Research has shown that the unilateral accumulation of international reserves by a country can improve its own macro-financial stability. However, we show that when many countries accumulate reserves, the induced general equilibrium effects weaken financial and macroeconomic stability,...

When available financial securities allow investors to optimally diversify risk across countries, standard theory implies that exchange rates should reflect this behavior. However, exchange rates observed in the data deviate from these predictions. In this paper, we develop a framework to value...

We revisit a central question for international macroeconomics: the response of export prices and quantities to movements in the exchange rate (ER). We use granular export data for Chile and study how the effects of ER movements vary over time with the currency of invoicing and the destination...

We use a general open-economy wedge-accounting framework to characterize the set of shocks that can account for major exchange rate puzzles. Focusing on a near-autarky behavior of the economy, we show analytically that all standard macroeconomic shocks -- including productivity, monetary,...

This paper finds that limited exchange rate flexibility in the form of "fear of appreciation" significantly slows adjustment of current account imbalances, providing novel support for Friedman's conjecture regarding exchange-rate flexibility. We present a new stylized fact: floaters have faster...

Foreign investors' changing appetite for risk-taking have been shown to be a key determinant of the global financial cycle. Such fluctuations in risk sentiment also correlate with the dynamics of UIP premia, capital flows, and exchange rates. To understand how these risk sentiment changes...

We study international trade and macroeconomic dynamics triggered by the imposition of sanctions. We begin with a tractable two-country model where Home and Foreign countries have comparative advantages in production of differentiated consumption goods and a commodity (e.g., gas), respectively....

While substantial empirical research has evaluated the question of whether capital account openness promotes economic growth, this paper finds empirical evidence for cases where the opposite is true--that a policy of capital controls can promote economic growth, when combined with a policy of...
