Why have countries increasingly restricted immigration even when they have opened their markets to foreign competition through trade or allowed their firms to move jobs overseas? In Trading Barriers, Margaret Peters argues that the increased ability of firms to produce anywhere in the world combined with growing international competition due to lowered trade barriers has led to greater limits on immigration. Peters explains that businesses relying on low-skill labor have been the major proponents of greater openness to immigrants. Immigration helps lower costs, making these businesses more competitive at home and abroad. However, increased international competition, due to lower trade barriers and greater economic development in the developing world, has led many businesses in wealthy countries to close or move overseas. Productivity increases have allowed those firms that have chosen to remain behind to do more with fewer workers. Together, these changes in the international economy have sapped the crucial business support necessary for more open immigration policies at home, empowered anti-immigrant groups, and spurred greater controls on migration. Debunking the commonly held belief that domestic social concerns are the deciding factor in determining immigration policy, Trading Barriers demonstrates the important and influential role played by international trade and capital movements.
