The economic analysis of international law is a field of research which is still very new but which for several years has been growing and become extremely promising. For this reason the organizers of the XIVth Travemunde Symposium on the economic analysis of law decided for the second time to bring together economists and jurists from Europe and non-European countries in order to discuss some of those problems of international law which are still unsolved. The articles resulting from this, published in this volume, discuss how natural disasters, civil wars or economic collapses affect international law and how international law deals with these extreme conditions.
