Did the American public become more protectionist during the Great Recession of 2007–09? If so, why? During this period, many observers expressed concern that rising unemployment would stimulate protectionist pressures. The results of this study indicate that although increased unemployment did not affect the trade preferences of most Americans, individuals working in import-competing industries who lost their jobs during the Great Recession did grow more hostile to trade. However, even greater hostility to trade stemmed from a variety of non-material factors. Increasing ethnocentrism and opposition to involvement in world affairs between 2007 and 2009 help account for growing antipathy toward trade. But most importantly, increasing anxiety that foreign commerce would harm people in the future, even if it had not done so thus far, contributed to mounting opposition to trade among the American public.
