U.S. monetary policy has been claimed to generate global spillover and to destabilize other small open economies. We analyze the effects of certain identified U.S. monetary shocks on gross capital flows in the Korean economy using the local projection method. Consistent with previous results on other small open economies, we initially confirm that U.S. interest rate hikes are dynamically correlated with foreign outflows and residents' inflows. That is, not only are they correlated with withdrawals by foreigners but they are also correlated with those by domestic (Korean) investors. The results are mostly driven by portfolio flows. Second, however, the marginal response to a U.S. monetary policy shock is, on average, subdued if we focus on the sample periods after the Global financial crisis of 2007-2008 (henceforth, global financial crisis). We conjecture a possible reason behind the change, an institutional change related to financial friction. If the degree of pledgeability of the value of net worth increases, the marginal responses by both investors would drop with a U.S. monetary policy shock, consistent with our findings.

본고는 소규모 개방경제를 상정한 동태확률모형을 통해 2000년 이후의 한국 거시경제의 변동요인들과 금융위기 기간의 통화정책과 재정정책의 변화요인을 추정하였다. 실증분석을 위해 동태확률모형은 경제성장률을 결정하는 두 가지 다른 추세요인과 다양한 구조충격요인 그리고 다양한 형태의 마찰을 포함시킴으로써, 거시변수들이 어떠한 요인에 의해 변화했는지를 정량적으로 분석하였다. 실증분석 결과, 금융위기 기간 동안 통화정책은 주로 테일러 준칙을 따른 것으로 나타난 반면, 재정정책의 반응은 재정준칙보다는 상대적으로 큰 폭의 재정충격요인에 의해서 설명된 것으로 추정되었다.

Recently, with the diffusion of a new paradigm named as the creative economy, the government's interests and efforts regarding support of SMEs' R&D have been concentrated. In particular, due to the dominant perception that the fundamental science and original technology from government-funded research institutes can further enhance the capabilities of SMEs' R&D, the importance of performance's diffusion on national R&D is further emphasized. In fact, the domestic SMEs don't have enough budget and workforce, so that all of self-contained technologies, product's competitiveness as well as the R&D capabilities, are very vulnerable, and thereby SMEs' commercialization is very likely to fail. For this end, SMEs need to adopt the concept of open innovation as the use of external R&D resources by licensing. In this study, we conducted a survey on a total of 286 domestic IT SMEs, and analyzed empirically to compare the degree of their acceptance on technological innovation between two groups divided by open/not-open innovation. As a result, we drew some of the key factors influencing the acceptance of the SMEs' open technological innovation, and found a variety of implications through them.

In this study, we identified the various mechanisms through which entrepreneurial orientation impacts firm performance. We proposed that entrepreneurial orientation assists organizations in building cultural, structural, human and technical knowledge capabilities, which in turn lead to sustainable competitive advantage. We tested our proposed hypothesis using data collected from 76 managers of small entrepreneurial firms. We found that cultural knowledge capabilities are the strongest mediators of entrepreneurial orientation and firm performance relationship. By bringing in knowledge capabilities in the literature of entrepreneurial orientation, we open new directions for research. Our findings have implications for theory as well as practice.

본 연구에서는 변동환율을 취하고 있는 small open economy 가 대외경제에 얼마나 긴밀하게 연결되어 있는가에 따라 그 경제의 환율이 어떻게 달리 반응하는가를 살폈다. 그 경제주체들은 대단히 효율적으로 필요한 정보를 활용해서 미래를 예측한다. 즉 이성적 기대(rational erpectation)를 갖는다고 가정한다. Small open economy의 환율을 분석한 기존의 모델들 대부분이 어떤 특정한 국제경제여건에 국한하여서 가능하면 단순한 모델들을 설정했기 때문에 그 결론들이 얼마나 광범위하게 다른 경우에도 유효한지 쉽게 알 수가 없다. 본 연구에선 점차적으로 현실적인 요소들을 모델에 가미해가고, 현대의 고도정보처리능력에 가장 적합한 기대형태인 이성적 기대를 다룸으로써 변동환율의 움직임에 어떤 일반성이 있을 수 있는가를 공부했다. 구체적으로, 제2장에는 국내경제가 국제경제와 구매력동등가설 (purchasing power parity)과 이자율동등가성(uncovered interest parity)로 긴밀히 연결되어 있는 경우를 살피고, 제3장에는 구매력동등가설은 적용되지 않고 이자율동등가설만 국내경제에 유효한 경우를 살폈다. 2장과 3장에서 국내투자자가 투자할 수 있는 금융자산은 통화와 국내.외 채권이며 주식시장은 고려되지 않았다. 4장에서는 상당히 자립적이고 현실적인 요소가 많이 반영된 경제를 분석하였다. 즉 국내경제가 국제경제와 구매동등가설이나 이자율동등가설로 직접적으로 연결되지 아니한 상황에서 주식을 포함한 모든 금융자산이 투자대상자산으로 가능하고, 또 환율의 변동이 재화의 국내가격에 반영되는데 어느 정도의 시차가 요구되는 경우를 살펴 보았다. 여기서는 내재변수의 수가 많은 관계로 numerical simulation을 이용했다. 본 연구의 결론 일부로서 첫째, 자국경제의 통화가 팽창되는 경우, 그 경제의 국제경제유착 정도에 상관없이 자국통화의 평가절하를 곧 유발하였다. 재정팽창의 경우에는 통화팽창의 경우처럼 환율의 방향에 대한 일반적인 결론을 얻지 못 했다. 둘째, 환율의 움직임에 대해 최근의 자산가격 모델(asset model)들은 과러 전통적인 Keynesian모델들과는 다른 설명을 하고 있는데 본 연구에서는 단기적으로 금융시장에서 자산의 수급일치가 균형조건으로 고려되고, 장기적으로 는 경상수지일치가 균형조건으로 포함되었다. 그 결과 장기균형을 예측하는 경제주체들의 기대가 현재환율의 움직임에 큰 영향력을 미침으로써, 전통적인 Keynesian모델들의 단기예측 유효성을 무시할 수 없음을 보였다. 세째, 개방된 경제에서 변동환율의 초기과민반응(overshooting)이 그것이 미칠 수 있는 왜곡된 signal효과 등으로 인해 상당히 염려. 논의되고 있는데, 본 연구 4장의 경제는 상당히 자립적이고 자국통화로 표시된 채권이 국제적으로 수용되지 않음에도 불구하고, 경제주체들이 이성적기대를 견지하는 한, 환율의 초기과민반응은 쉽게 관찰될 수 있었다. 넷째, 환율의 변동이 재화의 국내통화가격에 반영되는데 시차를 인정한 경우, 경제주체들이 이성적기대를 갖는한, 시차도입 후 뚜렷이 다른 경제양상을 보이지 않았다.

