This study outlines measures related to fiscal policies aimed at responding to the financial crisis according to the timing of commencement and then examines impacts of expansionary fiscal policies on macro variables so as to extract policy implications. The size of expansionary fiscal policy to respond to the financial crisis is found to total 59.8 trillion won (6.1% of GDP in 2007), among which a total of 30.5 trillion won was the increased fiscal expenditure made by the 2008 supplementary budget, the 2009 revised budget and the 2009 supplementary budget. In addition, tax reductions are found to be a total of 29.3 trillion won, mainly driven by the tax reforms in 2008 and 2009. Examining dynamic changes in macro variables caused by the temporary increase in fiscal expenditure and the tax reductions reveals that the increase effect of the real GDP growth rate brought by a temporary rise in fiscal expenditure excluding tax reduction effects turned out to be 1.1%p in 2009 and 0.3%p in 2010, compared to the period without the increase in fiscal expenditure. Meanwhile, when taking into account the effect of expansionary fiscal policies including tax reduction effects, the increase effect of real GDP turns out to be much higher. In the case of 2009, the real GDP rose additionally by 1.9%p, in which 1.1%p by the increase in fiscal expenditure and 0.8%p by tax reduction. Based on these results, the expansionary fiscal policy conducted during the financial crisis since the second half of 2008 can be seen to have played a significant role in helping the Korean economy post a higher-than-anticipated recovery pace from the economic slowdown triggered by the crisis.

Baker et al. (Quarterly Journal of Economics, 134, 1593-1636, 2016) developed an Economic Policy Uncertainty (EPU) index for South Korea in the same way as the U.S. EPU Index. However, the South Korean EPU index of Baker et al. (2016) has limitations as it did not fully reflect South Korean situation in terms of keyword selection and the selection of newspapers. We develop monthly South Korean economic policy uncertainty indexes with different keywords and news media. Various analyses have been conducted in order to examine the usefulness of the newly compiled indexes.

This paper examines the evolution of the systems of innovation approach and its main issues. At first, national systems of innovation have appeared on the purpose to substitute the neoclassical macroeconomic policies. But various criticisms have been raised because of the restriction within national boundary of analysis, the lack of dynamic analysis, the danger of institutional determination, the deficiency of theoretical accuracy in national systems of innovation. Technological systems, regional systems of innovation, sectoral systems of innovation have been developed to overcome criticisms about national systems of innovation. Nevertheless the unsettled questions in the systems of innovation approach remain. The academic and policy-making usefulness of the systems of innovation approach will be expanded by development of the complementary researches within approach.

With the rise of China, the power and hegemony is moving to China in East Asia. The foreign policy of the China government is directly or indirectly affecting Korea, neighboring countries and the world. China is advocating a new international policy, a new security system, silk road policy and a new paradigm. China is a newly emerging powerful nation in Asia, and it is clear that China has the economic power to reestablish the Asian order and take over the hegemony. In addition, we want to run the world supremacy with the United States in political, economic, military and diplomatic sectors. In order to overcome the crisis of the Korean peninsula, which is being triggered by North Korea's nuclear and missile development, we are in the position to do our best to cooperate with Korea, the United States and Japan and further improve relations with China. In this study, I analyzed the policy of Southeast Asia and China macroscopically.

