Pierre-Philippe Combes is a CNRS Professor in the department of economics at Sciences Po, Paris. He is also a Research Fellow at the Centre for Economic Policy Research (CEPR). His research interests are in urban economics and economic geography, with a special focus on the working of local labour and housing markets and the location choices of firms and households, resulting in possible economic spatial disparities. With co-authors, he's currently developing a programme on urbanisation over time, since the 18th c. Most of his papers regard the French economy but a recent series focuses on China. His work is regularly published in the top, international, peer-reviewed journals in economics, such as Econometrica, the Review of Economic Studies, the Journal of Political Economy, or the Journal of the European Economic Association, as well as in specialised reviews such as the Journal of Urban Economics, the Journal of International Economics, the Journal of Labor Economics, and the Journal of Development Economics. He is a co-editor of the Journal of Urban Economics. His personal webpage.
