Disasters Everywhere: The Costs of Business Cycles Reconsidered
Business cycles are costlier and stabilization policies more beneficial than widely thought. This paper shows that all business cycles are asymmetric and resemble mini “disasters”. By this we mean that growth is pervasively fat-tailed and non-Gaussian. Using long-run historical data, we show empirically that this is true for all advanced economies since 1870. Focusing on the peacetime sample, we develop a tractable local projection framework to estimate consumption growth paths for normal and financial-crisis recessions. Using random coefficient local projections we get an easy and ...

Supervisory Stress Testing For CCPs : A Macro-Prudential, Two-Tier Approach
Stress testing has become an increasingly important mechanism to support a variety of financial stability objectives. Stress tests can be used to test the individual resilience of a single entity or to assess the system-wide vulnerabilities of a network. This article examines the role of supervisory stress testing of central counterparties (CCPs), which has emerged in recent years. A key message is that crucial differences in CCPs? role, risk profile and financial structure, when compared to banks, are likely to require significant adaptation in the design of supervisory stress tests (SSTs). ...

Capital Buffers in a Quantitative Model of Banking Industry Dynamics
We develop a model of banking industry dynamics to study the quantitative impact of regulatory policies on bank risk taking and market structure as well as the feedback effect of market structure on the efficacy of policy. Since our model is matched to U.S. data, we propose a market structure where big banks with market power interact with small, competitive fringe banks. Banks face idiosyncratic funding shocks in addition to aggregate shocks which affect the fraction of performing loans in their portfolio. A nontrivial bank size distribution arises out of endogenous entry and exit, as well ...

The macroprudential implications of the 1990s Japanese financial crisis: remarks at the 5th Annual Macroprudential Conference, Eltville, Germany, June 21, 2019
The Japanese financial crisis of the late 1990s had significant implications for both the Japanese and global economies. Effective use of macroprudential tools ? that is, banking regulations aimed at mitigating financial-system risk ? could have lessened the crisis in Japan. Unfortunately, it wasn't until the financial crisis of 2008 that countries began to work on improving macroprudential policies. Bank stress tests and the use of a countercyclical capital buffer (or CCyB) are two macroprudential tools that emerged from the financial crisis which could have reduced the severity of the ...

Monetary policy, financial conditions, and financial stability
We review a growing literature that incorporates endogenous risk premiums and risk taking in the conduct of monetary policy. Accommodative policy can create an intertemporal trade-off between improving current financial conditions and increasing future financial vulnerabilities. In the United States, structural and cyclical macroprudential tools to reduce vulnerabilities at banks are being implemented, but they may not be sufficient because activities can migrate and there are limited tools for nonbank intermediaries and for borrowers. While monetary policy itself can influence ...

A Quantitative Analysis of Countercyclical Capital Buffers
What are the quantitative macroeconomic effects of the countercyclical capital buffer (CCyB)? I study this question in a nonlinear DSGE model with occasional financial crises, which is calibrated and combined with US data to estimate sequences of structural shocks. Raising capital buffers during leverage expansions can reduce the frequency of crises by more than half. A quantitative application to the 2007-08 financial crisis shows that the CCyB in the 2.5% range (as in the Federal Reserve's current framework) could have greatly mitigated the financial panic of 2008, for a cumulative gain of ...

Coordinating monetary and macroprudential policies
The financial crisis has prompted macroeconomists to think of new policy instruments that could help ensure financial stability. Policymakers are interested in understanding how these should be set in conjunction with monetary policy. We contribute to this debate by analyzing how monetary and macroprudential policy should be conducted to reduce the costs of macroeconomic fluctuations. We do so in a model in which such costs are driven by nominal rigidities and credit constraints. We find that, if faced with cost-push shocks, policy authorities should cooperate and commit to a given course of ...

Mapping Heat in the U.S. Financial System
We provide a framework for assessing the build-up of vulnerabilities in the U.S. financial system. We collect forty-four indicators of financial and balance-sheet conditions, cutting across measures of valuation pressures, nonfinancial borrowing, and financial-sector health. We place the data in economic categories, track their evolution, and develop an algorithmic approach to monitoring vulnerabilities that can complement the more judgmental approach of most official-sector organizations. Our approach picks up rising imbalances in the U.S. financial system through the mid-2000s, presaging ...

A Quantitative Analysis of Countercyclical Capital Buffers
What are the quantitative effects of countercyclical capital buffers (CCyB)? I study this question in the context of a nonlinear DSGE model with a financial sector that is subject to occasional panics. A calibrated version of the model is combined with US data to estimate sequences of structural shocks, allowing me to study policy counterfactuals. First, I show that raising capital buffers during leverage expansions can reduce the frequency of crises by more than half. Second, I show that lowering capital buffers during a panic can moderate the intensity of the resulting crisis. A ...
