"The Oxford Handbook of the Political Economy of International Trade" explores various aspects of international trade, including its historical origins, effects, and policy instruments. The researchers delve into how individual attitudes, domestic politics, and firms influence trade policies. They also examine the role of domestic institutions, international negotiations, and issue linkages in shaping global trade dynamics. Key findings include the impact of labor sentiment on protectionism, the influence of industry-level protection on trade outcomes, and the connection between trade agreements and dispute settlement. Additionally, the researchers highlight the interplay between trade and issues like war, environment, development, human rights, and migration in the global economy.
