This study examines the determinants of the long-run stock price performance of the firms that granted stock options between 1997 and 2002. We divide the sample into the firms run by the owner and those run by the professional manager. If the primary reason for granting stock options is reduction of the agency costs between the manager and shareholders, the effect of stock options is likely to be more pronounced in the firms run by the professional manager. We find that the long-run abnormal returns of the firms run by the professional manager are negatively associated with the shareholdings by the manager and the book-to-market value and are positively associated with the earnings growth and the size of the outstanding stock options. In contrast, the long-run abnormal returns of the firms run by the owner are negatively associated with the cash flows rate and the sales growth rate and are positively associated with the firm size. This is consistent with the argument that the agency costs arising from the conflicts between the manager and shareholders are an important determinant of the post-stock option granting long-run stock price performance only in the firms run by the professional manager. The results also suggest that stock options in the firms run by the owner are likely to be used for the purposes such as additional compensation, a signaling device, a means that reduce the agency costs within firms.

The purpose of this paper is to explore the relationship between industrial regulations and the R&D activities of firms by analysing the case of manufacturing enterprises in Korea. The sample is gathered from the 2012 Korean Innovation Survey data of Korean Institute of Science & Technology Evaluation and Planning and merged with Korean Regulation Index data of Korean Institute of Public Administration. The Ordinary Least Square (OLS) as well as 2 Stage Least Square (2SLS) regression results show that the impact of the level of the manufacturing field's regulation on firms' R&D activities or inputs may be both positive and negative, depending on the size of the firms. The analysis results suggest that regulatory policy makers need to formulate and implement R&D programs that consider the different effects of industrial regulations on large enterprises or Small and Medium sized Enterprises (SMEs).

It is difficult to distinguish a lung cancer from a pulmonary tuberculoma or other benign nodule. It is even more difficult to identify the type of lesion if the mass shows no change in size or demonstrates slow growth. Only a pathological confirmation can possibly reveal the nature of the lesion. A 61-year-old-woman was referred for a solitary pulmonary nodule. The nodule showed no change in size for the first two years and continued to grow slowly. Pathological and immunological analyses were conducted for confirmation of the nodule. The nodule was identified as a well-differentiated primary pulmonary adenocarcinoma. An LULobectomy was performed, and the post surgical stage of the nodule was IIIA (T2N2M0). Even though there are few risk factors, there is still the possibility of a malignancy in cases of non-growing or slow growing solitary pulmonary nodules. Therefore, pathological confirmation is encouraged to obtain a firm diagnosis.

The Korean economy has undergone growth based on manufacturing end products. The Korean government aims to advance industry by strengthening the materials and components industry, which is attracting more attention in terms of maintaining the competitiveness of existing key industries, and fostering new industries required in the era of the Fourth Industrial Revolution. Despite this importance, there is insufficient related research on the efficient R&D of the materials and components industry. This study analyzed the R&D efficiency. In addition, exploratory research was conducted on the impact of corporate size and type of cooperation on R&D efficiency. Output variables were set to reflect economic performance and the empirical analysis revealed that overall R&D efficiency is low. Small firms were found to perform better than large firms in terms of firm-size, and the efficiency of business-university-research cooperation is worse than other types of cooperation. This study is exploratory research considering the materials and components industry, and the results provide implications for research institutions and regarding types of cooperation. This is expected to help develop polices for qualitative growth and R&D strategies for investment and allocation.

The introduction and operation of compensation committee can affect managers' incentive-compensation system. In this context, The purpose of this paper examines whether managers' pay-performance sensitivity is affected by the quality of the compensation committee(compensation committee size, the proportion of outside directors on the compensation committee, the proportion of directors with 2 or more non additional board seats on the compensation committee) To test this hypothesis, we use a sample of 260 firm-year observations between 2001-2013. The results are as follows. Firstly, we find that no significant relevance between the compensation committee size and pay-performance sensitivity. But the proportion of outside directors on the compensation committee and the proportion of directors with 2 or more non additional board seats on the compensation committee is positively associated with both pay-earnings based performance sensitivity and pay-stock based performance sensitivity. Secondly, we find that the integration quality of the compensation committee is positively associated with both pay-earnings based performance sensitivity and pay-stock based performance sensitivity. Overall, our analysis suggests that compensation committee are important mechanism in the design of efficient incentive-compensation system.

