The aim of this study is to examine the relationship between globalization and income distribution in Korea. In order to identify the key determinants, the study investigates the effects of trade openness, inward and outward FDI flows, and per capita GDP on income distribution. The study uses methodology of unit root and co-integration technique as well as an error correction model over 1992 to 2011 by using annual data. The empirical findings showed that income inequality is reduced as trade openness and the per capita GDP increase. Meanwhile, income inequality is deteriorated as inward and outward FDI flows increased. In addition, the study revealed that the negative effect of inward FDI flows on income inequality is greater than that of outward FDI flows. This result supports the Feenstra and Hanson (1997) hypothesis. Overall the globalization process can be beneficial for the Korean economy, but its nature should be closely monitored regarding income distribution.

The purpose of this paper is to estimate the revenue function of the personal income tax of Korea. Unlike the traditional approach employing the data adjustment, this paper explicitly includes the explanatory variables of the tax rate or schedule in the revenue function and further estimates the functions by income sources such as labor, interest, global, and dividend incomes. One of the main findings is the GNP elasticity of the combined personal income tax is around 1.2 when evaluated on the basis of the estimates of the GNP elasticities of tax revenue from respective income sources, which is somewhat smaller than those in the previous studies. Another interesting result is that the GNP and interest rate elasticities of the interest income, are found around one and .15 respectively, as expected. Also, the estimate of the tax-free income coefficient is significantly negative in the labor income tax revenue function.

본 논문에서는 한국노동연구원에서 1998년에 수집한 "한국노동패널조사" 자료를 이용하여 소득과 만족도로 측정된 주관적 삶의 질간의 관계를 집중적으로 검토해 보았다. 가구 소득, 가족 관계, 여가활동, 주거활동, 근로활동의 5개 삶의 개별영역들에 대한 만족도가 전반적인 삶의 만족도의 50% 이상을 설명되며, 수입에 대한 만족과 전반적 만족간에는 체감의 관계가 있는 것을 발견하였다. 우리 나라 사람들은 자신의 생활에 보통 이하의 만족을 느끼고 있다고 보고하고 있다. 실제 소득과 소득만족도 와 의 연관 은 그렇게 크지 않으며, 이는 가구 소득의 경우에나 개인 소득의 경우에나 유사하게 실제 소득이 소득만족도의 10%정도의 변이만을 설명하고 있다. 서구의 연구 결과와 유사하게 모두 외적인 조건들을 생활만족도의 설명변수로 한 희귀 분석 결과는 변량의 10%정도만을 설명할 뿐인 것으로 나타난다. 것으로 나타난다.

The study aimed to investigate the effects of differences between personal income and social deprivation on the association between cardio-cerebrovascular disease (hypertension, stroke) and periodontal disease. This study used 12 years of cohort data from the Korea National Health Insurance Service covering the years 2002 to 2013. Among the patients aged more than 40 years who had received treatment for periodontal disease 224,067 and 284,730 who had not received treatment for hypertension and stroke, respectively, were included in the analysis. The Kaplan-Meier analysis revealed differences in the rate of treatment for cardio-cerebrovascular disease (hypertension, stroke) according to regional differences, the rate of treatment increased as the composite deprivation index value increased. The difference in treatment rates for cardio-cerebrovascular disease (hypertension, stroke) according to income was found to be higher in the treatment group with low income. This study empirically proved that the association between systemic disease and periodontal disease varies depending on personal income and the regional socioeconomic deprivation level. This shows that the clinical influence of periodontal illness on systemic disease differs according to the personal socio-demographic characteristic and residential area and that an individual's characteristic (income and the regional) needs to be considered along with the patient's clinical intervention in the disease treatment process.

This paper investigates how individual labor income is determined by initial conditions - such as educational attainment, age, and sex - and all the other conditions. Using KLIPS (Korea Labor & Income Panel Study) database, the paper finds, first, that over the period of 1998-2008, cross-sectional income distribution has deteriorated for the whole sample but not within each age group. Second, income mobility defined by the relative importance of initial conditions in individual income disparities has moderately increased in most age groups.

The objective of this paper is to analyze expenditure structures and impact factors of household's transportation cost in order to provide policy-maker with quantitative and economic information for reducing household's transportation costs, using 1995-2007 household survey data. For this purpose, this study performed various economic analysis, including econometric regression analysis and income re-distributional effects. The four models were separately estimated with dependent variable (personal and public costs, public transit and private car costs) and independent variables (family, employ, age, education, cars, household income, region dummy variable). In addition, We analyzes impacts of transport policy instruments on the transportation expenditure. These instruments include changes of oil price and public transit fare, reform of public transport system, and extension of subway facilities. Finally, income re-distributional effects before and after transportation expenditure, using Pechman-Okner (PO) index and Wolfson index.

This study analyzes the influence of player's social factors on their game play. By conducting a survey of 1,000 general public in Korea, this study aims to understand how game player's social factors influence on their game play behavior: whether they play a game or not, how long they play, and how frequent they play. The survey result suggests that there are some relations between player's social factors and their game play behaviour. The personal factors such as sex, age, monthly income level are seen to have influence on the length and frequency of their game play. Players' the social factors such as social status, social activity participation level and confidence level also have influence over their game play behaviours as well. And the influences are seen to be different depending on whether it's on online game or mobile game.

사회보험(Social Insurance)은 노령(老齡) 등 미래(未來)에 확실(確實)히 발생(發生)할 사안(事案)뿐 아니라 질병 등 불확실(不確實)한 사안(事案)에 의한 소득(所得)의 상실(喪失)을 보상하기 위한 보험(保險)의 역할을 한다. 대부분의 사회보험연구는 이 불확실성(不確實性)이 배제된 모형의 분석을 하고 있는데 본고(本稿)에서는 그러한 불확실성(不確實性)이 존재(存在)할 때 사회보험이 개인의 은퇴시기 결정에 미치는 영향을 분석하였다. 사회보험은 노동기(勞動期)로부터 은퇴기(隱退期)로의 소득이전(所得移轉)일 뿐 아니라 일을 할 수 있는 상태로부터 질병 등의 불확실한 사안(事案)에 의해 초래된, 일을 할 수 없는 상태로의 소득이전(所得移轉)도 된다. 이 두 번째의 역할 때문에 사회보험은 개인(個人)의 은퇴시기(隱退時期)를 늦추는 효과를 보일 수 있다. 특히 사회적 최선적정은퇴시기(最善適正隱退時期)(first best optimum)는 사회보험이 전혀 없는 경우의 은퇴시기가 보다 늦다. 반면 어느 일정(一定)한 시점(時點) 이후에만 사회보험(社會保險)의 수혜(受惠)가 가능(可能)하다면 이는 오히려 조기은퇴(早期隱退)를 초래(招來)하게 된다는 것을 보였다.
