Vertically summing public good demand curves: An empirical comparison of economic versus political jurisdictions

Fiscal equivalence for efficient provision of a public good requires perfec t correspondence between political and economic jurisdictions. However, the spatial extent of the economic jurisdiction is ail empirical question. Dra wing on forts survey-based valuation studies, we measure the "relative publ ic good benefit gradient" as a function of residential location from six na tural resource public goods. The results indicate commonly used state polit ical jurisdictions reflect an average of 13% of total benefits in the econo mic jurisdiction, although with a logarithmic form for distance the upper c onfidence interval of state benefits can include 100% for some species.(JEL H41; D61)
