I construct a micro-model to show that a currency crisis can spread from one country to another even when these countries are unrelated in terms of economic fundamentals and there is no capital linkage across countries through a common lender or an interbank market. The key to explaining...

This paper studies the implications of the presence of a large speculator like George Soros during a contagious currency crisis. The model proposes a new contagion channel and shows how a currency crisis can spread from one country to another even when these countries are totally unrelated in...

Abstract Recent financial crises showed that emerging countries are extremely vulnerable to sudden swings in international capital flows. In these countries, commonly, periods of relative tranquility, characterized by substantial capital inflows and real GDP growth, are followed by periods when...

This paper proposes a model encompassing alternative views of contagion by highlighting the different channels of transmission of financial crises in an unifying framework. We study investor behaviour when they are affected by external habit formation. It is shown how international portfolio...

Using the tick-by-tick yen/dollar exchange rate, this paper examines the effect of Japanese banking crisis in late 1997 on the foreign exchange market. By high-frequency methodology, GARCH estimation and variance-ratio tests, the existence of a structural break in the foreign exchange market at...

This paper tests for the martingale (or random walk) hypothesis in the stock prices of a group of Asian countries. The selected countries represent well-developed markets (Hong Kong and Japan) as well as emerging markets (Korea, Taiwan and Thailand). This paper adopts a new joint variance ratio...

This paper shows that the Mexican experience from 1945 to 2002 is, like the German hyperinflation period, a unique monetary ``natural experiment,'' where fundamental relationships, like money demand, PPP and the monetary model of exchange rate determination can be analyzed with unparalleled...

Empirical evidence shows that macroeconomic fundamentals have little explana-tory power for nominal exchange rates. On the other hand, the recent “microstruc-ture approach to exchange rates” has shown that most exchange rate volatility at short to medium horizons is related to order flows....

We present a new class of general equilibrium model to study exchange rate dynamics. Our model synthesizes the new micro and macro approaches by incorporating the micro foundations of asset market trading into a dynamic, two country general equilibrium setting. We use the model to study how...

This paper develops a simple two-country, two-good model, in which the real exchange rate, stock and bond prices are jointly determined. The model predicts that stock market prices are correlated internationally even though their dividend processes are independent, providing a theoretical...
