Ana Margarida Fernandes is a Senior Economist in the Trade and International Integration Unit of the Development Research Group at the World Bank. She joined the World Bank as a Young Economist in 2002. Her research interests include the consequences of openness to trade and FDI for firm-level outcomes such as productivity, innovation and quality upgrading in manufacturing and services sectors and more broadly the determinants of firm performance, including the role of the business environment. She has also worked on professional services in Africa. Recently her work has been focusing on the one hand on the impact evaluation of trade-related policy interventions (such as export promotion and customs reforms) and on the other hand on exporter growth and dynamics, their links to policies and to development. Since 2011 she has been managing the Exporter Dynamics Database project. She received her M.A. and Ph.D. in Economics from Yale University and holds a B.A. from Universidade Nova de Lisboa, Portugal.
