A behavioral finance: An analysis of investment decision making regarding psychological influences
(2016)
Anywhere humans are interacting, emotions and psychology are important determinants to consider. This statement is true for financial markets as well and often there are occurrences which are not explainable by using traditional theories. Therefore, behavioral finance aims at finding explanations for such occurrences, referred to as anomalies, by combining economic and psychological research. The literature review presented in here shows recent developments in the field and gives an overview of research evidence by reviewing studies from six of the most investigated facets of behavioral finance. The review includes evidence from a variety of studies performed in different contexts to disclose the importance of understanding human behavior, especially in terms of financial markets and economy. The closure of this review consists of an alternative model and concludes that there might be a new science entering the collaboration between economists and psychologist which is computer science.
A Coherent Set of Customer Experience Factors for the Developers of Industrial Product Services
(2016)
This study examines growth adventure of Turkey and South Korea that both tried to narrow the economical gap between them and developed countries. Although Turkey was in a better situation than South Korea in the beginning of their convergence experience, and they had similar growth and development levels at the end of 1950s, South Korea outperformed Turkey in almost every economic indicator and realized an economic miracle in a very short time. As South Korea is one of developed countries now and Turkey is still in the league of developing countries trying to be a developed one, South Korea model, is worth to be analyzed in detail. In this paper, the similarities and differences in South Korea’s and Turkey’s economic history, the comparison of their long term growth performance and the reasons why Turkey could not accomplish what South Korea did in the similar period of time, were put together in order to find answers to question of applicability of South Korean economic miracle to other economies, along with the question whether it was indeed a miracle. While comparing two countries, existing literature and similar studies were scanned. With the help of both qualitative and quantitative historical data, common issues of comparison, namely policies, international trade, education and innovation, were selected and these issues were analyzed deeper. In the last part of the study, a simple econometric model was built by using OLS regression, in order to see if the presented ideas could be supported with econometric approach. Although model did not provide enough information about reasons of growth in South Korean economy, the findings confirmed the problems of Turkish economy and success of South Korean economy. This study is a contribution to a broader understanding of comparison of two economies, which is an issue that attracts attention of several related people, especially in Turkey.

The main purpose of this qualitative study is to investigate the customers’ motivation to participate in SAP‘s Influencing Programs and to subsequently generate suggestions for possible improvements.
The framework for the domains of interview design, analysis of conducted interviews, as well as the analysis of secondary sources is presented by theoretical analysis of both the involvement of business-to-business customers in the innovation process as well as the nature of motivation.
Empirical findings show that customers’ motivation to participate in SAP IPs consists of, in descending order of importance, the following motives: Influencing functionality, understanding functionality, learning about future functionality, contact to SAP, and contact to other companies. The design of SAP’s Influencing Programs is generally in line with the motivation of participating customers. Still, improvements could be realized in terms of customer involvement during the selection process, internal alignment between different Influencing Program teams, and mandatory training of Influencing Program moderators.

A Successful introduction of E-learning for Bosch Car Service and Auto Crew Workshops Worldwide.
(2016)
The purpose of this study is to determine how to introduce E-learning successfully for Bosch soft franchise workshops to maintain quality in services and a high level of customer satisfaction. The study focuses on two research question A) Should Bosch continue to invest in producing elearning course for workshops. B) How to increase workshop’s participation for e-learning. Regional Concept Managers from 14 countries evaluated the existing e-learning courses to define exclusively “E-learnings” pro and cons as per their marketplace to see if investing in elearning is beneficial. Secondly, the emphasis was placed on Regional Managers to brainstorm on what are the new strategies can be used to motivate the workshop to take part in e-learning. Broadly speaking, learning is an expensive and time-consuming activity that can be a disadvantage when it comes to teaching people. Bosch was one of the pioneer company after Daimler that uses e-learning platform to train their workshops- Bosch car Service and Auto Crew. The vision for e-learning was very innovative and useful for the workshops to teach the structured way of showing all the works that carried out in a workshop. However, low participation from the workshop in e-learning courses has been a challenge.
