Cost and profit efficiency (CE and PE) are key to evaluate bank performance. But efficiency improvements may imply deteriorating profitability and excessive risk-taking. The dynamic reactions of performance in response to efficiency changes remain unclear on both theoretical and empirical...

The economic policy response to COVID-19 lockdowns included a variety of measures. Their effects on non-financial firms, however, remain unclear. To shed light on the effect of transfers, we investigate the effect of German emergency aid transfers (November-December aid), a program designed for...

In West Germany, the average size of establishments declined during the 1990s and started to increase again in the late 2000s, while the employer size wage premium followed the opposite trajectory. In this paper, we show that these two developments are interrelated. More precisely, our results...

This paper suggests a quantifiable multi-sector-multi-country economic model of goods and services production and consumption. It calibrates overall (variable and fixed) costs to market-specific sales by sector and decomposes these costs into observable and unobservable components. In an...

We investigate whether banks actively manage their exposure to interest rate risk in the short run. Using bank-level data of German banks for the period 2011Q4- 2017Q2, we find evidence that banks actively manage their interest rate risk exposure in their banking books: They take account of...

This paper deals with stress tests for credit risk and shows how exploiting the discretion when setting up and implementing a model can drive the results of a quantitative stress test for default probabilities. For this purpose, we employ several variations of a CreditPortfolioView-style model...

Broker-dealer leverage has recently proven to be strongly procyclical, exhibiting impressive explanatory power for a large cross-section of asset returns in the US. In this paper we add empirical evidence to this finding, showing that European and German broker-dealers actively manage their...

This paper presents a framework for estimating losses in the residential real estate mortgage portfolios of German banks. We develop an EL model where LGD estimates are based on current collateral values and PD dynamics are estimated using a structural PVAR approach. We confirm empirically that...

For the largest 55 German banks, we detect the presence of countercyclical yield seeking in the form of acquisition of high-yielding periphery bonds in the period from Q1 2008 to Q2 2011. This investment strategy is pursued by banks not subject to a bailout, banks characterised by high...
