This study examined the interactive effects between social service use and economic hardship on the family conflicts among low-income families. We analyzed data from about 2,000 low-income families who participated in both the first and the second waves of the Korean Welfare Panel Study using a hierarchical logistic regression model. The main results are as follows. First, take-up rates of social services among low-income families were very low. Second, among the low-income families who did not use any social service, families who experienced more economic hardship were more likely to experience family conflicts. Third, the higher levels of economic hardship increased the positive effects of social service of reducing family conflicts. These findings suggest that the resource for the social services be concentrated on the low-income families who tend to experience more economic hardship and thereby family conflicts and that comprehensive social services be provided in the programs which aim to promote family relationships.

본고(本稿)는 빈곤문제(貧困問題)를 둘러싼 새로운 시각(視角)을 설명하고 빈곤대책(貧困對策)의 방향전환을 촉구하기 위해서 집필되었다. 복지차원(福祉次元)의 부조(扶助)에 의존하기보다는 스스로의 노동(勞動)에 의해 자립(自立)할 수 있도록 도와주는 것이 최선(最善)의 빈곤대책(貧困對策)이라고 보는 시각(視角)인 것이다. 세계은행(世界銀行) 둥이 빈곤대책(貧困對策)을 보더라도 가능한 한 자신의 노력(努力)과 노동(勞動)에 의해 자립(自立)할 수 있어야 하며 또한 그러한 기회가 최대한 보장되어야 한다는 점이 부각되고 있다. 사회부조(社會扶助)의 대상자들인 빈민(貧民)들이 개인적(個人的)으로나 자발적(自發的)인 조직화에 의해 시장경제(市場經濟)에 참여하여 적극적인 삶의 추구를 도모할 때 이는 취업증가를 통한 소득증가(所得增加), 나아가서 지역개발(地域開發) 및 국가경제성장(國家經濟成長)에도 기여하게 될 것이다. 더불어 사회적(社會的) 안정(安定) 및 정치적(政治的) 기반형성(基盤形成) 등 바람직한 외부효과(外部效果)를 창출할 가능성이 높게 된다. 본고(本稿)는 태동되기 시작한 빈민들의 생산협동조합운동(生産協同組合運動)에 초점을 맞추어 지역사회에 근거를 둔 경제공동체사업(經濟共同體事業)의 활성화를 강조하고 있다. 이로써 취업기회(就業機會)가 확충되고 지역개발(地域開發)이 촉진되며 그들의 소득증가(所得增加)를 통하여 탈빈곤(脫貧困)에도 도움을 줄 수 있을 것이므로 빈곤대책(貧困對策)의 우선순위(優先順位)가 여기에 두어져야 할 것이라고 제안하고 있다. 조금이라도 일할 수 있는 능력(能力)이 있다면 빈민(貧民)들은 협동조합(協同組合)을 결성하여 자립(自立)할 수 있도록 스스로 노력해 나가야 할 것인바, 이에 대하여 정부는 새마을금고(金庫) 등을 통한 금융지원(金融支援)과 조세감면(租稅減免)을 통하여 조직화를 지원하는 방향으로 인센티브를 제공해야 할 것이다.

