Sudden Stops and Optimal Foreign Exchange Intervention
This paper shows how foreign exchange intervention can be used to avoid a sudden stop in capital flows in a small open emerging market economy. The model is based around the concept of an under-borrowing equilibrium defined by Schmitt-Grohe and Uribe (2020). With a low elasticity of substitution between traded and non-traded goods, real exchange rate depreciation may generate a precipitous drop in aggregate demand and a tightening of borrowing constraints, leading to an equilibrium with an inefficiently low level of borrowing. The central bank can preempt this deleveraging cycle through ...

A model of the Twin Ds: optimal default and devaluation
This paper characterizes jointly optimal default and exchange-rate policy in a small open economy with limited enforcement of debt contracts and downward nominal wage rigidity. Under optimal policy, default occurs during contractions and is accompanied by large devaluations. The latter inflate away real wages, thereby avoiding massive unemployment. Thus, the Twin Ds phenomenon emerges endogenously as the optimal outcome. In contrast, under fixed exchange rates, optimal default takes place in the context of large involuntary unemployment. Fixed-exchange-rate economies are shown to have ...

Financial market reactions to the Russian invasion of Ukraine
This article analyzes financial market reactions to the Russia-Ukraine war with a focus on the opening weeks. Markets did not completely anticipate the war and asset price reactions strengthened from the first week—when there were hopes for a quick resolution—to the second week, when prices generally peaked and began to partially revert to pre-war values. Exposure to commodity trade and trade with Russia-Ukraine determined market perceptions of the riskiness of equity and foreign exchange assets. Credit default swap prices on sovereign debt and breakeven inflation rates indicate that ...

The Impact of Bretton Woods International Capital Controls on the Global Economy and the Value of Geopolitical Stability: A General Equilibrium Analysis
This paper quantifies the positive and normative impacts of Bretton Woods capital controls on global and regional economic activity. A three-region DSGE capital flows accounting framework consisting of the U.S., Western Europe, and the Rest of the World (ROW) is developed to quantify capital controls and evaluate their impact on the world economy. We conduct counterfactual analyses that eliminate Bretton Woods’ capital controls and find these controls substantially reduced global capital flows, had large negative welfare effects on the U.S., raised welfare substantially in the ROW, and ...

Foreign Exchange Reserves as a Tool for Capital Account Management
Many recent theoretical papers have argued that countries can insulate themselves from volatile world capital flows by using a variable tax on foreign capital as an instrument of monetary policy. But at the same time many empirical papers have argued that only rarely do we observe these cyclical capital taxes used in practice. In this paper we construct a small open economy model where the central bank can engage in sterilized foreign exchange intervention. When private agents can freely buy and sell foreign bonds, sterilized foreign exchange intervention has no effect. But we analytically ...

Capital controls: a normative analysis
Countries' concerns about the value of their currency have been studied and documented extensively in the literature. Capital controls can be?and often are?used as a tool to manage exchange rate fluctuations. This paper investigates whether countries can benefit from using such a tool. We develop a welfare-based analysis of whether (or, in fact, how) countries should tax international borrowing. Our results suggest that restricting international capital flows through the use of these taxes can be beneficial for individual countries, although it would limit cross-border pooling of risk. The ...

Interview: Stephanie Schmitt-Grohé
Stephanie Schmitt-Grohé is probably one of the few top-level economics researchers without a college degree. A native of Germany, she enrolled to study economics at the University of Münster. After completing two years of her studies, she was offered a Fulbright scholarship to study in the United States. She left temporarily — or so she thought.

Optimal Capital Account Liberalization in China
China maintains tight controls over its capital account. Its current policy regime also features financial repression, under which banks are required to extend funds to state-owned enterprises (SOEs) at favorable terms, despite their lower productivity than private firms on average. We incorporate these features into a general equilibrium model. Our model illustrates a tradeoff between aggregate productivity and inter-temporal allocative efficiency from capital account liberalization under financial repression. As a result, along a transition path with a declining SOE share, ...

Insider Networks
Modern-day financial systems are highly complex, with billions of exchanges in information, assets, and funds between individuals and institutions. Though daunting to operationalize, regulating these transmissions may be desirable in some instances. For example, securities regulators aim to protect investors by tracking and punishing insider trading. Recent evidence shows that insiders have formed sophisticated networksthat enable them to pursue activities outside the purview of regulatory oversight. In understanding the cat-and-mouse game between regulators and insiders, a key consideration ...

The Impact of Bretton Woods International Capital Controls on the Global Economy and the Value of Geopolitical Stability: A General Equilibrium Analysis
This paper quantifies the positive and normative impacts of Bretton Woods capital controls on global economic activity. It applies a three-region DSGE model consisting of the U.S., Western Europe, and the Rest of the World (ROW) to measure de facto capital controls and analyze their effects. Counterfactual analyses show Bretton Woods controls significantly prevented ROW capital from flowing to the U.S., had large negative welfare effects on the U.S., raised welfare in the ROW, and increased global output. Why did the U.S. support controls, given lower welfare? By keeping capital in the ROW, ...
