Monetary policy and financial conditions: a cross-country study
Loose financial conditions forecast high output growth and low output volatility up to six quarters into the future, generating time-varying downside risk to the output gap, which we measure by GDP-at-Risk (GaR). This finding is robust across countries, conditioning variables, and time periods. We study the implications for monetary policy in a reduced-form New Keynesian model with financial intermediaries that are subject to a Value at Risk (VaR) constraint. Optimal monetary policy depends on the magnitude of downside risk to GDP, as it impacts the consumption-savings decision via the Euler ...

What’s Up with Stocks?
“U.S. stocks are racing toward a second consecutive quarter of dramatic gains, continuing a historic stock-market recovery that few predicted in the depths of the March downturn,” said a September Wall Street Journal article. “The stock market is detached from economic reality. A reckoning is coming,” said the Washington Post. What is going on? In this post, I look not at what stocks have actually done or will do, but at what investors expected should have happened, and what they expect will happen going forward. It turns out that, at least by the particular measure of expectations I ...

Fire-sale spillovers and systemic risk
We reveal and track over time the factors making the financial system vulnerable to fire sales by constructing an index of aggregate vulnerability. The index starts increasing in 2004, before any other major systemic risk measure, more than doubling by 2008. The fire-sale-specific factors of delevering speed and concentration of illiquid assets account for the majority of this increase. Individual banks? contributions to aggregate vulnerability are an excellent five-year-ahead predictor of SRISK, one of the most prominent systemic risk measures. Had our estimates been available at the time, ...

The equity risk premium: a review of models
We estimate the equity risk premium (ERP) by combining information from twenty models. The ERP in 2012 and 2013 reached heightened levels?of around 12 percent?not seen since the 1970s. We conclude that the high ERP was caused by unusually low Treasury yields.

Assessing Contagion Risk in a Financial Network
Since the 2008 financial crisis, there has been an explosion of research trying to understand and quantify the default spillovers that can arise through counterparty risk. This first of two posts delves into the analysis of financial network contagion through this spillover channel. The authors introduce a framework, originally developed by Eisenberg and Noe, that is useful for thinking about default cascades.

How to escape a liquidity trap with interest rate rules
I study how central banks should communicate monetary policy in liquidity trap scenarios in which the zero lower bound on nominal interest rates is binding. Using a standard New Keynesian model, I argue that the key to anchoring expectations and preventing self-fulfilling deflationary spirals is to promise to keep nominal interest rates pegged at zero for a length of time that depends on the state of the economy. I derive necessary and sufficient conditions for this type of state-contingent forward guidance to implement the welfare-maximizing equilibrium as a globally determinate (that is, ...

Ten Years after the Crisis, Is the Banking System Safer?
In the wake of the 2007-09 financial crisis, a wide range of new regulations have been introduced to improve the stability of the banking system. But has the banking system become safer since the crisis? In this post, we provide a new perspective on this question by employing four analytical models, each measuring a different aspect of banking system vulnerability, to evaluate how system stability has evolved over the past decade.

An interest rate rule to uniquely implement the optimal equilibrium in a liquidity trap
We propose a new interest rate rule that implements the optimal equilibrium and eliminates all indeterminacy in a canonical New Keynesian model in which the zero lower bound on nominal interest rates (ZLB) is binding. The rule commits to zero nominal interest rates for a length of time that increases in proportion to how much past inflation has deviated?either upward or downward?from its optimal level. Once outside the ZLB, interest rates follow a standard Taylor rule. Following the Taylor principle outside the ZLB is neither necessary nor sufficient to ensure uniqueness of equilibria. ...

The equity risk premium: a review of models
The authors estimate the equity risk premium (ERP)?the expected return on stocks in excess of the risk-free rate?by combining information from twenty models for the period 1960-2013. They begin their analysis by categorizing the models into five classes: trailing historical mean, dividend discount, cross-sectional estimation, regression analysis using valuation ratios or macroeconomic variables, and surveys. They find that an optimal weighted average of all models places the one-year-ahead ERP in June 2012 at 12.2 percent, close to levels reached in the mid- and late 1970s, when the ERP was ...

Empirical network contagion for U.S. financial institutions
We construct an empirical measure of expected network spillovers that arise through default cascades for the U.S. financial system for the period 2002-16. Compared to existing studies, we include a much larger cross section of U.S. financial firms that comprises all bank holding companies, all broker-dealers, and all insurance companies, and consider their entire empirical balance sheet exposures instead of relying on simulations or on exposures arising just through one specific market (like the fed funds market) or one specific financial instrument (like credit default swaps). We find ...