본 연구는 단기소득과 장기소득에 대한 차등세제(差等稅制)(differential taxation)가 선도이자율, 기간프리미엄, 이자율의 기간구조 등에 미치는 영향을 이론적으로 분석하고 있다. 분석결과, 세금이 있을 경우 선도이자율(先渡利子率)은 미래이자율(未來利子率)의 추정치로써 하향편의(下向偏倚)(downward bias)를 가지며, 이러한 세금편의(稅金偏倚)(tax bias)의 크기는 장기소득세율(長期所得稅率)이 낮을수록 한계체감적으로 증가하고 미래이자율(未來利子率)이 상향 또는 평평한 구조를 가질 경우 잔존만기가 길수록 증가하며, 세금편의의 크기의 한계변화는 미래이자율(未來利子率)이 상향(上向)하고 있지 않는 한 장기소득세율(長期所得稅率)이 낮을수록 한계체감적으로 증가하는 것으로 나타났다. 따라서, 만기(滿期)가 길 경우 기간프리미엄이 음(陰)으로 나타나고 기간구조가 1년이 지나서는 모양이 다양하게 나타나고 있다는 Fama(1984)의 연구결과는 기존의 이자율의 기간구조(期間構造)에 관한 제이론(諸理論)들로써는 설명될 수 없으나, 본 연구가 분석한 음(陰)의 세금효과(稅金效果)에 의해서 설명될 수 있었다. 또한, 선도이자율이 우하향구조(右下向構造)를 가질 경우에는 장기현물이자율(長期現物利子率)이 보다 나은 미래이자율(未來利子率)의 추정치이며, 선도이자율이 우상향구조(右上向構造)를 가지는 경우에는 선도이자율(先渡利子率)이 현물이자율보다 우수한 미래이자율의 추정치인 것으로 분석되었다.

This paper estimates the effect of household size and its changes on income inequality. Household formation is an important inequality-reducing mechanism through income pooling and collective consumption. The increase in small households, reflecting lower fertility rate and the increase in both nuclear and old families, has weakened the inequality-reducing effect of household formation. In contrast, additional workers in households and their income have strengthened the inequality-reducing effect of household formation. Given the increasing trend of old families, these results suggest for a balanced policy package that promotes employment and does not discourage co-habitation in order to maintain the inequality-reducing effect of household formation.

This paper analyzes the machine learning predictions of the economic effects of Busan's strategic industries on the employment and income using the Ridge Regression and Lasso Regression models with regulation terms. According to the Ridge estimation and Lasso estimation models of employment, the intelligence information service industry such as the service platform, contents, and smart finance industries and the global tourism industry such as MICE and specialized tourism are predicted to influence on the employment in order. However, the Ridge and Lasso regression model show that the future transportation machine industry does not significantly increase the employment and income since it is the primitive investment industry. The Ridge estimation models of the income show that the intelligence information service industry and global tourism industry are also predicted to influence on the income in order. According to the Lasso estimation models of income, four strategic industries such as the life care, smart maritime, the intelligence machine, and clean tech industry do not influence the income. Furthermore, the future transportation machine industry may influence the income negatively since it is the primitive investment industry. Thus, we have to select the appropriate economic objectives and priorities of industrial policies.

This paper investigates the distinct characteristics of freehold and leasehold households living in the seven largest cities and the other areas. We employ the two-stage logit regression analysis to identify the marginal effects of wealth and income after controlling for the other one. We document the following results. First, households with more net wealth are more likely to reside in their own houses, regardless of living areas. Second, the pure income effect after controlling for wealth and other variables lowers the tendency of freeholders to live in the seven largest cities while increasing the tendency to live in the other areas. Furthermore, the income effects reduce the tendency to live in the former regions. Our results suggest that the pure income effects enhance preferences for a better living environment (e.g., larger spaces, better school districts, etc.), whereas the wealth effect increases the likelihood of freeholds.

As polarization and class reproduction between generations are considered to be serious problems in Korean society, increasing number of assortative mating, which means marrying between homogeneous family background, income class, and educational background, is on the spotlight socially. Some worry that the increase of assortative mating can reinforce closure of social mobility so it deepens inequality and limits class mobility between generations. This research analyzes the effects of accomplishment characteristics of husbands and wives and ascriptive characteristics of parents which consist the concept of assortative mating, on income, consumption, and assets those represent economic status of a family. The purpose of this research is to suggest empirical understanding on the role of assortative mating that affect on inequality within generations and income mobility between generations in Korean society. In the result of multiple regression analysis on the effect of assortative mating on income, consumption, and assets, high educational background was the factor that increase income and consumption level as accomplishment characteristics of assortative mating. As ascriptive characteristics of assortative mating, educational homogeneous of fathers was the factor that increased asset level. While accomplishment characteristics affect income and consumption, ascriptive characteristics of homogeneous had significant effect on assets. Thus, it was found that transfer between generations had effects around asset rather than income. In particular, ascriptive characteristics in young husbands and wives aged 20s or 30s had significant effect only on the assets.

