Recently, Korean economy is boosted by the active introduction of many venture businesses full of entrepreneurship. It has been widely accepted implicitly that success of the venture business originates from unique style of knowledge management. This assumption looks natural when we consider the fact that success of the venture business heavily depends on differentiated intelligent asset or knowledge. However, such implicit belief has never been tested empirically. To fill the research void like this, this paper proposes an empirical derivation of key success factors from the venture businesses listed in KOSDAQ. To add rigor to our results, we performed regression analysis by using the derived key success factors as independent variables, and introducing organization efficiency, job satisfaction, and accomplishment motivation as dependent variables. Regression results showed that our approach is justified from the statistical perspective.

벤처업계와 정부는 우리 경제의 미래를 짊어질 대안은‘역시 벤처뿐’이라는데 의견을 같이하고 있다. 지난해 이헌재 부총리는 석유를 뿌려서라도 벤처산업을 회생시키겠다며 강력한 벤처육성 의지를 표명한 바 있다. 나아가 지난 12월 23일, 정부는 벤처산업 회생을 위한 긴급처방으로‘벤처 활성화 대책’을 발표했다. 대책이 발표된 후 벤처인의 사기가 고조된 것은 물론 코스닥시장이 7개월만에 400선을 돌파하는 등 매우 긍정적인 모습으로 나타나고 있다. 지난 해 발표된 대책은 벤처 생태계 복원을 위한 여러 조건 중 선결과제인 자금 및 세제지원부분에 초점을 맞췄다. 벤처산업은 자금부분 이외에도 시장, 인력 등 생태계의 균형을 이루어야 바람직한 모습으로 활성화될 수 있다. 이번 호 VD이슈는 지난 호‘다시벤처다1-벤처 활성화 대책’에 이어 좀 더 거시적인 관점에 서‘다시벤처다2-바람직한 벤처 생태계 조성’을 주제로 다룬다. 벤처생태계 조성을 위한 필수요소들을 정리하며 바람직한 대안을 강구해 본다.

This study addresses one of the curent issues in modern finance, which investigates financial profile on the levels of the chaebol firms' cash hoardings in the domestic capital market. Iit may be imperative to search for robust and consistent financial determinants of cash holdings as well as identifying any changes or trend of the determinants affecting the corporate cash reserves in the post-era of the global financial turmoil, considering that interest parties at the government and corporate levels, still seem to have a controversy or debate on excess cash savings. Two hypotheses were postulated and empirically tested for the chaebol firms in the study, such as any transitional changes of the relevant factors on cash holdings and unique attributes of financial factors discriminating between the different type of domestic stock markets.

This study examines the relationship between the release of the news and the individual stock returns. Investors utilize a variety of information sources to maximize stock returns when establishing investment strategies. News companies publish their articles based on stock recommendation reports of analysts, enhancing the reliability of the information. Defining release of a stock-recommendation news article as an event, we examine its economic impacts and propose a binary classification model that predicts the stock return 10 days after the event. XGBoost and LightGBM models are applied for the study with accuracy of 75%, 71% respectively. In addition, after categorizing the recommended stocks based on the listed market(KOSPI/KOSDAQ) and market capitalization(Big/Small), this study verifies difference in the accuracy of models across four sub-datasets. Finally, by conducting SHAP(Shapley Additive exPlanations) analysis, we identify the key variables in each model, reinforcing the interpretability of models.

Technology innovation activity plays a pivotal role in constructing the entrance barrier for other firms and making process improvement and new product. and these activities give a profit increase and growth to firms. Thus, technology innovation activity can reduce the default risk of firms. However, technology innovation activity can also increase the firm's default risk because technology innovation activity requires too much investment of the firm's resources and has the uncertainty on success. The purpose of this study is to examine the effect of technology innovation activity on the default risk of firms. This study's sample consists of manufacturing firms listed on the Korea Securities Market and The Kosdaq Market from January 1,2000 to December 31, 2008. This study makes use of R&D intensity as an proxy variable of technology innovation activity. The default probability which proxies the default risk of firms is measured by the Merton's(l974) debt pricing model. The main empirical results are as follows. First, from the empirical results, it is found that technology innovation activity has a negative and significant effect on the default risk of firms independent of the Korea Securities Market and Kosdaq Market. In other words, technology innovation activity reduces the default risk of firms. Second, technology innovation activity reduces the default risk of firms independent of firm size, firm age, and credit score. Third, the results of robust analysis also show that technology innovation activity is the important factor which decreases the default risk of firms. These results imply that a manager must show continuous interest and investment in technology innovation activity of one's firm. And a policymaker also need design an economic policy to promote the technology innovation activity of firms.

