This paper has studied the monetary policy in Korea with a time varying VAR model using four key macroeconomic variables. First, inclusion of the exchange rate was a crucial factor in evaluating Korean monetary policy since the monetary policy demonstrated sensitivity to exchange rate movements during the crisis periods of both the Asian financial crisis of 1997 and the global financial crisis of 2008. Second, a specification of the stochastic volatilities in TVP-VAR model is important in explaining excessive movements of all variables in the sample. The overall moderation of variables in 2000s was more or less due to a reduction of the stochastic volatilities but also somewhat due to the macroeconomic fundamental structures captured by impulse response functons. Third, the degree of the monetary policy effectiveness of inflation was mitigated in recent periods but with increased persistence. Lastly, the monetary policy stance towards inflation stabilization has advanced ever since the inflation targeting scheme was adopted. However, there still seems to be a room for improvement in this aspect since the degree of the monetary policy stance towards inflation stabilization was relatively weaker than to output stabilization.

This paper attempts to search the driving forces of the Korean economy after 2000 by analyzing an estimated DSGE model and observing the degree of implementation regarding non-systematic parts of both the monetary and fiscal policy during the global financial crisis. Two types of trends, various cyclical factors and frictions are introduced in the model for an empirical analysis in which historical decompositions of key macro variables are quantitatively assessed after 2000. While the monetary policy during the global financial crisis have reacted systematically in accordance with the estimated Taylor rule relatively, the fiscal policy which was aggressively expansionary is not fully explained by the estimated fiscal rule but more by the large magnitude of non-systematic reaction.

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.

This study reviews theoretical considerations and past studies about real estate prices, macroeconomic variables, and real estate policies. Monthly data from January 2003 to June 2021 are used, and a VEC model, the most widely used multivariate time series analysis method, is employed for analysis. Through the model, the effects of macroeconomic variables and real estate regulatory policies on real estate prices in Seoul are analyzed. Findings are summarized as follows. First, macroeconomic variables such as money supply and interest rates do not have a significant impact on Seoul's apartment prices. Due to the high demand for housing and insufficient supply, there is a demand for buying a home regardless of macroeconomic booms or recessions. Second, tax and financial regulatory policies have an initial impact on the rise in apartment prices in Seoul, and their influence diminishes over time. Third, anti-speculation zones are expected to decrease apartment prices through the suppression of demand. However, these zones cause a rise in apartment prices. This could be understood as a lock-in effect due to the strengthening of capital gains tax. Fourth, the price ceiling did not decrease apartment prices. These findings propose that, in Seoul, where demand is high and supply is insufficient, the supply of high-quality and sufficient housing should be prioritized over various regulations such as tax regulations, financial regulations, anti-speculation zones, and price caps. Moreover, the findings provide an implication that city-specific real estate policies should be implemented for Seoul rather than regulation-oriented approaches in public policy.

향후 기후변화협약과 같은 환경규제의 강화가 예견되는 상황에서 에너지산업은 상당한 정책변화를 겪게 될 것으로 예상된다. 이러한 정책수립과 결정과정에서 본 연구는 천연가스산업에 대한 정책변화 효과를 분석할 수 있는 일반균형 분석모형을 제시함으로써 천연가스산업에 관한 유용한 정보를 제공할 수 있을 것으로 기대된다. 소국경제를 가정한 연산가능 일반균형모형(CGE)을 통해 분석된 천연가스산업의 거시경제적 파급효과를 살펴보면 다음과 같다. 먼저, 천연가스 가격이 5% 상승하였을 경우에는 실질GDP가 0.031% 감소하고, 생산자 물가지수는 0.051% 상승하였다. 가계수요가 10% 증가한 경우와 투자가 10% 증가한 경우에는 실질 GDP가 각각 0.002%씩 상승하고 생산자 물가지수는 0.008%와 0.004% 상승하는 것으로 나타났다. 이러한 분석결과는 천연가스산업이 비교적 거시경제에 미치는 영향이 적은 것을 보여 주고 있다.

This paper investigates the effectiveness of economic policy on the stock market in Korea around foreign currency crisis and stock market opening. For this purpose, the paper applied SUR technique to a set of monthly data over the period 1982.01 to 2004.12. The study finds the following results. First, for the entire sample period, Korean stock market appears to have effectively incorporated all of the past information about fiscal policy moves. However, the paper finds an evidence that some of the past monetary actions have significant impacts upon current stock returns implying that the information about past monetary moves has been overlooked. Second, there is an evidence to suggest that, after foreign currency crisis, the macro economic policy actions may influence stock market in a different way. In particular, after foreign currency crisis, monetary policy influences stock market in a more delayed pattern while past fiscal policy moves are well incorporated into current stock returns. Third, before stock market opening to foreign investors, some of the past economic policy actions have significant effects on current stock returns. On the contrary, after stock market opening, none of the past macro economic information has significant impact upon current stock returns. The results imply that stock market opening may contribute to the active utilization of economic information for market participants in Korea.

