The purpose of this study was to examine the relationship between the child care support policies and the birth rate in 33 OECD countries. In the structural equation modelling, the birth rate was the dependent variable while the cash-support policies, the child-care facility service policies, and the tax benefits policies were the independent variables. The analysis showed that the most effective factor on the birth rate was the child-care facility service policies. Regarding the effectiveness of the policy expenses, the cash-support policies showed stable fluctuation of effectiveness according to the fluctuation of cash amount, the child-care facility service policies. In conclusion, in order to increase the effectiveness of the cash-support policies, the adequate cost calculation to decrease the parents' burden for child-bearing, re-allocation of budget, and support methods and timing should be continually discussed. In addition, for the better effectiveness of the facility service policies, more various, comprehensive and high-quality facility service policies that could balance home and work, should be implemented.

This paper studies how households who received Covid-19 transfers in cash used their one-time transfers. The transfers were paid in cash for welfare recipient households, which accounted for 12.9% of all households. Using a survey data, it is found that the cash transfers are mostly used for consumption expenditure, and 21.7 percent of the cash transfer used are spent on additional consumption not originally planned. The consumption response to cash transfers is greater in households that experienced job or income loss because of Covid-19.

본 논문에서는 온라인 전자현금 시스템을 설계하고 개발한다 개발된 전자현금 시스템은 공개키 알고리즘, 맹목 서명, tut-and-choose등과 같은 다양한 암호화 기법들이 사용되어 안전성을 높였으며 특히, 전자현금의 이중 사용(double spending)의 효과적인 방지를 위해 2중 은행 구조(2-level bank structure)를 취함으로써 통신망을 오가는 트래픽의 양을 많이 줄이고자 하였다. 이 구조의 가장 큰 특징을 각 은행마다 그 은행에서 발행하는 전자현금을 구분하기 위해서 전자 현금의 정보에 들어 있는 일련번호(sequence number)의 값을 은행별로 범주화한다는 점과, 이를 지원하기 위해서 각 은행마다 Cash Clearing Agent라는 모듈을 가진다는 점이다.

본 연구에서는 인터넷 기반의 전자 상거래에서 극소액 지불을 지원하고, 원격지에서의 계정 개설과 관리 등을 용이하게 할 수 있도록 지불인과 수취인을 쉽게 인증할 수 있는 인증이 강화된 전자 현금 모형의 지불 프로토콜을 개발하고, 프로토타입을 통해 그 효과성을 실험하였다. 또한 본 연구에서 개발하고자 하는 온라인 전자현금인 OnCash에서는 기존의 전자 현금인 Ecash나 Netcash와 마찬가지로 공개키 암호방식과 비밀키 암호방식을 이용하여 메시지 기밀성을 유지하고 전자 화폐의 이중사용을 방지하고, 적정한 수준의 익명성을 유지할 수 있도록 하였다.

본 논문은 5대 재벌 계열사들의 투자행태를 분석하였다. 5대 재벌 계열사들을 상장기업과 비 상장기업으로 나누어 분석하면 비상장기업의 투자는 내부현금흐름에 영향을 받고 상장기업에 비해 계열사 현금흐름에 영향을 받는 정도가 큰 것으로 나타나고 있다. 5대 재벌 계열사들을 종속기업과 비종속기업으로 나누어 분석하면 종속회사의 투자가 비종속회사에 비해 계열회사 현금흐름에 영향을 받는 정도가 큰 것으로 나타나고 없다. 본 논문의 분석결과는 5대 재벌의 경우 비상장회사와 종속회사가 다른 계열사들로부터 자금지원을 받는 형태로 내부금융시장이 작동하고 있다는 것을 보여주고 있다.

The National Basic Livelihood Security System implemented from October 2000 has expanded cash assistance to cover the poor households that have work ability. The cash assistance for the households with work ability has positive aspects of providing basic livelihood security for all people, but many people have worried about its negative aspects such as the decrease of labor supply among the low-income people with work ability. However, there has been few study that evaluated the effects of the NBLS implementation on labor supply. One of the reason for this may be related with the difficulty of research methodology that there were neither program group nor control group, because NBLS was implemented for all the people at the same time. This study suggests alternative program groups and control groups based on work ability and education. Using wave1 to wave5 data of the Korean Labor and Income Survey, this study estimated the effects of the NBLS implementation on employment and work hours. A difference-in-difference approach was applied to these alternative program and control groups. I found that the implementation of NBLS did not have any statistically significant effects on employment an work hours. It is too early to conclude from this result that cash assistance for the poor households with work ability does not induce any labor supply decrease in Korea. Rather, I interpret this result as reflecting that the NBLS system was too limited to induce any sizable decrease of labor supply or that the work requirement imposed on the recipients with work ability was effective in deterring work disincentive among the low-income population. Future research need to explore better program and control groups and investigate long-term effects.

The purpose of this study was to inquire into the formation and alteration of child care support policy and the actual of community based child care support policy in Japan in order to draw implications for child care policy in Korea. For the purpose of this study, the research contents are as follows. First, inquire into the formation and alteration of child care support policy. Second, inquire into the actual community based child care support policy. The major literatures reviewed were 'Child Rearing Visions' and 'Child Rearing New System'(The Cabinet Office, 2010) in Japan. For child care policy in Korea, two implications were drawn from community based child care support policy in Japan. First, it is necessary to establish macroscopic, comprehensive child care policy. And, the policy has to consider local finance and conditions of the community. Second, the child care budget based on liaison government and community should be expanded. Also, it has to provide child care support service through a community network.

Family policy focusing on family-work linkage is characterized by family policy measures which are made up benefits in cash, leave policies and social infrastructure for child care. This study aims to identify gender ideology of german family policy. Based on diverse indicators, this study is tried to analyze characteristics of benefits in cash, leave policies and social infrastructure for child care in Germany. And then, as the results of policy - implementation the fertility rate and women employment rate are presented. In Germany, family policies have been reformed in order to better support working parents. In spite of diverse endeavors, the results of this study show that german family policy has limits to family-work linkage. Family benefits in cash has had no effect on increase in fertility and women employment because of its traditional gender ideology. Leave policy and social infrastructure have to be improved for better provision of public chid care.

The purpose of this study was to examine the effects of child/family allowance on total fertility rate by period. For this purpose, it formed pooled-time series data from 1980 to 2015 targeting 19 OECD countries that adopted the child allowance policies, and made a close inquiry into a variable-based relationship through the pooled-time series cross-section analysis. The results were as follows. The child allowance appeared to have a significant impact on fertility rate even after controlling for other variables. Such impact was shown to be more noticeable in countries that introduced a fertility encouragement mechanism within its child allowance program. Based on the results, this study suggested the necessity of stepping up a benefit for multi-child families by additionally adopting a fertility encouragement mechanism within the child allowance program, in order for the child allowance program in Korea to function as well as the fertility rate promotion down the road.
