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

We construct a 45-sector model of Ukraine with Turkey and six other regions to estimate the impacts on Ukraine of deep integration with Turkey in their potential Free Trade Agreement (FTA). Our central model contains foreign direct investment (FDI) in business services with endogenous...

We study the endogenous network formation of bilateral and multilateral trade agreements by means of hypergraphs and introduce the equilibrium concept of multilateral stability. We consider multi-country settings with a firm in each country that produces a homogeneous good and competes as a...
