This study is aimed to analyze problems of police budgetary execution and to suggest better ways for establishing effective budget implementation as well as legitimacy of securing budget in the field of police work. For this purpose, this paper analyzed the annual reports on police budgetary execution, from 2009 to 2012, conducted by National Assembly Budget Office. In result, most parts of the police budgetary execution were not satisfied with the audit standard, and especially in terms of management of budgetary execution, it showed 40% in inappropriateness. In addition, excessive and underestimate appropriation in the police budgetary execution, which happened frequently in other offices, was recorded on the second place. 10% of the amount of budget was executed for ordinance violence. Given results analyzed from each division, Transportation Division occupied 40% of the amount of related problems and all of types in the field did not meet the audit standard, thus it is required to manage budgetary execution effectively. In terms of Public Safety Division, the problem was related to budgetary allocation prior to execution, such as overlap in other works, excessive and underestimate appropriation, and inappropriate business plans. Director General for Planning and Coordination did not meet the standard of law system maintenance, Given the light of the result of analyzing programs, traffic safety and securing communication was the most problematic and support for police administration, crime prevention and protecting the disadvantaged, educating professional police officers, and establishment of policing infrastructure were required to be reformed in sequence. In order to resolve these problems, it is demanded to check budgetary execution and the process in business plans on a regular basis. Additionally, in case of using budget in inappropriate parts, tough penality including reduction of budget in related to the local police should be implemented to increase the importance of budgetary execution. Moreover, because of the fact that a part of problem of budgetary execution was originally caused by the budgetary allocation, it is advised to allocate police budget using the budget proposal of National Finance Act and Ministry of Strategy and Finance.

I build a small open economy (SOE) dynamic stochastic general equilibrium (DSGE) model to investigate the effect of a heterogeneous wage contract between regular and temporary workers on a macroeconomic volatility in a financially fragile economy. The imperfect financial market condition is captured by a quadratic financial adjustment cost for borrowing foreign assets, and the labor market friction is captured by a Nash bargaining process which is only available to the regular workers when they negotiate their wages with the firms while the temporary workers are given their wage which simply equals the marginal cost. As a result of impulse responsesto a domestic productivity shock, the higher elasticity of substitution between two types of workers and the lower weight on the regular workers in the firm's production process induce the higher volatilities in most variables. This is reasoned that the higher substitutability creates more volatile wage determination process while the lower share of the regular workers weakens their Nash bargaining power in the contract process.

As most of environmental impacts caused by development projects are irrevocable, a thorough review is utmost necessary. Ecological-economic integrated approach inspired by Norgaard's co-evolution theory should be applied to the environmentally adjusted CBA, which plays a decisive role in the feasibility analysis. Based on case studies of NamHan River Management Project and Yeongsangang Wetland Reclamation Project, this paper attempts to show the usefulness of linking basic plan and implimentation design to EIA and suggests to integrate EACBA into the current EIA system institutionally as a more effective policy tool for realizing sustainable development in Korea.

The Korean government adopted the integrated stream water management policy recently with growing perception that natural disasters and pollution in Korea have been due not only to such human factors as urbanization and industrialization, but also to the policy of functionally separated management of irrigation, flood control and ecological management. Contrary to its good intention, research result shows that it is not realistic to expect that this new integrated policy in Korea will work well. In order to be an effective policy and program evaluation, this paper suggests that evaluation indicator on related programs and projects should be made through bottom-up process. For example, environmental benefit should be taken into account rather than just economic benefit, and cultural and social characteristics in the project region should be also considered seriously.

디지털기술의 발전과 전송망의 광대역화에 따라 기존에 통신과 방송으로 각각 분리되었던 콘텐츠, 네트워크, 단말기 및 서비스의 경계가 허물어지는 융합화현상이 가속화되고 있다. 특히 방송분야와 통신분야의 경계가 모호해지며 통신과 방송 네트워크 및 서비스시장 간 융합현상이 나타나는 방송과 통신의 융합화, 즉 IPTV(Internet Protocol Television) 서비스는 대표적인 융합화의 큰 흐름을 보여주는 현상이다. 하지만, 지난 수년간 법적 제도적 장치를 마련하는 각 부처 및 산업내의 이해관계가 상충되면서 이러한 사회변화에 능동적으로 대처하지 못하고 있는 실정이다. 또한, 관련법 제정과 사업자 선정 이후에도 방송통신융합 산업이 활성화가 되기까지 많은 난관에 직면하고 있다. 이러한 맥락에서 본 논문에서는 방송통신융합(IPTV) 산업의 활성화를 위한 탐색적 연구를 통해 모색과 대안을 제시하고자 한다.

