우리나라 도시근로자의 가계소득과 외식비는 함께 증가하고 있으나, 시간이 경과와 더불어 가계소득에 비해 외식비 증가율이 크게 둔화되고 있을 뿐만 아니라 가계소득에서 외식비가 차지하는 비율도 감소하고 있다. 이러한 외식비 지출패턴의 변화는 소득계층에 따라서도 달라 외식비가 가계소득에서 차지하는 비중은 2005년 이후 감소하나 10분위의 외식비 비중이 가장 낮고 1분위의 비중이 가장 높다는 것과, 외식비 비중의 표준편차도 소득계층이 높을수록 작고 소득계층이 낮을수록 크다는 것을 보인다. 외식비모형에 회귀분석을 적용하여 소득계수가 모두 유의하며 소득분위가 높을수록 계수의 크기가 작다는 것과 외환위기는 1분위와 10분위를 제외하고 음의 부호로 유의하다는 것을 밝힌다. 1분위와 2분위에서는 계절에 따른 외식비 변화가 없으며, 소득계층이 높을수록 계절에 따른 외식이 분명해진다는 것도 제시한다. 시간이 흐름에 따른 외식비 패턴의 변화를 살펴보기 위하여 전향적 이동회귀를 실시하여 단순 추정에 따른 것보다 훨씬 빠른 속도로 외식비의 소득탄력성 감소가 이루어지고 있다는 것을 밝힌다. 외식비를 분산분해하여 소득수준이 낮은 계층에서는 소득이 중요한 변수이나 소득수준이 높은 계층에서는 소득 이외의 요인들이 외식비에 많은 영향을 미친다는 것을 보인다.

Korean households' expenditures on foodservices are on the steady increase. This paper aims to examine the foodservice expenditures of salary and wage earners's households by income decile group. This is analysed through comparing foodservice expenditures with private education expenditures because households' expenditures are likely to be weighted in favor of eating-out rather than private education. We also model the consumption function in terms of income and price, examining the responsiveness of private education demand and eating-out demand to changes in income and price using econometric methods such as regression, rolling regression and impulse response. This paper show that foodservice demand increases more than the private education does in the long-run. The result indicates that households are likely to evaluate the desire for foodservice more important than private education contrary to our expectations in the long-run. The impulse response analysis, however, suggests that households tend to increase private education expenditures rather than eating-out expenditures in the short-run.

Background: Korea's primary care clinics are seeking increase in consultation fees by expanding supply within the frame of the health insurance system, but inequality of physician income between regions and individuals is exacerbating. The purpose of this study lies in analyzing the distribution of patients of primary care clinics, their specialized field, and the degree of inequality between medical fee income according to region. Data was acquired from the Health Insurance Review and Assessment Service on charged bills made by clinic-size medical institutions from 2008 to 2011. Methods: By comparing the outpatient number per clinic according to the clinic's specialized field, results showed that ophthalmology, otolaryngology, dermatology, orthopedics, and internal medicine showed high numbers whereas plastic surgery, neuropsychiatry, cardiothoracic surgery had fewer outpatients. The number of outpatients for clinic according to region showed Chuncheonnam-do, Jeju-do, Gangwon-do, Chungcheongbuk-do, Ulsan to have higher numbers of outpatients. For those four years, clinics in the Seoul area had a rather lower number. Results: As a result of comparing the decile hierarchy distribution ratio between specialized fields according to primary care clinics income from National Health Insurance, the inequality degree showed that obstetrics and gynecology and general medicine were each 0.130, 0.280 for the decile distribution ratio, which was the highest degree of inequality within the specialized field. Their Gini coefficient were also relatively high at 0.691, 0.528 respectively. On the other hand, the decile distribution ratio for otolaryngology and orthopedics were 0.510, 0.468, respectively, while their Gini coefficient each at 0.318, 0.314 makes their inequality degree relatively lower than other fields. Conclusion: This study is limited in that the data used was the health insurance charges submitted by clinics, which does not provide total information of the doctors' income. However, because most clinics are largely dependant on their income to come from health insurance reimbursements. Therefore, the results of this study can be used effectively. In the future, research that includes data on non-covered service income should be conducted to closely examine policy plans with a new medical fee policy which can resolve the medical fee income inequality issue between clinics as well as revitalize primary medical care.

