The United States has pledged to become carbon neutral by 2050, meet sectoral objectives (e.g., for carbon free power, electric vehicles) and encourage greater mitigation among large emitting countries and of international transportation emissions. Fiscal policies at the national, sectoral, and international level could play a critical role in implementing these objectives, along with investment, regulatory, and technology policies. Fiscal instruments are cost-effective, can enhance political acceptability, and do not worsen, or could help alleviate, budgetary pressures. Domestically, a fiscal policy package could contain a mix of economy-wide carbon pricing and revenue-neutral feebates (i.e., tax-subsidy schemes) with the latter reinforcing mitigation in the transport, power, industrial, building, forestry, and agricultural sectors. Internationally, a carbon price floor among large emitters (with flexibility to implement equivalent measures) could effectively scale up global mitigation, while levies/feebates offer a practical approach for reducing maritime and aviation emissions.

We discuss and reconcile two diametrically opposed views concerning the future of world oil production and prices. The geological view expects that physical constraints will dominate the future evolution of oil output and prices. It is supported by the fact that world oil production has plateaued since 2005 despite historically high prices, and that spare capacity has been near historic lows. The technological view of oil expects that higher oil prices must eventually have a decisive effect on oil output, by encouraging technological solutions. It is supported by the fact that high prices have, since 2003, led to upward revisions in production forecasts based on a purely geological view. We present a nonlinear econometric model of the world oil market that encompasses both views. The model performs far better than existing empirical models in forecasting oil prices and oil output out of sample. Its point forecast is for a near doubling of the real price of oil over the coming decade. The error bands are wide, and reflect sharply differing judgments on ultimately recoverable reserves, and on future price elasticities of oil demand and supply.

The discussion in this paper of the causes and consequences of recent oil price increases, and the appropriate policy response, is framed by the volatility and uncertainty that characterize the oil market. Volatile prices arise from supply and demand that are both highly inelastic in the short run, with the result that even small shocks can have large effects on price. The difficulty of predicting long-run supply and demand creates uncertainty about future prices. Further, even current supply and demand data are lacking, which results in additional uncertainty. These features of uncertainty and volatility of prices make it difficult to reach simple conclusions about how oil producers and consumers should respond to price changes.

The global trade negotiations and use of fiscal measures to stimulate savings in developing countries are discussed. The four main elements of the global trading system likely to be at issue in the new round include nondiscrimination and the distinction between border and nonborder measures. Capital markets in developing countries are small, and the scope for diversification of financial institutions and financial instruments or assets is limited. The distinction between border and nonborder measures is blurred in the increased international concern with so-called unfair trade practices.
