In most macroeconomic models, the substitutability between domestic and foreign goods is calibrated using aggregated data. This imposes homogeneous elasticities across goods, and the calibration is only valid under this assumption. If elasticities are heterogeneous, the aggregate substitutability is a weighted average of good-specific elasticities, which in general cannot be inferred from aggregated data. We identify structurally the substitutability in US goods using multilateral trade data. We impose homogeneity, and find an aggregate elasticity similar in value to conventional macroeconomic estimates. It is more than twice larger with sectoral heterogeneity. We discuss the implications in various areas of international economics.

"This book deals with the financial side of international economics and covers all aspects of international finance. There are many books and articles by exponents of alternative points of view. I know of no other book that provides the scope, balance, objectivity and rigor of the book." (Professor Jerome L. Stein, Brown University) From the reviews: "In this survey of international finance and open-economy macroeconomics, Gandolfo succeeds in meeting the needs of advanced undergraduate or lower-level graduate students through a largely textual and graphical approach, while at the same time presenting in the appendices explicit mathematical analyses for more advanced graduate students."

This is a collection of independent works on the GLOBUS model. A first and basic application of the GLOBUS model was made through the computation of its standard run for the years 1970-2010. Stated in the simplest possible terms GLOBUS is a computer simulation model of many important macropolitical and macroeconomic relationships within and among 25 prominent contemporary nations plus a rest-of-world entity. It is designed and used to explore possible solutions to long-term global problems.

This report provides alternative views of how large a dollar depreciation would be needed to restore a sustainable position; analyzes the impact of currency misalignments on each of the three major economies; and discusses the role of exchange market intervention in addressing the issues.

During the so-called Great Moderation the variability of output, employment and inflation declined substantially in most of the major economies. Because of this positive co-movement the ultimate objective of monetary policy was clear. By stabilizing inflation output will also stay at its potential and the central bank does not face any trade-off between its targets – a situation known as the divine coincidence. With the onset of the financial crisis 2007 these relationships changed. This book contributes to the research on the optimal macroeconomic policy design in the presence of financial frictions. These are incorporated via the cost channel approach into a two-country currency union model. Ultimately, a supply-side effect arises which lowers the efficiency of monetary policy - divine coincidence is not possible any more. Three questions are in the focus of interest of this analysis: What is the optimal monetary policy in the presence of country-specific financial frictions? What role can fiscal policy play? Is macroprudential policy able to improve welfare if the central bank targets a financial stability measure?
