We build a minimalist model of the macroeconomics of a pandemic, with two essential components. The first is productivity-related: if the virus forces firms to shed labor beyond a certain threshold, productivity suffers. The second component is a credit market imperfection: because lenders...

We study the interaction between optimal foreign reserves accumulation and central bank international liquidity provision in a small open economy under financial stress. Firms and households finance investment and consumption by borrowing from domestic financial intermediaries (banks), which in...

In recent years, large fluctuations in world food prices have renewed interest in the question of how monetary policy in small open economies should react to imported price shocks. We address this issue in an open economy setting similar to previous ones except that food plays a distinctive role...

This paper reviews the recent experience of a half-dozen Latin American inflation-targeting (IT) nations. We document repeated and large deviations from the standard IT framework: exchange market interventions have been lasting and widespread; the real exchange rate has often become a target of...

We develop a dynamic model of a small open economy that trades commodities whose world prices are subject to realistic random fluctuations, and study the implications of monetary policy alternatives. The model is much more flexible than those of previous studies, especially in allowing to...

This paper develops an open economy model in which financial intermediation is subject to occasionally binding collateral constraints, and uses the model to study unconventional policies such as credit facilities and foreign exchange intervention. The model highlights the interaction between the...

The Covid-19 pandemic has motivated a myriad of studies and proposals on how economic policy should respond to this colossal shock. But in this debate it is seldom recognized that the health shock is not entirely exogenous. Its magnitude and dynamics themselves depend on economic policies, and...

I study a small open economy in which elections affect and are affected by capital inflows. Two candidates, one favoring workers and another favoring entrepreneurs, run for office; the winner chooses taxes, which affect investment returns. A pro labor victory results in a quot;sudden stopquot; in...

This paper is an analysis of the simultaneous determination of financial default and political crises and its consequences. It focuses on a small open economy that faces a debt default decision. Crucially, this decision is made by a government that has superior information than the public about...

A country's financial system is internationally illiquid if its potential short term obligations in foreign currency exceed the amount of foreign currency it can have access to in short notice. This condition may be crucial for the existence of financial crises and/or exchange rate collapses...
