우리나라의 공적개발원조는 큰 성장을 보이고 있으며, 특히 직업훈련학교에 대한 지원은 그 효익이 직접적이고 단기적으로 발생되게 되어서 수원국에 큰 효익을 안겨준 것으로 평가되고 있다. 그러나 공적개발원조에 대한 경제적 성과를 측정할 수 있는 모형이 없어서 단편적인 성과 측정에 머무르고 있다. 본 연구의 목적은 개도국 직업훈련학교에 대한 공적개발원조 시 적용가능한 경제적 성과측정모형을 개발하고자 하는 것이며, 이를 위하여 재무정보를 중심으로 하는 ROI모형을 설정하고 여기에 비재무정보를 중심으로 하는 BSC를 접목하였다. 직업훈련학교는 그 효익의 대상이 명확하고 효익이 교육생의 졸업과 동시에 발생되는 특징이 있으므로, 비재무정보 보다는 재무정보 중심으로 모형을 구셩하는 것이 보다 목적적합하다고 사료된다.

The Purpose of this study is to test empirically the determinants of capital structure of the Korea Listed Firms. In order to accomplish the purpose of this study, both literature survey and empirical test have been made. For the empirical test, agency and asymmetric information factors as well as traditional ones have been throughly reviewed. Traditional factors tested in this study include firm-size, collateral value of the assets, business risk, tax, non-debt tax shields, and industry effects. Agency and asymmetric information factors include growth opportunities, the percentage of outstanding equity held by inside stockholders, and the number of inside stockholders. From the results of the cross-sectional regression analysis, the adjusted R-square is 1931%, and the overall F-value indicates significance. For the analysis period, the signs of the variables except business risk are as predicted. Firm-size, collateral value of the assets, and business risk significant at the.01-.05 level. In order to determine the influence of industry factors on the financial leverage, a total of 8 dummy variables are added to the regression model. The adjusted R-square inclosed by 4.2% for the first analysis period(1983-1985) and 6% for the second analysis period(1986-1987). This suggests that industry factors are significant in explaining the variations in financial leverage across firms. In order to pursue the influence of agency and asymmetric information factors on the financial leverage, again the cross-sectional regression analysis is done for the middle size firms gruop(n=40). The adjusted R-square increased by 9.8% for the first analysis period(1983-1985) and 6.1% for the total analysis period(1983-1987), and all the signs was as predicted. But both the variables except the number of inside stockholders was not significant.

Purpose - The National Agricultural Cooperative Federation of Korea and National Fisheries Cooperative Federation of Korea have prosecuted both financial and retail businesses. As cooperatives are public institutions and receive government support, their sound management is required by the Financial Supervisory Service in Korea. This is mainly managed by CAEL, which is changed by CAMEL. However, NFFC's business section, managing the finance and retail businesses, is unified and evaluated; the CAEL model has an insufficient classification to evaluate the retail industry. First, there is discrimination power as regards CAEL. Although the retail business sector union can receive a higher rating on a CAEL model, defaults have often been reported. Therefore, a default prediction model is needed to support a CAEL model. As we have the default prediction model using a subdivision of indexes and statistical methods, it can be useful to have a prevention function through the estimation of the retail sector's default probability. Second, separating the difference between the finance and retail business sectors is necessary. Their businesses have different characteristics. Based on various management indexes that have been systematically managed by the National Fisheries Cooperative Federation of Korea, our model predicts retail default, and is better than the CAEL model in its failure prediction because it has various discriminative financial ratios reflecting the retail industry situation. Research design, data, and methodology - The model to predict retail default was presented using logistic analysis. To develop the predictive model, we use the retail financial statements of the NFCF. We consider 93 unions each year from 2006 to 2012 to select confident management indexes. We also adapted the statistical power analysis that is a t-test, logit analysis, AR (accuracy ratio), and AUROC (Area Under Receiver Operating Characteristic) analysis. Finally, through the multivariate logistic model, we show that it is excellent in its discrimination power and higher in its hit ratio for default prediction. We also evaluate its usefulness. Results - The statistical power analysis using the AR (AUROC) method on the short term model shows that the logistic model has excellent discrimination power, with 84.6%. Further, it is higher in its hit ratio for failure (prediction) of total model, at 94%, indicating that it is temporally stable and useful for evaluating the management status of retail institutions. Conclusions - This model is useful for evaluating the management status of retail union institutions. First, subdividing CAEL evaluation is required. The existing CAEL evaluation is underdeveloped, and discrimination power falls. Second, efforts to develop a varied and rational management index are continuously required. An index reflecting retail industry characteristics needs to be developed. However, extending this study will need the following. First, it will require a complementary default model reflecting size differences. Second, in the case of small and medium retail, it will need non-financial information. Therefore, it will be a hybrid default model reflecting financial and non-financial information.

