Left in the Dark? Oil and Rural Poverty
利用2000-2013年夜间灯光和人口卫星数据衡量农村贫困，发现石油繁荣虽提升全国GDP和照明，但仅惠及城镇，未改善农村贫困，反而加剧区域不平等。
Do oil booms reduce rural poverty and inequality? To study this we measure rural poverty by counting people who live in darkness at night: combining high-resolution global satellite data on night-time lights and population from 2000 to 2013. We develop a measure that accurately identifies 74% of households as above or below the extreme poverty line when compared to over 600,000 household surveys. We find that both high oil prices and new discoveries increase illumination and GDP nationally. However, they also promote regional inequality because the increases are limited to towns and cities with no evidence that they benefit the rural poor.
