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.

The economy is a complex system because market participants do not act independently but adjust their behavior to other agents and to the outcome which emerges from their joint actions (Arthur, 2014). Dependencies among participants can impede policy makers capabilities to influence or steer the course of the economy. Kambhu et al. (2007) argue that to influence developments in financial markets, for instance to prevent crises from spreading, there are only “coarse or indirect options” available for policy makers. Similar to crises which propagate through a complex system, interventions might result in unintended side effects which can also disseminate through the system. Thus, in a complex system, unintended consequences of policy efforts may well be the rule. Policy makers try to ward off or mitigate negative consequences for the economy and society during periods of crisis. For instance, during the Covid crisis large scale support programs for firms in Western economies were set up to avoid bankruptcies. Similarly, during the sovereign debt crisis in the Eurozone, the European Central Bank (ECB) set up large scale asset purchase programs as well as additionally longer-term refinancing operations (LTRO) which provided immediate support to financial market participants’ liquidity positions and thereby prevented a melt-down of the financial system. During these periods, immediate and abundant liquidity supply is of utmost importance. Meanwhile, crisis measures, due to their massive scale and non-specific target group, may entail unknown or unintended side effects for instance on competition among market participants, firms’ investment behavior, or changes in lending strategies and risk taking behavior of banks. Likewise, new regulatory frameworks such as the introduction of new markets can have consequences previously not thought of. For policy makers it is important to know direct effects of policy interventions but also to be aware of the possibility and impact of indirect or unexpected side effects in order to evaluate measures taken and to learn for future design of regulation or intervention.

We evaluate alternative indicators of global economic activity and other market funda-mentals in terms of their usefulness for forecasting real oil prices and global petroleum consumption. World industrial production is one of the most useful indicators. However, by combining measures from several different sources we can do even better. Our analysis results in a new index of global economic conditions and measures for assessing future energy demand and oil price pressures. We illustrate their usefulness for quantifying the main factors behind the severe contraction of the global economy and the price risks faced by shale oil producers in early 2020.

Die Weltwirtschaft ist auch im Sommerhalbjahr verschiedenen schweren Belastungen ausgesetzt, die die Preise stark steigen lassen. Produktionsstilllegungen im Zuge der chinesischen Null-Covid-Strategie und der Angriff gegen die Ukraine heizen die Inflation weltweit an. Auch in Deutschland wird die konjunkturelle Entwicklung durch die mit dem Krieg verbundenen Preissteigerungen sowie unterbrochene Lieferketten schwer belastet. Die konjunkturellen Aussichten für den Sommer sind trüb. Das deutsche Bruttoinlandsprodukt wird im Jahr 2022 um 1,5% zunehmen. In Ostdeutschland liegt der Zuwachs bei 1%.

In economic theory, entrepreneurship is perceived as a driving force behind the process of creative destruction by introducing innovation to the market, crowding out inefficient businesses, and paving the way for economic growth. One central channel through which entrepreneurial activity can be realized is the founding a new firm (Carree & Thurik, 2003). Numerous empirical studies have investigated the causes of firm entry, the subsequent fate of these young businesses, and their impact on the economy (Geroski, 1995; Wagner, 2006). When assessing the importance of start-ups for economic development, their role in the creation and destruction of jobs is a key component. This thesis argues that start-ups’ role as employers should be evaluated not only by the quantity of jobs they create, but also by the quality of these jobs. If new firms differ from incumbents in terms of hiring patterns or employment conditions, this could have serious and long-lasting implications for the careers and personal lives of their employees. Against this background, the four essays of this thesis present new evidence on the hiring behavior of newly founded establishments, as well as on remuneration and employment prospects of workers joining a start-up.

In der vorliegenden Studie werden zunächst die weltweiten konjunkturellen Aussichten für das Ende des Jahres 2021 und für die Jahre 2022 bis 2026 dargestellt. Dabei wird folgender Länderkreis betrachtet: Deutschland, Frankreich, Griechenland, Großbritannien, Irland, Italien, Niederlande, Polen, Portugal, Slowakei und Spanien.

We study the impact of sovereign solvency on the private-public savings offset. Using data on 80 economies for 1989–2018, we find robust evidence for a U-shaped pattern in the private-public savings offset in sovereign credit ratings. While the 1:1 savings offset is observed at intermediate levels of sovereign solvency, fiscal deficits are not offset by private savings at extremely low and high levels of sovereign solvency. Particularly, the U-shaped pattern is more pronounced for countries with high levels of foreign ownership of government debt. The U-shaped pattern is an emerging market phenomenon; additionally, it is confirmed when considering foreign currency rating and external public debt, but not for domestic currency rating and domestic public debt. For considerable foreign ownership of sovereign bonds, sovereign default constitutes a net wealth gain for domestic consumers.
