In provinces endowed with natural resources, revenue from those
resources is often shared with the municipalities. Specifically, royalties on oil,
gas, and hydroelectricity, typical of Argentine Patagonia and the western
provinces, are shared with the provinces. The hydrocarbon royalties are
shared at variable rates.Two provinces, La Pampa and Formosa, do not share
this resource with municipalities, however. Hydroelectric royalties are not
shared with local governments, except in Mendoza and Entre Ríos
