This dissertation in the field of empirical financial economics broadly explores the interplay between monetary policy, debt securities markets and bank credit. Specifically, the three chapters of this dissertation share two major themes, debt capital structure and the effects of central bank policy. Chapter 1 studies a determinant of the corporate debt capital structure and it finds that the rise of universal banking conglomerates contributed to the increase in bond financing in the U.S. The article of Chapter 2 links the two themes by analyzing a mechanism that describes how the corporate debt structure influences the transmission of central bank policy to the real economy. When central banks purchase corporate bonds, purchase-eligible firms substitute bond debt for bank loans. This, in turn, frees up balance sheet capacity at banks that then start lending to firms without access to bond markets. Finally, chapter 3 is based on an article that examines to what extent central bank policy, among other causes, may be responsible for the low interest rates in recent years. It also analyzes the consequences of low interest rates and issues policy recommendations.

The article examines the risk of the proliferation of potentially harmful disinformation through 'oral' social media services such as Clubhouse. While false or misleading information may have fewer means to stick and go viral, it is also more difficult to fact-check speakers, which may create new vulnerabilities for the information ecosystem online.

The codetermination principle – as seen in the German corporate governance system – provides a solid foundation for achieving climate and sustainability goals. The involvement of employees needs to be coupled with more diversification parameters used for appointing non-executive directors as well as building sustainability expertise and proper incentives for acting sustainably. The Climate Governance Initiative in Germany among others can help non-executive directors in becoming stronger and even more capable sustainability ambassadors within their companies.

The article examines the first decisions issued by Facebook's newly established Oversight Board that deal with the exacerbating problem of health misinformation. In this context, it is questioned whether the Board's applied standard of 'imminent harm' is suitable for the problem at hand given the viral proliferation of potentially consequential false and misleading information about public health policies amid a pandemic.

In an age where manufacturers are challenged to increase production with fewer resources and get their finished products to market sooner, mature manufacturing systems envisioned by I4 promise to rev up production lines, help turn out goods faster, and crunch delivery times and cost .

In our respective fields as a management educator and actor-turned-executive-coach, we have accrued decades of experience in training business professionals to enhance their stage presence at work. When remote working became the rule rather than the exception, we came together to explore what the multi-million-dollar performing arts industry can teach us about mastering virtual communication.

How these companies embraced innovation to take the lead in their markets provides lessons for small and medium enterprises (SMEs) everywhere.

The legal implications of digital information warfare in the context of armed conflict have so far received only scarce attention. This paper aims at filling this gap by exposing some of the legal issues arising in relation to mis- and disinformation tactics during armed conflict in order to serve as a starting point for further debate in this respect:

What, if any, limits exist concerning (digital) information operations in armed conflict? Does the humanitarian legal framework adequately capture the humanitarian protection needs that arise from these types of (military) conduct? Where and how to draw the line between effects and side-effects of digitalised information warfare that should remain either within or without the protective ambit of international humanitarian law (IHL)? What are, or what should be, the limits of disinformation campaigns, “fake news”, deep fakes and the systematic manipulation of a given information space in times of armed conflict?
