The mortgaging of land is not just economic and legal but also social and cultural. Here, anthropologists, historians, and economists explore origins, variations, and meanings of the land mortgage, and the risks to homes and livelihoods. Combining findings from archives, printed records, and live ethnography, the book describes the changing and problematic assumptions surrounding mortgage.  It shows how mortgages affect people on the ground, where local forms of mutuality mix with larger bureaucracies. The outcomes of mortgage in Africa, Europe, Asia, and America challenge economic development orthodoxies, calling for a human-centered exploration of this age-old institution.
