Private equity investors acquire companies, aim to increase the company’s corporate value and thus aim at selling the respective company at a profit after some time. To increase the value of their portfolio companies, private equity investors employ three main value creation strategies. Financial leverage, multiple expansion, and operational value creation. There has been a significant shift in importance between these three value drivers. While in the 1980s more than 50% of value creation was achieved by leveraging equity with the help of debt capital, this value driver only accounted for 15% in the 2010s. Instead, the value driver operational value creation has gained significantly in importance. It alone accounted for 55% of total value creation in the 2010s, more than financial leverage and multiple expansion combined. The aim of this thesis is to answer the question which operational value creation levers private equity investors use to increase the value of their portfolio companies during the holding phase. In addition, the thesis deals with the question of operational value creation drivers of the future. These are derived based on prevailing megatrends of the future. Research on the operational value drivers used by private equity investors revealed that these drivers can be assigned to three main aspects.
These aspects are, on the one hand, financial aspects, where private equity investors take measures to improve working capital. Moreover, within the framework of financial aspects private equity investors influence the cost structure as well as the cost of capital and the capital structure. Furthermore, private equity investors assert influence on the governance structures of their portfolio companies. For the aspect of governance, measures such as replacement of management/change of management structure, monitoring and controlling as well as incentive systems were identified to increase the value of the company. Another identified aspect for value creation are strategic aspects. In terms of strategic aspects, private equity investors use the levers of mergers and acquisitions, organic expansion, outsourcing/insourcing as well as product and pricing strategies.
The research on the value creation levers that private equity investors will have to apply in the future in order to ensure value creation of their portfolio companies is based on the megatrends of digitalization, demographic change and sustainability. The research revealed the implementation of digitalization measures, employee, and talent management as well as the implementation of ESG criteria.
This thesis has structurally outlined value drivers that contribute to value creation in private equity investments. The research also showed that value creation levers taken can directly and indirectly influence the value of the portfolio company. Value drivers II with a direct effect on the change in equity value affect either revenue, margin or net debt, while the indirect value drivers affect the valuation multiple.
Through an extensive review of the literature, a research gap was identified concerning the knowledge around diversity and its impact on personality types and their influence on group performance. Previous literature revealed that diversity is a popular determinant for group composition, since it encompasses many different meanings and interpretations. Researchers would rather focus on easily measurable elements such as age or gender, but few studies have been conducted on deep-level diversity, such as personality traits or values. The aim of this study is to answer the research questions proposed concerning the effectiveness of homogeneous versus heterogeneous groups as well as the impact communication has on their performance. Through an analysis of previous studies and literature the research questions and hypotheses were formulated, and a methodology designed to answer them. The methodology used in this research was a variation of the Marshmallow Challenge. The groups were faced with two challenges. The first one was to build a 50cm-tall structure as quickly as possible, with a limited amount of material, including raw spaghetti, tape, rope and a marshmallow to test the stability of the structure. The second challenge was presented about one week later and involved the same materials, but the participants had to reach 70cm. Four teams of three were chosen. The personality tests had four possible outcomes: red, green, yellow, or blue. Each colour had specific characteristics and adjectives associated with it. The data collected revealed that the heterogeneous groups performed better overall. A slightly significant correlation was found between how well the teams performed and the words spoken per minute for the first experiment, but not for the second. The biggest limitation that hindered this study was the time pressure and limited sample size.
This paper analyses five different Cryptocurrencies, namely Bitcoin, Ethereum, XRP, Dogecoin and Litecoin, and studies their impact on traditional financial portfolios under different allocation strategies. The allocation strategies under consideration in this paper are the modern portfolio theory according to Markowitz, an extension of it such as the tangency portfolio, and the equally weighted portfolio. Further, this study explores the effect on the efficient frontier when Cryptocurrencies are added to the efficient portfolios. In addition to that, the paper aims to examine whether the mean – variance portfolio optimization according to Markowitz outperforms the naïve and tangency portfolio strategy. The portfolio performance is evaluated based on the Sharpe ratio. The quantitative analysis of this paper covers the time period from 2017 to 2022, in total five years. In accordance with the existing literature on portfolio optimization with Cryptocurrencies, the study reveals that besides some issues related with Cryptocurrencies such as cybercrime and a lack of regulations, Cryptocurrencies can be beneficial for portfolio diversification with traditional financial assets. Referring to the portfolio strategies, the study highlights that the optimal mean – variance portfolio and tangency portfolio do not differ significantly in terms of Sharpe ratio. However, both strategies outperform equally weighted portfolios.
