Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly misleading...

In consequence, the removal of internal tariff barriers and improved infrastructure strengthened the...

A deranged publisher decided to produce a volume of some of my papers and asked me to write some comments. Since these amount to a summary of my views about international trade theory over the latest forty years or so, I'm giving the comments a separate alternative existence as a discussion paper

Asia and Latin America and the Caribbean (LAC), two regions with large growth potential, have become increasingly connected over the last 20 years. China has emerged not only as a top trading partner, but also as an important competitor of LAC exports. China's retreat from certain markets, due...
