This paper examines the relationship between diversification and financial performance of community credit unions in Korea from 2011 to 2017. To do so, I employ fixed-effects panel analyses using credit union level panel data collected from the National Credit Union Federation of Korea. This study finds evidence that business diversification is likely to lower the ratio of troubled loans, which means improving asset quality of credit unions. However, the relationship between diversification and asset quality is not linear but nonlinear, which means over-diversification would have negative effects on asset quality. Next, diversification tends to increase profitability. Specifically, although diversification results in a rise in expenditures, an increase in profits made by diversification outweighs the rise in expenditures, which contributes to profitability. Put together, diversification would be a good business strategy to improve both profitability and asset quality. Given a result that fast loan growth deteriorates asset quality, credit unions' managers might adopt the diversification strategy to enhance asset quality, and not to pursue their own objectives motivated by moral hazards.

Purpose - In this study, we examine the factors related to the asset allocation decisions of individual investors who 1) directly invest in stocks or bonds, 2) indirectly invest in various fund products (excluding CMA and MMF), and 3) invest in both products. Design/methodology/approach - We collect a sample of 3,000 individual investors and investigate the factors influencing investment behavior, especially the diversification tendency in asset allocation, with the "Investor Behavior Survey" that is conducted jointly by the Korea Financial Investment Association and the Korea Gallup Research Institute in 2011 and 2012. Findings - Our regression analyses estimate the marginal effects of various factors such as the amount of total financial assets, monthly income, occupation, age, and gender. The results reveal that male investors with manual labor occupations were less inclined to diversify their investments compared to female investors in office jobs. Additionally, higher monthly income is associated with a greater inclination toward diversification. Therefore, if a positive relationship exists between income and educational level, we may suggest that higher educational levels lead to a greater tendency for diversification. Research implications or Originality - Interestingly, investors who engage in direct investments tend to exhibit a weaker diversification tendency as the amount of their direct investment increases. On the other hand, investors who engage in both direct and indirect investments show a weaker diversification tendency as the amount of total financial assets increases. This suggests that the investment style of investors is closely related to their diversification behavior.

We analyzed the structures and properties of the global financial market networks using social network analysis approach. The Minimum Spanning Tree (MST) lengths and networks of the global financial markets based on the correlation coefficients have been analyzed. Firstly, similar to the previous studies on the global stock indices using MST length, the diversification effects in the global multi-asset portfolio can disappear during the crisis as the correlations among the asset class and within the asset class increase due to the system risks. Second, through the network visualization, we found the clustering of the asset class in the global financial markets network, which confirms the possible diversification effect in the global multi-asset portfolio. Meanwhile, we found the changes in the structure of the network during the crisis. For the last one, in terms of the degree centrality, the stock indices were the most influential to other assets in the global financial markets network, while in terms of the betweenness centrality, Gold, Silver and AUD. In the practical perspective, we propose the methods such as MST length and network visualization to monitor the change of the correlation risk for the risk management of the multi-asset portfolio.

This study seeks to determine if the efficiency of bank human resources, as played by human capital, impacts the performance and diversification of banks. This study uses secondary data from data obtained from 385 commercial banks in 33 countries in Asia during the 2010-2020 period with the diversification analysis method. We use the Z-score to measure the amount of standard deviation that must be from earnings (ROAA). We examined it using the Tobit regression technique. According to the regression estimation results, human capital has a significant role in the performance and effective diversification of Asian banks. The human capital efficiency coefficient (HCE) is significantly negative with the cost-to-income ratio (CTIR) and significantly positive with Profitability, Financial Stability, and cost efficiency score. The level of efficiency of human resources has an effective role in increasing human capital which has an impact on bank diversification and performance. The development of human resources in a human capital framework plays an important role in the diversification and improvement of bank performance. Human capital has a significant role in the performance and effective diversification of Asian banks. The level of efficiency of human resources has an effective role in increasing human capital which has an impact on bank diversification and performance.

