"Creative and well-researched, Trading Barriers brings together two phenomena that scholars often examine separately: migration and international trade. Peters shows that the liberalization of trade and foreign investment in our globalized world has undercut support for open immigration. In a time of seeming backlash against globalization, this book provides a historical and rigorous empirical explanation of the politics." --Helen Milner, Princeton University "The politics of trade and immigration are typically looked at independently, even though their economic effects are similar. In Trading Barriers , Peters argues that we cannot understand the political economy of trade and the political economy of immigration in isolation from one another. This is a careful, original study of an increasingly important topic that will be of interest to all scholars of international politics and economics." --Jeffry Frieden, Harvard University "Filling a gap in the broad literature on immigration, this masterful book explains why some countries are open to migration at certain times while at others they are closed. It argues that a country's immigration policy occurs not in isolation, but in the same space that trade and capital market policies are determined.

" --David Leblang, University of Virginia "Using systematic data and thoughtful research design strategies, Peters offers a compelling analysis of immigration policy, arguing that policymakers face trade-offs in limiting immigration, firm mobility, and trade barriers. Her book will not only contribute to debates in political economy, but also to larger policy conversations." --William Bernhard, University of Illinois, Urbana-Champaign.
