본 연구는 탄소세 부과가 우리 나라의 에너지 및 국민 경제에 미치는 충격의 영향분석을 목적으로 하고 있다. 이를 위해 에너지-경제 연계 계량경제모형을 수립하였는데 본 모형은 기존의 거시경제모형을 수정한 후 에너지 모형과의 연계를 통해 에너지 부문의 충격이 경제부문에 미치는 효과를 정량적으로 파악이 가능하도록 하였다. 본 연구에서는 탄소배출량에 대한 규제가 탄소세 부과를 도입하도록 유도하고 에너지가격의 상승과 에너지수요를 감소시킴으로써 경제부문의 생산을 위축시키는 흐름도를 가정하고 있다. 분석의 과정에서 탄소세 부과가 에너지 및 국민경제 부문에 미치는 효과의 측정은 에너지가격 및 수요변화, 국내총생산액의 변화 등을 통하여 수행되었다. 분석 결과를 요약하면 탄소 배출량의 안정화를 도모하기 위해서는 탄소세가 상당히 높게 부과되어야 하며 전력가격 및 에너지가격의 상승에 미치는 효과와 국내총생산액 등 주요 경제 변수에 미치는 충격이 매우 심각한 것으로 나타났다. 본 연구에서 개발된 계량경제모형을 통하여 여러 가지 정책수단에 대한 시뮬레이션이 가능하게 됨으로써 정책의 효과분석 및 동 분야의 향후 연구에도 많은 도움이 될 것으로 판단된다.

The objectives of this study is to assess the influence of individual characteristics and economic environment on the entrepreneurship such as entrepreneurial Intention and behavior based on the theory of Planned behaviors. This study used a country-level merged data set composed of GEM(Global Entrepreneurship Monitor) data and the OECD Statistics data. And this used the fixed effect model to analyze the panel data of 31 OECD countries during the period from 2005 to 2014. Our findings show that subjective norm has a significantly positive effect on entrepreneurial intention. In individual characteristics, the perceived opportunities has a significantly positive effect on early-stage entrepreneurial activity(TEA) and improvement-driven opportunity entrepreneurial activity. We identify the differences of between necessity-driven and improvement-driven opportunity entrepreneurial activity. For example, the effect on necessity-driven entrepreneurial activity is significantly negative. We also find the differences of between necessity-driven and improvement-driven opportunity entrepreneurial activity in economic environment variables. While real GDP growth as a demand variable has a significantly positive effect on necessity-driven entrepreneurial activity, unemployment rate as a supply variable has a significantly negative effect on early-stage entrepreneurial activity(TEA) and improvement-driven opportunity entrepreneurial activity. And GDP per capita as a supply variable has a significantly positive effect on early-stage entrepreneurial activity(TEA) and improvement-driven opportunity entrepreneurial activity. But the effect on necessity-driven entrepreneurial activity is significantly negative. We provide an interpretation of these empirical findings, emphasizing the importance of considering individual characteristics and economic environment simultaneously in promoting entrepreneurship.

The purpose of this study was to examine the effects of oral health behavior by oral health belief from the students in the dental hygienics department who take charge of oral health office, and therefore to lead a clear oral health care, to complete desirable oral health belief, and finally to utilize them for oral health field. The survey was conducted using structured self-administered questionnaires based on oral health belief model targeting 163 students in the dental hygienics department of one of the college in Seoul, and collected data were statistically analyzed using the SPSS 18.0 program. As a result of analysis to determine that the oral health belief significantly affects on the oral heal behavior, the personal variables such as age, economic status and occupation, and the seriousness for the oral health belief were indicated to be significant variables(p<0.05), and as a result of analysis that effects on the number of the oral health behavior, the susceptibility and the seriousness were indicated to be significant variables for oral health belief(P<0.05). As a conclusion, oral health belief was identified as a factor of salience through understanding that oral health belief of the students in the dental hygienics department effects on oral health behavior based on an oral health belief model, and it can be concluded that the necessity of oral health belief investigation should be discussed as a crucial issue to provide a more effective oral health promotion plan.