본 연구는 투자 포트폴리오를 구성함에 있어 금융자산 뿐만 아니라 비금융자산 중 최근 대중 투자자들로부터 관심을 가지고 급부상하고 있는 음악저작권 조각 투자를 포함시켰을 때 얻을 수 있는 포트폴리오 분산 효과를 검증하였다. 국내 음악저작권 자산의 투자와 관련한 지수가 발표된 2019년 1월부터 2022년 6월까지 42개월간의 기간 동안의 데이터를 활용하여 전통적 글로벌 분산 투자 포트폴리오를 구성하고, 해당 포트폴리오에 음악저작권 투자 지수를 포함시킨 비금융자산 편입 포트폴리오를 추가로 구성하여 분석하였다. 분석 과정에서 포트폴리오 자체가 발생시키는 효과보다는 비금융자산인 음악저작권 자산의 포함 여부에 따른 개선 효과를 확인하기 위해 기본적으로 활용되는 포트폴리오 전략인 단순보유, 지속 재조정, 평균-분산 최적화, 리스크패러티 등 네 가지 포트폴리오 전략을 활용하였다. 분석 결과 음악저작권 자산을 포함한 포트폴리오는 네 가지 포트폴리오 전략 모두에서 위험은 감소하였지만, 수익률은 개선되는 효과를 보여주었다. 이는 위험 대비 수익을 고려하는 지표인 샤프지수가 크게 개선되는 결과를 가져오는 것으로, 음악저작권 자산을 투자 포트폴리오에 포함시키는 것은 의미 있는 포트폴리오 분산투자 효과가 존재함을 보여주었다. 본 연구를 통해 전통적 금융자산을 통한 글로벌 분산투자 포트폴리오에 음악저작권 투자를 포함함으로써 유의미한 포트폴리오 분산투자 효과가 있음을 동적 자산 배분 관점에서 처음으로 밝혔다는 점에서 본 연구의 학술적 의미를 찾을 수 있으며, 나아가 비금융자산을 포트폴리오에 편입함으로써 포트폴리오 성과를 개선할 수 있는 가능성을 보여주었다.

본 연구는 국내 상장제약기업을 대상으로 치료제 질환분야의 다각화 결정요인에 대해 분석함으로써, 최근 화두가 되고 있는 치료제 질환분야에서의 전문화 또는 다각화 전략을 결정짓는 요인이 무엇인지 살펴보았다. 본 연구에서는 자산규모, 매출액, 수익성, 성장성 등 요인들을 설정하고 추가적으로 영업적인 특징을 나타내는 요인인 판매관리비율과 직원 수를 추가하여 이들이 다각화 전략에 어떠한 영향을 미치는지 확인하였다. 연구방법에서는 각 요인들이 다각화에 영향을 미치기까지 걸리는 시간을 감안하여 t-1부터 t-4까지의 시차를 고려하여 변수들을 추가하는 전진선택법 회귀분석을 시행하였다. 총 6가지 요인 중 자산규모와 직원 수, 수익성이 t-1의 시점에서 성장성은 t-2시점에서 다각화의 결정에 유의한 영향을 미쳤다. 국내 상장제약기업들은 자산규모가 클수록, 높은 수익성과 성장성을 가질수록 오히려 소수의 질환분야로 집중화하는 경향을 보였고, 직원 수가 많을수록 다양한 질환분야에 진출하였다. 이는 한 분야의 전문화를 위한 깊이 있는 연구개발의 투자를 위해서는 큰 자산규모와 수익성 및 성장성이 뒷받침이 되어야하기 때문일 것으로 생각된다. 본 연구는 국내 제약기업들이 경쟁력 있는 기업으로 나아가기 위해 자신에게 맞는 다각화 또는 전문화 전략을 세우는데 유용한 정보를 제공할 것으로 기대된다.

In Schumpeterian competition, superior profit arises from successful innovation created by firm's R&D strategy. Such R&D strategy diverges as time passes. This study examines empirically the effects of diverged forms of R&D strategy such as technological assets, technological diversity, and technological similarity on firm performance in Korean pharmaceutical industry. With the financial and patent data of 96 firms for 14 years from 1994 to 2007, we measured variables. And then we performed panel analysis with 3 years lag between dependent variable and other variables. The result shows that firm performance increases as technological asset and technological diversification increase. But technological similarity positively affects on firm performance in opposition to our hypothesis. We interpret and discuss these results and highlight the theoretical and practical implications of our findings.

Purpose - This study investigates the effect of MNEs' characteristics on the use of foreign currency denominated debt in the context of Korean firms. This study examines the relationship between MNEs and the use of foreign debt focusing on the accessibility to the capital market in addition to the motive of hedging against foreign exchange exposure. Research design and methodology - Probit estimation is employed for estimating significant factors in determination of the use of foreign debt by firms. The dependent variable is a dummy variable to indicate whether a firm uses foreign debt or not at the end of 2004. Independent variables include foreign subsidiaries ratio, export to sale, R&D expenditure to sale, and credit rating. Results - The results show that the interaction between the level of internationalization represented by intra-regional diversification and the strategic characteristics embedded in the region of entry affects the use of foreign debt. In case of a high level of diversification within the developing region with a strong pursuit of asset exploitation, MNEs are more likely to use foreign debt, whereas a high level of diversification within the developed region with a strong pursuit of asset seeking, MNEs are less likely to use foreign debt. Conclusions - The differences between MNEs in terms of intra-regional diversification, strategic orientation, and the accessibility to capital markets as well as the hedging motive affect the use of foreign debt.
