Der Ausblick auf die internationale Konjunktur 2023 ist verschattet: Die Energieversorgung Europas ist ungewiss, die Leitzinsen steigen weiter, der Pandemieausbruch in China führt zu Produktionsausfällen. Belastungen für die deutsche Wirtschaft kommen von hohen Energiepreisen und einem verschlechterten Finanzierungsumfeld. Bislang ist die Konjunktur robust, die Produktion hat bis in den Herbst hinein expandiert. Ab dem Frühjahr wird sie gestützt durch die weitere Entspannung der Lieferketten und eine Belebung der Weltwirtschaft. Das BIP dürfte 2022 in den ersten drei Quartalen um 1,8% zugenommen haben, den Winter über leicht sinken und 2023 insgesamt stagnieren (Ostdeutschland: 1,8% und 0,2%). Die Inflation geht nach 7,8% im Jahr 2022 auf 6,5% im Jahr 2023 zurück.

Banks play a special role in the financial system. According to classical banking theory, they help reduce informational asymmetries and serve as liquidity providers. Banks can, at least partially, lower transaction costs that result from information frictions between investors and firms and thereby alleviate firms’ funding constraints (Diamond, 1984). Moreover, banks create liquidity on their balance sheets by financing comparably illiquid assets with relatively liquid liabilities (Diamond and Dybvig, 1983). Integrating credit and liquidity provision functions, banks have been the object of numerous studies on financial intermediation. A particular focus in recent years has been on banks’ behavior as well as on the con- sequences of their actions for the real economy when hit by adverse shocks. Following the global financial crisis, financial shocks that originate from within the financial sec- tor have received wide attention (Cingano et al., 2016; Chodorow-Reich, 2014; Khwaja and Mian, 2008; Paravisini, 2008; Paravisini et al., 2015; Schnabl, 2012). However, banks are also subject to numerous non-financial shocks, which are the focus of this thesis.

We use a new database on European real estate purchase and rental prices – the IWH European Real Estate Index – to document the relationship between staggered COVID-19 dynamics and real estate prices in 14 EU countries between January 2020 and December 2021. For most countries, we find no statistically significant response of monthly purchase and rental prices due to an increase of regional COVID-19 cases. For the UK we find that more COVID-19 cases depressed both purchase and rental prices significantly, but the economic magnitude of effects was mild during this sample period. In contrast, rents in Italy increased in response to hiking COVID-19 cases, illustrating the importance to consider heterogeneous crisis patterns across the EU when designing policies. Overall, COVID-19 dynamics did not affect real estate values significantly during the pandemic, thereby mitigating potential financial stability concerns via a mortgage lending channel at the time.

Im Spätsommer 2022 ist die Weltwirtschaft im Abschwung. Die US-Notenbank und weitere Zentralbanken haben aufgrund der hohen Inflation mit der Straffung ihrer Geldpolitik begonnen, die chinesische Konjunktur schwächelt, und Europa kämpft mit einer Energiekrise. Die deutsche Wirtschaft steht aufgrund der stark steigenden Energiekosten vor einer Rezession. Das deutsche Bruttoinlandsprodukt wird im Jahr 2022 um 1,1% zunehmen und im Jahr 2023 um 1,4% sinken. Die Verbraucherpreise steigen im Jahr 2022 um 7,9% und im Jahr 2023 um 9,5%.

This paper investigates whether managers’ personal connections help corporate productivity to recover after a negative economic shock. Leveraging the heterogeneity in the severity of the financial crisis across different sectors, the paper reports that (i) the financial crisis had a negative effect on within-firm productivity, (ii) the effect was long-lasting and persistent, supporting a productivity-hysteresis hypothesis, and (iii) managers’ personal connections allowed corporations to recover from this productivity slowdown. Among the possible mechanisms, we show that connected managers operating in affected sectors foster productivity recovery through higher input cost efficiency and better access to the credit market, as well as more efficient use of labour and capital.