This paper analyzes the distribution and determinants of income of the self-employed, in comparison with salaried workers. Relative to salaried workers, in general, the self-employed tend to have a larger dispersion of income and larger heterogeneity. In this regard, the quantile regression analysis was used, along with a typical OLS regression analysis. According to the empirical findings, the income of the self-employed is larger than that of salaried workers, and this difference is larger for higher income group. The marginal effect of education is larger for higher income groups for both the self-employed and salaried workers, implying the return on education is larger for higher income groups. In contrast, for self-employed women, the marginal effect of education is smaller for higher income groups. Put differently, the return on education in the labor market is larger for salaried workers and self-employed men of high income groups as compared to those of low income groups, whereas the opposite holds for self-employed women.

이 연구에서는 1970년부터 2002년까지의 시계열 자료를 이용하여 우리나라의 사회경제상황이 이혼율 증가에 어떤 영향을 미쳤는지를 분석하였다. Land and Felson(1976)의 거시 동태 사회지표 모형을 바탕으로 경제상황과 남녀 성비, 그리고 이혼 관련법의 개정 등을 분석모형에 포함시켰다. 경제상황에는 여성의 경제활동 참여율, 실업률 그리고 1인당 국내총생산으로 측정된 소득수준을 포함시켰다. 분석의 결과는 실업률과 소득수준이 이혼율의 증가 추이에 영향을 미치는 것으로 나타나고 있다. 1인당 국내총생산의 수준이 높을수록 이혼율도 증가하는 분석의 결과는 경제적 호황기에는 이혼율이 증가하고 경제적 쇠퇴기에는 이혼율이 감소한다는 선행연구의 주장을 실증적으로 뒷받침해주고 있다. 그러나 실업률이 증가할수록 이혼율도 높아지는 것으로 분석되고 있는데 이는 혼인의 결정 요인과 관련한 남성 중심의 가설을 뒷받침하고 있다. 이러한 연구의 결과는 경제상황을 구성하는 하위요인(소득수준과 실업률)이 이혼율의 변화에 미치는 영향의 기제가 다름을 보여주고 있다. 사회경제상황 자체보다는 경제상황의 변화가 이혼율의 변화에 어떤 영향을 미치는지를 분석하기 위하여 회귀분석의 모형에 변화율을 변수로 포함시킬 경우에는 1977년의 가족법 개정만이 이혼율의 변화율에 영향을 미치는 것으로 나타났다. 분석에서 이혼율에 영향을 미치는 모든 거시적 요인을 통제하지 못하고 있는데, 이는 이 연구의 내적 타당도를 저해하는 요인이 된다. 우리나라의 경우 이혼율은 경제적 상황보다는 오히려 문화적 또는 사회적 요인에 의해서 결정될 수도 있기 때문에 이혼율을 결정짓는 경제적, 문화적, 그리고 사회적 요인들을 모두 포함하는 분석 모형의 개발과 실증 자료를 이용한 검증은 향후의 연구 과제로 남는다.

Although the relationship between income and income inequality has previously been discussed, the present study applies a dynamic approach to analyze the specific relationship between forest household income and income inequality. For this analysis, a unit root test and a cointegration test were conducted to characterize the nature of income time-series data. After converting unstable time-series data into stable time-series data, a VAR model was estimated. Based on this model, an impulse-response was generated and variance-decomposition analysis was performed. These analyses showed that the effect of forest household income was relatively larger than that of the Gini coefficient, and that the impact of forest household income not only caused income to increase but also caused the Gini coefficient to decrease. In addition, the impact of the Gini coefficient had an impact on reducing forest household income and further increasing income inequality. We conclude that, with the aim of alleviating the inequality of forest household income, an income growth policy would be more effective than an income distribution policy.
