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

Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known -- and traditionally presumed exogenous -- “trade-cost elasticity” plays a central role in computing general equilibrium trade-flow...

We use a quantitative model to study the implications of European integration for welfare and migration flows across 1,318 regions. The model suggests that an increase of trade barriers to the level of 1957 reduces welfare by about 1-2 percent on average, depending on the presumed trade...

The goal of this investigation is to research the development of intensive and extensive trade margins on product-country level data for Croatia during the period 2000–2012. Hypothesis of our paper is that RTAs-induced trade liberalization will have heterogeneous effects on particular product...
