The objective of this study is to examine the trend of real earnings for TANF leavers. Using administrative data in Wisconsin, this study tracks the 1998 TANF leavers over 7 years. Based on the cyclicality of real wage hypothesis, this study finds: First, although the average real quarterly earnings of TANF leavers have remained stable since their exits, there are substantial labor mobility among TANF leavers. Second, the panel data analysis shows that the real earnings of TANF leavers are significantly associated with local labor market conditions, which supports the hypothesis on the cyclicality of real wages. This study has policy implications that labor market conditions matter for the economic well-being of TANF leavers and the labor demand policies are needed for the economic security of TANF leavers after the exit.

This study investigates the difference in income trajectories of the working poor and the non-working poor and explains the effects of socio-demographic (marriage, education) and regional (living in large cities) factors on intergroup differences. We use Seoul Survey data collected between 2009-2018 and the latent growth modeling approach. It was found that the trajectory difference between groups was statistically significant. Since 2016, the income gap widened as the income of the working poor stagnated. The three variables included in this model better explained the income trajectory of the working poor compared to the working non-poor. In particular, the change in income growth rate was positively related to whether they live in large cities. This suggests the possibility that living in a large city would act as an economic premium for the working poor. It is necessary to conduct follow-up studies on urban premiums for the working poor.

근로자들의 소득을 두고 흔히 '유리지갑'이라고 한다. 그만큼 근로자들의 소득은 그 흐름을 쉽게 알 수 있고 편한 과세대상이다. 회사가 급여를 지급할 때 근로자를 대신해 세금을 징수.납부하고 1년에 한 번씩 근로자의 1년 총소득(세법상 근로 소득으로 구분된 소득)에서 기초생활비에 해당하는 소득을 과세대상에서 제외시켜 과도하게 납부한 세금이 있을 경우 나라를 대신해 돌려주거나, 추가로 세금을 징수해 납부하기도 한다. 이런 절차를 근로소득세 연말정산이라고 한다. 사례를 통해 연말정산 때 혼동하기 쉬운 공제여부에 대해 알아보자.

This paper compares the earnings effect of inter-industry technology differences between the self-employed and wage earners. It is assumed that primary skills utilized by the self-employed and paid workers differ in nature, and thus the earnings effect of technology differences and its skill-biasness also differ for each type of workers. For the empirical analysis. Heckman's two-stage method and quantile regressions are fitted to Korean panel data. The earnings effect of technology differences turns skill- biased for wage earners (job-specific skills), but prevails for all self-employed workers (entrepreneurial skills) regardless of their schooling level. This sectoral difference holds for each different quantile of earnings distribution.

2009년부터 도입된 근로소득 장려세제(EITC)와 가장 밀접한 관계가 있을 것으로 예상되는 기초생활 보장제도를 고려하고 근로소득 장려세제의 수급요건에 적합한 수급 세대규모와 상관분석 등을 통해 영향 요소를 선정하고 영향 요소를 예측하여 향후 근로소득 장려세제의 수급 규모나 필요 예산을 예측할 수 있는 시스템을 개발하였다. 예측에는 시계열 분석과 사회제도 성장에 적합한 로지스틱곡선 등을 이용하였다. 본 연구에서 제안된 시스템은 향후 제도에 따른 사회적 영향 예측과 제도 개선에 필요한 의사결정을 전략적으로 지원할 수 있을 것으로 기대한다.

Self-employment rate is high in Korean labor market, while the income gap within self-employed is also high. Although, there are very few studies that addressed on the income inequality of self-employed. Thus, this study has measured the earnings inequality of self-employed by generalized entropy indices and decomposed inequality factor and trend. The empirical study is based on Korea Welfare Panel Study wave 1~4. The main result from this analysis is summarized in three points. Firstly, earnings inequality of self-employed is severely high and the earnings polarization within self-employed has become more serious in Korea. Secondly, this study provides the evidence that the main factor of earnings inequality of self-employed is the status of self-employment, education level, age group, workplace scale and industry. Thirdly, the contribution of relative changes in the incomes of the status of self-employment is the largest to the inequality trend. In terms of education level, age group and industry, the increase of inequality within group(pure effect) mainly attributes to the rise of earnings inequality of self-employed and the change effect of group composition contributes to deterioration of inequality.

Using matching and difference-in-differences estimation method, this study estimates causal effects of health shocks on employment and income of full-time workers aged 40-55. Acute hospital admissions lower significantly the employment probability and earnings. The changes in employment and earnings persist up to three years after the health shock. The economic impacts of health shocks vary by socioeconomic status and job characteristics among individuals. Irregular workers are more likely to leave their jobs after health shocks than regular workers. Among irregular workers, the probability of leaving labor market after health shock decreases with the size of the firm.

This study is intended to explore an income level necessart for the old-age by income Status. Firstly, it is verified whether there is significant difference between old-age and working age or not. Secondly, if their difference is found, it will be identified that it is determined by certain factors. Thirdly, it is brought out needful income level for the old-age living through analysing old-age consumption expenditure level over working age. The results in this research are as follows. Firstly, there is a significant difference between old-age and working age. Secondly, the major factors which generated difference between old-age and working age consumption expenditure are income, household size, and age. Thirdly, the income level necessary for oldage living is on average 61 %. By income status, it is 90-100% for low income status, 60-70% for middle income status, 50-60% for high income status.

This study focuses on how the recognition of year-end-settlement affected on the effectiveness of individual tax return according to the tax law and its influence on the participation of employee. After the careful analysis, the founding of the satisfaction level of workers from the annual tax return can be summarized as follows: When the knowledge of year-end-settlement is high, it influences positively on the effectiveness of tax return for workers. The recognition of tax return system is the main ingredient to increase the participation of the tax return. Although the recognition of year-end-settlement did not affect on the satisfaction of workers directly, effectiveness of tax deduction and the participation in the year-end-settlement are closely linked to the satisfaction level of tax return, It is confirmed that when the recognition of year-end-settlement is high. the more people actively participate in year-end-settlement and it contribute to the positive effect on the satisfaction level of employee, As a result, it is very important to find the ways to promote and educate annual tax return system to workers as well as revise the tax law to maximize the year-end-settlement for employee.

본(本) 연구(硏究)에서는 1984년 한 해의 "도시가계연보(都市家計年報)"(전산(電算)테이프자료(資料))를 이용해 도시가구(都市家口) 계층간(階層間) 및 계층내(階層內)의 소득(所得) 및 소비(消費) 후생불평등도(厚生不平等度)를 추정하였으며 그 요인(要因)을 근로소득(勤勞所得)의 측면(側面)에서나 찾아보았다. 본(本) 연구(硏究)의 주요실증분석(主要實證分析) 결과(結果)는 다음과 같다. (1)도시가구(都市家口)의 불평등(不平等)을 크게 좌우(左右)하는 것은 재산소득(財産所得) 유무(有無)이며 (2)근로소득(勤勞所得)의 불평등(不平等)은 주로 학력간(學歷間) 임금격차(賃金格差)에서 비롯되고 있으며 (3)재산소득(財産所得)의 불평등(不平等)은 자본이득(資本利得)(capital gain)을 좌우(左右)하는 일반물가수준(一般物價水準)의 불안정(不安定)에서 비롯되고 있다. 따라서 불평등(不平等)의 개선(改善)을 위해서는 무엇보다도 먼저 물가수준(物價水準)의 안정(安定)이 최우선 조건이며 이와 더불어 학력간(學歷間) 임금격차(賃金格差)를 완화(緩和)시키는 노력도 병행되어야 할 것으로 보인다.
