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...

Observers have often characterized asset markets as being subject to periods of tranquility and periods of turbulence. Until recently, however, researchers were unable to produce closed-form asset pricing formulas in a model environment of time-varying risk. Some work by Abel provided us with...

This paper analyzes the dynamics of the real exchange rate and the price of equity for a small open economy using an optimizing model in which the process of capital accumulation entails adjustment costs. The analysis demonstrates that along an adjustment path toward long-run equilibrium,...

This paper discusses the estimation of models of the term structure of interest rates. After reviewing the term structure models, specifically the Nelson-Siegel Model and Affine Term- Structure Model, this paper estimates the terms structure of Treasury bond yields for the United States with...

This study analyzes the impact of regional cross-listing of stocks on the depth of the stock markets in sub-Saharan Africa (SSA). It analyzes data from 1990 to 2007 for a panel of 13 stock markets in SSA countries, only some of which have regional cross-listings. Using event study methodology,...

The paper argues that there is a hierarchy of financial markets that reflects the complexity of risks in each market and the interlinkages among markets....

This 2007 Article IV Consultation highlights that Japan’s external position remains strong. Boosted by investment income, the current account surplus widened in 2006 to nearly 4 percent of Japan’s GDP, despite a shrinking trade balance. Financial outflows also picked up, reflecting...

One plausible mechanism through which financial market shocks may propagate across countries is through the effect of past gains and losses on investors'' risk aversion. We first present a simple model on how heterogeneous changes in investors'' risk aversion affect portfolio decisions and stock...

This paper compares the SDR in terms of its risk-return characteristics relative to those of its five components and, on this basis, finds that the SDR has performed favorably over the period under review. In addition, several efficient portfolios including the SDR and its components are...
