Redistributional Effects of the National Flood Insurance Program

Abstract

This study examines the redistributional effects of the National Flood Insurance Program (NFIP) using a national database of premium, coverage, and claim payments at the county level between 1980 and 2006. Measuring progressivity as the departure from per capita county income proportionality we find that NFIP premiums are weakly regressive on an annual basis but become proportional as the time horizon is extended beyond a single year. In contrast, we find that NFIP claim payments are moderately progressive over all time horizons studied. In sum, we find no evidence that the NFIP disproportionally advantages richer counties.NFIP, progressivity, departure from proportionality
