In this paper we study the question of debt sustainability from a risk management perspective. The debt accumulation equation for any country involves variables that are stochastic and closely intertwined. When these aspects are taken into consideration the notion of debt sustainability is...

This paper examines the welfare implications of managing Q with inflation targeting by monetary authorities who have to "learn" the laws of motion for both inflation and the rate of growth of Q. Our results show that the Central Bank can achieve great success in reducing the volatility of GDP...

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...

We develop an equilibrium model in which exchange rates, stock prices and capital flows are jointly determined under incomplete forex risk trading. Incomplete hedging of forex risk, documented for U.S. global mutual funds, has three important implications: 1) exchange rates are almost as...

The purchasing power parity (PPP) hypothesis has attracted a lot of attention from academics and policy-makers particularly, during the recent float. Most previous studies used data from the developed world. This study examines the validity of the PPP hypothesis using data during the recent...

Previous analytical models focused on the effects of the real exchange rate (RER) and the RER volatility on Chinese aggregate exports. An important and related variable, the RER misalignment, has been hitherto omitted from the analysis. Yet this has been an issue of paramount importance facing...

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...