This study collected and analyzed the datum related to consultation fee in National Health Insurance Corporation and characteristics of dental clinics for 819 dental clinics in Daegu and Kyungpook districts to specify the distribution and concentration rate of health insurance consultation fee and the critical elements of insurance consultation fee income. The average health insurance consultation fee per one dental clinics is 77.2 million won and the case of women dentists is 78.7 million won. That is higher than 79.9 million won that the case of man dentist. According to age, under 39 is 85.5 million won that is highest, declining little by little above 60s the number decreased to merely 23.9 million won. And the dentists whose business years from 5 to 10 are the highest and declining gradually. The more of engaging members to dental clinics is the larger the income. The average insurance consultation fee of Daegu province is 69.3 million won, but that of Kyungpook is 89.6 million won. Decile distribution ratio of dental clinics consultation fee income is 0.526 and Gini coefficient is 0.303. Decile distribution ratio of Daegu district is 0.489, Gini coefficient is 0.320. This explain the larger inequality compared with Kyungpook(0.623, 0.273). With age, Gini coefficient of below 39 is 0.260, the higher age is, the larger the number is, up to abode 60 the coefficient is 0.504, the degree of inequality is most extremely. insurance consultation fee and the number of cases of consultation is related to the age of dentists, duration of practice, the number of dentists and staffs engaging and provinces. That is, the lesser the age is, the longer the years of engaging are, the more the number of dentists and staffs we, the larger insurance consultation fee income and the number of cases of consultations we. And the fee fur one case is closely related to age and provinces. The fee for one case is higher in lower age, and that of in Daegu dental clinics is higher than in Kyungpook.

본 연구는 국가장학금제도가 반값등록금 지원이라는 소기의 정책목적을 달성하였는지를 분석해 보고, 이에 대한 개선방안을 제시하고자 하였다. 소득분위별로 등록금 경감률을 계산하여 실질적으로 반값등록금이 달성되었는지를 분석하는 방법론을 활용하였다. 연구결과 국가장학금 제도는 소득 2구간 이하의 학생들에게는 무상교육을, 6분위 이하의 학생들에게는 반값등록금을 지원하고 있는 것으로 나타났다. 이처럼 과반수의 학생들이 반값등록금 정책의 실질적인 혜택을 받고 있으나, 그 체감도가 떨어지는 것은 반값이라는 홍보성 구호가 국민들에게 각인되었기 때문이다. 따라서 본고에서는 이러한 인식차이를 좁힐 수 있는 홍보방식의 개선과 등록금을 단순지출이 아닌 투자의 개념으로 전환할 필요가 있다는 정책개선방안을 제시하였다. 또한 현행 무상지원 및 대출형 지원방식에서 벗어나 투자형 지원방식의 도입을 통해 학생과 정부의 부담을 동시에 최소화할 수 있는 방안도 검토하였다.

This study compared and analyzed the effect of income-redistribution, collecting data on the basis of the estimated details of insurance contribution and individual money wage lists for each one year before and after the combination of medical insurance program for industrial workers, by systematic sampling, extracting 4,160 families(14,764 people) among people applied to medical insurance program for self employees in Taegu City on the basis of Oct. 1st in 1998 with 227 associations of medical insurance program for self employees and medical insurance program for government employees and private school teachers combined, comparing the effect of income redistribution of before and after the combination of medical insurance program for self employees. The insurance contribution by household after the combination of medical insurance program for self employees showed the increase rate of average 20.9%, among them households of 68.8% increased and 31.2% decreased. The effect of income-redistribution was more positive because the degree of inequality was more deepened from 0.64 of the before-combination to 0.45 of the after-one in decile distribution ratio, from 0.26 to 0.34 in Gini -coefficient. Decile distribution ratio on the basis of insurance benefits by household was from 0.09 in the before-combination to 0.14 in the after-one, Gini-coefficient from 0.16 in the before-combination to 0.57 in the after-one was a little lowered. And decile distribution ratio of insurance benefits on the basis of insurance contribution was higher from 1.08 in the before-combination to 1.23 in the after-one, concentration index was a little lowered from 0.14 to 0.11, the effect of income-redistribution was improved in the phase of insurance benefits. The income-transfer rate of medical insurance program for self employees (the occupied rate of insurance benefits/ the occupied rate of insurance contribution) showed a lower trend in all of the before and after-combination towards upper classes, it was known that the income-transfer rate was higher from 1st degree to 7th degree in the after-combination in comparison with the before-one, but the effect of income¬redistribution was high because the income-transfer rate was lowered from 8th degree to 10th degree. The rate of medical insurance benefits (insurance benefits/ insurance contribution) increased from 0.79 in the before-combination to 1.07 in the after-one, and showed over 1.0 under 3th degree before the combination, but all of it was higher than 1.0 under 7th degree after the combination, the after-combination was more improved than the before-one in view of the rate of insurance benefits. As the result of above, on the basis of Oct. 1st in 1998 that 227 associations of medical insurance program for self employees was combined into one, we could say that the equality of imposing medical insurance contribution was more re-considered in the after-combination than in the before-one. But this study analyzed with classes divided, anyway, on the basis of insurance contribution, we have limit in explaining the correct effect of income-redistribution, because it was not analyzed according to classes of income, though it helps to analogize the effect of income-redistribution. So there must be analysis about the effect of income-redistribution, on the basis of the system, building up the system to grasp the correct income of the insureds of medical insurance program for self employees.

