Ian Parry is the Principal Environmental Fiscal Policy Expert in the Fiscal Affairs Department of the IMF. Prior to joining the IMF in 2010, Parry held the Allen V. Kneese Chair in Environmental Economics at Resources for the Future where he worked for 15 years. He has a PhD in economics from the University of Chicago in 1993. His PhD thesis, under the supervision of Gary Becker, focused on carbon taxation.
Parry’s current research focuses on country-level analysis of carbon taxes and other policies countries need to implement their mitigation objectives submitted for the 2015 Paris Agreement and the broader fiscal and economic impacts of those policies. He proposes a carbon price floor arrangement among large emitters to scale up global level mitigation. Parry also quantifies the broader environmental (e.g., local air pollution) costs of fossil fuel use at the country level and efficient levels of fuel prices needed to reflect supply and environmental costs. His work is published in academic journals, cross-country reports, and used in technical assistance and IMF bilateral surveillance reports.
