Natural Resources and Local Communities: Evidence from a Peruvian Gold Mine
利用1997-2006年秘鲁北部金矿的年度家庭数据，研究发现该矿对本地投入的需求提高了实际收入，但仅体现在供应市场和周边地区，并惠及非采矿部门的非熟练工人，同时推高了非贸易品价格。
This paper examines the local economic impact of Yanacocha, a large gold mine in Northern Peru. Using annual household data from 1997 to 2006, we find evidence of a positive effect of the mine's demand for local inputs on real income. The effects are only present in the supply market and surrounding areas, and reach unskilled workers in non-mining sectors. Consistent with a general equilibrium framework, we also find an increase in the local price of nontradable goods. Taken together, our results underline the potential of backward linkages from extractive industries to create positive spillovers in less developed economies.
