This paper discusses the role of sterilized foreign exchange (FX) interventions as a monetary policy instrument for emerging market economies in response to external shocks. We develop a model for a commodity-exporting small open economy in which FX intervention is considered as a balance sheet...

I show that the majority of short-term nominal exchange rate fluctuations among large economies can be explained by changes in the relative stance of their monetary policies. Adapting recently developed instrumental variable techniques for shock identification, I find that monetary policy shocks...

We build a two-country model with imperfect financial intermediation. Banks face limits to arbitrage which lead to positive excess returns in the investment markets and a risk premium in the international credit market. Gross capital flows affect the exchange rate since banks are balance sheet...

This paper examines two approaches characterized by different tail features to extract market expectations on the Mexican peso-US dollar exchange rate. Expectations are gauged by Risk-Neutral Densities (RNDs). The methods used to estimate these densities are the Volatility Function Technique...

The right response to a speculative attack on the domestic currency by monetary authorities in a country with liabilities in US dollars has been a matter of hot debate among academics and policy makers especially after the East Asian Crisis. Using a modified version of the currency crisis model...

Virtual currencies are a contemporary form of private money. Thanks to their technological properties, their global transaction networks are relatively safe, transparent, and fast. This gives them good prospects for further development. However, they remain unlikely to challenge the dominant...

The prospect of central banks issuing digital currency (CBDC) immediately raises the question of how this new form of money should co-exist and interact with existing forms of money. This paper evaluates three different scenarios for the implementation of CBDC in terms of their monetary policy...

This paper revisits the case for flexible vs. fixed exchange rate regime in a two-country model with firm heterogeneity and nominal wage rigidity under incomplete financial markets. Dampening nominal exchange rate fluctuations simultaneously stabilizes the firm turnover in the export market....

One of the main reasons to dollarize an emerging market economy is to eliminate high, persistent, and volatile inflation. To be effective, dollarization must generate sufficient credibility, which in turn depends critically on whether its expected probability of reversal is low. Argentina once...