The first part of the thesis provides a theoretical understanding of the Automotive Aftermarket. It also gives detail introduction and usage of “E-learning” in 21st century. The second part explains the workshop concepts “Bosch Car Service” and “Auto Crew.” It also provides an overview of “how e-learning course is produced and used for workshops” and the final part consists of an “Empirical Research” that includes the findings from Expert Interview and survey with Regional Managers. The findings from empirical part reveal that E-learning courses are useful for the workshop. Therefore, Bosch should continue to invest in producing E-learning Courses. However, study shows the different areas that need improvement, therefore findings from the empirical research need to be considered by the Headquarter as well as the Regional Organization to successfully introduce “E-learning” for the workshops.
Acid Sphingomyelinase Promotes Endothelial Stress Response in Systemic Inflammation and Sepsis
(2016)
This study belongs to the field of innovation research and is based on the application of a theoretical concept of a technology acceptance. The theoretical concept developed in the context of this research work is investigating the connection between efficiency, quality, security and business process re-engineering and the intention to adopt mobile payments technologies by merchants within the retail industry. Mobile payments is an emerging topic which is currently experiencing a rise. Although there are significant differences in a level of mobile payments acceptance around the world, the widespread adoption of the technology has not prevailed yet. Moreover, more research is needed to investigate and explain retailers’ prospective on the mobile payments adoption. The growing scientific interest in this topic is relevant in terms of innovation development, theories of global competition platforms and evolving landscape of global payment systems.
From this holistic prospective the fundamental hypotheses and crucial questions in terms of mobile payments adoption by merchants were derived. The analysis of the data sample of 90 companies of various sizes and operating in different industries obtained by means of a survey conducted at one of the largest trade fairs in Munich, Germany in autumn 2015. The data was analyzed using descriptive univariate and multivariate methods and the significance of the conceptual framework was validated. A major positive trend in mobile payments adoption was indicated. The findings of this research suggest that efficiency had a significant positive influence on the intention to adopt mobile payments by merchants. Banks and credit card companies were recognized as the most preferred mobile payments providers among retailers with an increasing interest towards independent companies. Based on the findings, the scientific guidelines for the future research were outlined and the concrete recommendations from the managerial prospective for achieving a successful adoption of mobile payments among merchants were suggested.
Advanced sales approach to increase professional fairs participation: international experience
(2016)
The following bachelor thesis was written in cooperation with Hannover Fairs USA, Inc. (HFUSA), which is the Deutsche Messe AG’s (DMAG) U.S. subsidiary. DMAG in Hannover, Germany, is one of the biggest and most active event organizers in the world. The target region of the HFUSA office is North America. Their function is to host industrial trade shows in Chicago and to sell exhibit space at their parent company’s shows in Germany to American companies. The focus of the thesis will be on the DMAG’s CeMAT show which serves the intralogistic and material handling industry. The topic of the thesis is ‘Evolving a structured and advanced sales approach to enhance the number of American companies, participating at the Deutsche Messe’s CeMAT show.’ The research focus is on the intralogistic and material handling industry, the meaningfulness of trade shows and various skills and processes of sales theory. Furthermore, it places emphasis on corporate and sales strategy. The thesis offers possible measures which should serve c-level employees of the company as a basis for creating a more standardized corporate, marketing, and sales strategy to streamline the process amongst employees, to enhance sales processes, improve efficiency and therefore increase revenue in the long run. This will also positively influence the process of achieving their goal of enhancing the number of participating U.S. companies at the CeMAT show in Hannover.

Aim: The research aims at contributing to the growing number of studies on banking performance by investigating empirically the effect of changes in the macroeconomic conditions on bank profitability in Europe for the period 1980-2009. For this purpose, data for banking systems of eight European countries on an aggregate national level are included in the analysis: Germany, France, Austria, Norway, Netherland, United Kingdom (UK), Spain and Italy. In addition to this, two measures are used to represent the bank profitability: net interest income (NII) and return on assets (ROA).
Methods: Panel regression models at three levels are deployed in order to estimate empirically the effect of the macroeconomic indicators on bank performance in Europa: individual estimations on a country level, cross-country estimations on a group level for Northern and Southern Europe and finally overall cross-country estimation on a European level.
