Mineral-Taxation in a Stages-of-Production Framework

Abstract

Government interference in private markets for exhaustible resources is a ubiquitous phenomenon. Each level of government — federal, state or provincial, and even local — has its own tax policy. Tax-policy instruments include royalties, depletion allowances, severance taxes, price controls and supports, environmental regulations, freight subsidies, profit taxes, and property taxes, to name only a few.These taxes may be levied at every stage of production. For example, property and some ad valorem taxes are levied on ores in the ground, severance taxes are paid when the ore leaves the ground, royalties and depletion allowances may be collected at the first sale (after some degree of processing), and price controls may be placed on finished products.Not only does the government intervene in private resource markets with great regularity but the size of tax effects is not small. For example, depletion allowances in the United States have been as large as thirty three and one third percent of revenues. And price controls in some periods have kept petroleum prices at less than half world prices.
