A considerable cost gap between three major power generation technologies, namely nuclear, coal, and combined cycle gas turbine (CCGT), has been a well-established fact in the Korean electricity market. Alternatively, this paper analyzes the levelized costs of electricity (LCOE) of the three technologies reflecting overall social costs of electricity generation including accident risk, $CO_2$ emission, and air pollution damage. The paper unveils to what extent current discriminative subsidies on fuels regarding the social costs, mostly through tax exemptions, affect economic competitiveness of the technologies. In particular, it finds relative positions of coal and CCGT could be altered depending on appreciation level of the social costs. It has limits in analyzing fixed costs of the technologies, however, due to limited data availability of nuclear power, and suggests further studies on the issue.

This paper investigates how economic freedom affected firm investment in Vietnam. In the globalization decade, economic freedom has been an important policy to support economic development in Vietnam. Improvements in economic freedom, such as capital freedom and domestic credit freedom, allow firms to access external finance more easily, so that the firm's investment depends less on internal cash flow. In a developing country, on the drawbacks, many small and medium firms likely have more challenges if the government would not give any subsidies. The higher level of freedom may exacerbate the financing constraints of less competitive firms. We analyze unique firm-level data from 2006 to 2016, which includes listed firms on two major stock exchanges and unlisted firms in the Unlisted Public Company Market. The article also considers how economic freedom affects small firms and large firms differently. Our results show that capital freedom and domestic credit freedom played an important role in investments for Vietnamese firms. However, we cannot find evidence that overall economic freedom relaxed the financial constraints on firms. Additionally, we suggest that small firms likely gain more advantage in access to external finance than do larger firms when the government removes restrictions from capital movement and the domestic credit market.

Korean population is ecpected to reach about 50 million by year 2000. And per capita GNP might attain the $5,000 level. This is bound to have profound impact on housing. For one thing, population and income growth will accelerate new household formation thus increasing new housing needs. On the other, changes in the housing preference function in association with income growth and new way of life would mean increasing demand for better dwelling environment. In addition, by year 2000, there will be many more elderly households necessitating new approaches to housing. The question is whether or not Korea could cope with new housing perspectives. If Korean housing has made in the past some progress in housing quality, it has not been able to tackle the mounting housing shortage. This is attributable to the concentration of effective housing demand in the hands of upper income groups in association with skewed income distribution and sustained dwelling price hike. Korea needs some basic changes in housing policy. The public sector should produce much more small dwellings either for sales or renting. Second, mortgage loans should be expanded so as to increase the access to housing. Third, every thing must be done to cut down the dwelling price through tax cut, relaxation of some requlations, cyclical stabilization of dwelling construction and loan subsidies.

Recently, environmental pollution related to global warming is on the rise. Meanwhile, renewable energy is a representative example of many efforts to develop eco-friendly energy to solve the depletion of natural resources and the depletion of petroleum resources in conjunction with global warming. Among them, photovoltaic power generation is increasing the subsidies for the government to increase the production of photovoltaic electricity of the general public, showing a high growth rate. However, polysilicon, which is a raw material of the photovoltaic panel, generates waste called polysilicon sludge in the manufacturing process. In order to produce 1 ton of polysilicon, about 2 tons of waste polysilicon sludge is generated. In 2012, polysilicon sludge was generated at 78,000 tons, with an average of about 220 tons per day. The sludge generated due to insufficient treatment of polysilicon sludge is currently solidified and is processed by landfilling. Therefore, in this study, polysilicone sludge is used as the concept of admixture, and the physical properties of the matrix according to the polysilicon sludge replacement ratio based on light burned magnesia is determined.

The COVID-19 pandemic is having an adverse impact on Bangladesh's economy by affecting millions of people's life and hampering their income sources. The outbreak of COVID-19 has created more pressure on the labor market. The pandemic reduces employment opportunities as most of the companies have stopped their recruitment process to cut their operational costs, which increases the rate of graduate unemployment in Bangladesh. Hence, this study aims to investigate the impact of COVID-19 on graduate employability in Bangladesh that adversely affects the income of families and eventually the nation's economy. A literature review has been conducted from secondary sources to evaluate the impact, which shows that the rate of graduate unemployment increased from 47% to 58% in 2020 with an expected annual loss estimated at $53 million. Findings also reveal that the prime reasons for graduate employability are low demand and huge supply of graduates in the labor market, lack of professional skills of graduates, ineffective education system, etc. The study suggests that the government of Bangladesh should develop some policies to overcome this problem such as ensuring employment subsidies, implementing skills development programs, improving labor market flexibility, initiating credit programs for generating employment, and developing entrepreneurial ecosystems in Bangladesh.

