This study examines whether expenditures in information technology (IT) are associated with increases in Tobin's q ratios, a measure of management performance, in the banking industry. The association between IT expenditures and Tobin's q ratios is different, depending upon the banks' size (national vs regional) and strategic orientation (wholesale vs retail), in the Korean commercial banks for the period studied 1990-1996, For national commercial banks which have more clients and electronic banking systems than regional banks, IT expenditures appear to increase Tobin's q ratios. This may indicate that IT is linked to the ability to achieve economies of scale or network effects when large banks use IT as a strategic tool. The association between IT expenditures and management performance measures is also positive and statistically significant for retail-oriented banks. This research makes two important practical contributions with respect to financial reform. First, the evidence suggested that Korean commercial banks need to apply IT strategy in conjunction with restructuring strategy to be a super-bank and, hence, reap substantial competitive advantage from IT applications. Second, since the government recently encouraged commercial banks to increase credit loans as a means of financial reform, most banks tend to focus on retail banking. IT used in the retail banking sector contributes to improve management performance as the evidence suggested.

The purpose of this study is to examine the effects of economic uncertainty on MNC investment in Malaysia from 2009 to 2019 by employing an ARDL method. The results revealed that Economic Policy Uncertainty (EPU) has a positive association with the capital expenditures of Nestle, British American Tobacco, and Public Bank in the long run. In a similar period, the Gross Domestic Product (GDP) is positively significant with the capital expenditures of British America Tobacco and Heineken. However, inflation is negatively related to the capital expenditures of British America Tobacco and Heineken. Additionally, the exchange rate has a significant and negative relationship with the capital expenditures of Nestle and Petronas, while the ECT value is negative and significant in the short run, hence confirming that co-integration exists. In view of this, it is imperative that the government plays a prerogative role to support MNC operations, as MNCs foster the developing countries' economic development through facilitating full employment. This study sets to enhance the personal knowledge of those with a strong interest in the Malaysian financial market. As long as MNCs believe that the Malaysian market has the potential to grow, they will continue to invest for the benefit of the country.

Objectives: Equity in financial protection against healthcare expenditures is one the primary functions of health systems worldwide. This study aimed to quantify socioeconomic inequality in facing catastrophic healthcare expenditures (CHE) and to identify the main factors contributing to socioeconomic inequality in CHE in Iran. Methods: A total of 37 860 households were drawn from the Households Income and Expenditure Survey, conducted by the Statistical Center of Iran in 2017. The prevalence of CHE was measured using a cut-off of spending at least 40% of the capacity to pay on healthcare services. The concentration curve and concentration index (C) were used to illustrate and measure the extent of socioeconomic inequality in CHE among Iranian households. The C was decomposed to identify the main factors explaining the observed socioeconomic inequality in CHE in Iran. Results: The prevalence of CHE among Iranian households in 2017 was 5.26% (95% confidence interval [CI], 5.04 to 5.49). The value of C was -0.17 (95% CI, -0.19 to -0.13), suggesting that CHE was mainly concentrated among socioeconomically disadvantaged households in Iran. The decomposition analysis highlighted the household wealth index as explaining 71.7% of the concentration of CHE among the poor in Iran. Conclusions: This study revealed that CHE is disproportionately concentrated among poor households in Iran. Health policies to reduce socioeconomic inequality in facing CHE in Iran should focus on socioeconomically disadvantaged households.

Purpose - This study investigates the effects of foreign investor ownership on firm innovation and the different stages of the firm innovation process for business group affiliation (affiliated firms) and nonaffiliated firms. Design/methodology - Research and development (R&D) intensity is used as a proxy for firm innovation. We use a sample of 7,655 firm-year observations of Korean listed firms from 2001 to 2015. To identify the distinct features of business group affiliation and how foreign investor ownership affects firm innovation, we divide the sample into affiliated and non-affiliated firms. Moreover, we classify total R&D expenditures as research and development expenditures. Findings - This study finds a positive relationship between foreign investor ownership and innovation in non-affiliated firms. However, the foreign investor ownership's role in facilitating firm innovation does not influence business group affiliation. Moreover, the results show that foreign investor ownership encourages firms to increase research expenditures, which is the amount spent in the early stages of a firm's R&D process. Originality/value - Existing studies have overlooked the distinct features of business group affiliation and the different characteristics of research and development expenditures. Thus, this study considers the distinct features of business group affiliation and investigates how foreign investor ownership affects different stages of R&D activities.

This study compared one-child households' economic structures between those who determined not to have more children and those who have a birth plan. This study examined the demographic characteristics and economic variables such as income, consumption expenditures, assets. debt, and a subjective evaluation of future economic status. Especially, it compared the effects of socioeconomic variables on expenditures on a child between low-fertility and birth-planned households. From a questionnaire completed by a husband or wife of one-child households, 154 low-fertility households and 201 birth-planned households were obtained. A t-test, chi-square test, multiple regression analysis and a dummy variable interaction technique were used. The findings of this study are as follows: First, low-fertility households were older, had higher income, and had more educated, employed wives. Their marital duration was longer, and their child was older than those of birth-planned households. Second, low-fertility households had higher consumption expenditures than did birth-planned households. Especially, expenditures of apparel and shoes, health care, education, and entertainment were significantly higher for low-fertility households. Also, low-fertility households spent more than did birth-planned households on a child. However, low-fertility households had significantly more debt than did their counterparts, and their expectation level of future economic status were lower than that of birth-planned households. Third, the effects of socioeconomic variables on expenditures on a child were different between low-fertility and birth-planned households. Age, education level, husband's occupation, wife's employment status, income, net asset, and subjective evaluation of future economic status showed significant differences. Income elasticity of expenditure on a child was significantly higher for low-fertility households than their counterparts.

