In a globalized world characterized by huge international capital mobility, there has been renewed interest in international economics in both academic circles and economic policy forums and supranational institutions. The recent financial and economic crisis, in particular, has raised questions concerning the usefulness of several economic paradigms accepted by both academia and advising government institutions. Advances on International Economics offers a broad overview of recent developments in international economics, both theoretical and empirical, adapted from contributions to the XV Conference on International Economics, organized by the Spanish Association of International Economics and Finance (AEEFI), and the University of Salamanca, Spain. The main topics of the contributions to this volume cover modelling international economics, macroeconomic aspects of international trade and finance, international factor movements, and international business. The chapters offer new theories and practical insights through the use of empirical tools for international policy recommendations.
