This paper examined how men and women differ in the attitude and behaviour of financial risk tolerance. The results showed that women were less risk seeking than men in financial risk tolerance. The results of the investment simulation indicated that men invested in higher risk assets like stock. In contrast, women prefered to invest in lower risk assets like real estate. The results of multiple regression analysis showed that if investors have the propensity to take more risk they allocated their money to higher risk assets in the simulation. This analysis also showed that the surveyed respondents invested in risky assets if they had experience in high risk investment in the past.

This study focuses on the factors that make the financial structure of hospitals in Korea different, and on recommended courses of action that could be very helpful to hospitals in maintaining a sound financial structure. Data used in this study were collected from 132 hospitals with complete general data of present conditions as well as financial statements. They were chosen from the 174 hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1996 to 2000 for the purpose of accrediting training hospitals. The dependent variable in this study is financial structure. It consists of liabilities as against total assets (total liabilities to total assets, short-term liabilities to total assets, long-term liabilities to total assets, short-term borrowings to total assets, long-term borrowings to total assets). The independent variables are ownership type, hospital type, location, whether or not a representative is a director of the hospital, the possibility of changing a hospital director, bed size, period of establishment, asset structure, profitability, growth, tax shields, business risk, competition. The factors that appear to have the strongest impact on the liabilities to total assets of all the hospitals sampled are ownership type, hospital type, profitability, tax shields, and business risk. It was found that not-for-profit private hospitals and for-profit private hospitals have more liabilities than public hospitals, and tertiary medical institutions have less liabilities than the secondary general hospitals. Moreover, hospitals earning more at the expense of high business risk have a distinct tendency to lower liabilities. Concerning the current ratio, it was found that factors such as ownership type, hospital type, period of establishment, asset structure, and business risk are the more significant variables. The current ratio of public hospitals is higher than that of both not-for-profit private hospitals and for-profit private hospitals, and the current ratio of tertiary medical institutions is higher than that of general hospitals. As business risk is higher in hospitals compared to other businesses, the current ratio becomes higher; this is because it is assumed that for fear of bankruptcy, hospitals lessen liabilities to total assets. On the other hand, as hospitals become older, the fixed assets to total assets become lower. It is remarkable that in hospitals, the factors affecting liabilities to total assets have an opposite regression coefficient sign against factors affecting current ratio. It brings out the same results borne out by the old financial theories and researches, in which a lot of the liabilities of hospitals are considered as the cause of worsening liquidity. Therefore, it is very important for hospitals to maintain a sound financial structure in order to survive using the rational acquisition and maintenance of capital.

본 논문은 단일 종목에 투자금을 전액 투자하는 것에 비해 다수의 종목에 분산투자하는 것이 투자 위험을 보다 감소시킬 수 있다는 포트폴리오 최적화 문제를 다룬다. 널리 알려진 Markowitz의 수익률에 대한 평균-분산 기법(MV)은 위험요인인 분산(또는 표준편차)을 감소시키기 위해 지배원리를 적용하여 효율적 투자선에 있는 종목들을 대상으로 분산투자하는 포트폴리오를 구성하였다. 반면에, 본 논문에서는 최소표준편차를 가진 종목을 필수 투자종목으로 선정하고, 필수 투자종목과 비양(음의, 무)의 상관관계를 갖는 종목들을 대상으로 포트폴리오를 형성하였다. 제안된 방법을 실험한 결과 MV에 비해 보다 적은 위험(표준편차)을 보였다.

Objectives This study aims to assess the status quo of depression among Korean physicians and identify stressors and psychiatric assets related to it. Methods The questionnaire was designed to assess depression, stressors, burnout and psychiatric assets. 343 physicians were included in the analyses. Results Physician depression in Korea was found to be related to several daily life stressors and occupational stressors. It was also related to higher burnout and lower psychological assets. Physicians who reported workplace problems, familial problems, and mannerism were at higher risk of depression while who reported passion (in psychiatric assets) were at lower risk of depression. Conclusions This study identified factors affecting physician depression in Korea. Further research would benefit physicians and their patients by identifying and testing various, including personal and organizational, intervention methods.

This study aims to investigate the impact of the multimarket contract on risk-adjusted profitability. Risk-adjusted profitability is measured in terms of risk-adjusted return on assets. This study employs dynamic panel data of 27 commercial banks in Vietnam using the GMM estimator to test the multimarket contact hypothesis in the Vietnamese banking sector. The results show that there is a negative impact of multimarket contact on the profitability of banks. Multimarket contact, deposit to asset ratio, non-interest income to total income, GDP growth rate, Worldwide Governance Indicator (WGI), and operating cost to assets are the major determinants of risk-adjusted profitability of commercial banks. Our main findings show that Vietnamese banks' focus to increase the multimarket contact may lead to lower profitability and there is evidence that supports theory predictions, since the average number of contacts among banks, bank size, and capitalization are positively related to risk-adjusted profitability. The study has policy implications for commercial banks in that they should not only focus on interest as a source of income and diversify their income source from non-interest income as well since it helps to improve risk-adjusted profitability for them.

