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.

I show that rising temperatures can detrimentally affect the sovereign creditworthiness of emerging economies. To this end, I collect long-term monthly temperature data of 54 emerging markets. I calculate a country’s temperature deviation from its historical average, which approximates present-day climate change trends. Running regressions from 1994m1 to 2018m12, I find that higher temperature anomalies lower sovereign bond performances (i.e., increase sovereign risk) significantly for countries that are warmer on average and have lower seasonality. The estimated magnitudes suggest that affected countries likely face significant increases in their sovereign borrowing costs if temperatures continue to rise due to climate change. However, results indicate that stronger institutions can make a country more resilient towards temperature shocks, which holds independent of a country’s climate.

Capital inflow surges destabilize the economy through a maturity shortening mechanism. The underlying reason is that firms have incentives to redeem their debt on demand to accommodate the potential liquidity needs of global investors, which makes international borrowing endogenously fragile. Based on a theoretical model and empirical evidence at both the firm and macro levels, our main findings are twofold. First, a significant association exists between surges and shortened corporate debt maturity, especially for firms with foreign bank relationships and higher redeployability. Second, the probability of a crisis following surges with a flattened yield curve is significantly higher than that following surges without one. Our study suggests that debt maturity is the key to understand the financial instability consequences of capital inflow bonanzas.

This study analyzes business cycle characteristics for all 20 major contemporaneous economies bordering the Mediterranean Sea based on annual real gross domestic product series for the period from 1960 to 2019. The region we investigate corresponds to the Mare Internum region of the Imperial Roman Empire during the Nerva-Antonine and early Severan dynasty, i.e., at the time of the maximum extent of the Roman Empire around 100 to 200 CE. The covered area encircles the Mediterranean, including economies now belonging to the European Union as well as acceding countries, Turkey, and the Middle East and North African economies. Using a components-deviation-cycle approach, we assess level trends and relative volatility of output. We also quantify the contribution of various factors to the business cycle variability within a region. We find cyclic commonalities and idiosyncrasies are related to ancient and colonial history and to contemporaneous trade relationships. Caliphate and Ottoman Empire membership as well as colonial rule in the twentieth century and contemporary Muslim share of population are the most promising predictors of business cycle commonalities in the region.

Die deutsche Wirtschaft wird von der krisenhaften Zuspitzung auf den Gasmärkten schwer belastet. Die hochgeschnellten Gaspreise erhöhen die Energiekosten drastisch und gehen mit einem massiven gesamtwirtschaftlichen Kaufkraftentzug einher. Dies dämpft nicht nur die noch unvollständige Erholung von der Coronakrise, sondern drückt die deutsche Wirtschaft in die Rezession. Dabei kommen die Institute für den kommenden Winter zu dem Ergebnis, dass bei normalen Witterungsbedingungen keine Gasmangellage eintritt. Dennoch bleibt die Versorgungslage äußerst angespannt. Vor diesem Hintergrund dürfte die Wirtschaftsleistung im dritten Quartal bereits leicht gesunken sein. Im Winterhalbjahr ist aufgrund der steigenden Kosten für Energie, der nachlassenden Konsumnachfrage und der schwächelnden Weltwirtschaft mit einem deutlichen Rückgang zu rechnen.

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 dissertation is about questions on how German institutions of industrial relations shape plant-level outcomes, and how this influences employer wage differentials. Employer wage differentials point toward imperfect labor markets in which both, employers and employees, benefit from employment rents. It puts the employer at the center of explaining wage differences and how employer characteristics influence these, over which individual employees have only limited control. Arguably, how employers and employees split these rents depend on industrial relations. The German dual model of industrial relations consists of collective bargaining at the industry level and worker co-determination through works councils at the plant level. This dissertation illuminates different aspects of industrial relations and how rent-sharing mechanisms can explain wage inequality in Germany. It does not only focus on how industrial relations shape labor market power and whether labor market power translates into the level and dispersion of employer wage premia. It also contributes to questions that explain differences in plant-level outcomes relating to industrial relations. These include the role of worker co-determination on assortative matching. It is further investigated how works councils affect plant-level reactions during economy-wide shocks. In addition, it offers new causal evidence of rent-sharing mechanisms in Germany. The insights of this dissertation are relevant for policy and economic research alike. It contributes to a better understanding of the role of organized labor in imperfect labor markets and its determinants of employer wage differentials. It approaches the role of worker co-determination from different angles that are important at times of erosion of formal organized labor but gaining interest in worker representation.