Results: The estimation results suggest that macroeconomic conditions are able to explain most of the variation of the banks’ net interest income in European countries, as well as part of the variation of banks’ ROA. Additionally, they clearly indicate that GDP growth rate is the most significant factor influencing bank performance in Europe on all three levels of the model. The effect of the inflation rate is also considered for strongly significant and positive while the effect of the other macroeconomic variables included in this research is different and cannot be generalized probably as a result of the heterogeneity among European countries. Surprisingly, the results did not indicate any significant difference between Norther and Southern Europe, regarding the effect of the macroeconomic conditions on bank performance.
2016 marks the 56th anniversary of the oil cartel: OPEC. It managed to increase prices in 1972. In doing so, it behaved in a manner consistent with a cartel, bringing about a wave of studies on it. This study provides an overview of Organization of Oil Exporting Countries (OPEC)’s cartel behavior form 1980 to 2014/5, from five different perspectives. These perspectives, although have been studies individually, but never holistically.
This study grounds the research questions into the structure-conduct-performance paradigm for each of the five perspectives of cartel behavior. Each perspective is also backed by a theory of its own. The first perspective is that of the neo-classical theory of the firm, in that OPEC is deemed to be created for the purpose of creating profits for its members. The second perspective looks at whether or not OPEC is internally and externally stable by looking at economic and non-economic influences on the organization. The third perspective makes use of the theory of market contestability, in oder to determine which member in the cartel has had and still holds most influence within the cartel. The fourth perspective looks at entry and exit trends from OPEC, to determine what impact it has on the incumbent profits and that of the defectors. The fifth perspective uses the concept of black swan from the strategic management literature to discuss whether or not OPEC will dissolve in the next fifty years and whether this will bring about a golden or a black swan.
The methodology prevalent throughout the study is a case study analysis of the OPEC cartel behavior, however, two of the chapters also run a regression analysis (chapters 3 and 4), using variables identified from the structure-conduct-performance paradigm. The second and the third provide a descriptive overview via line graphs, while the last uses the methodology of observation.
It has been found that OPEC has earned abnormal profits which steadily increased, Saudi Arabia has been instrumental in managing quotas, and importance of each country is determined by the output it produced from one year to the next. In addition, economic influences are more important than the non-economic influences for OPEC's viability as a cartel, exit from OPEC is not advisable for the defector nor the incumbent firms and the cartel is not internally stable as barriers to entry are low and members can easily defect and can rejoin the cartel. Lastly, OPEC’s influence in the oil market is waning fast, which might lead to a black swan event.
The research is the basis for a recommendation for an advantageous positioning of the research sponsor in its business line corporate banking on the issue; the business of sustainability with corporate clients. Simultaneously it gives an impression about the positioning of the research sponsor’s competitors in this business. The research is structured in three research questions; “How do ING WB and its competitors differentiate in their positioning, what are the needs of the clients a corporate bank is serving and how far are the actions of ING WB and of its competitors in consistence with what they are communicating?” The research questions are composed based on a positioning model. The outcome of the research questions provides data needed to formulate the recommendation for ING WB’s positioning. The research is comprised of a comparative analysis based on a desk research and secondary data analysis. The study revealed that the positioning of banks differ slightly from each other. Therefore a good positioning, which can be achieved by taking the outcome of the three research questions into consideration, is advantageous to be able to stand out in a competitive business.
The field of entrepreneurship and its framework, the entrepreneurial opportunity process, are still young and maturing research areas that receive increasing attention from numerous authors in their academic reviews. While some researchers focus on the generic entrepreneurial opportunity process in order to gain additional insights into the phenomenon, others examine one of the entrepreneurial directions, such as social entrepreneurship or commercial entrepreneurship more closely. So far, a dichotomous approach towards the two types of entrepreneurship has been postulated by contemporary researchers that distinguishes them as two varying approaches.
This master thesis comprises both entrepreneurial directions and investigates their course throughout the entrepreneurial opportunity process, including the nature of the opportunities, their discovery and the decision to exploit an opportunity. The aim is to get a broader picture of the phenomenon of social and commercial entrepreneurship, its differences and similarities throughout the process and thus, examine the dominant dichotomous approach.
