The research on the Factors affecting the quantity of automobile industry exported to USA

Korean automotive industry has occupied as a major industry and charged 3.3% of GDP, 7.3% of total employment in South Korea. Also it has become major export goods from korea to USA. However, in the US automotive market share was rated by nations as US 45.3%, Japan 37%, Germany 8.2%, south Korea 7.9%, others 1.5% in 2014. This shows Korean market share is much lower than that of Japan and US. The percentage of Korean automotive production in global market position decreased from 5.4% to 5.2% in 2012 to 2013. This decrease influenced adverse effect to export volume. For this reason, this thesis focused on the analysis of the determinants of influencing factor to export volume of automotive industry. Nevertheless, there is a limited literature on the influencing factors of automotive industry. This thesis, the analyze on inputs of GDP, exchange rate, oil price and strategic foreign direct investment, on the export of automotive industry to US. In addition, It derived the implication of automotive market based on the results.Ⅰ. 서 론 1 Ⅱ. 이론적 고찰 3 2.1 선행연구 3 2.2 시사점 4 Ⅲ. 한·미 자동차산업 현황 3.1 한국 자동차산업 현황 6 3.1.1 한국 자동차산업 수출입 현황 6 3.1.2 한국 완성차산업 현황 8 3.1.3 한국 자동차부품산업 현황 12 3.1.4 한국 자동차산업의 해외생산 및 대미 직접투자 현황 14 3.2 미국 자동차산업 현황 17 3.2.1 미국 완성차산업 현황 17 3.2.2 미국 자동차부품산업 현황 19 3.2.3 일본 자동차기업의 미국현지생산 현황 22 Ⅳ. 실증분석 4.1 연구방법 24 4.1.1 중력모형 24 4.1.2 회귀분석 25 4.2 분석모형 및 가설설정 26 4.2.1 분석모형 26 4.2.2 가설설정 27 4.3 자료구성 29 4.4 기초통계량 및 상관분석 31 4.5 추정결과 33 4.6 시사점 37 Ⅴ. 결론 39 참고문헌 4

Supply Chain Design and Carbon Penalty: Monopoly vs. Monopolistic Competition

This paper studies whether imposing carbon costs changes the supply chain structure and social welfare. We explore the problem from a central policymaker's perspective who wants to maximize social welfare. We consider two stakeholders, retailers, and consumers, who optimize their own objectives (i.e., profits and net utility) and three competitive settings (i.e., monopoly, monopolistic competition with symmetric market share, and monopolistic competition with asymmetric market share). For the monopoly case, we find that when the retailer's profit is high, imposing some carbon emission charges on the retailer and the consumers does not substantially change the supply chain structure or the social welfare. However, when the retailer's profit is low, imposing carbon costs optimally can lead to a significant increase in social welfare. Moreover, the impact of imposing carbon emission charges becomes more significant when the degree of competition increases. Additionally, the quantum of benefit may depend only on factors common across industries, such as fuel and carbon costs

Swapping inventory between competing firms

In this study, we investigate how competing firms swap inventory. We consider two firms located in two different markets that produce the same type of product. Each firm sells in the two markets. The selling price in each market is determined by the selling quantities of the two firms. We first show that the optimal swapping quantity is zero when firms decide to swap inventory without a sophisticated method. That is, they would not swap inventory. However, under our proposed inventory swapping method, competing firms swap a positive amount of inventory, enabling a higher profit for both firms. We also find that the swapped quantity increases as transportation costs decrease, and swapping inventory may not be beneficial if the transportation cost is either too low or too high. In addition, we investigate how to implement the swapping inventory agreement when the value of the swapped inventory differs by market. We show that firms may prefer to return the physical products to pay the value difference, especially if they are risk-averse. © 2018 Elsevier B.V

Inventory Sharing in the Presence of Commodity Markets

This study investigates the value of inventory sharing in the presence of spot and forward markets. We consider a multi-period setting where two firms process a common commodity to meet stochastic demands. They can buy and sell the commodity through both the spot and forward markets. They can also share the commodity if one has leftover inventory while the other has excess demand. We first characterize the equilibrium strategies of the two firms. Our analysis reveals that in such a context, the value of inventory sharing is low when the forward price is directly used to value the sharing transactions. We then develop a structured trans-shipment price scheme that uses a linear combination of the spot and forward prices. We show that this method can substantially increase the value of inventory sharing. Our analysis also reveals that in the presence of liquid spot and forward markets, the value of inventory sharing mainly results from the difference of the transaction costs, and it increases if the market in which firms operate becomes more competitive

