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 ...

A Macroprudential Theory of Foreign Reserve Accumulation
This paper proposes a theory of foreign reserves as macroprudential policy. We study an open economy model of financial crises, in which pecuniary externalities lead to over-borrowing, and show that by accumulating international reserves, the government can achieve the constrained-efficient allocation. The optimal reserve accumulation policy leans against the wind and significantly reduces the exposure to financial crises. The theory is consistent with the joint dynamics of private and official capital flows, both over time and in the cross section, and can quantitatively account for the ...

Credit Supply and the Housing Boom
There is no consensus among economists as to what drove the rise of U.S. house prices and household debt in the period leading up to the recent financial crisis. In this post, we argue that the fundamental factor behind that boom was an increase in the supply of mortgage credit, which was brought about by securitization and shadow banking, along with a surge in capital inflows from abroad. This argument is based on the interpretation of four macroeconomic developments between 2000 and 2006 provided by a general equilibrium model of housing and credit.

Overborrowing, Underborrowing, and Macroprudential Policy
In this paper, we revisit the scope for macroprudential policy in production economies with pecuniary externalities and collateral constraints. We study competitive equilibria and constrained-efficient equilibria and examine the extent to which the gap between the two depends on the production structure and the policy instruments available to the planner. We argue that macroprudential policy is desirable regardless of whether the competitive equilibrium features more or less borrowing than the constrained-efficient equilibrium. In our quantitative analysis, macroprudential taxes on borrowing ...

Five Points About Monetary Policy and Financial Stability (06-04-2016) Sveriges Riksbank Conference on Rethinking the Central Bank’s Mandate, Stockholm, Sweden
Since the 2008 global financial crisis and the Great Recession that followed, economists and policymakers have been evaluating the factors that led to the crisis, assessing what could have been done to prevent, or at least limit, the damage, and considering what can and should be done to reduce the probability and impact of future disruptions to financial stability. That this is a very broad topic can easily be seen by looking at the agendas of this and previous years? conferences organized by the Riksbank. Today I will focus my remarks on the nexus between monetary policy and financial ...

The Anatomy of Financial Vulnerabilities and Crises
We extend the framework used in Aikman, Kiley, Lee, Palumbo, and Warusawitharana (2015) that maps vulnerabilities in the U.S. financial system to a broader set of advanced and emerging economies. Our extension tracks a broader set of vulnerabilities and, therefore, captures signs of different types of crises. The typical anatomy of the evolution of vulnerabilities before and after a financial crisis is as follows. Pressures in asset valuations materialize, and a build-up of imbalances in the external, financial, and nonfinancial sectors follows. A financial crisis is typically followed by a ...

Financial Stability Committees and Basel III Macroprudential Capital Buffers
We evaluate how a country’s governance structure for macroprudential policy affects its implementation of Basel III macroprudential capital buffers. We find that the probabilities of using the countercyclical capital buffer (CCyB) are higher in countries that have financial stability committees (FSCs) with stronger governance mechanisms and fewer agencies, which reduces coordination problems. These higher probabilities are more sensitive to credit growth, consistent with the CCyB being used to mitigate systemic risk. A country’s probability of using the CCyB is even higher when the FSC ...

Evaluating the Information Value for Measures of Systemic Conditions
Timely identification of coincident systemic conditions and forward-looking capacity to anticipate adverse developments are critical for macroprudential policy. Despite clear recognition of these factors in literature, an evaluation methodology and empirical tests for the information value of coincident measures are lacking. This paper provides a twofold contribution to the literature: (i) a general-purpose evaluation framework for assessing information value for measures of systemic conditions, and (ii) an empirical assessment of the information value for several alternative measures of US ...
Working Paper
Prudential Policies and Their Impact on Credit in the United States
We analyze how two types of recently used prudential policies affected the supply of credit in the United States. First, we test whether the U.S. bank stress tests had any impact on the supply of mortgage credit. We find that the first Comprehensive Capital Analysis and Review (CCAR) stress test in 2011 had a negative effect on the share of jumbo mortgage originations and approval rates at stress-tested banks?banks with worse capital positions were impacted more negatively. Second, we analyze the impact of the 2013 Supervisory Guidance on Leveraged Lending and subsequent 2014 FAQ notice, ...
