본 연구는 저축은행의 소유집중도와 사업다각화 간의 관계를 분석하고자 함이 목적이다. 패널데이터를 이용하여 저축은행의 소유집중도와 사업다각화의 관계를 분석한 것은 기존연구와의 차별성이라 할 수 있다. 분석기간은 2014년부터 2018년까지이며, 79개 저축은행을 대상으로 반기 재무자료를 이용하였다. 연구모형은 자기상관 문제를 고려한 확률효과 GLS(Random effects Generalized Linear Square)모형을 이용하여 분석하였다. 분석결과, 저축은행의 지배주주지분율과 사업다각화의 관계는 유의한 양(+)의 값을 가지는 것으로 추정되었다. 즉 지배주주지분율이 증가할수록 사업다각화를 대리하는 변수인 비이자수익률이 증가하는 것으로 나타났다. 이는 위험회피가설을 지지하는 결과이며, 지배주주지분율이 높을수록 사업다각화를 통해 자신의 자산위험과 고용위험을 축소시키기 위해 적극적인 다각화 전략을 추진하는 것으로 나타났다.

The purpose of this paper is to analyze factors affecting the net income of regional and industrial fisheries cooperatives in South Korea using panel data. This paper utilizes linear or GLS regression models such as pooled OLS model, fixed effects model, and random effects model to estimate affecting factors of the net income of regional and industrial fisheries cooperatives. After reviewing various tests, we eventually select random effects model. The results, based on panel data between 2013 and 2018 year and 64 fisheries cooperatives, indicate that capital and area dummy variables have positive effects and employment has negative effect on the net income of regional and industrial fisheries cooperatives as predicted. However, debt are opposite with our predictions. Specifically, it turns out that debt has positive effect on the net income of regional and industrial fisheries cooperatives although it has been increased. Additionally, this paper shows that the member of confreres does not show any significant effect on the net income of regional and industrial fisheries cooperatives in South Korea. This study is significant in that it analyzes the major factors influencing changes in the net income that have not been conducted recently for the fisheries cooperatives by region and industry.

This study aims to assess the impact of ownership structure of commercial banks on bank credit risk in Vietnam. The authors used the unbalanced table data of 28 commercial banks in the period from 2004 to 2020 with 439 observations. The ratio of loan loss provisioning to loans (CR) is selected as a dependent variable representing credit risk at commercial banks. The regression methods used include: least squares method (OLS), fixed-effect model (FEM), random-effect model (REM) and general least squares method (GLS). The results reveal that, with interaction variable between the ratio of equity to total assets and foreign ownership, the national GDP annual growth rate is negatively associated with credit risk. With the ratio of equity to total assets, the interaction variable between equity and state ownership, and bank size have a significant positive impact on credit risk. In addition, inflation has negligible impact on the credit risk of commercial banks in Vietnam over the research period. The findings of this study suggest that, if foreign-owned banks increase equity capital, there will be a stronger impact on reducing credit risk than other banks. On the other hand, when state-owned commercial banks in Vietnam increase equity, they will have higher credit risk.

This study analyzes the effects of participation in the global production network on the income inequality using panel data from 2005 to 2016 for 63 countries. In this study were used fixed effects model with autocorrelation, random effect model with autocorrelation and the GLS method. Results are as follows: First, the economic development level supports the Kuznets hypothesis. And then, the forward participation in global value chains increased income inequality, and the backward participation decreased income inequality. In order to derive more detailed estimation results, we analyzed OECD countries and non-OECD countries. First, OECD countries featured decreased, but increased beyond a certain level as a U-shaped curve, that did not support the Kuznets hypothesis. In contrast, non-OECD countries followed the Kuznets U-curve. Second, participation in the global production network showed that both OECD and non-OECD countries featured increased income inequality. In contrast, backward participation appears to mitigate income inequality both in OECD and non-OECD countries. Finally, the ratio of labor and capital is significant in mitigating income inequality in non-OECD countries in which they feature backward participation in production networks. This can be interpreted as developing economies participate in the global production network due to increased capital accumulation and increased the labor productivity.

This paper examines the relationship between ownership structure and level cash holdings in an emerging country, namely, Saudi Arabia, by constructing a corporate governance mechanism (foreign ownership, family ownership, institutional and managerial ownership). This paper uses data from 100 listed firms at Saudi Stock Exchange (TADAWUL) from 2011 to 2019. The firm's decision to hold cash has come to the fore in the last two or three years as a result of the recent global financial crisis, and the impact that this has had on the firms' ability to raise funds from external sources. Using the random-effect generalized least square (GLS) regression model, the findings reveal that foreign and family ownership negatively influences cash holdings, while managerial ownership has a positive association with cash holdings. Further, institutional ownership did not have a direct effect on cash holdings in Saudi Arabia. Our results suggest that ownership structure include foreign ownership, family and managerial ownership is an essential vehicle to promote the performance of cash holding of all the 100 public-listed non-financial firms in Saudi Arabia. We recommend that sound policies should be targeted toward foreign ownership, family, and managerial ownership since they are essential to improve cash holding in Saudi Arabian firms.

Purpose - This study aims to examine the direct impact of corporate social responsibility initiatives on firm technological innovation and the moderating effect on the relationship between firm technological innovation and corporate value. Design/methodology/approach - This study collected 13,298 firm-year data by selecting A-share companies listed on the China Shenzhen Stock Exchange and Shanghai Stock Exchange from 2010-2017. This study runs the multivariate regression using random effect generalized least squares (GLS) regression model. Findings - The research results of this study are as follows. First, corporate social responsibility initiatives do not increase the firm technological innovation, but rather reduce it. Second, firm technological innovation generally improves corporate value, whether it is book value or market value. Third, corporate social responsibility initiatives reduce the positive influence of firm technological innovation on corporate value. Research implications or Originality - There may be discussions on whether Chinese patent application data is a good indicator of the innovation of Chinese companies, but previous studies prove that the number of patent applications has a significant correlation with R&D expenditures or financial performance. However, there is a clear limitation in that it is not possible to confirm the result of registration after a patent application, but it is expected that such limitations can be overcome by using patent registration information or detailed citation documents in the future.

본 연구에서는 총수 및 그 일가에 의해 절대적인 영향력을 받고 있는 대규모기업집단이 그렇지 않은 기업에 비해 이익조정행위에 차별적으로 관여하는지 고찰한다. 본 연구는 선행연구에서 간과한 기업특성 및 잠재적 이분산에 기인한 내생성 문제를 통제하고자, 1992년부터 2010년까지 19년 동안 268개의 기업이 반복적으로 관찰되는 패널데이터를 이용한 확률효과 GLS 분석을 수행하였고, 추가분석에서는 잠재적 이분산성을 통제하고자 Hausman and Taylor검증을 실시하였다. 본 연구의 결과를 요약하면 다음과 같다. 재벌집단에 속해 있는 기업들의 발생액을 이용한 이익조정행위는 그렇지 않은 기업들의 이익조정행위 수준과 유의한 차이를 보이지 않는 것으로 나타난 반면 실제이익조정행위를 덜 행하는 것으로 나타났다. 이는 미래경영성과 및 장기주가에도 부정적인 영향을 미치고, 기업가치 또한 크게 오인시키는 실제이익조정행위를 대규모집단이 회피한다는 것으로 해석할 수 있다. 본 연구는 재벌기업의 장기간 시계열특성과 횡단면적 특성을 동시에 고려한 패널데이터를 이용하여, 재벌기업과 이익조정의 관련성에 대한 보다 신뢰할 수 있는 결과를 제공했다는 점에서 의미가 크다고 할 수 있다.
