI) flows, using Italian data from the ‘age of mass migration’ (1876–1925). We find that Italian regions with larger diasporas at the turn of the twentieth century maintain persistent economic ties with their historical destinations.

The Invisible Risks of Extractive Infrastructure Networks and Mining

open access: yesVisual Anthropology Review, EarlyView.
Abstract This article uses Actor‐Network Theory to analyze mining infrastructures in Chile and develop a concept of “extractive infrastructure networks.” Focusing on the port of Punta Chungo and its connection to the Los Pelambres mine, we explore how these infrastructures, along with human and non‐human actors, create networks that sustain the ...
