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. ...

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 ...

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 ...

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, ...

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.

A Way With Words: The Economics of the Fed’s Press Conference
When central bankers speak, traders, journalists, and politicians listen with bated breath. The marked asset price reaction to Chairman Bernanke’s June press conference confirms the importance of his comments in the marketplace.

Are Asset Managers Vulnerable to Fire Sales?
According to conventional wisdom, an open-ended investment fund that has a floating net asset value (NAV) and no leverage will never experience a run and hence never have to fire-sell assets. In that view, a decline in the value of the fund’s assets will just lead to a commensurate and automatic decline in the fund’s equity—end of story. In this post, we argue that the conventional wisdom is incomplete and then explore some of the systemic risk consequences of investment funds’ vulnerabilities to fire-sale spillovers.

Financial vulnerability and monetary policy
We present a microfounded New Keynesian model that features financial vulnerabilities. Financial intermediaries' occasionally binding value-at-risk constraints give rise to variation in the pricing of risk that generates time-varying risk in the conditional mean and volatility of the output gap. The conditional mean and volatility are negatively related: during times of easy financial conditions, growth tends to be high, and risk tends to be low. Monetary policy affects output directly through the investment-savings curve, and indirectly through the pricing of risk that relates to the ...

On Fire-Sale Externalities, TARP Was Close to Optimal
Imagine that many large and levered banks suffer heavy losses and must quickly sell assets to reduce their leverage. We expect the market price of the assets sold to decline, at least temporarily. As a result, any other financial institutions that happen to hold the same assets will experience balance sheet losses through no fault of their own —a negative fire-sale externality. In this post, we show that the vulnerability to fire-sale externalities was high during the crisis and that the capital injections of the government’s Troubled Asset Relief Program (TARP) helped reduce it ...
