USA has distinct differences of economic policy by a ruling party. And, USA economy has mainly influenced on it of Korea. So, we examine whether a ruling party of Korea has different regime including rate of return in stock market. The Republican Party and Democratic Party have based on Milton Friedman and Keynes economy at each other's economic policy in the USA The Republican Party and Democratic Party have different interest level and excess return on equity, GDP growth rate, unemployment rate. Also, a ruling party of Korea has different regime and economic activity in this paper.

The optimal choice of the tax rate and the inflation rate framework is extended to yield relevant interpretations for the optimal fiscal and monetary policy regime in Korea. To study the relationship between the government budget and monetary growth in different environments of policy coordination, two models assuming different degrees of fiscal dominance are developed. By modelling differing institutional arrangements of the fiscal and the monetary authority from an optimal government finance viewpoint, we find the optimal relationship among some important fiscal and monetary variables. By testing the existence of the relationship empirically, we find the characteristics of the optimal policy-mix regime in Korea. The first model-the strong from of fiscal dominance-studies the optimal collection of seigniorage in a period-by-period optimization with standard assumptions on the income velocity of money, deriving a general testable result: the optimal inflation/tax rate ratio co-vary with the marginal revenue ratio. The second model-the weak form of fiscal dominance-studies an implication of the inflationary bias of discretionary monetary policy in the presence of fiscal side distortions. This model shows that the tax rate and the inflation rate can have a positive correlation. Empirical tests of the theoretical results are done for the Korean economy for 1972-1989 period. The test results show that the macroeconomic policy regime in Korea can be characterized by the strong form of fiscal dominance, implying the importance of the government budget in explaining money growth and inflation.

This paper develops a simple theoretical model that is consistent with the empirical evidence of an inverted U-shpated relationship between pollution and per capita income, which is so-called environmental Kuznets curve in this literature. Also, by incorporating the issue of environmental externality into an endogenous growth model, I investigate the circumstances under which growth can be sustained with the optimal control of pollution, and hence the sustainable development can be achieved. In order to study the problem of implementing the social optimum in a market economy, I examine the optimality of three different kinds of environmental policy instruments; pollution tax, pollution-permit trading system (pollution voucher), and direct regulation. This paper shows that the optimum can be implemented with a pollution tax or with a voucher system. Also, it is shown that the socially optimal rate of pollution tax should increase proportionally to the growth rate of consumption.

우리나라에서는 70년대 중반 여후 공공요금관리(公共料金管理)가 물가정책의 주요수단으로 인식되어 왔으나, 다른 나라의 경험을 살펴보면 물가상승압력(物價上昇壓力)의 근본적인 해소가 전제되지 않는 가격규제정책(價格規制政策)은 유효한 물가대책(物價對策)이 아니라는 것이 보편적으로 인정되고 있다. 본고(本稿)의 분석(分析)에 의하면, 공공요금(公共料金)의 변동과 기타물가지수(소비자물가지수에서 공공요금 및 농축수산물지수를 제외한 것)의 변동간에는 장기적으로 같이 움직이는 공적분관계(共積分關係)가 존재한다. 그러나 일반의 인식과는 달리 공공요금의 변동이 기지물가변동(其地物價變動)을 초래하는 것이 아니라, 기타물가상승(其他物價上昇)이 공공요금상승을 유발하였던 것으로 나타났다. 이는 과거의 공공요금관리정책(公共料金管理政策)이 물가대책으로서의 유효성은 높지 않았음을 의미한다. 따라서 향후의 물가안정(物價安定)은 공공요금 등에 대한 직접적인 가격억제(價格抑制)보다는 경제전체의 물가상승압력(物價上昇壓力)을 완화시킬 수 있는 안정위주의 거시정책기조(巨視政策基調)를 통하여 이뤄 나가야 할 것이다.

This study aims to examine how the U.S. economic shocks affect the Japanese economy. It is widely believed that the U.S. economy has a significant effect on the Japanese economy. Actually, the U.S. accounts for a considerable amount of Japan's exports and imports. To the economic policymakers, it is very important to know how economic disturbances generated by the U.S. are transmitted to the Japanese economy. A vector autoregression(VAR) model is employed to investigate the international transmission channel of economic disturbances. The interactions of the U.S.-Japansese economy are investigated by using variance decompositions(VDCs). The results of this study provided the evidence that the U.S. economic shocks were important for the Japanese economy during the sample period. This study supports the notion of economic dependence of smaller open economy such as Japan as compared with larger economy such as the U.S.

