This paper seeks to inform about a feature of monetary policy that is largely overlooked, yet occupies a central role in modern monetary and financial systems, namely central bank collateral frameworks. Their importance can be understood by the observation that the money at the core of these...

We document the mechanism through which the risk of fire sales in the sovereign bond market contributed to the effectiveness of two major central bank interventions designed to restore financial stability during the European sovereign debt crisis. As a lender of last resort via the long-term...

Do macroprudential regulations on residential lending influence commercial lending behavior too? To answer this question, we identify the compositional changes in banks' supply of credit using the variation in their holdings of residential mortgages on which extra capital requirements were...

What is the impact of policy interventions on the systemic risk of banks? To answer this question, we analyze a comprehensive sample that combines an original set of bank-specific bailout events with balance sheets of key affected and non-affected European banks between 2005 and 2014. We find a...

Using an agent-based model (ABM) with fundamentalists and chartists, prone to develop bubbles and crashes, we demonstrate the usefulness of direct market intervention by a policy maker, documenting strong performance in preventing bubbles and drawdowns and augmenting significantly the welfare of...

Sentiment analysis is applied to the Federal Reserve's documents relating to the Federal Open Market Committee (FOMC). A new method of rating the sentiment of texts is developed through the creation of a 100 000 word sentiment dictionary, and is used to estimate the sentiment of the Beige Book...

This paper investigates the impact of central banks when supporting policies aiming at greening the financial system. The July 2021 Monetary Policy Strategy Review of the European Central Bank unexpectedly dedicated a whole workstream to climate change. The announcement had a significant effect...

We study the general problem of information design for a policymaker—a central bank—that communicates its private information (the ``state") to the public. We show that it is optimal for the policymaker to partition the state space into a finite number of ``clusters” and to communicate to...

Central banks are under increased scrutiny because of the rapid growth in, and composition of, their balance sheets. Therefore, understanding the processes that shape these balance sheets and their consequences is crucial. We contribute by studying an extensive dataset of banks' liquidity uptake...

We present a self-consistent model for explosive financial bubbles, which combines a mean-reverting volatility process and a stochastic conditional return which reflects nonlinear positive feedbacks and continuous updates of the investors' beliefs and sentiments. The conditional expected returns...
