In Zeiten von Digitalisierung, Niedrigzinsen und Kryptogeld stehen viele ökonomische Prozesse und insbesondere die Finanzintermediation auf dem Prüfstand. Im vorliegenden Beitrag wird dabei die Rolle der Geldpolitik kritisch mit Blick auf ihre „Ultraexpansivität“ reflektiert und...

I analyse the dynamics of a New Keynesian DSGE model where the financing of investments is affected by a moral hazard problem. I solve for jointly Ramsey-optimal monetary and macroprudential policies. I find that when a financial friction is present in addition to the standard nominal friction,...

This study examines the Twitter policies and use of European central banks. Almost every European central bank maintains an institutional Twitter account, but tweeting activity, tweet content and usage restrictions on Twitter use by individual staff members vary considerably. We further consider...

The case for central bank independence is built on an intellectual two-step. Step one argues there is a problem of inflation prone government. Step two argues independence is the solution to that problem. This paper challenges that case and shows it is based on false politics and economics. The...

Die Ankündigung der Libra Association, mit Libra eine private globale Währung zu emittieren, hat eine heftige Debatte über die damit verbundenen Chancen und Risiken ausgelöst. Befürworter erwarten, dass Libra das Geldsystem von seinen „staatlichen Fesseln“ befreien und den...

We investigate the transmission of changes in bank capital requirements and supranational monetary policy, and their interaction effect, on euro area bank lending and lending rates. Our results show that - for weakly capitalized banks - increases in capital requirements are in the short-run...

In this paper, we bring new evidence using Uganda's supervisory credit register, with microdata on loan applications, volumes and rates, coupled with unanticipated variation in...

We show that countercyclical liquidity policy smooths credit supply cycles, with stronger crisis effects. For identification, we exploit the Brazilian supervisory credit register and liquidity policy changes on reserve requirements, that affected banks differentially and have a monetary and...

Monetary policy transmission may be impaired if banks rebalance their portfolios towards securities to e.g. risk-shift or hoard liquidity. We identify the bank lending and risk-taking channels by exploiting – Italian’s unique – credit and security registers. In crisis times, with higher...
