Oil, gas and mineral deposits are a substantial part of the wealth of many countries, not least in developing and emerging market economies. Harnessing some part of that wealth for fiscal purposes is critical for economic development: in few areas of economic life are the returns to good policy so large, or mistakes so costly.

This paper examines the environmental effects of mineral taxes in a framework that recognizes the importance of rates and cumulative externalities and proposes an appropriate corrective tax. It concludes that mineral resources taxation should combine neutral taxes with a dynamic Pigovian type tax proposed in the paper. Such a tax resembles a specific tax plus an element that depends on the amount of remaining reserves. This resemblance means that, in practice, specific taxes may act as proxies for environmental taxes. The paper also points at complementarities and tradeoffs between economic and environmental concerns that could arise in reforming mineral taxes.

Better designed and implemented fiscal regimes for oil, gas, and mining can make a substantial contribution to the revenue needs of many developing countries while ensuring an attractive return for investors, according to a new policy paper from the International Monetary Fund. Revenues from extractive industries (EIs) have major macroeconomic implications. The EIs account for over half of government revenues in many petroleum-rich countries, and for over 20 percent in mining countries. About one-third of IMF member countries find (or could find) resource revenues “macro-critical” – especially with large numbers of recent new discoveries and planned oil, gas, and mining developments. IMF policy advice and technical assistance in the field has massively expanded in recent years – driven by demand from member countries and supported by increased donor finance. The paper sets out the analytical framework underpinning, and key elements of, the country-specific advice given. Also available in Arabic: ????? ??????? ?????? ???????? ???????????: ??????? ????????