The purpose of this paper is to derive some policy implications on Korea's international education based on the research of America's experience of international education. The implications are summarized as follows. First, the main aim of Korea's international education should be on the increase of mutual understanding among world citizens, and also on the improvement of Korea's competitiveness. Since Korea is a small-open economy, she must find some policy methods to develop her economy continuously. Second, Korea should establish q private-run institution concentrated on the increase of mutual understanding of world citizens, like IIE in America. Third, Korea should also give Korea's universities some incentives to improve its own internationalization as well as to develop educational curriculum for teachers in international education.

This paper sets up a small open new Keynesian economy model with constrained households and incomplete markets to address the driving forces of business cycles in Korea. It shows that there exists a substantial fraction of constrained households who cannot have access to financial market. Furthermore, the estimated model reveals that a TANK model is better than a RANK model in explaining business cycles in Korea. The effect of domestic productivity shock on Korean economy has dominated in the variations of output, while the contribution of the foreign productivity shock to the variations of output and inflation has increased after the Asian financial crisis. The monetary policy shock has dominated the variation of inflation at short and medium horizons.

In 2011, the 4^th industrial revolution officially occurred and developed in most countries. The fourth industrial revolution has given organizations numerous business opportunities, enabling them to optimize their manufacturing processes, cut costs, and thereby improve their operations. The development of enterprises is a decisive factor in increasing national productivity, thereby improving economic growth and per capita income. Therefore, it is necessary to grasp the digital transformation plan and apply science and technology to domestic enterprises and improve the operational efficiency of the economy. Research on small and medium enterprises in Hanoi, Vietnam, which is considered a successful country in economic development and digital transformation and has become a middle-income economy and a highly open economy, the research results suggest that the ability to apply technology in businesses is capable of improving corporate financial performance. The choice of capital structure favoring debt has a negative effect on the financial performance of the enterprise; that is, enterprises in Vietnam should limit the choice of financing investment projects with debt, on the contrary, enterprises should choose to finance with equity. Finally, the study also discusses managerial implications for improving business performance in the context of the rapidly evolving 4.0 technology revolution.

Video Content owners seek to squeeze the maximum amount of revenue from their assets via distribution into more territories. Digital Cinema Package(DCP), trusted solution to distribute protected content to theaters, caters to relatively small user base, which limits revenue. With the growth of the Internet & other digital media, the economics of media content has changed dramatically. Security remains main concern to deliver content to millions of consumers using intelligent digital display devices like Tablets, Smartphones, Smart TVs, Desktop & Laptop. By making the video content available to this segment securely, content owners will benefit from increased revenue. Through this paper we propose Open Source HomeDCP model to distribute the content to home users for offline viewing. We propose to include other open source CODEC than JPEG2000/MPEG2, which are specifically designed for theatrical performance. Final image size will be further reduced considering the display device resolution where video will be finally played. Key Delivery Message(KDM) system to be altered to suit new devices. This will be a big boost to Content Economy as content owners would be able to distribute the content securely to the wider audience & ensure more revenue.

Purpose - The purpose of this paper is to seek some alternative to overcome difficult shipping situations for overcapacity pursuing economy of scale, which is widely spread in world shipping. Research design, data, and methodology - The research method to be adopted is first to review evolution of larger ships in terms of theoretical overview, and shipping market is examined, and it is studied some problems and solutions in relation to larger ship as field research aspects. Results - Supply and demand of shipping market is flexible and unpredictable nature of market. Sometime fierce competition has spread out the market, and shipowner may deploy mega ship in terms of economy of scale, etc., to overcome the difficult market situations. Both carrier and shipper have their own positions in this matter concerned. However, it causes some problems in the market including port matters, etc. Therefore, it is asked to solve this problems of larger ship employed in the markets, throughout shipping alliances, etc. Conclusions - Over tonnage done by larger ship has caused some problems in the shipping markets, forming monopolistic market by small number of larger shipping companies, destroying oligopolistic nature of shipping business, therefore, the answer is strategic alliance to collaborate each other.
