Dynamic taxation of non-renewable natural resources under asymmetric information about reserves

Optimal regulation is developed for a case with type-dependent dynamics in costs. In exploiting non-renewable natural resources, a government faces th e problem that extraction companies possess private information about the s ize of the reserves. Optimal contracts, in a two-period framework, distort both the extent and the pace of depletion. The regulatory optimum is implem entable by a menu of tangent planes, generated by licence fees and royaltie s, or by a corporate income tax system containing type-dependent depletion allowances and tax-exempted income levels. If the terminal time is endogeni zed, it is optimal also to distort the number of extraction periods. JEL cl assification: L51, L72.
