What risks do asset price bubbles pose for the economy? This paper studies bubbles in housing and equity markets in 17 countries over the past 140 years. History shows that not all bubbles are alike. Some have enormous costs for the economy, while others blow over. We demonstrate that what makes...

I find that the Eurosystem can stimulate the economy beyond the policy rate by increasing the size of its balance sheet or the monetary base, that is so-called quantitative easing. The transmission mechanism turns out to be different compared to traditional interest rate innovations: (i) whilst...

Shocks to bank lending, risk-taking and securitization activities that are orthogonal to real economy and monetary policy innovations account for more than 30 percent of U.S. output variation. The dynamic effects, however, depend on the type of shock. Expansionary securitization shocks lead to a...

We estimate the effects of exogenous innovations to the balance sheet of the ECB since the start of the financial crisis within a structural VAR framework. An expansionary balance sheet shock stimulates bank lending, stabilizes financial markets, and has a positive impact on economic activity...

We develop a stylized DSGE model in which banks face capital regulation and their loan portfolios are subject to non-diversifiable losses due to aggregate shocks. The framework is used to explore the importance of the interaction between macroeconomic conditions, credit default and bank...

This paper presents a micro data approach to the identification of credit crunches. Using a survey among German firms which regularly queries the firms' assessment of the current willingness of banks to extend credit we estimate the probability of a restrictive credit supply policy by time...

This paper seeks to understand the interplay between banks, bank regulation, sovereign default risk and central bank guarantees in a monetary union. I assume that banks can use sovereign bonds for repurchase agreements with a common central bank, and that their sovereign partially backs up any...

We use an original monthly dataset of 131 individual euro area banks to examine the effectiveness and transmission mechanism of the Eurosystem’s credit support policies since the start of the crisis. First, we show that these policies have indeed been succesful in stimulating the credit flow...

We study the contribution of loans, granted to different borrower groups, to economic activity in the USA over the period 1971q1-2018q4. Significant economic recessions occurred along the period considered, we center our discussion around the recent Global Financial Crisis. Results are delivered...

Central bank digital currencies (CBDCs) are receiving more attention than ever before. Yet the motivations for issuance vary across countries, as do the policy approaches and technical designs. We investigate the economic and institutional drivers of CBDC development and take stock of design...