The National Health Insurance Expenditure has been increased rapidly since the introduction of the separation of prescription and dispensing in 2000, and this trend of rapid growth in overall spendings rate has been observed predominantly among medical practitioners. This study was conducted to investigate the growth rate and distributional changes in private medical practitioners' expenses from 1999 to 2002 and its determinants using the National Health Insurance claims data. The total increasing rate of all medical practitioners' expenditure paid by the National Health Insurance between 1999 and 2002 was $41.71\%$, which exceeding that of general hospitals by $20\%$p. But the income distribution among each practitioner was improved as the changes in Gini coefficient(from 0.40 to 0.38) and decile distribution ratio(from 0.25 to 0.29) during the same period showed. However, this improvement in distributional patterns is not enough since even in 2002 it turned out that the highest $10\%$ income group earned 33times more than the lowest $10\%$ income group did. Also, higher Gini coefficient was observed in larger cities and some department like plastic surgery, obstetrics and gynecology. The major causes of this differentials in medical practitioners' expenses were factors related to medical demand like proportion of old population, residential economic status in a given area. In addition, providers' economic incentives also played an important role in determining their income distribution. The large income differentials among physicians may imply a skewed distribution of patients and thus long waiting time, inefficient utilization of resources and potential inadequate quality of care. In this sense, unreasonable distributional gaps should be reduced, so effective measures as well as ongoing monitoring would be necessary to correct current distributional problems.

본 연구는 가계지출 부담을 주고 있는 사교육비의 증가원인을 여성 전업주부의 영향 관점에서 살펴보고 있다. 주요 결론으로는 첫째, 사교육비 정의를 세 가지 유형으로 나누어 효과를 살펴본 결과, 유형별 모형에 관계없이 여성전업주부는 가구의 사교육비를 증가시키는데 영향을 주고 있는 것으로 분석되었다. 둘째, 5분위 소득계층별로 구분하여 분석한 결과, 1분위를 제외하고는 2분위 이상 소득계층에서는 소득이 많을수록 가구의 교육비부담에 대한 전업주부 효과가 다소 줄어드는 것으로 나타났다. 셋째, 가구유형을 근로자 가구와 비근로자 가구로 구분하여 살펴본 결과, 사교육비 부담에 대한 전업주부 효과가 비근로자 가구보다 근로자 가구에서 더 강하게 나타났다. 이는 규칙적으로 소득을 벌어들이고 있는 근로자 가구가 비근로자 가구에 비해 전업주부를 통해서 사교육비에 더 많은 투자를 하기 때문이라고 볼 수 있다.

우리나라 신장암 발생을 소득 수준에 따라 확인하고 병기별로 분석하여 소득 수준에 따른 지연된 진단 정도의 차이를 확인하기 위하여 2015년부터 2017년까지 중앙암등록자료 및 국민건강보험공단, 건강보험심사평가원 데이터베이스를 연계하여 국가 단위 신장암 코호트를 구축하여 병기별, 소득수준별 신장암 발생률을 산출하였다. 연구 기간 중 우리나라 신장암 발생률은 모든 소득 분위에서 증가하나 의료보장인구에서만 감소하는 양상을 보였다. 신장암 발생률은 인구 10만 명 당 7.35 명이었고 이 중 83.54%가 국한 및 국소 신장암으로 소득 상위 20%에서 인구 10만 명 당 21.46명의 높은 발생률을 보였다. 그 중 국한 및 국소 신장암이 18.37명으로 소득 수준이 높을수록 국한 및 국소 신장암 발생률이 높은 것으로 확인된 반면 소득 수준이 낮을수록 원격 전이된 상태로 신장암을 진단받을 위험이 높음(소득 하위 20% adj.OR 1.807, 95% CI 1.411-2.222)을 확인하였고 의료보장인구에서는 병기 미상으로 진단받을 위험비가 1.926(95% CI 1.317, 2.816)으로 관찰되었다. 소득 수준이 높을수록 조기에 암을 진단하는 빈도가 높지만 소득 수준이 낮을수록 전이 신장암으로 진단받거나 병기 미상으로 진단받을 위험이 높아 소득 수준에 따른 건강 불평등이 관찰되었다.
