This ambitious and impressive book covers the international macroeconomics and finance literature on nominal exchange-rate determination. It will be a useful reference for those who want to understand standard theoretical models and empirical techniques, and for those who want to specialize in the microstructure of the foreign exchange markets."--Pierre-Olivier Gourinchas, University of California, Berkeley"There is no other book of this kind. Sound and interesting, it provides a rigorous treatment of exchange-rate economics. The new concepts and interpretation of exchange-rate behavior will spur more research in this area. The book will interest a broad community in international finance, practitioners in the foreign exchange market, and policymakers."--Lucio Sarno, Cass Business School, City University London
