As technological innovation is becoming important, securing intellectual diversity through the workforce diversity of research organizations is being emphasized. However, views on organizational diversity are still not reaching consensus, and existing evidence have limitations in terms of the empirical approach. Indeed, increasing number of studies which use quantile regression model show that the significance of the relationship between inputs and performance fundamentally differs across different levels of innovation performance.
This study examines the relationship between firms' workforce diversity and innovation performance, where we focus on the impact of gender diversity, age diversity, and education diversity. Methodologically, we conduct quantile regression model analysis to identify the effect of workforce diversity at various levels of innovation performance. The analysis in this study analyses 15,377 small and medium enterprises pooled from a 5-year period (2015-2019).
First, the results of the analysis shows that age diversity in research organizations has a positive relationship with innovation performance. Moreover, the positive effects of age diversity are more pronounced in relatively innovative organizations. This suggests that an organizational structure focused on a particular age group could rather undermine innovation. Organizational structure consisting of researchers of different ages is more positive for innovation performance. Second, we find that the positive effects of education diversity is observed only in organizations with high levels of innovation performance. This suggests that, as the positive effects of organizational diversity vary depending on the level of innovation performance, strategic decisions need to be made based on systematic diagnosis of the organization. Third, the results show that gender diversity is not necessarily related to innovation performance. It is reasonable to understand that the results of this study are due to the failure of the size of female R&D personnel in sample companies to reach the critical level where the effect of gender diversity is expressed.
This study contributes to provide empirical evidence and implications at firm level, which has been relatively insufficient in the Korean context, through empirical research using survey data on small and medium-sized enterprises. In addition, our findings supplement the existing evidence by showing that the relationship between organizational diversity and innovation varies depending on the level of innovation performance through a quantile regression analysis.

Organizational scientists have started a new journey to re-examine the previous findings of behavioral patterns and actions of employees with the lens of new technology and analytic methods. Following this, the current paper introduced and developed a verbal activity detection sensor badge, named Human Matrix for predicting team member influence in the team decision-making process.
Based on the previous studies, this paper hypothesized that team members' expertise level and members' familiarity with others will be positively related to the members' perceived and actual influence on team decision-making outcomes. Further, this paper hypothesized that the duration of members' speaking time is positively related to the members' perceived and actual influence, whereas the frequency of members' short response to other members is negatively related to the members' perceived and actual influence in team decision-making process.
Using a survival simulation experiment, we collected verbal activities (i.e., duration of speaking time and frequency of short responses) using the Human Matrix badges from 35 teams with 142 student members. We found that team members' expertise levels was positively related to the members' actual influence in team decision-making. Also, our results indicated that members' familiarity with others showed a significant positive relationship with the members' perceived influence in team decision-making. Further, we found that the duration of members' speaking time and the frequency of members' short response to other members could predict both the members' perceived and actual influence in the team decision-making process.
This paper developed and validated the verbal sensor technology (i.e., Human Matrix) by testing the member influence in team decision-making from the survival simulation experiment. Our findings demonstrated that the Human Matrix or a sensor technology in general might help organizational scholars to capture real-time interaction patterns for investigating team behaviors. We discuss the implication of our results for the research.

