This study investigated empirically one of the controversial subjects in modern finance, in that there is an optimal level of capital structure for KOSPI-listed firms in the Korean capital market. Given the major theories on the capital structure, such as Myers' pecking order, trade-off, and agency cost ones, this study applied an analysis of covariance models in parametric and non-parametric statistical methods. In particular, two covariates to control for the possible effects of trade-off and agency cost, were employed separately in each corresponding model, while the other proxy for pecking order rationale was adopted in previous research [1] to conduct inter- and intra-industry analyses. Based on the outcomes obtained from the study, it was demonstrated empirically that there are optimal capital structures for firms in the sample industries at the inter-industry level, whereas statistical differences indicating non-existence of an optimal point, were revealed within the industry. Accordingly, these findings suggest a new vision to potential investors that firms in the domestic market may have financial opportunities to increase their value by gradually adjusting the leverage ratios in terms of the intra-industry perspective.

This study focused on the Korean Stock Market so as to recognize the actual Korea-China FTA effect in the firm level. The result are as follows. First, lifting embargo even before the FTA actually took into effect influenced negatively to the firms listed in Korean Stock Market unlike the expectations that effectuation could influence positively to Korean economy. Secondly, the industries that China has attracted more foreign investors than Korea have shown declining returns as they positioned comparative disadvantages in Korea. In this regard, foreign shares delivered signaling effects to domestic investors in Korea. Thirdly, information for effectuation(embargo lifting) has reflected in the stock prices immediately as it leaked in the industries expecting the negative impact, while investors showed the tenancy to retain the action until the FTA actually took into effect in the industries expecting the positive impact.

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.

본 논문은 매출액대비연구개발비비중과 배당성향이라는 두 지표를 사용하여 IPO 전후 기업 경영의 변화를 관측하고, 이 같은 변화가 장기적인 기업 발전을 위한 창업자의 지배권 보장이라는 차등의결권 주식 발행의 필요성을 입증하는지 검토한다. 매출액대비연구개발비와 배당성향은 각각 장기적인 목적과 단기적 목적의 현금흐름 사용의 대표적 지표로서, 두 지표는 현금흐름의 처분에 대한 주주의 압력을 간접적으로 측정하는 지표이다. 두 지표가 IPO를 전후하여 크게 차이를 보이며, 또 그 차이가 단기적 이익보다 장기적 성과를 중시하는 방향으로 나타난다면 장기적 기업 가치 제고를 위해 차등의결권의 유용성을 방증할 수 있으나, 반대의 경우에는 차등의결권 도입의 실증적 근거가 미약하다고 할 수 있다. 본 논문의 분석 결과는 다음과 같다. 첫째, 2000년부터 2016년까지 유가증권시장과 코스닥시장, 코넥스시장에 상장한 기업 중 IPO 전후 3년 간, 즉 t-3년 ~ t+3년에 각각 연구개발비비중과 배당성향을 공시하고 있는 278개 기업과 37개 기업을 조사한 결과, 매출액대비연구개발비 비중이 IPO 이후 반드시 감소하였다고 판단할 수 없었다. 둘째, 배당성향은 일관되게 IPO 이전 수준이 IPO 이후 수준보다 높았다. 이 같은 결과는 기업의 장기적 발전을 위하여 창업자의 지배권을 보장하기 위해 차등의결권이 필요하다는 주장의 실증적 근거가 명확하지 않음을 의미한다. 단기적 시각의 주주에 대항하여 현금흐름과 지배권이 분리된 주식을 발행할 필요가 있다는 주장보다는 차등의결권이 지배주주의 경영권 영속화의 수단으로 활용될 수 있다는 비판이 보다 설득력이 있을 수 있다.

Utilizing intra-day volume weighted average price (VWAP) based on 1 minute return data of stocks traded on the Korean Stock Exchange, this paper examines and analyzes abnormal returns in reaction to patent listing disclosures as well as the cumulative abnormal returns, traded volumes, the interaction of VWAP spreads, the reaction of volumes, the reaction of VWAP spreads and the realized returns obtained from trading using an event driven arbitrage strategy. The results of the aforementioned research topics are follows. First, our analysis suggests that on average, 0.92% positive cumulative returns arise 1 minute after the patent listing disclosure announcement with high statistical significance, thereby reconfirming that the Korean stock market is a semi-strong form of the efficient market. Employing 3 separate panel tests differentiated by the size factor, we find that the abnormal returns of small sized stocks were less than the returns of medium sized stocks, which goes to support recent research findings suggesting that the size premium is no longer existent in the Korean stock market. Secondly, we show that among the event driven type strategies, the most outstanding realized returns are from the market making strategies. Furthermore, placing market order trades only at the bid or ask price resulted in negative returns. This implies that strategies utilizing a combination of market orders and limit orders, order cancelations ratios and order flows can enhance realized returns.

