Die Forschungsaktivitäten des Lehrstuhls für Finanzierung sind zentral im Bereich der Finanzwirtschaft verankert und ergeben sich als Schnittmenge aus den Bereichen „Corporate Finance“, „Corporate Governance“ sowie der empirischen Kapitalmarktforschung. Methodisch basieren die Forschungsarbeiten überwiegend auf empirischen Ansätzen, wobei der Markt für „Corporate Control“ und die Auswirkungen von Veränderungen in der Eigentümerstruktur auf die Performance und Führung von Unternehmen, gestützt auf die Prinzipal-Agenten-Theorie, einen inhaltlichen Schwerpunt der zahlreichen Forschungsaktivitäten bildet.
Vor diesem Hintergrund zählen auch Familienunternehmen, die sich insbesondere durch eine konzentrierte Eigentümerstruktur auszeichnen und bei denen die Gesellschafterfamilie durch ihre prominente Stellung einen starken Einfluss auf die Unternehmensstrategie und -politik nehmen kann, zu den Forschungsinteressen des Lehrstuhls. Weitere zentrale Forschungsprojekte befassen sich mit der Analyse von Kapitalstrukturen und Investitionsverhalten von Unternehmen sowie wesentlichen Fragen des Corporate Risk Managemts, die im Zusammenhang mit der Liquiditätshaltung stehen. Aber auch Forschungsfelder, die sich mit Veränderungen der Kapitalstruktur und damit einhergehender Implikationen für die Unternehmensführung befassen sind von besonderem Interesse. Neben großen kapitalmarktfähigen Unternehmen, sind auch verstärkt kleinere und mittelgroße, nicht-börsennotierte Unternehmen Gegenstand der Forschung.

Die weltweit schnell wachsende Finanztechnologie-Industrie und die Vielzahl an neuen Produkten, Dienstleistungen und Geschäftsmodellen bieten für KMUs einen vereinfachten Zugang zu Finanzierungsquellen und Finanzdienst-leistungen und bergen für etablierte Finanzintermediäre zugleich die Gefahr, sie aus einzelnen Segmenten zu verdrängen, zumindest aber den ohnehin schon hohen Margendruck weiter zu verstärken.

Over the past eight years, Claudia Nagel has worked extensively on the development of the theory and practice of the emerging field of Behavioral Strategy. Due to her practical Corporate Finance Background her work and research are also closely tied into Behavioral Corporate Finance.

She has also published several articles in the field of Behavioral Strategy in renowned journals and books.
Utilizing her active experience in strategy development, implementation and change processes, Claudia Nagel has further developed the theory base - which to date has focused more on cognitive aspects such as cognitive biases – through the integration of psychodynamic and neuro-scientific insights.

Hidden Champions or Black Sheep? Evidence from German Mini-Bonds
This paper presents a first empirical examination of all available German mini-bond offerings between 2010 and 2015. We compare the default probability according to a mini-bond’s initial rating with that implied by credit risk models, and show that rating agencies can create ratings inflation by issuing overly favorable ratings. This creates a “window of opportunity” for lower-quality firms to compete for funding. In this environment, high-quality firms have an incentive to use mini-bond underpricing to signal their quality. Our data highlight that, according to information-based corporate finance theory, higher underpricing is correlated with higher-quality mini-bond issuers and lower early default rates.

The Role of Sovereign Wealth Funds as Activist or Passive Fund Managers
Sovereign Wealth Funds (SWF) have attracted a lot media attention with recent investments in publicly listed companies. Repeatedly, concerns have been raised, such as the fear of industrial espionage or geopolitical threats. We analyze whether SWF managers acquire stakes in foreign publicly listed firms 1) to play an active role which would support concerns or 2) passively select investments to increase the portfolio diversification, for instance. We find that SWF target firms are more profitable, pay higher dividends and have a higher financial stability than their industry peers. This is in line with SWF managers passively seeking for further portfolio diversification in foreign public equity markets. We cannot find an improvement in operating or market performance after the engagement of SWF. Overall, our results indicate strong evidence that SWF managers primarily act as passive investors instead of pursuing activism strategies like private equity funds.

Intra-Industry Effects of Shareholder Activism in Germany - Is There a Difference between Hedge Fund and Private Equity Investments?
We investigate the valuation effects of industry rivals on German firms targeted by hedge funds and private equity investors. We argue that both types of investors differ from other block holders due to their strong motivation and ability to actively engage and monitor. We find that the announcement of a change in ownership structure generates statistically significant short- and long-term intra-industry effects for rivals to the respective private equity and hedge fund targets. However, these effects differ markedly between hedge fund investments and private equity investments. We conclude that hedge funds are more aggressive than private equity investors in implementing a shareholder orientation.

Hedge Funds versus Private Equity Funds as Shareholder Activists in Germany – Differences in Value Creation
We investigate the valuation effects of German firms targeted by hedge funds and by private equity investors. We argue that both types of investors differ from other blockholders by their strong motivation and ability to actively engage and reduce agency costs. Consequently, we find positive abnormal returns following a change in ownership structure. However, these effects differ markedly between both investors, as proxy variables for agency costs only explain the market reaction for our private equity subsample. We conclude that private equity funds seem to be more successful at creating shareholder value, which could be due to their longer-term perspective and a higher adaptability to the surrounding corporate governance.
