This paper investigates implications of nominal rigidities for the risk premium. We use Obstfeld and Rogoff (1998) type DSGE model equipped with nominal rigidities, imperfect market competitions, a production sector, and a money-in-the-utility function. For a monthly frequency, we generate...

If country and currency risk premiums are positively correlated, a negative international liquidity shock harms twice the economy, thereby substantially increasing interest rates. This harmful positive correlation between country and currency risk premiums observed in some countries is called...

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...

Collective action clauses (CACs) are provisions specifying that a supermajority of bondholders can change the terms of a bond. We study how CACs determine governments’ fiscal incentives, sovereign bond prices and default probabilities in environments with and without contingent debt and...

This paper presents a simple model of debt contracts in order to analyze the conditions under which domestic residents would choose to denominate debts in ``dollars''. In the model, borrowers are producers of non-traded goods, and subject to shocks on prices. The real exchange rate varies 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...

This article analyzes the specifications of option pricing models based on time-changed Levy processes. We classify option pricing models based on (i) the structure of the jump component in the underlying return process, (ii) the source of stochastic volatility, and (iii) the specification of...

In this paper, we relate security returns in the thirty securities in the Dow Jones index to regime shifts in the market portfolio (S&P500) volatility. We model market volatility as a multiple-state Markov switching process of order one and estimate non-diversifiable security risk (beta) in the...

The importance of currency and maturity mismatches in the debt structure of emerging markets is an issue that can hardly be overemphasized. Yet, while many papers have explained how imbalances in the asset and liability structure of emerging markets can cause currency and financial crises, the...
