While the resulting localized economic effects are relatively well understood, less is known about the geographic dispersion of the effects. We build upon an existing literature, most notably Feyrer, Mansur, and Sacerdote (2017), by examining the conditional economic effects of nearby energy production. Because energy-producing counties tend to be located near each other, producing counties experience inward economic spillovers from other nearby producing counties and this inflates the estimated effect of own-county production. Accounting for this, we identify smaller income effects of hydrocarbon production than Feyrer, Mansur, and Sacerdote (2017), limited to counties within 60-80 miles of the source of production. The proposed estimation strategy can be applied more generally to estimate the dispersion of multiple, simultaneously occurring economic shocks.