This study analyzed the relationship between the internationalization of Korean manufacturing firms and their productivity and efficiency. Prior studies have examined the effect of internationalization on firm performance or differences in productivity and efficiency between exporting and non-exporting firms. This study aims to empirically analyze whether strengthening internationalization strategies is advantageous for increasing productivity and efficiency.
The sample consists of 3,725 manufacturing firms (firm-year observations) listed on the Korean Composite Stock Price Index (KOSPI) market from 2003 to 2017. We measured internationalization as the ratio of foreign sales to total sales and productivity as net income per employee and added value per employee. This study adopted data envelopment analysis (DEA) to evaluate efficiency in firms' operating activities and calculated technical efficiency and pure technical efficiency using CCR and BCC models. Then we obtain scale efficiency by dividing technical efficiency by pure technical efficiency.
The results of empirical analysis show a positive relationship between internationalization and productivity measured as net income per employee and added value per employee, supporting Hypothesis 1. Operating cash flow and debt ratio, which are control variables included in our empirical model, were estimated to be statistically significant negative. However, both firm size and foreign ownership were estimated to be a significant positive.
In addition, as a result of estimating the relationship between internationalization, technical efficiency, pure technical efficiency, and scale efficiency, it was found that all of them had a statistically significant positive association, thereby supporting Hypothesis 2. The control variables, operating cash flow and debt ratio, were found to have a significant negative effect on technical efficiency and pure technical efficiency. In contrast, the firm size and foreign ownership had significant positive effects. There were some differences in the results of measuring efficiency as scale efficiency. Operating cash flow and firm size had significant negative effects on scale efficiency, but debt ratio and foreign ownership had no significant effect.
Prior studies have presented evidence for differences in productivity and efficiency depending on whether or not they have entered overseas markets. This study expanded previous studies by providing empirical evidence that strengthening a firm's internationalization strategy improves productivity and efficiency.
Domestic firms experienced many strategic changes as they experienced the 1997 Asia financial crisis and the 2008 global financial crisis. Before the crisis, firms sought profits by mass-producing low-priced products based on low wages, but after the crisis, they have made efforts to achieve growth by eliminating inefficiencies. Research has been conducted on productivity and efficiency improvement in response to this situation, and prior studies have analyzed whether domestic firms' overseas expansion increases productivity and efficiency. Prior studies have explored the increase in productivity and efficiency due to exports. However, this study provided empirical evidence that strengthening firm's internationalization strategy is advantageous for increasing productivity and efficiency.
This study has the following limitations. First, this study measured the level of internationalization as the ratio of FSTS, that is, foreign sales to total sales. Most of prior studies use FSTS as a substitute variable for the level of internationalization. To be robust, we can measure the level of internationalization by applying various measurements such as the number of foreign-invested countries and overseas subsidiaries. Second, our sample consisted of manufacturing firms. In the future, it may be possible to analyze whether the relationship between internationalization level, productivity, and efficiency varies from industry to industry.

The business environment of Korean banks is getting worse due to falling net interest margins, a decrease non-interest profits due to stricter financial regulations, and the entry of fin-tech companies with convenience in IT. Changes in the business environment caused by digital innovation are calling for changes in revenue models based on existing banks' branches. In other words, management strategies are needed to increase the efficiency of branches by classifying tasks that can be converted to digital and reorganizing and strengthening the back office's business capabilities in the long term.
This study aims to present academic and practical implications for tasks that should be more focused on sales branches through efficiency analysis by 'Industrial bank of Korea' branches. This study measured efficiency of 543 bank branches from 2017 to 2019 using SFA methodology and investigated the relationship with operating variables by major bank branches.
Few studies have been conducted on the efficiency analysis of individual banks' branches due to the difficulty of collecting and accessing data by bank branches and the lack of prior understanding of internal operational processes.
Therefore, this study first analyzed the efficiency measurement and results of each bank branch.
The results can be summarized as follows:
First, efficiency measurements using SFA, it was found that the average efficiency has been increasing despite the decrease in average operating profit since 2017. If the performance evaluation is simply made by average operating profit per branch, the internal efficiency improvement may not be considered, which can lead to complaints and problems with personnel and performance assessment.
Second, efficiency using SFA was analyzed to have a negative relationship in relation to working hours. These results mean that longer working hours do not increase the efficiency of branch.
Third, efficiency showed a positive relationship between corporate credit and foreign exchange. On the other hand, personal credit work was not at a significant level. These mean that the proportion of individual financial services that take a relatively long time to work can be reduced by online, and the efficiency of branch operations can be increased when focusing on corporate credit and foreign exchange work.

