This chapter surveys empirically the broad features of trade policy in goods for 31 major economies that collectively represented 83 percent of the world's population and 91 percent of the world's GDP in 2013. We address five questions: Do some countries have more liberal trading regimes than others? Within countries, which industries receive the most import protection? How do trade policies change over time? Do countries discriminate among their trading partners when setting trade policy? Finally, how liberalized is world trade? Our analysis documents the extent of cross-sectional heterogeneity in applied commercial policy across countries, their economic sectors, and their trading partners, over time. We conclude that substantial trade policy barriers remain as an important feature of the world economy.
AbstractThis chapter surveys empirically the broad features of trade policy in goods for 31 major economies that collectively represented 83 percent of the world's population and 91 percent of the world's GDP in 2013.

How do trade policies change over time? Do countries discriminate among their trading partners when setting trade policy? Finally, how liberalized is world trade?

High income countries have more liberal regimes than middle income countries which, in turn, have more liberal regimes than low income countries. To this broad picture we add two more subtle observations. High income countries appear even more open when we expand the set of policies to include preferential tariffs on imports that they offer to selected trading partners. On the other hand, both high income and emerging economies appear less open when we expand the set of policies beyond tariffs to include policies such as temporary trade barriers and quantitative restrictions.Question 2: Within countries, which industries receive the most import protection?With respect to import tariffs, agricultural products and foodstuffs are protected almost everywhere, regardless of a country's level of development. Textiles, apparel and footwear are more protected than other manufactured goods. Minerals and fuels tend to face few import barriers.Furthermore, import tariffs on final goods are higher than t...
