This document analyzes the rationality of keeping international reserves, which are used as a type of insurance in the event of external financing problems and to mediate in the type of exchange rate. Here it is argued that it is not possible to separate both objectives. This explains why the...

The massive stocks of foreign exchange reserves, mostly held in the form of U.S. T-bonds by emerging economies, are still an important puzzle. Why do emerging economies continue to willingly loan to the United States despite the low rates of return? We suggest that a dynamic general equilibrium...

We propose a small open economy model where agents borrow internationally and invest in liquid foreign assets to insure against liquidity shocks, which temporarily shut out the economy of short-term credit markets. Due to the presence of a pecuniary externality individual agents borrow too much...

I establish a theoretical framework to address three distinct, but interrelated puzzles in international economics: (1) the occurrence of twin crises, (2) the existence of large amounts of sovereign debt, and (3) the presence of substantial amounts of international reserves. By considering the...

Purpose - This paper aims to obtain a recent estimate of the cost of precautionary foreign reserve accumulation that emerging market and developing economies (EMDEs) had to endure to protect themselves against the risks of financial globalization. In addition, the study estimates the cost of...

This paper discusses some of the domestic implications of the recent large-scale use of foreign exchange intervention by emerging market economies to resist currency appreciation. Over the past five years, many countries have adopted an accommodating monetary policy while intervening. Despite...

This paper studies from an empirical and theoretical perspective the systemic and bank-level effects of imposing reserve requirements (RR) in foreign currency in an economy with a heavily dollarized financial system. The paper empirically characterizes banks responses to the RR carried out by...

Are capital controls and macroprudential measures desirable in an emerging economy? How do these instruments interact with monetary policy? I address these questions in a DSGE model for an emerging economy whose banks are indebted in foreign currency. The model is augmented with financial...

We estimate international spillover effects of US Quantitative Easing (QE) on emerging market economies. Using a Bayesian VAR on monthly US macroeconomic and financial data, we first identify the US QE shock with non-recursive identifying restrictions. We estimate strong and robust macroeconomic...
