The legal regulations require the minimum wage in Germany to be adjusted biennially which gives rise to a policy discontinuity. From the perspective of rational expectations models, such policy features render standard local approximation techniques infeasible. The paper presents a stylised...

We simulate the fiscal stimulus packages set up by the German government to allevi-ate the costs of the COVID-19 pandemic in a dynamic New Keynesian multi-sectorgeneral equilibrium model. We find that, cumulated over 2020-2022, output lossesrelative to steady state can be reduced by more than 4...

This policy report studies the effects of a sudden stop of natural gas imports from Russia on the German economy. The analysis focuses on the supply-side effects that arise when a gas shortage affects production in the gas-intensive manufacturing sectors, with a corresponding production...

We study whether a central bank should deviate from its objective of price stability to promote financial stability. We tackle this question within a textbook New Keynesian model augmented with capital accumulation and microfounded endogenous financial crises. We compare several interest rate...

Arguing that in the real world relatively optimistic inexperienced investors are prey for relatively pessimistic veteran traders, we formalize this intuitive conjecture as a proven proposition in a simple model. This agreement to disagree leads to a perpetual bubble, in which more experienced,...

We study price dispersion and venue choice in the interdealer market for German sovereign bonds, where an exchange and over-the-counter segments coexist. We show that 85% of OTC traded prices are favorable with respect to exchange quotes, indicating the prevalence of an OTC discount. This...

We study the liquidity allocation among European banks around the Lehman insolvency using a novel dataset of all interbank loans settled via the Eurosystem’s payment system TARGET2. Following the Lehman insolvency, lenders in the overnight segment become sensitive to counterparty...

Does banks' zombie lending induced by unconventional monetary policy also allow zombie firms to leverage their trade credit borrowing? We first provide evidence suggesting that - even in Germany - particularly weak banks used the European Central Bank's very long-term refinancing operations...

The reuse of collateral can support the efficient allocation of assets in the financial system. Exploiting a novel dataset, we quantify banks’ collateral reuse at the security level. We show that banks substantially increase their reuse of collateral in response to scarcity induced by central...
