In this study, the characteristics of the waste sector CDM project were analyzed through cluster analysis of the waste sector CDM project and the analysis of the CDM investment cost in waste sector using CDM project data registered with UNFCCC since 2008 when EU ETS phase 2 began. As of September 2020, 772 cases of CDM projects in waste disposal and disposal are registered. Biogas technology is the largest, followed by livestock manure processing and biomass production technology. The results of the cluster analysis are summarized as follows: First, on average, projects utilizing AWMS technology are small in size and relatively low in investment costs. This is judged to be relatively low investment costs due to previously attracted foreign investment capital. Second, the average investment cost of CDM projects considered along with waste (No.13), the energy industry (No.1) and agriculture (No.15) was higher than those involving only waste. The analysis of the factors determining the investment cost of the waste sector CDM project showed that, as with cluster analysis, the AWMS technology, which is a livestock manure treatment technology, was lower in the investment cost than those that use other technologies. As a result of multiple regression analysis, the investment cost of the CDM project was analyzed lower in the order of biomass, AWMS, LFG and biogas. Also, the higher the investment cost for CDM projects linked to waste, energy and agriculture, and the better the investment environment, the higher the investment cost. Although no statistical feasibility was obtained, the larger the annual emission reduction, the lower the CDM investment cost.

There has been investments by firms to protect workers' health and to improve their health status. Most of the investments are made on the ground of legal requirement. However many argue that the amount of investments made falls short of the legally required level. One of the reasons why firms are not active in undertaking required investments is that they are not certain whether such investment is economically beneficial to them or not. Using CBA (Cost-Benefit Analysis), this study investigates whether firms' investments on workers' health are economically justifiable or not. All kinds of expected costs and benefits are itemized and calculated, and costs are compared with benefits. The result shows that if firms fully undertake the legally required investments, total expected costs amount to W453.2 billion and expected benefits accruing to reductions from medical care costs, workers compensation costs, litigation costs in case of legal suit, work days lost, and etc. comes up to W2,086.8 billion. In other words, economic benefits from firms' investment on industrial health far outweighs their costs. As the economy grows, the probability of having various occupational disease increases. It is well conceivable from this study outcome that, the higher the probability, the greater the social loss would be, and the greater the benefits from proper investments on workers' health.

In the past vertically integrated power system, the power utility forecasted power demand and invested new power plants to keep a system adequacy. However, in the competitive electricity markets, a principle part of the capacity investment is market participants who decided the investment to maximize their profit. Especially, one of the main factors in their long-term decision making is the retrieval of fixed costs (construction costs). This paper presents the capacity payment in electricity power markets. The capacity payment (CP) in Cost Based Pool (CBP) is needed to recover fixed costs. However, CP in CBP was applied not only recovering fixed costs but also ensuring supply reliability. In order to operate harmonious power markets, pool needs reasonable CP mechanism. This paper analysis CP using capacity proportion and Reliability Pricing Model (RPM).

The world air transport industry has grown steadily with quantitative expansion. The volume of air transport in the world is skyrocketing with the open-sky trend. Air passengers from or to South Korea has shown 5% of annual growth for the last couple of decades which caused South Korea now ranking in 18th in the World for air transport market size. Quantitative expansion of Air transport affects in policy making of air transport operators, such as airports, airlines or authorities, directly and indirectly. Especially, Aviation Safety field should be supported by policy regime with the growth of air transport volume, assured resources for continuous monitoring is standing out as a vital factor. This study is to estimate social costs caused by aviation accidents and investment costs for aviation safety by airports, airlines and authorities as operators. Estimated investment costs for aviation safety verified by comparing and analysing them. Precedent studies were reviewed to refer research methodology to calculate aviation accident costs and safety costs of operators. Safety costs of operators was calculated with literature researches and interview surveys among professionals of each operators in rational range.

