This book presents a representative collection of papers on international trade, one of the most dynamic sub-fields in economics. The contributions range over all the major areas of research, including articles on the geographical aspects of international trade by Paul Krugman and Alan Deardorff, on dynamic stochastic economies by Avinash Dixit, and on endogenous growth by Gene Grossman and Elhanan Helpman. In addition to the theoretical contributions, the book also contains work on important policy issues such as auction quotas, discussed by Kala Krishna, and the role of government in economic development, by Anne Krueger. Also included is an assessment by Bill Ethier of the theoretical achievements of a leading authority in international trade theory, Ronald Jones, in whose honour the essays were written.
