The frequencies at which prices and wages are adjusted, interpreted as price and wage flexibility, are key elements in workhorse models used for policy analysis. Yet, there is little evidence regarding the relationship between these two sources of nominal rigidities. Using two large and highly...

Using a DSGE framework, we discuss the optimal design of monetary policy for an economy where both retail banks and shadow banks serve as financial intermediaries. We get the following results. During crises times, a standard Taylor rule fails to reach sufficient stimulus. Direct asset purchases...

This paper reviews the theoretical literature at the intersection of macroeconomics and finance to draw lessons on the connection between vulnerabilities in the financial system and the macroeconomy, and on how monetary policy affects that connection. This literature finds that financial...

This study tests for the state-dependent response of monetary policy to increases in overall financial stress and financial sector-specific stress across a panel of advanced and emerging economy central banks. We use a factor-augmented dynamic panel threshold regression model with (estimated)...

We introduce time-varying systemic risk (à la He and Krishnamurthy, 2014) in an otherwise standard New-Keynesian model to study whether simple leaning-against-the-wind interest rate rules can reduce systemic risk and improve welfare. We find that while financial sector leverage contains...

We re-examine the relationship between monetary policy and financial stability in a setting that allows for nonlinear, time-varying relationships between monetary policy, financial stability, and macroeconomic outcomes. Using novel machine-learning techniques, we estimate a flexible "nonlinear...

This paper investigates the identification, the determinacy and the stability of ad hoc, "quasi-optimal" and optimal policy rules augmented with financial stability indicators (such as asset prices deviations from their fundamental values) and minimizing the volatility of the policy interest...

This paper provides an empirical assessment of the power of forward guidance at different horizons, shedding new light on the strength of the "forward guidance puzzle". Our identification strategy allows us to disentangle the change in future interest rates stemming from deviations from the...

This article analyzes the impact of the unconventional monetary policies (UMPs) of four major central banks (the Fed, ECB, BoE and BOJ) on the probability of future market crashes. We exploit the heterogeneity of different UMP actions to disentangle their influence on reducing the ex ante...

The purpose of public policy, expansionary or contractionary, is to encourage the expansion of income, output, and employment. Theory decides the nature and kind of policy, and the underlying mechanics that result in expansion. Keynes (1964) brings money and a monetary production economy to the...