본 연구는 에너지정책을 종합적 차원에서 일반경제정책과 병행하여 정량적으로 분석할 수 있는 수리모형 (numerical multi-sector general equilibrium model)을 개발하기 위하여 시도되었다. 모형은 크게 (i) 가격/기술변화 반응적인 투입-산출계수를 내생화한 "산업간 거래모형 (inter-industry production model)", (ii) 민간에 의한 최종부문 수요를 나다내는 "소비자 선택모형 (consumer choices model)", 그리고 (iii) 생산물시장과 본원적 투입요소시장, 수출입시장 등에서 민간기업 정부 및 해외라는 개별 경제주체간의 행태를 반영하는 "거시경제 (성장) 모형 (macro-econometric growth model)"으로 구성되어 있다. 이러한 방법은 분석경제를 충분히 세분하고 제(諸)경제변수들의 동시결정적 과정을 중시한 일반균형적 /부문적 접근방법 (general equilibrium/sectoral approaches)을 취함으로써 지금까지 단순한 거시경제모형(aggregate macroeconomic models)이나 전통적 산업연관모형 (static input-output models)에만 의존해 오던 경제예측이나 경제 및 에너지관련 정책의 효과분석이 한층 더 강화될 수 있을 것으로 기대된다.

Estimated coefficients has serious problems including inconsistency, biasness, etc. because many researches about the effect of fiscal decentralization on a country's economic growth use the traditional OLS method. Researches use the data intactly so that so called "spurious regression" phenomenon exists. This causes fundamental fallacy. This research tries unit root test, cointegration test, and then estimates the United States' economic time series by using VECM. The analysis of the effect of the state level-fiscal decentralization on economic growth shows two long term-equilibriums. During short term-dynamic adjustment, fiscal decentralization and economic growth move the same or different directions. In case of prediction GDP increases steeply and then from 2015 gently; and fiscal decentralization index shows a general reduction trend and then decreases slowly. At local level it shows two long term-equilibriums. During short term-dynamic adjustment, fiscal decentralization and economic growth also move the same or different directions. Impulse response analysis shows the very negative effect of fiscal decentralization on economic growth.

The hypothesis that the common market equilibria for housing attributes are attained within distinctive submarkets was tested. Markets for housing attributes with greater supply flexibility, i.e., structural variables, were found to be closer to their common equilibria than markets with less supply flexibility, i.e., neighborhood and distance variables. In addition, submarkets with greater mobility were found to achieve common market equilibria for more housing attributes with greater supply flexibility, but not for housing attributes with lower degree of supply flexibility. Results suggest supply flexibility and occupier mobility are both necessary conditions for achieving common market equilibria for housing attributes.

This study is to evaluate whether economies of scale exist in four categories of university libraries in the Korea. Regression analysis is used to fit a log-log equation to the total budget-output (total circulation, interlibrary lending and borrowing, reference transactions, hours opened, volumes added, automation and information indicator) for all the types of libraries. In results of the analysis, returns to scale are almost constant in the national and public libraries and larger libraries. But there is presence of economics of scale in private libraries and all of the libraries. Except for hours opened, economies of scale decrease more rapidly.

Business entrepreneurs reflect their views of domestic and foreign economic activities on their operation for the growth of their business. The decision, forecasting, and planning based on their economic sentiment affect business operation such as production, investment, and hiring and consequently affect condition of national economy. Business survey index(BSI) is compiled to get the information of business entrepreneurs' economic sentiment for the analysis of business condition. BSI has been used as an important variable in the short-term forecasting models for business cycle analysis, especially during the the period of extreme business fluctuations. Recent financial crisis has arised extreme business fluctuations similar to those caused by currency crisis at the end of 1997, and brought back the importance of BSI as a variable for the economic forecasting. In this paper, the meaning of BSI as an economic sentiment index is reviewed and a GUIDE regression tree is constructed to find out the factors which affect on BSI. The result shows that the variables related to the stability of financial market such as kospi index(Korea composite stock price index) and exchange rate as well as manufacturing operation ratio and consumer goods sales are main factors which affect business entrepreneurs' economic sentiment.

This paper analyzes the effects of globalization on growth gaps between regions. Using openness and FDI as measures of globalzation in Korean 16 broad autonomous territories the study estimates the effects of the variables on growth gaps between regions. Estimation results show that FDI is significant in explaining the regional gaps while openness is not. The results of the study reveal that attracting FDI to weaker regions, especially the investment in New Industries, is inevitable to resolve growth gaps and for balanced growth among regions. Also, policy makers should use FDI as an important tool for correcting regional gaps as well as the vehicles for regional development.
