This paper examines the interactions of macroprudential and monetary policies. We find, using a range of macroeconomic models used at the European Central Bank, that in the long run, a 1% bank capital requirement increase has a small impact on GDP. In the short run, GDP declines by 0.15-0.35%....

We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence can give rise to persistent liquidity trap episodes. Unlike in the case of fundamental-driven liquidity traps, there is no straightforward recipe for mitigating the welfare costs...

This paper proposes a tractable New Keynesian (NK) economy with endogenous adjustment in product quality that nests the canonical framework. Endogenous quality choice reduces the slope of the traditional NK Phillips curve and ampliffes the economy's response to productivity shocks. This leads to...

We study how the use of judgement or add-factorsʺ in macroeconomic forecasting may disturb the set of equilibrium outcomes when agents learn using recursive methods. We isolate conditions under which new phenomena, which we call exuberance equilibria, can exist in standard macroeconomic...

Swift changes in investors' sentiment, such as the one triggered by COVID-19 global outbreak in March 2020, lead to financial tensions and asset price volatility. We study the interactions of behavioral and financial frictions in an environment with endoge- nous risk-taking and capital...

I study macro-prudential policy intervention in economies with secularly low interest rates. Intervention boosts risk-free real interest rates unintentionally, simply as a by-product of containing systemic risk in financial markets. Thus, intervention also boosts the natural rate of return in...
