There are two methods for evaluating two or more mutually exclusive projects. One is a total investment approach and the other is an incremental investment approach. The former can rank projects by the criterion of the net present value, but the latter can't do it. An incremental investment approach is only possible when all pairwise alternatives are compared. Thus an incremental investment approach is superior in ranking them over an incremental investment approach. To do so, a principle of comparison must be established. Comparisons of profitability are reasonable when operating the same amount of investment over the same period of time. One principle is that all projects are invested in the largest of the projects. Another principle is that all projects are invested during the longest project life of the projects. In this paper, even if the principle is followed, it will be shown that the external rate of return fails to rank them. However, the productive rate of return criterion would prove to be able to rank them like the net present value standard, provided that the principle of comparison is kept. In addition, rate of returns can be assessed so that all mutually exclusive projects can be compared at once, such as on the criterion of the net present value. That is, it can be also compared with many other returns, such as the profit rates on financial investments or real investments.

Nowadays the role of region has been increased, as knowledge, science and technology become important in economic development. This paper argues that a system approach is needed to enhance regional S&T capabilities. Under the this approach, we can identify a concept of regional innovation systems as sub-systems of a national innovation system. This paper investigates Korean regional innovation systems based on R&D budget of regional governments. According to this paper, Korean regional governments' R&D investment is very insufficient. There were no co-relationship between regional governments' fiscal autonomy from the central government and their R&D investment. This paper argues that such a poor investment will restrict the future development of Korean regional innovation systems. Therefore, this paper suggests some strategic options for the development of regional innovation systems as follows. First, regional governments should increase their R&D budget. Second, their R&D efforts should be related with their specific industrial sectors. Third, they should target not only to create new promising industrial sectors but also to enhance technological capabilities of existing sectors. Fourth, their target group should be small and medium-sized enterprises. Finally, regional governments should adopt small and incremental approach to improve their innovation systems.

There are two approaches for evaluating two or more investment projects. One is a total investment approach and the other is an incremental investment approach. We present that ranking projects by the latter is not sufficient for an investor to accept the next best alternative. We prove that ranking projects by the former is superior to that by the latter. We also prove that the ranks obtained by the criteria like ORR and B/C ratio are consistent to the ranks by DCF criteria. However the result is different when IRR is adapted.

The R&D productivity has the same meaning as that of general meaning. Its input includes budget, facility, schedule, idea and target, and its output includes patent, paper, technological innovation and revenue increase and technology accumulation influenced by these factors. The choice of R&D item which will have the large effectiveness after customization, resource input of proper level, application of efficient development schema, effective usage of development output, objective appraisal for the R&D output and extension for the future project are the main factors for which is suggested to enhance the R&D productivity. The management's expectation for R&D can be represented as the innovativeness of output and potential influence to outsiders. The speedy output, even if incremental investment more than planning happens, will eventually result in the productivity enhancement of the enterprise, and managers must not encounter the opportunity loss in return for the excessive investment control.

본 연구는 실물옵션모형을 이용하여 기업의 빅데이터 기술도입에 따른 경제적 가치를 분석한 연구로, 빅데이터 기술도입을 결정한 기업의 주가를 이용하여 주가증분으로 평가한 경제적 가치의 크기를 옵션가치를 통해 분석하였다. 옵션가치 도출을 위해 빅데이터 기술을 마케팅에 활용한 기업의 주가를 통해 빅데이터 기술에 의한 주가증분을 추출하고, 해당 주가로 일반화적률법(GMM)을 이용하여 확률과정을 추정하였다. 옵션가치 도출을 위해 블랙-숄즈 편미분방정식을 도출하였고, 이를 수치해석적 방법인 유한차분법으로 해를 구하여 빅데이터 기술 도입에 따른 경제적 가치를 추정하였다. 분석결과, 빅데이터 투자비용을 5천만 원으로 가정했을 때, 주가증분을 통해 도출한 옵션가치는 약 38.5억 원으로 나타났고 시간가치는 약 1백만에 해당하는 것으로 나타났다. 따라서 빅데이터 기술도입은 실질적인 기업의 수익을 창출하는 효과에 더하여, 미미하지만 투자시점에 고려할 수 있는 추가적 시간가치까지 존재하는 것으로 해석된다. 민감도분석 결과 기초자산 크기가 작아질수록 옵션가치는 낮아지고, 투자비용이 낮아질수록 옵션가치는 높아지는 것으로 분석되었고, 변동성 변화에 따른 옵션가치 민감도는 크지 않은 것으로 나타났는데 이는 빅데이터 기술의 경우 기술도입 기간과 이에 따른 주가변동 폭이 낮아 변동성 증가에 따른 내재가치 증가 효과가 크지 않기 때문인 것으로 해석된다. 본 연구는 빅데이터 기술도입에 따른 효과를 실물옵션을 도입하여 분석한 최초의 연구로 빅데이터 옵션가치 도출에 빅데이터 기술을 도입한 기업의 주가를 기초자산으로 사용한 최초의 연구라는 점에서 기존연구와 차별화된다. 기업들의 빅데이터 기술 도입이 비교적 최근에 발생하였음을 고려할 때 동 분석방법론을 다양한 기업에 적용함으로 빅데이터 기술의 정체한 가치를 도출하는데 기여할 수 있을 것으로 기대된다.