실제(實際)GDP와 잠재(潛在)GDP의 차이로 정의되는 GDP갭의 변화는 경기변동(景氣變動)을 반영하는 동시에 실물경제의 흐름과 물가압력을 연계하는 거시경제변수라고 할 수 있다. 그러나 통상적인 의미의 GDP갭은 경기변동의 근원적(根源的) 요인(要因)(sources of business cycle) 에 대한 설명력이 결여되어 있음을 감안하여 본고(本稿)에서는 주로 경제의 총수요(總需要) 측면에 초점을 맞추어 GDP갭을 추정하였다. 추정된 GDP갭의 변화패턴이 경기변동의 정점(頂點)및 저점(底點)과 거의 일치(一致)하는 동시에 과거 경제운영 과정에서의 주요 정책변화(政策變化)와 일관성(一貫性)을 보이고 있어 현실경제에 대한 설명력이 높은 것으로 평가(評價)된다. 또한 추정된 GDP갭은 수요봉인(需要奉引)에 의한 물가상승(物價上昇)과 밀접하게 연계되어 있으며, 총통화(總通貨) 및 금리(金利)의 변화(變化)와도 높은 상관관계를 나타내고 있다. 경기변동(景氣變動)의 요인(要因)을 수요(需要)측면과 공급(供給)측면으로 구분하여 살펴본 결과 수요변화는 단기적인 성장효과에도 불구하고 장기적(長期的)으로는 물가(物價)에 보다 큰 영향을 미치고 있는 반면, 공급측면의 변화는 장단기(長短期) 모두에 있어서 성장(成長)과 물가(物價)에 지속적인 영향을 미치는 것으로 추정되었다. 또한 물가안정을 위한 총수요긴축(總需要緊縮)에 수반되는 단기적인 성장둔화(成長鈍化) 효과가 상대적으로 큰 것으로 나타나고 있으며, 우리 경제의 높은 해외의존도(海外依存度)로 인하여 해외(海外)로부터의 공급충격에 따른 실물부문(實物部門)의 경기변동이 적지 않았다는 결과가 도출되었다. 이러한 실증분석 결과의 시사점은 (1) 물가안정에 수반되는 경제적(經濟的) 비용(費用)이 크므로 처음부터 물가압력(物價壓力)이 확대되지 않도록 경제(經濟)를 안정적(安定的)으로 운영하는 것이 바람직하며, (2) 자본자유화(資本自由化) 등의 진전으로 실물부문뿐만 아니라 금융부문(金融部門)도 해외(海外)로부터의 공급충격에 직면하게 될 것으로 예상되므로 임금(賃金) 등의 요소비용(要素費用) 안정과 함께 구조조정(構造調整) 및 경쟁(競爭) 촉진(促進) 등을 통하여 경제의 체질(體質)을 개선(改善)하는 노력이 요구된다는 것으로 요약할 수 있다.

This research is to examine the impacts of the on-going global financial crisis on the housing systems of welfare states. Four developed economies in the Western Europe were selected for the analysis, and the qualitative research employed in-depth interviews with scholars in the fields of housing market and social policy in order to meet the research goal. The major findings indicate that the global economic crisis embedded into the liberalization of housing finance and the inadequacy of regulatory measures caused the vicissitude of housing markets, and its scale and magnitude could be determined by the resilience of each state's housing system. While the globalization of housing finance markets rendered easy borrowing for homeownership, intensive competition for excessive lending among financial institutions backed by heavy reliance on inter-bank and overall bank triggered market volatility, and further worsened household and public debts. It's clearly evident that a housing system with varied safety nets becomes a greater cushion to bear the risks of the financial crisis and to weather the economic storm.

