본 논문에서는 차입원가의 회계처리에 대한 기업회계와 세무회계의 차이를 줄이는 방안을 제시하였다. 일반 기업회계기준의 차입원가자본화 회계처리는 KIFRS와 일치시키는 방향으로 개정할 필요가 있다. 적어도 비상장기업에 대해서는 법인세법에서 건설자금이자의 손금불산입 규정을 적용하지 않아도 되도록 허용하는 것이 바람직하다. 세무회계상 자본화대상자산의 범위를 기업회계와 일치시키는 방안을 검토할 필요가 있다.

배출권 이월 및 차입은 감축기술개발투자에 영향을 미칠 수 있다. 배출권거래제하에서 이월 및 차입이 허용되면 감축비용과 배출권 가격에 따라 배출권거래제 참여기업들은 현재의 감축을 미래로 또는 미래의 감축을 현재로 선택할 수 있기 때문에 배출권 이월 및 차입은 감축기술개발에 대한 대체재적인 역할을 한다. 따라서 배출권 이월 및 차입과 같은 간접감축이행수단을 허용하는 경우에는 직접감축이행수단인 감축기술개발투자에 영향을 미친다. 불완전경쟁시장에서 이러한 간접감축조치가 감축기술개발투자에 미치는 영향은 완전경쟁시장하에서와 달라질 수 있다. 왜냐하면 과점시장의 쿠르노 경쟁하에서 감축기술개발투자가 최종소비재시장의 균형에 영향을 미칠 수 있기 때문이다. 분석 결과, 배출권 이월 및 차입으로 인한 감축기술개발투자 유인 수준은 감축비용, 할인계수, 초기무상할당, 감축기술개발투자효과 등에 의존한다.

This study examined which factors influence the parental borrowing for children's college education in the U.S. A double-hurdle model was applied to analyze both the parents’decision to borrow and the amount of borrowing. Parents’income and total costs of college attendance had significant positive effects on both the decision to borrow and the amount borrowed. Students’income, parents’cash and savings had significant negative impacts on the amount borrowed, while home equity and the students’expected future income were significant positive factors. Greater amounts of grants significantly increased the probability of borrowing, but reduced the loan amount. Parents with smaller household size, and those who were college graduates were more likely to borrow. White parents borrowed greater amounts than did their non-White counterparts. The age of the student was a significant negative factor in the probability, as well as the level, of borrowing.

본 연구는 독특한 기업 지배구조 형태가 대리인비용을 완화시켜 차입비용을 감소시킬 수 있는지에 대해 실증 분석하였다. 지배대주주가 존재하는 가족기업은 그렇지 않은 기업에 비해 위험회피 경영과 기업의 성과와 명성 중시 및 기업의 장기 존속 등의 면에서 채권자들과 이해가 일치되어 부채의 대리인비용이 완화될 수 있다고 주장되었다. 본 연구에서 지배 대주주 지분율 및 외국인투자자 지분율 등 기업 지배구조와 차입비용 사이의 관계에 대한 실증 분석결과, 지배대주주 지분율과 외국인투자자 지분율은 차입비용에 대해 2008년 금융위기 이전에는 계수추정치가 유의적이지 못하였으나 2008년 금융위기 이후에는 계수추정치가 유의적으로 나타났다. 2008년 금융위기가 극복된 이후에, 지배대주주 지분율은 차입비용과 음의 유의적인 계수추정치를 보여 기업 지배구조에서 가족 지배대주주의 존재는 차입비용을 감소시키는데 크게 긍정적인 영향을 미치는 것으로 나타났다. 반면, 외국인투자자 지분율은 차입비용과 양의 유의적인 계수추정치를 보여, 오히려 차입비용을 증가시키고 있는 것으로 나타났다. 본 연구를 통해, 지배대주주 지분율이나 외국인투자자 지분율 같은 기업의 지배구조 형태가 기업의 차입비용과 신용위험에 미치는 영향은 체계적이며 계량적으로 유의적으로 나타나고 있으며, 취약한 지배구조는 주주들에게 부정적인 영향을 미칠 뿐만 아니라, 기업의 경제적 가치를 하락시켜 채권자들에게도 불리한 영향을 줄 수 있다는 것이 확인된 것이다.

본 연구는 기업지배구조가 차입비용에 미치는 영향을 외국인 기관투자자의 역할에 초점을 맞추면서 분석하였다. 서로 다른 지배구조에 따른 차입비용에 영향을 보기 위해, 최대주주 지분율 기준으로 소유 집중도가 작은 기업표본, 중간 기업표본, 큰 기업표본으로 분류하여 회귀분석을 실시하였다. 분석결과, 소유 집중도가 중간이나 작은 기업표본에서는 외국인 투자자가 기업 차입비용에 영향을 미치는 것이 확인되지 않았으나, 소유 집중도가 큰 기업표본에서는 외국인 투자자가 기업의 차입비용을 크게 감소시키고 있는 것으로 나타났다. 본 연구의 학술적 시사점으로는, 지배대주주의 지분율이 높아질수록 이해일치가설에 의해 지배대주주는 자신의 사적 이익을 추구하게 되어 대리인 비용이 증가하고 경제적 가치가 하락하여 신용위험과 차입비용 증가로 이어질 수 있다는 것을 보여 준다. 실무적 시사점으로는, 외국인 투자자는 소유 집중도가 큰 기업에서 지배 대주주를 잘 견제 감시하고 경영의 외부감시 주체로서 경영 의사결정 효율화에 중요한 역할을 담당할 수 있다는 것을 보여준다.