본 연구는 육아 인력 비용이 출산율에 미치는 영향을 국가별로 비교 분석하였다. 북유럽 국가들의 사례에서는 포괄적인 육아 지원 정책과 육아 인력 비용 지원이 출산율에 긍정적인 영향을 미치는 것으로 나타났다. 반면, 동아시아 국가들에서는 높은 육아 부담과 경제적 압박이 출산율 저하의 주요 원인으로 작용하였다. 개발도상국의 경우, 육아 지원 정책의 효과가 사회경제적 맥락에 따라 상이하게 나타났다. 본 연구는 육아 인력 비용이 출산율에 미치는 영향이 국가별로 다양한 양상을 보이며, 효과적인 육아 지원 정책을 위해서는 각국의 상황에 맞는 맞춤형 접근이 필요함을 시사한다. 향후 육아에 대한 사회적 투자 확대와 함께 돌봄의 가치를 존중하는 문화 확산이 요구된다.

The objectives of this study were 1) to review the current status of cooperative extension services in Japan, and 2) to draw implications for improving Korean agricultural extension system. Faced with various problems since its localization of extension services in 1997, Korean agricultural extension needs to be improved and strengthened in order to continually achieve the national goals of food production, balanced national development and preservation of environment, at the same time to meet increasing needs of farmers. The results of the study revealed the major characteristics of agricultural extension services in Japan as follows; 1) Each agricultural extension centers were administratively and technically coordinated by the prefectural (provincial) government, 2) There were 11 public corporations with agricultural extension functions under the MAFF(Ministry of Agricultural Forestry and Fisheries) financed by government subsidies 3) Agricultural experiment stations at provincial level were responsible for developing agricultural innovations for farmers' adoption, 4) The functions and operation of the agricultural extension centers were independent from the local agricultural administration. Some of the implications drawn from the study were as follows; 1) In order to accomplish major objectives of agricultural extension services in Korea legal status of agricultural extension centers should be changed from city/county to provincial government, 2) It would be desirable to establish public corporations concerned with agricultural extension under the Rural Development Administration, 3) Provincial Rural Development Administration should be reinforced in terms of applied farming research and diffusion of new technology, 4) Agricultural extension centers should be independent from administrative function and be separated from administration at the city/county level.

본 연구의 목적은 한국의 국가채무의 구성요소와 각 구성요소가 국가채무에 미치는 영향을 살펴보는데 있다. 통계청 국가통계포털에서 국가채무를 구성하는 요소로 일반회계 적자보전, 외환시장 안정용, 서민주거 안정용, 지방정부 순채무, 공적자금를 선정하여 검색하였다. 분석기간은 1997년부터 2019년까지 총 23개 연간자료를 이용하였다. 본 연구에서 정리한 자료는 각 구성요소별 전년대비 변동률을 이용하고 있다. 이를 이용하여 본 연구는 지표분석, 수치분석과 모형분석을 시도하였다. 상관분석결과 국가채무는 외환시장안정용, 공적자금 등, 서민주거안정용과 높은 관계를 보이고 있으나 지방정부순채무와는 무관한 관계로 나타났다. 국가채무는 지난 1997년 이후 외환시장안정용과 공적자금 등, 서민주거안정용과 동조화현상을 보이며 지속적으로 증가해 왔다. 2020년도 이후에는 코로나19로 인한 재난지원금 증가로 서민주거안정용과 공적자금 등에서 크게 증가할 것으로 예상되고 있다. 세계적으로 경제상황이 어려운 시점에서 우리나라도 국가재난 지원금의 사용으로 국가부채가 크게 증가할 것으로 보이지만 가능한 경제성장과 금융시장 안정을 위해 효율적으로 운용되기를 기대하고 있다.

본 연구는 창업벤처기업에 대한 수요 측 지원이 거시경제에 미치는 파급효과를 분석한 것이다. 분석모형은 Lucas(1978)의 기업가의 통제범위 모형을 준용한 동태일반균형모형을 활용하였다. 분석결과 창업벤처기업의 공공조달 비중을 5.7%에서 10%로 확대시켰을 때, 창업벤처기업의 실질생산이 약 46.17% 증가하고 벤처기업 수는 약 150%가 증가하는 것으로 분석되었다. 또한 벤처기업을 통한 일자리는 약 61.56% 증가하는 것으로 분석되었다. 그리고 공공조달 지원과 동일한 금액을 공급부문에 대한 지원금으로 창업벤처기업에 지원해 줄 경우 경제적 효과는 크게 줄어드는 것으로 나타났다. 이는 정부가 공급 측 지원 정책을 실시하면 공급 확대가 창업벤처기업제품의 가격 하락을 야기해 지원정책의 효과를 반감시키기 때문으로 풀이된다. 따라서 정부는 창업벤처기업 지원 시 공공조달을 통한 수요 측 지원을 확대하고 창업벤처기업에 대한 단순 지원금 지급을 축소함으로써 정책효과를 극대화 하려는 노력을 기울여야 할 것이다.
