This book is a collection of ten essays with discussant commentaries originating from an October 1993 conference at the University of Michigan. Aiming to push international trade theory beyond traditional comparative static analysis, the volume focuses on dynamic modeling, endogenizing trade policy, and analyzing complex interactions among countries, governments, and eco-endogenizing. The collected papers tackle a diverse array of modern economic topics, including complexity theory applied to transport costs and trade structure (Paul Krugman), game-theoretic frameworks examining protectionist lobbying (Gene Grossman and Elhanan Helpman) and results-oriented trade sanctions (Mark Cronshaw and James Markusen), the "Bicycle theory" of gradual trade liberalisation (Robert Staiger), rules of origin as protectionist mechanisms within free trade areas like NAFTA (Kala Krishna and Anne Krueger), technological dynamics and comparative advantage shifts (Michihiro Ohyama and Ronald Jones), and export subsidisation case studies (Dani Rodrik). The title is a stimulating and forward-looking contribution that demonstrates how international trade theory is evolving to address multifaceted real-world challenges.