Fashion is no longer just meeting the basic needs of human life, but it is becoming an important medium for expressing individuality, identity, and taste of individuals, and even for expressing a country's culture. Despite the economic downturn, people's interest in fashion and the fashion industry has not diminished, and in many ways it is expanding. According to the data released by the Korea Federation of Textile Industries, the size of the domestic fashion market was 43.187 trillion won in 2016, 42.47 trillion won in 2017, 43.2181 trillion won in 2018, and 41.64 trillion won in 2019. This amount is more than 40 trillion won, including 2018 which is the largest year compared to the past 20 years. The types that make up the fashion industry also vary in casual, sports clothes, suits, and baby clothes, and for the fashion industry to continue to diversify and develop the kinds that meet the needs of the times, it must be accompanied by steady efforts of domestic fashion companies.
In the long run, in order for the government to create the necessary policies related to the fashion industry or seek ways of innovation in the company itself, it must be preceded by analyzing the cost inefficiency of the company and identifying the detailed causes of inefficiency. In addition, the analysis of inefficiency should be preceded by the major companies leading the fashion industry, and efforts to improve the efficiency of the major companies can be actively used as examples of small companies. Therefore, this study analyzed the efficiency of 19 KOSPI and KOSDAQ listed companies, which represent the Korean fashion industry. It was targeted for four years from 2016 to 2019, and aims to measure the directional cost efficiency using the directional distance function using the Data Environment Analysis (DEA). It also analyzes the association between measured cost efficiency and value added, and further decomposes the measured cost efficiency into technology efficiency and allocation efficiency.
As a result of measuring cost efficiency, the overall average cost efficiency of 19 entities over the period 2016-1919 was 0.540, with significant cost inefficiency for each entity. Looking at the overall average by year, 2016 was 0.577 and 2017 and 2018 seemed to improve gradually as a result of 0.513, 0.514, respectively, but cost efficiency rose again to 0.556 in 2019, still requiring steady efforts to narrow the gap and the figure of cost inefficiency of companies.
In addition, this study analyzed the association with the average cost-effectiveness of 2016-2019 by ranking 19 companies in the order of high average added value for the four years of 2016-2019. As a result, high added value does not necessarily mean good cost efficiency. It can be seen that companies with very high added value are also operating with very low efficiency apart from added value. As a result, companies need to focus not only on increasing value added, but on improving inefficiency, which is prevalent in companies that can be seen as visible side effects.
In this work, we analyze the causes of this inefficiency improvement and decompose the measured cost efficiency into technology efficiency and allocation efficiency using directional functions to present implications. As a result, it has been shown that the main cause of inefficiency lies in technology inefficiency. As a result of this study, measures should be actively sought to reduce inefficiency prevalent in fashion companies, such as innovation in organizational culture, efficient input of resources, and effective government policies.

Counterproductive work behaviors(CWB) are behaviors by employees intended to harm their organization or organization members, such as theft, sabotage, interpersonal aggression, work slowdowns, wasting time and/or materials, and spreading rumors. This research CWB are conceptualized workplace deviance as voluntary behavior that violates significant organizational norms and in so doing threatens the well-being of an organization, its members, or both(Bennett & Robinson, 2000; Robinson & Bennett, 1995).
CWB are consist of types of deviance was whether the deviance was directed or targeted at either the organization(organizational deviance) or at members of the organization (interpersonal deviance) and its associated organizational costs necessitates a specific, systematic, theoretically focused program of study into this behavior.
This research investigate to critical antecedents of CWB such as perception of organizational politics(POP). Also perceived corporate social responsibility(CSR) legitimacy mediated between POP and CWB. Finally, we checked job insecurity moderate between POP and CSR legitimacy and verify the moderated mediation effect. POP defined perceived behavior of proves beneficial or harmful to the organization may depend more on how that behavior is perceived rather than reality. The management of influence to obtain ends not sanctioned by the organization or to obtain sanctioned ends through non-sanctioned influence which divided into go along to get ahead and pay/promotion policies.
Based on the literature review, we set the direct effect, mediated effect, moderate effect, and moderated mediation effect of hypotheses. To test whole of hypotheses, total of 315 questionnaires are used for analysis. To protect the common method bias, 2nd times collecting the questionnaires with time lag of three months. The samples are focus on the CSR activities of 15 companies at Gwanju and Choennam area. The results of empirical test conducted process macro(Hayes, 2018) are as follows. First, POP: pay/promotion policies increased both of interpersonal and organizational CWB. Second, POP: pay/promotion policies decreased perceived CSR legitimacy. Third, job insecurity increased both of interpersonal and organizational CWB however decreased perceived CSR legitimacy. Third, perceived CSR legitimacy mediated between POP: pay/promotion policies and both of interpersonal and organizational CWB. Fourth, job insecurity moderate between POP: pay/promotion policies and perceived CSR legitimacy. Finally, conditionally indirect effect reflected moderation of job insecurity and mediation of perceived CSR legitimacy which POP: pay/promotion policies and both of interpersonal and organizational CWB relationship.
Based on the result, we found that POP: pay/promotion policies, job insecurity are determinants of both of interpersonal and organizational CWB. It was found that if an employee perceives the work environment to be political, he or she reports greater levels of CWB, and lower levels of CSR legitimacy. So that means organization use political manipulations of performance pay and promotion appraisal systems to reward favored employees, send messages to employees who have fallen out of favor, and to build paper trails justifying expected terminations and should attempt to reduce politics in the work environment, as employees' perceptions of such activities lead to CWB.
Moreover, perceived CSR legitimacy conducted mediating role of those of relationship and moderating role of job insecurity. If high on job insecurity, POP: pay/promotion policies negative impacts on boost up perceived CSR legitimacy. This results show that if company dedicate CSR activities, they must build up the alignment of mission, vision, value for legitimacy and mitigate of political behavior in the organizations. Also organizations have been downsizing for competitive advantage caused employee feelings of unstable and violating psychological contract concerning the nature and continued existence of their jobs. The efforts of diminish job insecurity thus become important undertakings. it may be that organizations might be able to take steps to prevent job insecurity from occurring CSR legitimacy and CWB.

