Several puzzling aspects of the behavior of United States stock prices can be explained by the presence of a specific type of rational bubble that depends exclusively on dividends. We call such bubbles "intrinsic" bubbles because they derive all of their variability from exogenous economic...

Techniques of regulated Brownian motion are used to analyze the behavior of the exchange rate when official policy reaction functions are subject to future stochastic changes. We examine exchange-rate dynamics in alternative cases where the authorities promise (i) to confine a floating rate...

When changes in the economic policy regime occur stochastically, asset prices will reflect the possibility of such shifts. In this paper we apply techniques of regulated Brownian motion to obtain closed-form analytic price solutions when policy reaction functions are subject to prospective...

This paper surveys the decline in real interest rates in advanced and emerging economies over the past several decades, linking that process to a range of global factors that have operated with different force in different periods. The paper argues that estimates of long-run equilibrium real...

The U.S. dollar's nominal effective exchange rate closely tracks global financial conditions, which themselves show a cyclical pattern. Over that cycle, world asset prices, leverage, and capital flows move in concert with global growth, especially influencing the fortunes of emerging and...

Korea's real exchange rate has displayed a mild downward trend since the 1980s, with fluctuations of ±20 percent around that trend. This pattern is surprising because the classic Harrod-Balassa-Samuelson framework suggests that countries experiencing rapid growth in the productivity of their...
