Using a new administrative dataset, we provide fresh micro-level evidence on firms' returns to scale (RTS). We employ a new administrative database, iBACH, which contains extensive high-quality annual balance sheet, financial, and demographic information on more than two million non-financial...

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...

Central bank announcements move financial markets. The response of inflation and growth expectations, on the other hand, is often small or even counterintuitive. Based on tick-by-tick futures prices on bonds and stock prices, I confirm these seemingly puzzling results for the euro area and...

In a parsimonious regime switching model, expected consumption growth varies over time. Adding in ation as a conditioning variable, we uncover two states in which expected consumption growth is low, one with high and one with negative expected in ation. Embedded in a general equilibrium asset...

We analyse the cross-country dimension of financial cycles by studying cyclical co-movements in credit, house prices, equity prices and interest rates across the G7 economies. We use wavelet-based statistics to assess at which frequencies cyclical fluctuations and their crosscountry co-movements...

According to current regulation, European banks can apply zero risk weights to sovereign exposures in their balance sheet, irrespective of the assigned rating. We show that a zero risk weighting of sovereign bonds has implications by distorting banks' asset allocation decisions. Due to the lower...

In a three-region New Keynesian life-cycle model calibrated to Germany, the Euro area (without Germany) and the rest of the world, we analyze the impact of population ageing on net foreign asset and current account developments. Using unsynchronized demographic trends by taking those of Germany...

The current paper broadens the understanding for the role of uncertainty in the context of a macroeconomic environment. It focuses on the implications of uncertainty shocks on indicators that tend to precede financial crises. In an empirical analysis we show for a set of four euro area countries...

This paper proposes a quantitative multi-sector DSGE model with bank failure and firm default to study the interactions between bank regulation and climate policy. Households value the liquidity of deposits, which are protected by deposit insurance. Banks collect deposits and issue equity to...
