Environmental Hazards and Local Investment: A Half-Century of Evidence from Abandoned Oil and Gas Wells
研究发现，美国宾夕法尼亚州一个县内未封堵的废弃油气井周围两英亩区域，在半个多世纪里建筑量约为封堵井周围的一半，导致房产价值下降12%。
The United States may have more than 1 million abandoned oil and gas wells that were never properly decommissioned (plugged) and that may be leaking harmful liquids and gases. Exploiting the quasi-random assignment of well plugging in a large county in Pennsylvania, we find that over half a century—and in some cases over a century—the two acres around unplugged wells had roughly half as much building as around plugged wells. Further analysis suggests less local investment rather than shifting within a locality. Forgone investment, in turn, depressed property values by 12%.