본 연구는 유동성 제약이 가족기업과 비가족기업의 투자 지출에 어떠한 영향을 미치는지에 대해 실증분석 하였다. 가족기업은 위험회피성향이 크고 기업의 성과와 명성을 중시하여 대리인 비용이 적을 것으로 예상되어 현금흐름이나 유동성 제약이 투자에 미치는 영향이 작을 것으로 기대 되었다. 유동성 제약이 기업 투자지출에 가족기업과 비가족기업이라는 지배구조 형태 별로 어떻게 달리 영향을 미치는가를 분석하기 위하여, 644 개의 한국거래소 상장기업에 대하여 2000년부터 2010년 까지 기업 재무 테이터를 사용하여 시계열 횡단면 회귀분석을 실시하였다. 분석결과, 가족기업에서 현금흐름변수는 투자지출에 영향을 미치지 못한 반면, 비가족기업에서는 현금흐름 변수가 매우 민감하게 양의 영향을 주고 있는 것으로 나타났다. 현금흐름이 감소하여 유동성 제약에 직면하면 대리인 문제가 큰 비가족기업의 경우 투자는 크게 감소하나, 대리인 문제가 크지 않은 가족기업에서는 투자지출이 유동성 제약에 영향을 받지 않는다는 것을 시사한다. 이러한 연구로부터의 의의는 현금흐름에 대한 투자의 민감도가 기업의 유동성 제약 여부를 나타내는 유용한 지표가 될 수 있다는 점이다.

The choice of big public investment project needs an appropriate feasibility analysis before it is implemented, bemuse a rot wisely chosen one would bring about big and longrun societal costs. But the feasibility analysis for the big public investment project in Korea has been done without linking the economic benefits and environmental damages. Consequently social conflicts arose frequently during and after project implementation, owing to such concerns asincreasing costs and serious ecological damages. The recent social conflict over the Saemangeum Project is a typical case. This reclamation project began in 1991 and finished 60% of the whole process in 1999, when its feasibility was again assessed under the public pressure by the joint assessment team consisting of both citizen's and government's professionals. Even the assessment report by this joint team could not show the convincing results owing to the improper assessment procedure and failure to set proper feasibility criteria. This paper pointed out the limitations of our current procedure of feasibility assessment and identified the concrete problems that atosee during the recent reassessment process of the Saemangeum reclamation project by the joint team. In order to improve the current problem-ridden practices, it is concluded by the policy recommendation for establishing a right feasibility assessment procedure for the public investment projects.

Purpose: Research on attracting foreign direct investment (FDI) plays an important role in helping provinces attract more FDI projects. However, with local competition, FDI enterprises also have to consider their investment. This study evaluates the provincial competitiveness to attract FDI in Thai Nguyen province, a province of Vietnam. In which provincial distribution of competitiveness is measured through nine indicators. Research design, data, and methodology: The study collects data (FDI and the provincial competitiveness index) from 2006 to 2020. The study uses Autoregressive Distributed Lag (ARDL) to text the impact of distribution of competitivenes on foreign direct investment. With time-series, the ARDL is suitable for data analysis. Results: The regression results indicate that the competition index of market entry and informal costs negatively impact attracting FDI into the province; The human resource training quality index has a positive effect on FDI. The results show that FDI enterprises pay much attention to business establishment procedures, hidden costs, and quality of human resources in the province. Conclusions: At the same time, in terms of practice, the results of this study, the authors also offer solutions to help improve the ability to attract FDI into Thai Nguyen province. The significant provincial competitiveness indicators should be taken into account for improvement first.

Although actual business environment is getting difficult and hard, IT companies tend to shy away from of annual investment. Many firms have already reached the 25 percent level. However, the profit and the result of their annual investment needs to be evaluated objectively. IT investment analysis usually proceeds by comparing benefits and costs of an IT investment. Much of the problem derives from the historical treatment of IT as an overhead expense rather than a capital asset. What is most worrying about the current situation is the pressure to take a very short-term view of IT. Therefore, this research aims to analyses and justify the necessity of Visionary IT Investment. For this, it is crucial to identify the factors, which affect positively Visionary IT Investment and understand the role of CIO and explain the result of Visionary IT Investment, which is differed to related business and by different business environment. As a result of this study, the legitimacy of IT Investment is proved through analyzing the business value of not investing and cost-avoidance strategies.