Background: One goal of the End tuberculosis (TB) Strategy is to see no TB-affected households experiencing catastrophic costs. Therefore, it is crucial for TB-elimination programs to identify catastrophic costs and their main drivers in order to establish appropriate health and social measures. This study aimed to measure the percent of catastrophic costs experienced by Egyptian TB patients and to identify its determinants. Methods: We conducted a prospective cohort study with 151 Egyptian TB patients recruited from two chest dispensaries from the Cairo governate from May 2019 to May 2020. We used a validated World Health Organization TB patient-cost tool to collect data on patients' demographic information, household income, and direct and indirect expense of seeking TB treatment. We considered catastrophic TB costs to be total costs exceeding 20% of the household's annual income. Results: Of the patients, 33% experienced catastrophic costs. The highest proportion of the total came in the pre-treatment stage. Being the main breadwinner, experiencing job loss, selling property, and the occurrence of early coronavirus disease 2019 lockdown were independent determinants of the incidence of catastrophic costs. Borrowing money and selling property were the most-often reported coping strategies adopted. Conclusion: Despite the availability of free TB care under the Egyptian National TB Program, nearly a third of the TB patients incurred catastrophic costs. Job loss and being the main breadwinner were among the significant predictors of catastrophic costs. Social protection mechanisms, including cash assistance and insurance coverage, are necessary to achieve the goal of the End TB Strategy.

The study seeks to evaluate the impacts of three types of credit - formal, semi-formal, and informal credits - on the well-being of households in Vietnam's rural areas. Based on data from the Vietnam Household Living Standard Surveys in 2014 and 2016, the research uses the instrumental variable fixed-effect models to estimate the effects of three kinds of credit on household's per capita income and expenditure. There are some significant findings. First, in rural areas, formal credit is the most popular source with stable and cheap borrowing costs. Informal credit is a complement to formal credit to meet urgent needs. Funding agriculture activities is the most commonly cited purpose of borrowing, followed by purchasing assets. The highest misuse rate belongs to the group of loans for agriculture production. Second, the results show that credit helps smoothen consumption rather than generate income for rural households. Three types of credit have insignificant or negative effects on household's per capita income. Formal loans significantly improve total expenditure and spending on healthcare and education. Informal and semi-formal credits show a little influence on consumption. Informal loans have a significantly positive effect on healthcare expenditure. In contrast, having semi-formal loans tends to decrease spending on foods.

Multiperiod portfolio selection problem attracts more and more attentions because it is in accordance with the practical investment decision-making problem. However, the existing literature on this field is almost undertaken by regarding security returns as random variables in the framework of probability theory. Different from these works, we assume that security returns are uncertain variables which may be given by the experts, and take absolute deviation as a risk measure in the framework of uncertainty theory. In this paper, a new multiperiod mean absolute deviation uncertain portfolio selection models is presented by taking transaction costs, borrowing constraints and threshold constraints into account, which an optimal investment policy can be generated to help investors not only achieve an optimal return, but also have a good risk control. Threshold constraints limit the amount of capital to be invested in each stock and prevent very small investments in any stock. Based on uncertain theories, the model is converted to a dynamic optimization problem. Because of the transaction costs, the model is a dynamic optimization problem with path dependence. To solve the new model in general cases, the forward dynamic programming method is presented. In addition, a numerical example is also presented to illustrate the modeling idea and the effectiveness of the designed algorithm.

In this research, schedule optimization is defined as balancing the number of workers while keeping the demand and needs of the project resources, creating the perfect schedule for each activity. Therefore, when one optimizes a schedule, multiple potentials of schedule changes are assessed to get an instant view of changes that avoid any over and under staffing while maximizing productivity levels for the available labor cost. Optimizing the number of workers in the scheduling process is not a simple task since it usually involves many different factors to be considered such as the development of quantity take-offs, cost estimating, scheduling, direct/indirect costs, and borrowing costs in cash flow while each factor affecting the others simultaneously. That is why the optimization process usually requires complex computational simulations/modeling. This research attempts to find an optimal selection of daily maximum workers in a project while considering the impacts of other factors at the same time through OPEN BIM based multiple computer simulations in resource leveling. This paper integrates several different processes such as quantity take-offs, cost estimating, and scheduling processes through computer aided simulations and prediction in generating/comparing different outcomes of each process. To achieve interoperability among different simulation processes, this research utilized data exchanges supported by building SMART-IFC effort in automating the data extraction and retrieval. Numerous computer simulations were run, which included necessary aspects of construction scheduling, to produce sufficient alternatives for a given project.

Uncertain factors in finical markets make the prediction of future returns and risk of asset much difficult. In this paper, a model,assuming the admissible errors on expected returns and risks of assets, assisted in the multiperiod mean variance portfolio selection problem is built. The model considers transaction costs, upper bound on borrowing risk-free asset constraints, cardinality constraints and threshold constraints. Cardinality constraints limit the number of assets to be held in an efficient portfolio. At the same time, threshold constraints limit the amount of capital to be invested in each stock and prevent very small investments in any stock. Because of these limitations, the proposed model is a mix integer dynamic optimization problem with path dependence. The forward dynamic programming method is designed to obtain the optimal portfolio strategy. Finally, to evaluate the model, our result of a meaning example is compared to the terminal wealth under different constraints.
