This study examines whether there is any significant relation between executive compensation and future firm performance for the Korean export manufacturing small and medium-sized firms. We sorted the whole sample firms into the sub-groups of 10 deciles by firm size and the KSIC standard. We found the following empirical results. First, Korean export manufacturing small and medium-sized firms typically showed lower or even negative profitability in terms of return on equity and operating profit ratio to sales. Foreign equity ownership is very low with an average of 3.77%. Second, for the firms with higher ratio of excess executive compensation to asset had lower future firm performance. It implies that the typical owner-manager in Korean export manufacturing SMEs earns excess pay, but do not contribute much to firm performance. Third, as for future cumulative abnormal returns for future one- and three-year periods, firms with higher owner-executive pay had lower returns compared with firms with lower pay. So the stock market investors set a lower value on them. Fourth, there is a positive relation between excess executive pay and executive overconfidence, and it implies that owner-CEOs with higher pay may become overconfident, thereby lowering future firm performance somehow.

신용평가제도는 오늘날 그 영향력이 강력해져 사실상 세계자본시장의 문지기역할을 하고 있다. 본 논문에서는 이와 같이 신용평가기관의 중요성과 영향력의 증대와 더불어 이들 평가기관의 활동에 대한 비판과 감시가 커지고 있는 이때에 아직 선진수준에 미치지 못하는 국내신용평가기관들의 현황과 평가체계를 살펴보고 선진국의 신용평가기관들과 비교해 봄으로써 앞으로 나아갈 방향을 모색해보고자 하였다. 국내 신용평가기관들의 현황을 살펴본 결과 신용평가절차에 있어서 기준이 경영상태, 성장성, 그리고 재무구조의 건전성에 있어야 함에도 불구하고 이러한 기본적인 요인들의 영향력은 미미한 반면, 비공개적이고 불투명하며 비경제적인 요인들이 중요한 비중을 차지하고 있었다. 이에 반하여 선진신용평가기관들의 분석결과는 그 신뢰도에 믿음을 가질 수 있고, 대내외적인 공신력을 인정받고 있으며, 평가과정이 매우 주관적이어서 그 내용을 모두 공개하지 않지만, 국내의 신용평가과정보다는 투명성을 인정받고 있다는 것도 사실이다. 따라서 국내신용평가기관들의 나아갈 바를 살펴보면 다음과 같다. 첫째, 비재무적 요인의 평가기준에 대한 인식의 재정립이 요구되고 있다. 장기적인 시각으로 비재무적 요인에 대한 평가기준과 방법에 대한 체계의 정립이 요구되며, 전문적이고 객관적이면서도 뚜렷한 평가기관의 주관이 있는 평가가 이루어져야 할 것이다. 둘째, 신용평가방법과 기준의 강화로 대외적인 공신력을 얻도록 해야 한다. 이를 위한 방안의 하나로 성장성, 수익성, 그리고 안정성 비율 모두를 반영할 수 있는 신용평가모형을 개발하고, 자기자본비율의 대폭적인 상승이나 현금흐름의 양호여부, 경제적 부가가치(EVA), 고정장기적합률의 이행기준의 설정 등에 대한 평가기준의 재정립이 강구되어야 할 것이다.

This study explores an analytical mathematical model designed to estimate the optimal debt ratio of the Korean automobile industry, which has a more significant effect on the national economy than that of other industries, and attempts to estimate the optimal debt ratio based on objective data. The analytical model is based on ROA and ROE which uses the debt ratio as an independent variable and employs ROS, TAT, and NFCL as the related parameters. Regarding the NFCL, the optimal debt ratio is usually defined as the debt ratio that maximizes the ROA and ROE and is calculated using analytical procedures, such as by adding an equation that considers the debt ratio and the linearity relationship to the analytical model. This is because the optimal debt ratio can be calculated reliably by making use of an estimated value within a certain range, which is derived from more than two calculations rather than a single estimation starting from one calculation formula. In this study, for the estimation of the optimal debt ratio, the ROA and ROE are expressed as a quadratic equation with the debt ratio as the independent variable. Using this analysis procedure, the optimal debt ratio obtained using the data from the Korean automobile industry over a sixteen year period, which would optimize the profitability of the Korean automobile industry, was found to be 188% of the debt ratio in the ROA and 213% of the debt ratio in the ROE. This result was obtained by overcoming the problem of the reliability of the estimation value in spite of the limitations of the logical theory of this study, and can be interpreted as meaning that maintaining a debt ratio of 188% to 213% can enhance the profitability and reduce the risks in the Korean automobile industry. Furthermore, this indicates that the existing debt ratio of the Korean automobile industry is lower than the optimal value within the estimated range. Consequently, it is necessary for corporations to change their future debt ratio policies, given that the purpose of debt ratio management is to maintain safety and increase profitability, and to take into account the characteristics of the specific industry.

This paper has investigated the impact of corporate donation expenditure which has recently drawn great attention in Korean society on businessl performance and conducted an empirical analysis on the causal relations. In addition, concurrent effect has been analyzed using cross-sectional data between two variables (corporate donation expenditure and business performance) while sequential effect has been examined using panel data. The result of this study can be summarized as follows: First, corporate donation expenditure had a positive impact on ROA and ROS. However, PER and ROE had no impact on corporate donation expenditure Second, cumulative effcet of corporate cash donation would have a bigger impact on short-term business performance than long-term performance. In the future, The results of this study is expect through cash donations in the social contribution to be more aggressive in carrying out social responsibilities.