An Initial Public Offering (IPO) refers to the process of offering shares of a private corporation to the public in a new stock issuance. IPO is one of the most important events in the company's growth, since the company is growing to secure funding from outside through the case. Previous researches have explored the IPO performance of technological ventures, but the case of family business are not well addressed. Although there are many family enterprises controlled by founders or their relatives in domestic enterprises, nevertheless, research topics on family firms are also limited. However, the founders and families control most of firms in Korea, and thus, and thus it is necessary to examine the relationship between the change in ownership of family controlled firm and IPO performance.
Based on agency theory we considered how the value of newly listed stock price of family firm is influenced by family ownership. Also taking into account of family business, we modeled the effects of family share and it's changes on short-term and long-term IPO performance.
With 598 IPO data listed in KOSDAQ, current paper reports the followings. First, in terms of IPO underpricing in the initial stage of listing, family ownership cannot be seen as a factor influencing the IPO underpricing. This implies that IPO underpricing phenomenon occurred is not determined by family ownership but by other factors such as investor demand, favorable market conditions at the time of listing, and a system that protects investors from new listings.
Second, the long-term IPO performance measured with CAR(cumulative excess return) and BHR(cumulative excess buy and holding return) returns over Fama-French four factors model(2010) is much higher for family controlled firm than those of non-family firm. Specifically, the long-term performance of a family firms that maintains sufficient control outperform that of a family company with weakened control or general firms. This means that public offerings issued by family firms, especially who maintain sufficient corporate control, can be a good long-term investment option.
Based on those results, theoretical and practical implications were discussed in terms of productivity. Limitations of current study and future research directions were also described.

ESG activities, which have a significant impact on an firm's sustainability and corporate value, have received much attention from domestic and foreign investors. Due to their importance, a relationship between ESG activities and corporate value has become an interesting research topic. In this study, the focus of sustainability is on inclusion and exclusion of constituents in the KOSPI 200 ESG Index.
In other words, existing studies involving changes in existing indices have focused primarily on indices representing the country's stock market, but this study focuses on ESG indices, which are highly relevant to sustainability in testing the hypotheses of existing studies. The results of this study are as follows.
First, information incorporated into the ESG index is accepted as a positive signal in the short term, and information excluded is recognized negatively. Therefore, in the short term, it was confirmed that the incorporated companies were much higher than the excluded companies in the CAR.
Second, both added and excluded companies saw their stock prices fall after the index change date. In other words, the price pressure hypothesis was supported. Third, the short-term rise in share prices is accompanied by a relatively high excess volume compared to the trading volume in the overall market, and it is also accompanied by a relatively high rate of change in volume relative to other periods. So, the short-term rise in stock prices, the rise in stock prices caused by increasing liquidity, can be interpreted as supporting the liquidity hypothesis.
Fourth, to test the investor awareness hypothesis, this study compares the shadow costs of incorporated and excluded shares with the number of shareholders. Results for incorporated shares show that shadow costs are reduced and that the number of shareholders increases. So, these results are consistent with the investor awareness hypothesis that the event of index additions causes investors to raise their share prices by reducing shadow costs.
Fifth, in a regression analysis to investigate the relationship with variables affecting CAR caused by information on the inclusion of the ESG index, the excess volume and the rate of change in volume, respectively, have a positive(+) effect on the CAR for the shares incorporated. This can be seen as an additional support for the liquidity hypothesis.
In conclusion, information on the inclusion of the KOSPI 200 ESG index has had a positive impact on investors, along with an increase in transaction volume within the event period, leading to a rise in stock prices, but the increase is minimal. This can be interpreted as not being very meaningful information for investors, as opposed to financial performance, such as productivity and profitability.
The differentiation of this study is that information on the inclusion and exclusion of the KOSPI 200 ESG Index is used to test index change effects. This study has a limitation of measuring index change effects as a short-term stock price response, and this study plans to conduct further studies on the long-term performance of stock prices and their relevance to financial performance, such as productivity and profitability.