We studied the value of a nuclear power plant by considering Koreans' willingness to pay (WTP) for neutralizing the various problems caused by building and operating a new plant. For this, we used a conjoint analysis and ordered logistic regression. We then compared the WTP estimates between various segment groups. The results revealed that each household was willing to pay an additional 99,677 Korean Won (KRW)/mo on average to resolve the negative impacts from a nuclear plant. Therefore, the yearly cognitive and economic value of a nuclear plant in Korea was about 19 trillion KRW. Through a segment analysis, we found that the more educated, younger, and poorer groups gave higher cognitive values than the less educated, older, and richer groups, respectively. Also, people who lived far from a plant gave higher values than people living near a plant, and people with more knowledge about or interest in nuclear energy gave higher values than people with less knowledge or interest. People who felt that nuclear energy is necessary gave higher values to nuclear energy than those who did not. Our results can be used as bases to set targets for promoting nuclear energy and pursuing a national project of building a nuclear power plant.

The purpose of this study is to explore how health and health behavior factors moderate the relation between socio-economic position(SEP) and Korean elderly people's self-rated health status. The data sources are from the Korean Longitudinal Study of Aging(2008). The analysis sample consists of 4,040 cases. Analysis of the results shows that health characteristics such as ADL, MMSE, geriatric depression, and pain are significant predictors of self-rated health status. In addition, exercise and drinking alcohol also prove to be factors influencing self-rated health status. Health factor such as MMSE and health behavior factors such as drinking alcohol served as moderators of the influences of SEP on one's self-rated health status. For example, higher MMSE provides a slight increase to the positive relationship between SEP and self-rated health status. In addition, those who responded yes to drinking alcohol, compared to those who responded no, provides an increase to the positive relationship between SEP and one's self-rated health status.

This study tried to find out the level of national health expenditure and associated factors in the OECD countries and then to derive lessons for Korea's health financing based on the cross-national comparison. As a result, Korea's health expenditure in 2010(7.1% of GDP) accounted for 74.7 percent of the OECD average and ranked as countries to spend less on health. At the same time, the socio-economic indicators such as GDP per capita, elderly population ratio and the total tax revenue to GDP also remained between 72 ~ 82 percent of the OECD average. The public share of health financing(58.2%) was relatively lower than those of other countries. However the health expenditure and the public share have grown 1.9 ~ 2.4 times higher than the OECD average over the past decade. According to the quantitative analysis, countries with relatively high income and elderly population turned out to have high health expenditure. Whereas, an inverse relationship was found between the total health expenditure and the public funding. It was estimated that the value of national health expenditure to GDP decreases 0.083 when the rate of public funding increases 1 percent point. Further, the share of public funding was affected positively by the total tax burden. Based on these findings, this study suggests that the sustainable spending on health and alleviating households' direct burden could be ensured by enhancing the share of public funding along with adjusting the tax burden of the people.

The paper investigates the determinants of female, maternal, and male employment in a comparable setting using an unbalanced panel data of 29 OECD countries from 2000-2013. Our empirical results show that early childhood childcare and education (ECEC) is positively associated with female employment. Furthermore, we find that ECEC does not hurt male employment. We also find that tax rates on the second earner are negatively associated with male employment as well as female employment. The estimated coefficients of ECEC, social expenditure, tax rates, and tertiary education attainment rates in maternal employment regressions are much larger in the absolute value than those in female employment regressions. Policy implications of our analysis are that an expansion of ECEC, a lower tax on secondary earner, and education are key to promote the total employment as well as female employment.

In this paper, I examine the welfare effects of various revenue-neutral tax reforms in the case of two vertically-related oligopolies(downstream and upstream), where the upstream industry is polluting. I show analytically when and how government can improve welfare by initiating various tax reforms, regardless of either the feasibility of a lump sum transfer or the availability of a tax on pollution. The profit wedge that is the difference between the unit price and the unit cost and the marginal environmental damages(MED) becomes important to decidethe direction of a tax reform and is crucial to determine the direction of welfare-improving tax-subsidy schemes. I also show that a tax on pollution(Pigouvian tax) is superior to a tax on intermediate good even in the case of vertically-related oligopolies, because the former always brings in positive welfare effect from the upstream firms' input substitutability, which a tax on intermediate good cannot provide. Some policy implications for 'reducing environmentally-harmful subsidies' are also discussed.