Plant location and inventory level decisions in global supply chains: Evidence from Korean firms

We investigate how firms make plant location and inventory level decisions to serve global markets. In our analysis, we consider not only differences in wages, transportation costs, and subsidies across countries but also exchange rate changes and competition between firms. We show that the degree of risk exposure of firms and the benefit of relocating plants to the final consumption market play a critical role in firms’ plant location decisions, especially when the global economy is highly uncertain. We provide conditions under which a firm relocates its plant from one country to another, and empirically validate the results. We then investigate how a firm manages inventory when its plant is located in a foreign country. We model and show that firm's inventory level depends on currency exchange rates and transportation costs when the firm imports products. We empirically confirm the predictions of the theory by using a unique firm-level dataset drawn from Korean firms. © 2017 Elsevier B.V

An Outdoor Learning Model Through the Scientific Inquiry and Discussion Contest on the Subject for the Coronet Formation of Milk Drop

The '98 Scientific Inquiry and Discussion Contest organized by the Department of Physics Education has been performed for the subject analysing the coronet formation of milk drop. This study examined the feasibility to construct an outdoor learning model in the secondary or primary school, on the basis of the results of the '98 Scientific Inquiry and Discussion Contest. In this study, the hypotheses suggested by students who performed the inquiry contest were introduced. These explained how students approach the proposed problem. As outdoor learning models for the coronet formation by milk drop, the study suggested three types, such as 1) observation of the phenomena occurring in a very short time, 2) analysis of the phenomena by controlling external parameters, 3) understanding of the phenomena through model construction. These three types of inquiring approach may not apply to all levels of students equally. Thus this study suggest that teachers select an appropriate type of approach for their students.이 연구는 1998년도 서울대학교 사범대학 발전기금 연구비 지원에 의해 이루어진 것임

Acetone PLIF for Fuel Distribution Measurements in Liquid Phase LPG Injection Engine

Planar laser-induced fluorescence(PLIF) has been widely used to obtain two dimensional fuel distribution. Acetone PLIF is chosen because fluorescence signal from acetone as a fluorescent tracer is less sensitive to oxygen quenching than other dopants. Acetone PLIF is applied to measure quantitative air excess ratio distribution in an engine fueled with LPG. Acetone is excited by KrF excimer laser (248nm) and its fluorescence image is acquired by ICCD camera with a cut-off filter to suppress Mie scattering from the laser light. For the purpose of quantifying PLIF signal, an image processing method including the correction of laser sheet beam profile is suggested. Raw images are divided by each intensity of laser energy and profile of laser sheet beam. Inhomogeneous fluorescence images scaled with the reference data, which is taken by a calibration process, are converted to air excess ratio distribution. This investigation shows instantaneous quantitative measurement of planar air excess ratio distribution for gaseous fuel

The Educational Meaning of Scientific Discussion and Cooperative Inquiry Method in Physics Education Department

The Science Inquiry & Discussion Contest was held in 1993 as a part of The 1st Students' Scientific Inquiry Olympic. This contest was consisted of students cooperative inquiry and discussion in the form of game. The contest was successful and positively evaluated in science education, but it was originally designed for junior high school students. So we tried to apply the method of this event program(scientific discussion and cooperative inquiry) into curriculum of Physics Education Department in Seoul National University(SNU). The Science Inquiry & Discussion Contest was reorganized for undergraduate students and has been held since 1995 in Physics Education Department on SNU. All of undergraduate students and staffs in Physics Education Department participated in this program. In this report the results of 96 the Science Inquiry & Discussion Contest were introduced in detail with the evaluation and discussion. Through the application and evaluation of this program we came to get many positive implications. The first implication is that the cooperative inquiry with inter-grades students was possible. Second, the opportunity of long-term study was given to the students by this program. Third, Students could have chance to study in the different manner rather than those of classroom lecture style. And the last implication is that this program can be developed into a new style assessment of undergraduate physics education courses. In conclusion, the scientific discussion and cooperative inquiry method though The Science Inquiry & Discussion Contest had many positive results in undergraduate physics education curriculum, and such activities will be a kind of new style curriculum of undergraduate physics education courses.이 논문은 1996년 서울대학교 사범대학 발전기금의 지원에 의한 것임