Given the ongoing debate in many aspects of finance, more attention may need to focus on corporate R&D expenditures. This study empirically tests financial determinants of R&D expenditures for NYSE-listed and KOSPI-listed firms. Three major hypotheses were postulated to test for corporate R&D outlay. First, proposed variables such as one-year lagged R&D expenditures, market value based leverage, profitability and cash holdings showed significant influence on corporate R&D costs for the sample firms. Moreover, financial factors inclusive of squared one-year lagged R&D expenditures, the interaction effect between one-lagged R&D expenditures and high-growth firm, non-debt tax shield, Tobin's q and a dummy variable to explain differences in accounting treatment between the U.S. and Korea, revealed significant differences between the two samples. Finally, in the conditional quantile regression (CQR) analysis for the R&D-related variables in relation to corporate growth rate, it was found that the NYSE-listed firms had a statistically significant linkage between growth potential and one-year lagged R&D expenditures at lower quantile levels. This study may shed new light on identifying financial factors affecting differences between the U.S. market (as an advanced market) and the Korean market (as an emerging market) regarding the optimal level of R&D investments for shareholders.

This study examined the effects of the firm characteristics of the manufacturing industry on the female employment ratio. Three hypotheses regarding female employment ratio, were tested for 5,729 firms that could use financial data among the firms listed on the KOSPI from 2011 to 2019, in terms firm size, listing period, and foreign ownership. Follwing the analyses, three hypotheses were mostly adopted. It was found that as the size firm and foreign ownership ratio increased, the female employment ratio increased in the number of regular and permanent contract employees, fixed-term employees, and total employees. As for the listing period, the higher the value, the lower the female employment ratio in the number of regular and permanent contract employees, fixed-term employees, and total employees. These research results may be used as basic data for gender equal employment policies such as Affirmative Atcion for Gender Equal Employment.

This study analyzed the accounting conservatism of companies listed on KONEX. The analysis of the existing accounting conservatism presents the analysis results for the KOSPI market or the KOSDAQ market. However, in July 2013, Korea opened a new publicly traded market called KONEX, which has been continuously operated to increase the possibility of SMEs' financing. However, research on KONEX has not been conducted relatively actively, and the current prior research is also focused on earnings management. This study differs from previous studies in that it analyzes accounting conservatism, which is one of the accounting policies. For this purpose, the period from 2014 to 2020 was set as the analysis period, and empirical analysis was conducted using the asymmetric timeliness models, Ball and Shivakumar (2005) and Basu (1997). As a result of the analysis, conditional conservatism was also confirmed in the KONEX market. That is, it was confirmed that the timeliness of the bad news was higher than the good news. Second, no significant difference was found in the results of analyzing whether there is a difference in the conservatism of KONEX companies according to the size of the auditor. In other words, it was confirmed that the size of the auditor in the KONEX market is not a significant variable. This study expanded the existing research in that it analyzed accounting policies targeting the KONEX market.

This study investigates the sensitivity reflected in the accounting earnings differs according to the difference in the characteristics of accounting information such as profit and loss for the same market information. For this, market information and accounting data were analyzed for 11,462 non-financial listed companies listed on the KOSPI and KOSDAQ markets from 2012 to 2020 by using Basu's measurement of conditional conservatism and Ball and Shivakumar's measurement of conservatism. Accounting earnings sensitivity was analyzed according to the combination of information. As a result of the study, it was confirmed that both earnings and losses corporates recognize losses with delay, while losses are recognized quickly by loss corporates and delayed recognition by earnings companies. It was confirmed that more strict conservatism was applied to the losses corporates compared to the earnings corporates by delaying the recognition of earnings while the early recognition of the losses. It provides empirical data on the causality between the asymmetric timeliness and the combined effect of market information and accounting information by verifying that the losses corporates responds sensitively to market information while the earnings corporates does not react sensitively to the market information.
