title: Geographic Dispersion of Economic Shocks: Evidence from the Fracking Revolution
abstract: The combining of horizontal drilling and hydrofracturing unleashed a boom in oil and natural gas production in the US. This technological shift interacts with local geology to create an exogenous shock to county income and employment. We measure the effects of these shocks within the county where production occurs and track their geographic propagation. Every million dollars of oil and gas extracted produces $66, 000 in wage income, $61, 000 in royalty payments, and 0.78 jobs within the county.
