Energy subsidies are an issue in practically every country in the world. Pre-tax subsidies, which arise when energy consumers pay less than the supply cost of energy, are high in many emerging and developing economies, and have risen in recent years. Although pre-tax subsidies are not a large enough problem in advanced economies to cause fiscal difficulties, these countries have tax subsidies, where the taxes imposed on energy are not high enough to account for all of the adverse effects of excessive energy consumption, including on the environment. The issue of energy subsidy reform is not new. Despite widespread recognition of their adverse consequences, energy subsidies have proven difficult to reform. This course builds on an extensive cross-country analysis, which is reported in the recently published IMF book on Energy Subsidy Reform: Lessons and Implications, to make recommendations on how to best implement reforms aimed at reducing state subsidies on energy. In the first part of the course, economists from the IMF will introduce the definition and measurement of subsidies, and then describe the economic, social, and environmental implications of subsidies. The second part of the course has two principal purposes: first, to review what works best in energy subsidy reform, in light of country experiences globally; and second, to illustrate successes and failures in particular country contexts by summarizing some case studies. Whether you are a civil servant working on economic issues for your country or simply interested in better understanding issues related to energy subsidies, this course will provide hands-on training on the design of successful reforms of energy subsidies.
