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 study seeks for empirical evidence supporting the presence of weak form ans semi-strong form efficiency on the Vietnamese stock market. The sample includes the daily closing value of VN-index from 9th April 2009 to 3rd of December 2014. The results from both parametric and non-parametric tests provide the evidence, which implies the weak form efficiency in the Vietnamese stock market during the recent period from 4th June 2012 to 3rd December 2014. This period is used for testing the semi-strong form efficiency on the Vietnamese stock market. The results from event study do not support the semi-strong form efficiency in the Vietnamese stock market. The empirical evidence shows a delayed reaction of nine pharmaceutical companies' stock prices toward the earnings, dividend, insider trading and regulatory announcements. The findings in this paper are crucial for investors, analysts, academicians, regulators and the development of the Vietnamese stock market.

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 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.
