Addressing the infrastructural, social and legal complexities of a global commodity chain, this book uses an ethnographic analysis of the encounter between multinational corporations and popular traders in the Bolivian Andes. It offers a situated account of the everyday work of chain (un)making, and practices of translation, accommodation and contention. It highlights traders' collective action, understanding of economic concepts and regulatory principles, and traces the circulation of goods and money beyond market exchange. All in all, it aims to comprehend the reproduction of the native trading system amid global connections, and to humanize our understanding of the economy by grounding it in everyday life, bottom-up socio-material infrastructures and morality.