본 연구는 국내외 문헌고찰을 통하여 건강보험과 산재보험, 자동차보험을 중심으로 선진국의 국민의료비 관리제도를 살펴보고, 우리나라 국민의료비 관리제도의 문제점을 파악하여 올바른 국민의료비 관리방안을 제안하는데 목적이 있다. 분석결과 첫째, 선진국의 경우 국민의료비를 단일기관에서 통합해 운영하면서, 동일한 수가와 급여기준을 가지고 운영하고 있었다. 즉, 의료비 발생원인에 관계없이 동일한 기관에서 동일한 기준으로 통합관리하고 있었다. 둘째, 우리나라의 경우 국민의료비를 보험제도별로 다른 기관에서 분리운영하면서, 서로 다른 의료비 심사·평가, 수가를 적용하고 있었다. 이로 인해 동일증상과 상병임에도 불구하고 관리주체에 따라 의료이용량의 차이가 매우 컸다. 이러한 문제를 근본적으로 해결하기 위해서는 의료비발생의 원인이 무엇이든지 하나의 기관에서 동일한 수가체계와 기준에 근거해 통합관리해야 한다.

Background: Cancer imposes significant economic challenges for individuals, families, and society. Households of cancer patients often experience income loss due to change in job status and/or excessive medical expenses. Thus, we examined whether changes in economic status for such households is affected by catastrophic health expenditures. Materials and Methods: We used the Korea Health Panel Survey (KHPS) Panel $1^{st}-4^{th}$ (2008-2011 subjects) data and extracted records from 211 out of 5,332 households in the database for this study. To identify factors associated with catastrophic health expenditures and, in particular, to examine the relationship between change in economic status and catastrophic health expenditures, we conducted a generalized linear model analysis. Results: Among 211 households with cancer patients, 84 (39.8%) experienced catastrophic health expenditures, while 127 (40.2%) did not show evidence of catastrophic medical costs. If a change in economic status results from a change in job status for head of household (job loss), these households are more likely to incur catastrophic health expenditure than households who have not experienced a change in job status (odds ratios (ORs)=2.17, 2.63, respectively). A comparison between households with a newly-diagnosed patient versus households with patients having lived with cancer for one or two years, showed the longer patients had cancer, the more likely their households incurred catastrophic medical costs (OR=1.78, 1.36, respectively). Conclusions: Change in economic status of households in which the cancer patient was the head of household was associated with a greater likelihood that the household would incur catastrophic health costs. It is imperative that the Korean government connect health and labor policies in order to develop economic programs to assist households with cancer patients.

Although the universal health insurance, National Health Insurance (NHI), have improved access to health care and financial burden of health care costs for Koreans, limited coverage of the NHI leads to high out-of-pocket payment for health care. This study examines financial burden of household health expenditures by income level. Data from the Urban Household Expenditure Survey from 1985 through 2005 is analyzed and household expenditure is used as a proxy measure for income. Health expenditures include spending for inpatient care, ambulatory care and pharmaceuticals. If a household spends health expenditure above 40% of household consumption except for foods, that is defined as catastrophic health expenditure. Access to health care for the lowest income group had been improved for two decades relative to other income groups as well as in absolute term. However, both financial burden of health expenditures and the proportion of households that experienced catastrophic health expenditure had been increased in the lowest income group. Study findings have several policy implications. First, in terms of financial burden of health expenditures. the differences among income groups decreased until 2000 but it was worsen in 2005. This suggests that recent policies for extending NHI coverage are not enough to improve the disparity by income level. Second, a differential catastrophic coverage by income level would be an effective strategy that relieves financial burden for low income group. Third, since the catastrophic coverage is applied to only covered services by the NHI, additional strategy for uncovered services should be considered.

Objectives: Several epidemiological studies on medical care utilization prior to suicide have considered the motivation of suicide, but focused on the influence of physical illnesses. Medical care expenditure in suicide completers with non-illness-related causes has not been investigated. Methods: Suicides motivated by non-illness-related factors were identified using the investigator's note from the National Police Agency, which was then linked to the Health Insurance Review and Assessment data. We investigated the medical care expenditures of cases one year prior to committing suicide and conducted a case-control study using conditional logistic regression analysis after adjusting for age, gender, area of residence, and socioeconomic status. Results: Among the 4515 suicides motivated by non-illness-related causes, medical care expenditures increased in only the last 3 months prior to suicide in the adolescent group. In the younger group, the proportion of total medical expenditure for external injuries was higher than that in the older groups. Conditional logistic regression analysis showed significant associations with being a suicide completer and having a rural residence, low socioeconomic status, and high medical care expenditure. After stratification into the four age groups, a significant positive association with medical care expenditures and being a suicide completer was found in the adolescent and young adult groups, but no significant results were found in the elderly groups for both men and women. Conclusions: Younger adults who committed suicide motivated by non-illness-related causes had a higher proportion of external injuries and more medical care expenditures than their controls did. This reinforces the notion that suicide prevention strategies for young people with suicidal risk factors are needed.