Comovement of international stock market prices has been lately a major controversy in the global stock market. This paper explores whether the common trend has really existed among the US, Japan and Korea's stock markets using the econometric techniques such as VAR, VECM as applied. Pair of indices from the exchange market and the over-the-counter market in each country has been tested, and the exchange market only has been turned out that the common trend existed. The dynamic analyses using the Granger causality test, impulse response function, and the forecast error decomposition have followed to show that the US stock market has played some important role in the Korea and Japan's market in the exchange as well as in the OTC market. The results of the paper imply that the more careful investigation with respect to the co-integration may be necessary in the global market integration studies.

This study measures the managerial efficiency of Korea's 14 public enterprises using bootstrap DEA in 2013. In addition, it examines the factors that affect on the bootstrap bias-corrected efficiency using truncated regression analysis. The results and implications of this study are as follows. First, using bootstrap DEA model analysis, the results showed that the mean technical efficiency was 0.3182, the mean pure technical efficiency was 0.4994 and the mean scale efficiency was 0.6585. The main cause of technical inefficiency was due to pure technical inefficiency. Second, rank test between technical efficiency of general DEA model and bootstrap DEA model was no significant difference under CRS and VRS assumption. Third, the main cause of the inefficiency in 11 DMUs among 14 DMUs were mainly due to the pure technology and three DMUs were because of the scale efficiency. Finally, in the truncated regression analysis, cost of labor, profit, sales, return of equity, and the number of employees appeared as factors affecting the scale efficiency at the 10% significance level.

Business performance measurement is used as an important tool to evaluate management performance, control human resources, and implement strategies. It can be measured simply in terms of finance including net profit, return on investment, and return on equity, but this is not sufficient because the performance outside of finance such as internal business process and informatization cannot be examined. Therefore this study defined a KPI(Key Performance Indicators) applicable to local construction companies ranked in the top 30 in construction capability, and also introduced differentiated results from the earlier studies by reflecting more realistic corporate management based on the existing studies and interviews with business experts.

This study investigates the dynamic relationship between KOSPI200 stock index and stock index futures and stock index option markets which is its derived from KOSPI200 stock index. We use 5-minutes rate of return data from 2012. 06 to 2014. 12. To empirical analysis, this study use autocorrelation and cross-correlation analysis as a preliminary analysis and then following Stoll and Whaley(1990) and Chan(1992), the multiple regression is estimated to examine the lead-lag patterns between the stock index and stock index futures and option markets by Newey and West's(1987) Empirical results of our study shows as follows. First, there exist a strong autocorrelation in the KOSPI200 stock index before 10minutes but a very weak autocorrelation in the stock index futures and option markets. Second, there is a strong evidence that stock index future and option markets lead KOSPI200 stock index in the cross-correlation analysis. Third, based on the multiple regression, the stock index futures and option markets lead the stock index prior to 10-15 minutes and weak evidence that the stock index leads the future and option markets. This results show that the market efficient of KOSPI200 stock index market is improved as compared to the early stage of stock index future and option market.

After global economic crisis, China has become one of the two pillars in the global economies and the country contributing to the Korean economy. Nevertheless, the research on Chinese financial market, particularly capital market, is rare to date. This study examined the growth enterprise market that emergedat the Shenzhen stock exchange and made comparative analysis on before and after listing for the Chinese small and medium sized firms and venture firms. The listing requirements at the Chinese growth enterprise market for the technologically innovative venture firms and fast-growing small and medium sized firms with financing purpose were more alleviated than the main board of Shenzhen stock exchange. Moreover, the listing procedures are simplified as well. Accordingly, many Chinese enterprises tend to list and the competition for listing is also intense. In particular, with the 36 initially listed firms at growth enterprise market as the research target, the investigation for the business performance before and after listing reveals that the three indexes including return on common equity, debt ratio and operating profit growth rate dropped dramatically for most all the firms. That is, the profitability and growth for the venture firms and small and medium sized firms listed on the Chinese growth enterprise market decreased rapidly after going public, only the stability improved due to the great financing. Taking a step forward, this phenomenon may result from the exaggerated reporting for the business performance before listing with the purpose of going public by the venture firms and small and medium sized firms. Thus, Chinese Securities Regulatory Commission should strengthen the accounting evaluation standard and regulation for the listing firms before going public. In addition, strict sanctions should be imposed on the firms with fraudulent accounting to establish healthy capital market.

This paper introduces multifractal processes and presents the empirical investigation of the multifractal asset pricing. The multifractal stock price process contains long-tails which focus on Levy-Stable distributions. The process also contains long-dependence, which is the characteristic feature of fractional Brownian motion. Multifractality introduces a new source of heterogeneity through time-varying local reqularity in the price path. This paper investigates multifractality in stock prices. After finding evidence of multifractal scaling, the multifractal spectrum is estimated via the Legendre transform. The distinguishing feature of the multifractal process is multiscaling of the return distribution's moments under time-resealing. More intensive study is required of estimation techniques and inference procedures.
