美国野火扑救的经济归宿

This study measures the degree to which public expenditures on wild-fire protection subsidize development in harm’s way. We use administrative data on firefighting expenditures to measure the causal effect of nearby homes on the amount spent to extinguish wildfires. We use these estimates in an actuarial calculation yielding geographically differentiated expected implicit subsidies for homes across the western United States. The expected net present value of this subsidy can exceed 20 percent of home value, increases with fire hazard, and decreases surprisingly steeply with development density. We discuss potential behavioral responses by individuals and local governments using a simple economic model. (JEL D91, Q23, Q54, R52, R58)