In der heutigen Wirtschaftslage ist es für Unternehmen zunehmend wichtig sich aufgrund von einem zunehmend gesättigten Markt und steigendem Wettbewerb klar zu positionieren. Eine Grundlage für das strategische Marketing kann zum Beispiel durch ein Marketingkonzept geschaffen werden. Es dient als Leitfaden für weitere unternehmerische Marketingaktivitäten. In der vorliegenden Arbeit werden die Grundlagen für ein Marketingkonzept analysiert und aufgezeigt, mit dem Fokus auf der Kommunikationspolitik. Für die Ausarbeitung wird beispielhaft ein Produkt des kroatischen Unternehmens Terra Marascae d.o.o. verwendet. Die Kommunikationspolitik ist auf den unternehmenseigenen Online-Shop sowie die Gewinnung von Neukunden ausgerichtet. Die Informationen werden anhand des AIDA-Modells gewonnen. Auf dieser Grundlage kann die Kommunikationspolitik des Marketingkonzepts weiterführend abgeleitet werden. Dazu wird in Interviews sowie theoriegeleiteter Konzeption konkret ausfindig gemacht, welche Informationen für den Kunden und dessen Kaufprozess relevant sind. Die Ergebnisse der Studie zeigen, dass es wesentlich ist, die Besonderheiten der Produkte in der Kommunikationspolitik klar zu kommunizieren.
The purpose of this thesis is to examine how process mining might enhance and benefit processes to increase the competitive advantage, while also examining the difficulties businesses are facing when implementing process mining and the purpose for which they have implemented it. Presentations of cases from various industries are backed up by in-person interviews with representatives of various businesses. The findings show that process mining is a tool that users highly recommend since it produces results that have never been seen before, regardless of the field in which it is used and regardless of their initial purpose for choosing such a concept. It also emphasizes the importance of the staff and people in putting a new idea into practice, as well as their obstacles embracing anything new.
Businesses that are competing for an advantage knock on many doors. The last ten years have seen many businesses of all kinds open their doors to process mining. A notion that identifies their shortcomings, provides them with room to grow and gives them transparency. One would assume that firms' focus is on keeping costs low in today's environment, where expenses climb enormously daily, therefore that's why they introduce innovative concepts. That may be true at first, but once the concept's genuine usefulness is realized, their focus is simple to change. Companies today recognize the need of process optimization if they wish to operate with a competitive edge and have a sound business plan. Until businesses decide to test the idea themselves, the network effect is important in such situations.
Since the concept hasn't been on the market for very long and not many companies have had experience with it thus far, it was observed that the results of the literature review with regard to the content of the interviews were practically comparable.
Finally, this paper provides recommendations for a transition from the conventional business models that firms are still using to more modern technical, data-based approaches. Only a broad analysis and conclusion are possible with the sample size of eleven companies and ten specialists.
In two experiments, this empirical research examines consumers’ willingness to pay and the likelihood of purchase decisions by thoroughly investigating the neural, behavioral, and psychological properties of packaging design. A general theory is tested by functional magnetic resonance imaging (fMRI) and a NeuroPricing online survey on consumer behavior using the example product Tassimo. Hypotheses are tested with 592 German consumers who evaluated the packaging of Tassimo coffee. A closer look at the neural data from the brain imaging experiment shows that uncertainty can arise among consumers with regard to sustainable packaging and this can have a negative impact on the purchase decision and willingness to pay. The results from both experiments show that it is not possible to make a holistic statement as to which sustainable or enjoyment-focused packaging design increases the likelihood of a purchase decision or the willingness to pay. Implications for future packaging design research and underlying complexities with sustainable packaging are discussed.