최근 전력가격의 인상을 통한 전력수요 조절에 대한 관심이 높아지고 있다. 본고에서는 개방경제 CGE 모형을 통하여 전기요금 인상이 국민총생산, 물개 무역수지 등 주요 거시변수들에 미치는 영향과 개별 산업의 생산, 생산물 가격, 수출입에 미치는 영향을 분석하였다. 이를 위하여 1993년도 산업연관표에 기초하여 전체 산업을 16개 부분으로 통합, 재분류한 뒤, 전기요금 인상에 대한 다양한 정책실험을 시도하였다. 분석 결과 전력가격인상은 실질총생산의 감소 및 물가의 상승을 가져오나 그 정도는 기존의 연구보다 작은 것으로 나타났으며, 수출과 수입은 모두 감소하나 수출감소율이 수입감소율을 초과하여 무역수지는 악화되는 것으로 나타났다. 산업부문별로는 전기요금인상에 따라 비교역재에 가까운 서비스업의 생산량 감소효과가 두드러진 것으로 나타났다.

In this paper, we analyzed how oil price fluctuations affect stock price by industry using the non-parametric quantile causality test method. We used weekly data of WTI spot price, KOSPI index, and 22 industrial stock indices from January 1998 to April 2021. The empirical results show that the effect of changes in oil prices on the KOSPI index was not significant, which can be attributed to mixed responses of diverse stock prices in several industries included in the KOSPI index. Looking at the stock price response to oil price by industry, the 9 of 18 industries, including Cloth, Paper, and Medicine show a causality with oil prices, while 9 industries, including Food, Chemical, and Non-metal do not show a causal relationship. Four industries including Medicine and Communication (0.45~0.85), Cloth (0.15~0.45), and Construction (0.5~0.6) show causality with oil prices more than three quantiles consecutively. However, the quantiles in which causality appeared were different for each industry. From the result, we find that the effects of oil price on the stock prices differ significantly by industry, and even in one industry, and the response to oil price changes is different depending on the market situation. This suggests that the government's macroeconomic policies, such as industrial and employment policies, should be performed in consideration of the differences in the effects of oil price fluctuations by industry and market conditions. It also shows that investors have to rebalance their portfolio by industry when oil prices fluctuate.

통계학의 역사와 그 인식이 미천한 가운데 경제는 급속하게 성장하였고, 사회보장에 대한 기대의 추세는 급증하였으며 또한 산업사회로 급변하는 이 시대에 우리는 많은 정보에 직면하고 있다. 이렇게 다양하게 변해가는 과정에서 홍수같이 쏟아져 나오는 정보를 시시각각으로 정리하고 처리하여 나가야 하는 것이 또한 우리가 하여야할 과제인 것이다. 이상과 같이 거시적으로 전망할 때에 모든 분야에 많은 통계가 작성되지 않아 불편한 바가 적지 않음을 지적하지 않을 수 없다. 물론 박홍래 교수가 조사 발표한 바와 같이 245종의 통계가 작성되고는 있지만 이것만으로는 여러 분야의 통계가 부족한 실정에 있음을 우리는 직시해야 한다. 통계는 사회정책실시 이전에 필요한 것이 되어야 하기 때문에 한국과 같이 개발하여야 할 부문이 수다한 입장에서는 많은 통계수요가 절대적으로 요청되는 것은 쉽게 예견할 수 있는 것이다. 통계작성의 우선순위는 정책변수에 종속됨으로 정책변수의 중요도에 의하여 순차적으로 결정되어져야 한다고 볼 수 있다.

The purpose of this study is to estimate the macro-economic ripple effect of tax exemption for both high end technology firms and research enterprises in R&D special cluster. We apply the user cost of capital model and the Input-output model to the estimation. Estimation results for 2007-2016 are as follows: the increase in both the production and the value-added is 2,807 and 1,392 hundred million Korean won, respectively. Also, employers are increased by 2,355 people. These imply that keeping the tax exemption item for certain enterprises in R&D special cluster may be beneficial to our economy.

Now that fiscal soundness is increasingly important influenced by the euro area fiscal crisis, early budget execution has been under the spotlight as a tool for economy control, other than typical expansionary method, such as supplementary budget. Basically, early budget execution is a fiscal policy instrument that reponses to economic fluctuations through modifying the inter-temporal allocation of fiscal expenditure within budget, without affecting fiscal soundness. This study empirically examines how effective the intert-temporal reallocation of fiscal expenditure is in economy control. Using Korea's Consolidated Fiscal data, the size of inter-temporal reallocation of fiscal expenditure is defined as changes of fiscal expenditure for one year excluding seasonal factors and used to explain real economic growth rate, a dependent variable. The result shows that the macroeconomic effect of the inter-temporal reallocation turns out meaningful in general, though some policy time lag exists. Meanwhile, a simulation using macroeconomic model finds that overall effect on economic growth is not large because increase in fiscal expenditure allocation at a certain point of time is canceled by the opposite direction within the same fiscal year. However, the inter-temporal reallocation is found to reduce volatility of key macroeconomic variables so as to contribute to partially stabilizing macroeconomy. In particular, such effect of economic stabilization seems to be highly apparent at the time of financial crisis, but not very noticeable in normal economic cycle.