Input ratio of electricity to other production inputs in the Korean manufacturing sector has been higher than for the other OECD countries. In addition, electricity prices in Korea has been relatively lower than the average of OECD countries. Moreover, electricity sector is responsible for most CO2 emissions in Korea as coal and natural gas account 41.9% and 26.8% of electricity production as of 2018. Therefore, it looks inevitable to raise the electricity tariff for the manufacturing sector in Korea, but there is a concern that increase in the electricity tariff might affect small and medium enterprises (SMEs) more than large firms. This study estimates electricity demand's price and output elasticities for large firms and SMEs in steel industry by employing a time varying parameter model (Kalman filter). The analysis shows that changes in output levels regardless of firms' size affect electricity demands more significantly than do changes in electricity prices. Second, large firms have higher variances for both price and output elasticities of electricity demand. Third, large firms have higher price elasticity but lower output elasticity of electricity demand relative to SMEs. Policy implications are suggested in association with how to reduce electricity demands in the energy-intensive industry.

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.

Using an event study, this paper investigates stock price reactions on Korean listed firms' convertible bond (CB) issue announcements over the sample period of January 2000 to November 2007. This study finds that on the Korean Security market, the CB issue announcements are associated with an increase in shareholder wealth on the announcement date. An information leakage by insider traders is also observable at preannouncement dates. Unlike the prior studies that indicate a prevailing negative effect on the announcements, this paper shows that domestic CB issue announcements as well as offshore ones yield a positive impact on the stock prices. This presents that in terms of stock price reactions to the CB issue announcements, the two CB issue markets show the positively same effects on shareholder wealth for the post-2000 period. For its drivers, this paper suggests that on the Korean market, firm size have negative relationship with the increase in the wealth incurred by the announcements. By contrast, an issue to maturity, a growth opportunity, and a relative issue size make a positive impact on it.

The purpose of this study is to investigate the relationship between supply chain sustainability antecedent, supply chain competence, and supply chain sustainability. The relationship between supply chain sustainability antecedence factor and supply chain competence, supply chain competence and supply chain sustainability and to identify the differences between sustainability antecedence factors, capacity and sustainability depending on the size of the firm. To accomplish this, each research hypothesis was established and the results are as follows. First, compliance with environmental regulations, NGO response activities, CSR activities, and trade fairness were found to have a significant positive impact on manufacturing agility, environmental management, and social capital. And manufacturing agility, environmental management, and social capital has been confirmed that most of the economic, environmental and social sustainability have a significant positive influence. In addition, it has been confirmed that there are differences in the factors of supply chain sustainability, capacity, and sustainability depending on the size of the company. According to the results of the study, environmental regulation compliance, NGO response activities, CSR activities, and fairness factors selected as the leading factors of supply chain sustainability play a role as fundamental prerequisites for supply chain competence to achieve sustainability. Manufacturing agility, environmental management, and the formation of social capital have confirmed that they can raise the level of economic, environmental and social sustainability. Therefore, it was confirmed that the enhancement of supply chain sustainability precedence factors can lead to enhancement of supply chain competence, and furthermore, sustainability of supply chain. Compared with large corporations, SMEs' supply chain sustainability precedence factor, capacity and sustainability should be further improved.

Recently, the aging of SME managers has emerged as a major issue in business succession. The smooth succession of small and medium-sized enterprises (SMEs), which are the industrial base of Korea, is becoming an important issue for enhancing the vitality of the national economy, such as job creation, beyond mere discussion of inheritance. At this point, this study conducted an empirical analysis on the factors affecting corporate succession intention. As independent variables, corporate Capability consisting of employee competency, marketing competency, and digital competency, human factors such as managers, successors, and third-party stakeholders, and institutional factors such as legislation, taxation, and trust were set. In addition, the effect of adjusting the sales scale was verified. To this end, a survey was conducted targeting representatives who are currently running small and medium-sized enterprises (SMEs). The total number of valid questionnaires was 315. Based on this, an empirical analysis was conducted using the hierarchical regression method. The results of the empirical analysis are as follows. First, marketing competency and digital competency, managerial competency and successor competency, taxation and trust had a significant positive (+) effect on corporate succession intention. However, a significant influence relationship between the third stakeholder, employee competency, and corporate succession intention was not tested. Among the factors that have a significant impact, the size of the influence was in the order of taxation, successor competency, executive competency, trust, marketing competency, and digital competency. Second, the size of sales was found to moderate the relationship between the variables that had a significant effect on corporate succession intention, that is, management competency, successor competency, marketing competency, digital competency, taxation and trust, and corporate succession intention. Based on these research results, academic, practical, and institutional implications for smooth business succession are presented.
