Savings at the Periphery of Markets: Evidence from Forager-Farmers in the Bolivian Amazon
基于调查和民族志数据，研究玻利维亚亚马逊地区高度自给自足的Tsimane’人的储蓄行为，发现储蓄量年际变化不大，原因包括低收入、冲动性以及借贷、盗窃和互惠规范等制度与习俗的捆绑效应。
We used survey and ethnographic data to study savings in a highly autarkic society of native Amazonians in Bolivia (Tsimane’). We equated savings with the amount of maize and rice in storage, area planted with plantains and manioc, and number of edible domesticated animals owned by a household or an adult. We found no large inter-annual change in savings possibly due to low income, impulsivity and a bundle of institutions and norms, such as borrowing, theft and reciprocity norms. The bundle attenuates the need for household formal savings at the periphery of markets.
