This volume collects selected papers on the European Union from the 13th Congress of the International Economic Association held in Lisbon, September 2002. It starts with an address by Romano Prodi, President of the European Commission, who sets the tone for the other papers by describing and evaluating two of the greatest accomplishments of the EU: economic and monetary union, and EU enlargement. Other authors deal in detail with various aspects of these and other issues, using a mixture of theoretical, empirical, and other tools.