Purpose - to examine the theories related to the internationalization of multinational corporations as well as theories related to internationalization of small and medium-sized enterprises. Research design, data, and methodology - traditional theories, e.g. eclectic paradigm and behavioral theory and product life cycle etc. were examined and recent advances theories - network theory, entrepreneurship - were also examined to outline the theory of internationalization of firm. Results - the main schools of international researches are divided into two; one is the economics school, the other is the behavioral school. The economics school has considered internationalization as a pattern of investment in foreign markets explained by rational economic analysis of internalization, ownership, and location advantages. Apart from the economics approach, a theory relevant to smaller firms highlights slow and incremental overseas market commitment. Recent research on the network perspective is fast emerging and it can be applied and well explained on the internationalization of smaller firms, focusing on firm behavior in the context of a network of interorganizational and inter-personal relationships Conclusions - Small medium-sized enterprises have been recently rising, however, there has still been little consolidation of literature in internationalization and most of the relevant theories have been still focusing on explaining the globalization of multinational corporations. Little studied on the internationalization in the context of smaller firms which are distinctly differentiated from larger firms including international new ventures, which the motivation to study strongly calls for more information and studied on small medium-sized enterprises.

We present a unified explanation of the internationalization strategies of major mobile network operators (MNOs). We have developed a framework that analyzes the strategies of major international MNOs in terms of the relationship between their degree of involvement in international business operations and the degree of equity participation. The results show a positive association between these two dimensions as expected, but they also reveal some exceptional cases in which certain MNOs are actively involved in the business operations of other foreign MNOs, even with minor (or zero) equity investments. In this paper, we argue that the strategic actions of the major MNOs which are the largest shareholders of foreign MNOs are in an equilibrium status because these major MNOs derive maximum benefit from full or considerable management control and active involvement. Finally, we predict that latecomers (MNOs who are just about to enter foreign telecommunications markets) may adopt an incremental investment approach because most developed markets and deregulated emerging markets with growth potential are already preempted by major MNOs. Therefore, the window of opportunity for internationalization in those markets is currently small.

Purpose - This study is to verify the impact of the documentation of key audit matters on the value relevance of accounting information in accordance with the revised accounting audit standards in 2017. Investors will be able to identify the company's significant financial risks through key audit matters and use them to make investment decisions. Design/methodology/approach - From 2011 to 2019, the final sample is 290, based on the December settlement of accounts listed on the securities market. Ohlson (1995) was used to verify the incremental link between net income and the book value as a determinant of corporate value. Findings - First, the key audit matters in the financial industry was found to have a negative (-) effect that was significant to the value relevance of accounting Information. In addition, the value of the interaction between the key audit matters and the net income is a significant (+) relationship with the share price and the value of the interaction between the key audit matters and the book value is a significant (-) relationship with the share price. This means that the key audit matters is the determining factor of corporate value, positively reflects the accounting information in net income and negatively reflects the accounting information in book value. Second, among the key audit matters, the fair value assessment of financial instruments and the adequacy of premiums reserve have a significant impact on the value relevance of accounting information. Research implications or Originality - The results of this study suggest that investors recognize key audit matters as information about the company's major financial risks and reflect them differently in the value relevance of accounting information.
