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 are typically followed by economic contractions.
The Impact of Foreign Slowdown on the U.S. Economy: An Open Economy DSGE Perspective
Over the course of 2018, economic activity in major advanced foreign economies and emerging markets—including the Euro area and China—decelerated noticeably. In parallel, foreign growth projections for 2019 and 2020 were revised down, signaling potentially large headwinds for the U.S economy over the medium term. In this article, we use a multi-country simulation model to quantify economic spillovers to the United States from a slowdown originating in the Euro area. Next, we compare these results with spillovers from a slowdown originating in China. We find that spillovers to the U.S. ...
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, ...
The Financial (In)Stability Real Interest Rate, R**
We introduce the concept of a financial stability real interest rate using a macroeconomic banking model with an occasionally binding financing constraint, as in Gertler and Kiyotaki (2010). The financial stability interest rate, r**, is the threshold interest rate that triggers the constraint being binding. Increasing imbalances in the financial sector, measured by an increase in leverage, are accompanied by a lower threshold that could trigger financial instability events. We also construct a theoretical implied financial conditions index and show how it is related to the gap between the ...
U.S. Monetary Policy Spillovers to Emerging Markets: Both Shocks and Vulnerabilities Matter
Using a macroeconomic model, we explore how sources of shocks and vulnerabilities matter for the transmission of U.S. monetary changes to emerging market economies (EMEs). We utilize a calibrated two-country New Keynesian model with financial frictions, partly-dollarized balance sheets, and imperfectly anchored inflation expectations. Contrary to other recent studies that also emphasize the sources of shocks, our approach allows the quantification of effects on real macroeconomic variables as well, in addition to financial spillovers. Moreover, we model the most relevant vulnerabilities ...
Good News, Leverage, and Sudden Stops
One of the major debates in open economy macroeconomics is the extent to which capital inflows are beneficial for growth. In principle, these flows allow countries to increase their consumption and investment spending beyond their income by enabling them to tap into foreign saving. Periods of such borrowing, however, are associated with large trade deficits, external debt accumulation, and, in some cases, overheating when these economies operate beyond their potential output level for an extended period of time. The relevant question in this context is whether the rate at which a country is ...
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 ...
How Effective are Macroprudential Policies? An Empirical Investigation
In recent years, policymakers have generally relied on macroprudential policies to address financial stability concerns. However, our understanding of these policies and their efficacy is limited. In this paper, we construct a novel index of domestic macroprudential policies in 57 advanced and emerging economies covering the period from 2000:Q1 to 2013:Q4, with tightenings and easings recorded separately. The effectiveness of these policies in curbing bank credit growth and house price inflation is then assessed using a dynamic panel data model. The main findings of the paper are: (1) ...

International Evidence on the Use and Effectiveness of Macroprudential Policies
In recent years, policymakers in advanced and emerging economies have employed a variety of macroprudential policy tools?targeted rules or requirements that enhance the stability of the financial system as a whole by addressing the interconnectedness of individual financial institutions and their common exposure to economic risk factors. To examine the foreign experience with these tools, we constructed a novel macroprudential policy (MAPP) index. This index allows us to quantify the effects of these policies on bank credit and house prices, two variables that are often the target of ...