Previous literature in financial economics documents the existence of a liquidity premium in expected returns, measured by the bid-ask spread. This study provides a more comprehensive test of the egect of liquidity on common stock returns by including trading volume as an additional liquidity measure. we find that trading volume is a relevant measure of liquidity, and affects expected returns even aher controlling for the effects of systematic risk, firm size, and the relative bid-ask spread. We also find that trading volume complements the bid-ask spread as a liquidity measure, and provides additional information about the liquidity premium. The liquidity effect emerges in non-January months as a volume effect, in addition to the spread effect in January documented by Eleswarapu and Reinganum(1993).

The purpose of this study is to analyze the effects of the BSCs of 642 firms excluding the financial and insurance companies listed on KOSPI. The analysis of financial performance through analysis of major financial ratios between BSC and non-BSC firms is compared with the input of human and material resources for business growth. We will promote the spread of BSC and examine the areas differentiated performance improvement. The analytical categories are manufacturing, service, wholesale and retail, and information and communications, which are 2,136 business years out of 2,378 final analytical samples. The results of the analysis are as follows. As a result of the analysis, among the four industries analyzed, the industries that showed the best performance were manufacturing. In the case of service industry, growth and activity were lower than those of non-adoption (NA) companies, but the operating margin was significantly different from manufacturing. However, market value was higher than that of NA companies, and R&D expenditures and advertising expenses were significantly higher than NA firms. On the other hand, there was no significant difference in profitability between the BSC and NA firms, but the market value was very significant. EPS is 5.22 times, BPS is 5.64 times, PBR is 1.3 times, and EVA is 35 times higher. In addition, R&D expenditure and advertising expenditure are more than twice as high as those of NA. In the case of the service industry, there is no significant difference in the growth performance from the NA firms. Activity indicators, BSC introduced companies are three times lower than both the total assets turnover and the capital turnover rate. The operating profit margin was high at 45.8% for introduced companies and 37.2% for non-introduced companies. In market value analysis, only BPS was 1.68 times higher. On the other hand, investment in welfare expenses is 0.2% of total assets, which is relatively low compared to NA firms. However, research and development expenses and advertising expenses are 2.1% and 1.02% of total assets, respectively, but they are relatively lower than those of NA firms. Unlike the manufacturing and service industries, wholesale and retail trade was significantly higher than the NA firms in terms of sales growth and total assets growth rate. In terms of market value, EPS and BPS were significantly higher, but the benefits, R&D expenditures, and advertising expenses were lower than those of NA firms. The information and communication industry showed lower level of performance than the NA firms in all indicators except cash liquidity, BPS, and EVA.

본 연구는 전 세계적으로 증가하고 있는 외국인직접투자가 현지국의 에너지 집약도에 어떠한 영향을 미치는가에 대한 분석을 목적으로 한다. 국가별로 에너지 소비와 그들이 보유한 흡수능력에 차이가 존재함에 따라 OECD와 Non-OECD 두 국가집단으로 나누어 비교하였으며, 세 가지 흡수능력인 인적자본, 금융시스템, 인프라를 중심으로 1990년부터 2011년까지의 패널데이터를 이용하여 분석하였다. 실증분석 결과에 따르면 OECD 국가의 경우 인적자본과 금융시스템이, Non-OECD 국가의 경우 인적자본과 인프라가 흡수능력으로써 FDI와 보완적인 효과를 내어 현지국의 에너지소비를 감소시킬 수 있었다. 이러한 차이가 발생하는 이유는 현지국이 보유한 흡수능력의 수준에 따라 그 발휘력 모두 다르기 때문이다. 이러한 차이를 토대로 두 국가집단들이 각각 지속가능한 경제성장을 위하여 어떠한 외국인 직접투자를 유치하여야 하는지 논의하였다.

The midst competition makes a brand all together with its offering products and services is becoming a crucial element for company existence. This requires direct involvement from internal organizational to develop effective strategic branding. According to Asosiasi Penyelenggara Internet Indonesia (APJII), Indonesia's internet penetration is among the highest in Asia. The purpose of this research is to improve the strategic role of brand orientation within Internet Service Provider (ISP) for maximizing return on the company's financial and non-financial benefits by proposing organization change readiness variable. The data collection is taken using an online survey with a non-parametric sampling method and collected 68 qualified respondents for data analysis using SEM-PLS (Structural Equation Modeling with Partial Least Square). The result indicates partial hypotheses on the constructed model between variables brand orientation, brand commitment, and internal brand equity is acceptable. Another finding is stated hypotheses on organization change readiness as moderation is not accepted and means there is no significance to the constructed model. The main conclusion resumes associative human memory can shape up organization change readiness inside internal toward then brand. Relevant cues generate information received in the human brain then will create common associative and becoming social identity on internal brand equity.