경제자유화(經濟自由化)와 규제완화(規制緩和)라는 세계적인 흐름과 함께 우리나라도 1992년 이후 자본시장(資本市場)을 점진적으로 개방(開放)하고 있다. 본 연구에서는 우선 몇몇 핵심 거시경제변수(巨視經濟變數)들의 상관관계(相關關係)가 자본거래의 자유화와 더불어 어떻게 변화할 것인가에 대한 이론적(理論的)인 배경(背景)을 설명하고 있다. 여기에서는 무엇보다도 자본자유화(資本自由化)와 더불어 나타나게 되는 실질환율체상(實質換率切上)및 경상수지적자(經常收支赤字)의 의미를 합리적인 경제주체들이 자원(資源)을 보다 효율적(效率的)으로 배분(配分)하고자 하는 노력의 결과로 나타나는 현상으로 파악하고 있다. 즉 자본시장의 개방은 상대적으로 높은 국내의 자본생산성 및 실질이자율을 향한 해외자본의 유입(자본수지(資本收支)의 흑자(黑字))을 초래하며, 대외부문의 항등식을 고려하는 한 이는 경상수지(經常收支)의 적자(赤字)로 연결된다. 또한 본 연구에서는 신고전파적(新古典派的) 장기모형(長期模型)과 케인즈적(的) 단기모형(短期模型)에 기초한 거시경제 모형을 구성하고 자본자유화(資本自由化)의 속도(速度), 환율(換率)및 통화정책(通貨政策)의 변화에 따른 거시경제의 동태적(動態的) 시간경로(時間經路)를 계량화하고자 노력하였다. 예를 들어 경상수지적자(經常收支赤字)의 폭은 자본자유화의 추진속도 및 거시정책에 의존할 것이나, 예상하지 못한 큰 충격이 도래하지 않는 경우 향후 2~3년간 GDP 대비 3% 내외에 이를 것으로 추정되며, 그 이후에는 실질이자율의 하락과 함께 적자폭도 축소될 것으로 나타나고 있다. 그리고 실질환율(實質換率)의 시간경로는 자본유입과 함께 지속적으로 절상될 수는 없으며 개방초기의 절상에 이어 점차 절하되는 추세에 놓이게 될 것이다. 자본시장의 개방에 따른 경상수지의 적자는 국내의 (실물)자본축적을 보다 용이하게 함으로써 실질이자율(實質利子率)을 하락(下落)시킬 것으로 기대되나 그 효과는 연 0.2%포인트 이내에 머무를 것으로 추정되었다. 아울러 자본자유화의 초기단계에 발생할 환율절상은 수출의 가격경쟁력을 약화시켜 단기적(短期的)으로 경기침체(景氣沈滯)를 유발할 수 있으나 중장기적(中長期的)으로 성장잠재력(成長潛在力)을 확충시킨다.

The macroeconomic concept represents the movement of a country's economy, and it affects the overall economic activities of business, government, and households. In the macroeconomy, by looking at changes in national income, inflation, unemployment, currency, interest rates, and raw materials, it is possible to understand the effects of economic actors' actions and interactions on the prices of products and services. The US Federal Reserve System (FED) is leading the world economy by offering various stimulus measures to overcome the corona economic recession. Although the stock price continued to decline on March 20, 2020 due to the current economic recession caused by the corona, the US S&P 500 index began rebounding after March 23 and to 3,694.62 as of December 15 due to quantitative easing, a powerful stimulus for the FED. Therefore, the FED's economic stimulus measures based on macroeconomic indicators are more influencing, rather than judging the stock price forecast from the corporate financial statements. Therefore, this study was conducted to reduce losses in stock investment and establish sound investment by analyzing the FED's economic stimulus measures and its effect on stock prices.

The emissions trading system stands as a pivotal climate policy in Korea, incentivizing abatement equivalent to 87% of total emissions (as of 2021). As the system likely has a far-reaching impact, it is crucial to understand how the real economic activity, energy sector, as well as environment would be influenced by its implementation. Employing a macroeconometric model, this paper is the first study analyzing the effects of the Korean emissions trading policy. It interconnects the Korean Standard Industrial Classification (Economy), Energy Balance (Energy), and National Inventory Report (Environment), enhancing its real-world explanatory power. We find that a 50% increase in emission permit price over four years results in a decrease in greenhouse gas emissions (-0.043%) and downward shifts in key macroeconomic variables, including real GDP (-0.058%), private consumption (-0.003%), and investment (-0.301%). The price increase in emission permit is deemed crucial for achieving greenhouse gas reduction targets. To mitigate transition risk associated with price shocks, revenue recycling using auction could ensure the sustainability of the economy. This study confirms the comparative advantage of expanded current transfers expenditure over corporate tax reduction, particularly from an economic growth perspective.

1990년대 중반을 넘어서면서 성장둔화에 직면한 한국경제의 애로요인으로 인건비, 토지가격, 금리 등 생산요소 가격의 상승, 기술개발의 부족 및 물류애로에 따른 과다한 물류비의 부담 등이 지적되고 있다. 이 세 가지 요인 중에서 생산요소가격의 문제는 거시경제정책의 변수의 성향을 가지고 있으며, 기술개발에 대한 투자와 결실은 단기(Short-Run)에 해결되기는 곤란하므로 개별기업은 물론 정부를 포함하는 제 경제주체의 노력에 따라서 물류비용을 획기적으로 절감하고 그를 통해 국가경쟁력의 회복 또는 강화의 계기를 발견하고자 하는 노력이 다각적으로 펼쳐지고 있다.
