Banks, Capital Flows and Financial Crises
This paper proposes a macroeconomic model with financial intermediaries (banks), in which banks face occasionally binding leverage constraints and may endogenously affect the strength of their balance sheets by issuing new equity. The model can account for occasional financial crises as a result of the nonlinearity induced by the constraint. Banks' precautionary equity issuance makes financial crises infrequent events occurring along with "regular" business cycle fluctuations. We show that an episode of capital infl ows and rapid credit expansion, triggered by low country interest rates, ...

Good news is bad news: leverage cycles and sudden stops
We show that a model with imperfectly forecastable changes in future productivity and an occasionally binding collateral constraint can match a set of stylized facts about ?sudden stop? events. ?Good? news about future productivity raises leverage during times of expansion, increasing the probability that the constraint binds, and a sudden stop occurs, in future periods. The economy exhibits a boom period in the run-up to the sudden stop, with output, consumption, and investment all above trend, consistent with the data. During the sudden stop, the nonlinear effects of the constraint induce ...

International Reserves, Credit Constraints, and Systemic Sudden Stops
Why do emerging market economies simultaneously hold very high levels of international reserves and foreign liabilities? Moreover, why, even with such huge amounts of international reserves, did countries barely use them during the Global Financial Crisis? I argue that including international reserves as an implicit collateral for external borrowing in a small open economy model subject to exogenous financial shocks can explain both of these puzzling facts. I find that the model can obtain ratios of international reserves and net foreign liabilities to GDP similar to those of Latin American ...

Managing Capital Flows in the Presence of External Risks
We introduce external risks, in the form of shocks to the level and volatility of world interest rates, into a small open economy model subject to the risk of sudden stops?large recessions together with abrupt reversals in capital inflows| and characterize optimal macroprudential policy in response to these shocks. In the model, collateral constraints create a pecuniary externality that leads to "overborrowing" and sudden stops that arise when the constraints bind. The typical sudden stop generated by the model replicates existing empirical evidence for emerging market economies: Low and ...

Inequality and Asset Prices during Sudden Stops
This paper studies the cross-sectional dimension of Fisher’s debt-deflation mechanism that triggers Sudden Stop crises. Analyzing microdata from Mexico, we show that this dimension has macroeconomic implications that operate via opposing effects. We propose a small open economy, asset-pricing model with heterogeneous-agents and aggregate risk to measure the effects of inequality during crises. In contrast to a representative-agent model, heterogeneity generates persistent current account reversals with smaller drops in asset prices and larger drops in consumption driven by the leveraged ...

The Role of U.S. Monetary Policy in Global Banking Crises
We examine the role of U.S. monetary policy in global financial stability by using a cross-country database spanning the period from 1870-2010 across 69 countries. U.S. monetary policy tightening increases the probability of banking crises for those countries with direct linkages to the U.S., either in the form of trade links or significant share of USD-denominated liabilities. Conversely, if a country is integrated globally, rather than having a direct exposure, the effect is ambiguous. One possible channel we identify is capital flows: If the correction in capital flows is disorderly (e.g., ...

Credit spreads, financial crises, and macroprudential policy
Credit spreads display occasional spikes and are more strongly countercyclical in times of financial stress. Financial crises are extreme cases of this nonlinear behavior, featuring skyrocketing credit spreads, sharp losses in bank equity, and deep recessions. We develop a macroeconomic model with a banking sector in which banks? leverage constraints are occasionally binding and equity issuance is endogenous. The model captures the nonlinearities in the data and produces quantitatively realistic crises. Precautionary equity issuance makes crises infrequent but does not prevent them ...

Financial Crises and the Desirability of Macroprudential Policy
The global financial crisis has put financial stability risks?and the potential role of macroprudential policies in addressing them?at the forefront of policy debates. The challenge for macroeconomists is to develop new models that are consistent with the data while being able to capture the highly nonlinear nature of crisis episodes. In this post, we evaluate the impact of a macroprudential policy that has the government tilt incentives for banks to encourage them to build up their equity positions. The government has a role since individual banks do not internalize the systemic benefit of ...

Large Capital Inflows, Sectoral Allocation, and Economic Performance
This paper describes the stylized facts characterizing periods of exceptionally large capital inflows in a sample of 70 middle- and high-income countries over the last 35 years. We identify 155 episodes of large capital inflows and find that these events are typically accompanied by an economic boom and followed by a slump. Moreover, during episodes of large capital inflows capital and labor shift out of the manufacturing sector, especially if the inflows begin during a period of low international interest rates. However, accumulating reserves during the period in which capital inflows are ...

Modeling the Global Effects of the COVID-19 Sudden Stop in Capital Flows
The COVID-19 outbreak has triggered unusually fast outflows of dollar funding from emerging market economies (EMEs). These outflows are known as “sudden stop” episodes, and they are typically followed by economic contractions. In this post, we assess the macroeconomic effects of the COVID-induced sudden stop of capital flows to EMEs, using our open-economy DSGE model. Unlike existing frameworks, such as the Federal Reserve Board’s SIGMA model, our model features both domestic and international financial constraints, making it well-suited to capture the effects of an outflow of ...
