The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
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.