Primary and secondary data is gathered from case studies and interviews with entrepreneurs and derived from the information obtained, as well as from existing literature. Seven propositions are postulated that indicate possible differences and similarities regarding the two entrepreneurial approaches. Based on the findings from the testing of the propositions, this research paper concludes that the concepts of social and commercial entrepreneurship hold certain differences, Nevertheless, similarities are prevailing so that a dichotomous approach cannot be supported. The entrepreneurial directions can be displayed on a continuum rather than on extreme ends.
Finally, in order to provide possible future research objectives, an outlook section, containing a critical view on the tie between the entrepreneur and the opportunity is enclosed. It is suggested that the entrepreneur-opportunity nexus is much stronger in the social entrepreneurial context than in the commercial entrepreneurial context.
Cost accounting is one of the main sources of information for the management in the company. A correctly designed cost accounting system may address the most important issues in order to support effective and successful decision-making, which among others include price building, efficiency measurement and profit evaluation. In order to enable the full functioning of the system the company should ensure that the system is designed according to the company’s size, operations and processes, as well as information needs. For Testo Sensor GmbH the optimization of cost accounting system became essential, as the information it provides at the moment is not sufficient and reliable for decision-making. Obviously, the reason for this is that the system was not correctly and thoroughly designed at the times of the company foundation. Therefore, the goal of current paper is to develop and adjust the cost accounting system to the company’s operations in order to fulfill the information needs. In order to reach this goal the following objectives were defined: to analyze the current state of cost accounting system of Testo Sensor to reveal its weaknesses and incompatibilities to address these incompatibilities by developing the improvements and possible optimization potentials In order to fulfill these objectives, the review of the German and English literature on the current topic was made in order to identify possible approaches and methods and provide a theoretical background for solutions of the existent problem. In addition to this, a number of interviews was held with the employees of Testo Sensor, as well as the parent company. Finally, the exact data for 2011 – 2015 for cost analysis was taken from the company’s database systems and other documentation. The result of the current paper represents a number of the optimization potentials, which relate to all elements of the cost accounting system. In addition to this, a proposal for implementation of cost center planning and control, which currently is not implemented in the company, was designed. The optimization proposals were developed with the consideration of the theoretical methods applied in German companies, as well as the company’s particular needs and possibilities.

Automated Advisory Services. An investigation of Efficiency on Using the Black-Litterman Model
(2016)
This thesis seeks to investigate efficiency of current portfolio theory, using the Black-Litterman Model, for creating portfolio recommendations as offered by Automated Advisory Services. These services have recently appeared, offering wealth management through a digital store front. As the human component has been removed from the equation, algorithms based on portfolio theory provide portfolio recommendations upon profiling the user of such services. Tests on parameters of the Black-Litterman Model will be run between September 2007 and December 2009, the financial crisis. The aim is to understand how efficient the parameters are able to steer the model to reflect the investor preferences, and how Black Litterman portfolios would have performed during turbulent economic times to test the efficiency claim by providers of automated advisory services.
This paper analyzes automated advisory services, a new business model developed by Fintech start-ups in the USA. The markets for automated advisory services (AAS) in the USA, where it is most established, and in Germany, where the market is still in the infancy stage, are examined and compared. The aim of the paper is to identify the market conditions determining user acceptance of automated advisory services in the USA and comparing the German market conditions to the US market in order to predict consumer acceptance in Germany. The markets are examined using the PEST analysis and Porter´s five forces framework. Recent market data, mainly from online media like online newspapers and studies, is collected and applied to the models. The data reveals that the market conditions for AAS are similar in both markets but in Germany there are some negative factors restraining growth. The second part of the paper is a technology acceptance analysis of automated advisory services using the UTAUT2 model. The UTAUT2 model is first applied to and extended for the automated advisory services market. Afterwards, the market data is applied to the model, confirming that the market data and theoretical framework of the model are conform. Finally, an outlook into the future of AAS in Germany and the USA is given, showing that the German market has the potential to develop similar to the US market once the negative influences on technology acceptance are diminished Further research into the aspects individualization of automated advisory services, web 3.0 applications and security of the algorithms and user data should be conducted.