최근 국내 실물경기는 수출 부진이 지속되는 가운데 건설투자 중심으로 내수가 완만하게 증가하는 추이를 보이고 있다. 내수는 설비투자가 부진한 반면 건설투자가 높은 증가세를 보이면서 전체 성장을 주도하고 있고, 민간소비는 완만한 증가세를 지속하고 있다. 수출은 전년에 이어 감소세가 지속 중이나, 금년들어 감소폭이 줄어들고 있다. 전체적으로 수출 부진에 따른 성장 둔화를 건설투자가 보전하는 구조로, 경제성장의 건설투자 의존이 심화되는 특징을 보이고 있다. 2017년 세계경제는 완만한 회복세가 이어지면서 전년보다 소폭 높은 성장을 보일 것으로 예상된다. 선진권의 경우 비교적 꾸준하고 완만한 성장세가 이어질 것이나, 중국은 완만한 성장 둔화 추이가 이어질 전망이다. 유가는 세계경제의 소폭 개선과 OPEC의 감산 합의 등으로 2017년 중 평균 배럴당 50달러 내외로 높아질 전망이며, 원/달러 환율은 연중 비교적 높은 변동성을 보이겠지만, 연평균 기준으로 전년과 비슷한 수준(1,150원대)이 예상된다. 2017년 국내경제는 수출 부진이 다소 완화되겠지만, 2016년 경제성장을 견인해 온 건설투자 증가세가 크게 둔화되고 구조조정 등이 민간소비 증가를 제약하면서 전년보다 약간 낮은 2.5% 내외 성장을 보일 것으로 예상된다. 전기비로는 상${\cdot}$하반기 비슷한 성장이 예상되지만, 전년 패턴의 기저효과로 전년동기비 성장률은 소폭의 上低下高 흐름이 예상된다. 대외적으로는 미국 신정부의 정책 기조와 연준의 금리인상, 중국의 성장 둔화 폭 확대 가능성 등이, 국내적으로는 가계부채 문제와 구조조정 여파 등이 주요 변수로 작용할 전망이다. 부문별로 살펴보면 민간소비는 유가 반등에 따른 소득 증가세 둔화, 가계부채 부담, 구조조정 여파 등이 제약요인으로 작용하면서 전년보다 소폭 낮은 연간 2% 내외의 증가세가 예상된다. 설비투자는 수출 부진의 완화에 힘입어 소폭 증가세가 예상되며, 건설투자는 전년의 높은 증가에 따른 기저효과와 건설규제 등에 따라 증가세가 크게 둔화될 전망이다. 수출은 세계경제의 소폭 개선과 유가 반등에 따른 단가 하락세 진정 등으로 증가세로 돌아설 것이나, 매우 완만한 흐름이 예상된다. 2017년 수출은 2.1%, 수입은 3.6% 증가하면서 무역수지는 전년보다 약간 줄어든 857억 달러의 흑자를 보일 전망이다.

Global warming and a new energy policy request the energy saving and pollutant emission control in municipal level. Previous studies focus on transportation in the Seoul metropolitan area which can easily meet the policy goal by reducing it. This study expands the area of urban energy planning to the industries and land use which takes up most of energy use of the city. We empirically study the Busan metropolitan area's 5 years natural gas and electricity consumption data by the industries and land use. Results show that energy usage significantly depends on not only population but also urbanizing intensity and industrial category. This paper address that the policy maker need to pay attention on energy usage pattern of each sectors during the planning.

This paper aims to derive macroeconomic implications by analyzing the business cycle characteristics of the youth unemployment. The results of empirical analysis seem to show that youth unemployment appears to be relatively less correlated with business cycle compared to other age groups, and thus it is difficult to explain the recent steady increase in the potential labor force as a result of the business cycle fluctuation alone. Moreover, the alternative unemployment measures of the youth group showing upward trend were estimated to be co-integrated with output measures. This co-integrated trend increase suggests that unlike other age groups, youth may be influenced by structural factors inherent in Korea's economic growth path. The fact that the wage difference based on firm size has widened steadily since the Asian financial crisis and that the proportion of large companies that provide relatively high-quality jobs compared to major industrialized countries is significantly lower may be the evidence of the structural changes in Korean youth labor market. The results of above analysis may explain why the job search periods for youth has lengthened amid these structural changes.

The covered interest rate parity condition (CIRP) has been widely used in open macroeconomic analysis, risk management, exchange rate forecasts, and so forth. Due to the recent global financial crises, there have been remarkable changes in the financial markets of the emerging markets. These changes possibly influenced the dynamics of the covered interest rate parity condition. In this paper, we investigate whether the CIRP dynamics has changed, and what is the nature of the regime changes. To do this, we propose and estimate multiple-state Markov regime switching models using a Bayesian MCMC method. Our estimation results indicate that the default risk or the deviation from the CIRP has been decreased after the crisis. It seems to be associated with the more active interaction between the short-term bond market and the short-term foreign exchange market than before. The tightened relation of these two financial markets is caused by the arbitrage transaction of foreign investors.