This study explores if the higher initial returns and the poorer long-run performance observed in the IPOs markets are associated with the firms offered in the 'hot markets,' and then empirically examines the effect of optimistic investors' sentiment on this phenomenon, particularly in the aspects of both pricing mechanism and the opportunistic behavior of offering firms. We analyzed a total of 432 IPO firms for the years between 2001 and 2005. This analysis finds that the initial returns and long-run under-performances of 'IPOs in the hot market' are significantly higher than those of 'IPOs in the cold market.' This study also finds that the proxy variables for the optimistic investors' sentiment have a positive effect on the initial return and negative effect on the long-run performance. Finally, this research finds no difference of ownership structure, venture capital backed, and financial properties between hot market IPOs and cold market IPOs. R&D expenditure rate and financial qualities of IPOs are higher in the hot market than in the cold market. These results do not support the 'windows of opportunity' hypothesis that low quality firms take advantage of hot market condition for successful IPOs.

This study analyzed and compared the accounting earnings quality after the adoption of K-IFRS, targeting the stock exchange-listed firms (KOSPI, KOSDAQ). The analysis first revealed that KOSPI had higher quality accruals, and better persistence and predictability of the reported earnings and cash flows, compared to KOSDAQ. Second, in both KOSPI and KOSDAQ, the predictability of future cash flow showed that the accounting earnings was better than the cash flows. Third, for the persistence and predictability of earnings associated with the degree of accruals, in KOSPI and KOSDAQ both all, groups with better accruals quality had greater persistence and predictability of earnings, and a better future cash flow predictability of accounting earnings.

According to the growing importance of science and technology policy, investment in research and development (R&D) has been increased. In this context, a patent as one of outcome of firm's systematic R&D investment is the way to hold a dominant position in companies' technology competitiveness and also to protect technology right. This study attempts to find the effects of input resources and intellectual property production activity on company value. It conducted empirical analysis based on 238 KOSDAQ-listed and medium-sized firms. Using the previous research, this study configurated research variables about activity of patent production, company value, and input of resources. Through these variables, it aims to know the effect of input of resources and activity of patent production on company value. First, the result of regression analysis shows that R&D cost has the positive effect on a patent production and sales promotion cost positively affects on the registration of the trademark. Second, the output of regression analysis indicates that a patent has the positive effect on company value but a trademark has not. With regard to the input of resources, R&D cost has the influence on company value but sales promotion cost has not. This study attempts to find the effectiveness of company's intellectual property registration on its value and suggests a way that the systematic R&D investment contributes the growth of company value.

Since 1996 when Kosdaq market was set up, serious doubt has been raised regarding the efficiency of the market. The most important question is whether this market can reflect the real value of the venture company quoted on it. In order to answer this question, this study aimed to evaluate venture companies in Kosdaq market adopting the concept of real option theory. From the results of empirical analysis, we found that in the early 2000, there was serious over-valuation problem. On the contrary, in the recent period of economic recession, under-valuation problem is quite prevalent. We also present our methodology and empirical results confirm the conjecture that option premium outweighs the DCF valor for the newly born and high-technology intensive venture companies. We hope that the empirical results shed some light on the policy prescription to improve the efficiency of Kosdaq market.

This study aims to test the valur relevance of development cost particularly focusing on IT firms of KOSDAQ. Test period is from 2005 to 2007 and the samples are 2,271 year-firms including 1,692 firms that reported development cost in financial statements. The basic test model is a modified Ohlson(1995)'s linear model. The empirical results show that there is the negative relation between stock price and development cost reported as asset. It means that development costs reported as asset is considered as expense in the market. It implies that development activities of KOSDAQ IT firms is not related to market-leading technologies or goods. Otherwise it might reflect the conservative valuation of market on the unstability of KOSDAQ market itself.