본 연구는 기업의 자산 노후화가 원가의 비대칭성에 미치는 영향을 분석하였다. 원가의 비대칭성이란 매출액이 증가할 때 원가의 증가율보다 매출액이 하락할 때 원가의 감소율이 더 낮은 것을 가리킨다. 선행연구에서는 경영자의 설비용량 조정이나 유형자산의 비중이 높을수록 원가의 비대칭성이 보다 강하게 나타난다는 결과를 제시하였으나 주로 경영자의 재량적 의사결정에 산물로써 진행되었다. 그러나 원가의 비대칭성은 설비자산의 규모와 비중, 자산의 노후화율 등과 같은 구조적인 문제에 기인한 현상이 존재할 것으로 예상되어 가설을 검증하였다. 실증분석결과는 다음과 같다. 첫째, 자산의 노후화가 높을수록 총원가, 판매비와관리비의 하방탄력성이 나타났다. 둘째, 유형자산의 비중이 높은 경우 설비자산의 노후화가 높을수록 매출원가의 하방경직성이 나타났다. 이상의 결과는 선행연구가 주로 경영자의 의사결정, 설비용량의 조정, 무형자산의 비중에 관해 다루었다면 본 연구는 설비자산의 노후화와 설비자산의 집중도를 고려하여 분석함으로써 선행연구를 확장하였다.

본 연구는 중국 상업은행의 대출자산에 대한 위험도를 확인하고, 중국 상업은행의 안정성에 영향을 주는 요인이 무엇인지 분석하고자 함이 목적이다. 또한 자산규모 2천억 위안을 기준으로 중국 상업은행을 구분하고, 규모에 따른 안정성의 차이를 규명한다. 분석결과는 다음과 같다. 첫째, 중국 상업은행의 가계대출비중과 기업대출비중이 증가할수록 은행의 안정성은 낮아지는 것으로 추정되었다. 현재 중국 금융당국이 은행의 부실자산 비중을 낮추기 위해 대출자산을 보수적으로 운용하도록 제한하고 있으나, 향후 적정 예대율 기준을 설정하여 대출자산에 대한 선제적인 리스크 관리가 필요할 것이다. 둘째, 은행자산 2천억 위안을 기준으로 하여 대형은행의 안정성을 분석한 결과 규모가 큰 대형은행의 안정성이 더 낮은 것으로 추정되었다. 대형은행들은 대마불사의 원칙에 근거하여 공격적인 대출자산운용이 이루어질 가능성이 크므로 안정성이 더 낮아질 수 있는 만큼 앞으로 지속적인 부실자산에 대한 관리가 요구된다. 본 연구는 중국 상업은행의 대출자산 운용이 재무안정성에 미치는 영향을 추정함으로써 중국 상업은행들의 안정성 제고를 위한 바로미터가 될 것이라고 본다. 특히 대형은행들의 안정성을 규명해 봄으로써 대형은행의 취약점을 진단하여 지속가능한 금융산업 발전을 위한 전략이 요구됨을 시사한다.

The purpose of this study is to investigate empirically the characteristics of financial structure by using 76 fisheries corporations in Korea, and to suggest implications of the empirical results for government's financial policy for fisheries corporations. For the empirical test, we choose the following factors as the explanatory variables of cross-sectional regression analysis:firm-size(SIZE), collateral value of assets(TFATA), business risk(BRISK), growth(GROWTH), effective tax(ET), profitability(PROFIT). Two different debt ratios are used as dependent variables. One is defined as the ratio of total debt to total assets and the other is as that of long-term debt to total asset in terms of book value. The sample consists of 76 fisheries firms and sample period is 14 years from 1982 till 1995. From the results of cross-sectional regression analysis, the adjusted R$^2$values were high, 16∼79% and the overall F values indicated to be statistically significant. The results of cross sectional regression analysis show that the characteristics of financial structure fur fisheries corporations are as follows ; (1) Firm-size and collateral value of assets are the major factors of financial structure for fisheries corporations. That is, the larger firm-size the higher is debt ratio. This means that financial institutions conventionally lend more collateral loans with fixed assets like land, building rather than management capacities or credits. (2) To be consistent with a pecking-order theory, the higher is profitability the lower is debt ratio in fisheries corporations. (3) Corporations with high effective tax rate have lower financial leverage. Although the empirical results are inconsistent with traditional static trade-off theory, we think it would be attributed to government's various tax shelterings for fisheries which are likely to reduce tax shield effect of interests.

The study empirically examines the effects of loan portfolio diversification on bank risk and return in the nascent banking market of Vietnam. Loan portfolio diversification is captured through the Hirschman-Herfindahl index and the Shannon Entropy with sectoral exposures. We access each bank's financial reports to collect the required data, especially the breakdown of sectoral loan portfolios, thus constituting a unique dataset. To compute bank return, we use the traditional accounting indicators, including return-on-assets, return-on-equity, and net-interest margin. For bank risk, we utilize the loan-loss provisions and non-performing loans relative to gross customer loans. Using a sample of 30 commercial banks over the period from 2008 to 2019 and the system generalized method of moments estimator for the dynamic panel, we indicate the downsides of portfolio diversification. Concretely, we observe that all diversification measures exhibit significantly negative signs in all regressions across different bank return proxies. At the same time, the estimates display the significant and positive impact of diversification on the non-performing loan ratio. Hence, sectoral loan portfolio diversification significantly hampers bank performance in both aspects of lower return and higher credit risk. The results are robust across a rich set of bank performance and portfolio diversification measures.
