This paper examines how firm's investment has been affected by offshoring and financialization in Korea over the period 2000-2014 by using industry-level data collected from World Input Output Database (WIOD) and firm-level data collected from the KIS-Value Database. The findings are summarized as follows. First, offshoring index as expected shows a negative relationship with real investment. This negative impact is stronger in a large firm group. Second, there is a positive relationship between dividend payments and real investment. The positive relationship is greater in a small & medium-sized firm group. Third, the purchase of financial assets and the income generated from financial assets are positively related to real investment. The positive relationship is stronger in the small & medium-sized firm group. The empirical results show that firm size is a factor that effectively affects firm's real investment. This paper suggests that the influence of financialization and offshoring on firm's real investment should be assessed in various contexts rather than in a unilateral context.

Information technology(IT) investment evaluation requires measurements from many perspectives. Except for the case of financial performance, these measurements mostly belong to the qualitative or intangible domain. The problem with IT investment evaluation lies in the fact that it is very difficult to define the qualitative properties against which to measure the performances. This paper addresses the issue of developing the set of performance indices, and defining the structural relationships between them, such that the IT investment evaluation can be done in a systematic, objective and comprehensive manner. We introduce the balanced scorecard strategy map as the backbone reference frame for the generation of performance indices and for the description of the relationships between them. Sample indices for evaluating projects from strategic perspectives are provided with a case example. A step by step follow through of the index generation process has been presented along with the case.

This paper proposes an improved investment pnonty decision method of facilities considering the reliability of distribution networks. The proposed method decides an investment order of the facilities combining, by fuzzy rules, the investment priority decision by KEPCO and that by reliability evaluation indices. The reliability evaluation indices are SAIFI (System Average Interruption Frequency Index) and SAIDI (System Average Interruption Duration Index). The reliability analysis method of distribution networks applied in this paper utilizes the analytic method, where the used reliability data is the historical data of KEPCO. Particularly, we assumed that the failure rate increases as the equipment ages. To verify the performance of the proposed method, we applied it with the planned projects to reinforce the weak electrical facilities in KEPCO in 2004. The evaluation result showed that, under a limited budget, the reliability of KEPCO in the Busan region using the proposed method could be enhanced if used rather than the conventional method typically in place. Therefore, the results verify that the proposed method can be efficiently used in the actual priorities method for investing in the electrical facilities.

The aim of this study is to provide insight into tax avoidance through planning and management, and its investment consequences in financially constrained and unconstrained firms, as well as to empirically examine the interrelationships between the variables studied. Data was extracted from the financial statement analysis of non-financial companies listed on the Pakistan stock exchange (PSX) published by the State Bank of Pakistan, covering ten major manufacturing sectors. KZ index and WW index are used to identify financially constrained and unconstrained firms. Tax avoidance is measured by using GETR and LETR. All the equations are estimated through panel data regression models using common, fixed, and random effects. The empirical investigation of the role of tax avoidance in all firms collectively and constrained and unconstrained firms separately showed that the tax avoidance behavior of these firms is translated into investments by these firms. The study will help policymakers in strategy formulation and implementation related to tax planning and investment decisions in constrained and unconstrained firms to overcome their financial constraints and to optimize their investment decisions for value maximization. This will substantially increase the investment in the country by providing growth opportunities and lowering the tax rates.

본 연구에서는 CGE(Computable General Equilibrium)모형을 이용하여 28개 산업별 R&D투자액의 GDP 파급효과를 추정한 뒤, 그 결과로써 GDP의 R&D투자탄력성을 계산하여 산업별 R&D 투자 우선순위를 제시하였다. 우선순위는 28개 대분류 산업 중 전체 연구 개발투자에서 차지하는 비중이 1% 미만인 16개 산업을 제외한 12개 산업에 대해서만 적용해 보았다. 먼저 GDP의 R&D투자 탄력성에 근거한 우선순위는 제1차 금속제품, 화학제품, 음식료품, 전기 및 전자기기, 수송장비, 금속제품, 정밀기기, 전력 가스 및 수도, 일반기계, 통신 및 방송, 건설, 사회 및 기타 서비스, 부동산 및 사업 서비스 순이었다. GDP의 R&D투자탄력성에 근거한 순위설정은 비교적 우리나라 산업들의 현황을 잘 보여주고 있는 것으로 판단된다. 보조 지표인 2030년 기준 균형 대비 GDP 증가율에 근거한 우선순위 역시 판정기준으로 유사한 결과를 보여주었다. 결국 두 개의 우선순위 기준은 국가과학기술위원회의 R&D예산투자방향 및 기준 설정과 주요 사업별 예산배분 방향에 좋은 판정기준으로 활용될 수 있음을 보여주었다.

In the paper, the system loss sensitivity index that implies the incremental system loss with respect to the change of bus power is derived using optimization technique. The index λ reaches $\infty$ at critical loading point and can be applied to actual power systems for following purposes. 1) Evaluation of system voltage stability 2)Optimal investment of reactive power focused on minimizing system loss and maximizing system voltage stability 3)Optimal re-location of reactive power focused on minimizing system loss and maximizing system voltage stability 4)Optimal load shedding in case of severe system contingency focused on minimizing system loss and maximizing system voltage stability. Case studies for each application have proved their effectiveness.

주가지수 옵션투자는 과학적인 투자기법이며 다양한 지표 및 투자전략이 개발되어 있다. 본 연구의 목적은 현재 까지 시장에 소개된 다양한 옵션투자 기법들을 적용하여 과거 옵션 데이터를 통해 사후 검증하는데 있다. 옵션 데이터는 2001년 9월부터 2007년 1월까지 실제 증권거래소에서 거래되었던 틱 데이터를 기반으로 하고 있으며 비주얼 베이직을 활용하여 옵션 백 테스팅 모델을 제안하였다. 사후 검증은 틱 데이트를 10분봉으로 변형하여 실증분석 하였으며 옵션에 관한 모든 전략을 모델에 적용시킨 만큼 전략의 유용성을 쉽게 알아 볼 수 있다. 옵션투자는 레버리지가 높아 높은 위험, 높은 이익 구조를 가치는 만큼 시장상황에 맞게 옵션전략을 구사한다면 낮은 위험으로 안정적 수익을 추구할 수 있다.

This paper examines how human capital and other economic variables, such as private investment, economic growth, government investment, inflation, and unemployment influence inequality in Indonesia's provinces. We apply panel data model with fixed effect estimation for the data of 34 provinces from the period 2013 to 2019. We develop a new index for human capital using the education index approach. The results show that human capital has a negative and significant effect on income inequality. An increase in human capital is related to an increase in knowledge and competence due to the longer average school year and expectations of the school year. Human capital has increased the possibility of a person being accepted into the job market and earning a higher income; hence, it lowers income inequality. We also find that inflation leads to a higher gap of income distribution. A further implication of this situation is that the rise in inflation causes an increase in low-income people, and as a consequence, makes their lives worse off. This paper will be beneficial for policy-makers for whom human capital, which is measured using an education index, is an important factor that significantly affects income inequality, in addition to other economic factors.
