Isabela Mares (Ph.D., Harvard University, 1999) is Associate Professor of Political Science at Columbia University. Her research and teaching interests include comparative political economy and comparative social policy. She is the author of The Politics of Social Risk: Business and Welfare State Development (Cambridge University Press 2003), which won the Gregory Luebbert Award of the American Political Science Association for the best book in comparative politics. Her book Taxation, Wage Bargaining and Unemployment (Cambridge University Press, 2006) explores the consequences of the growth of the fiscal burden on employment outcomes in advanced industrialized economies. Prior to joining the Columbia Political Science Department in 2006, Professor Mares was Assistant and then Associate Professor of Political Science at Stanford University. While at CSDP, she will focus on a new project on electoral reforms in early 20th century Europe, seeking to develop an account of the variation in the persistence of “imperfections” in voting technology that shaped electoral competition and the electoral disenfranchisement of voters.
