This study aims is to determine the factors that influence Indonesian rubber export supply based on the export destination countries. Indonesian rubber export supply is thought to be influenced by the variables like the volume of Indonesia rubber exports, the price of Indonesian natural rubber, the volume of domestic rubber production, the export volume of the previous period, the rupiah exchange rate against US$, the interest rate and real Gross Domestic Product (GDP). The data used is the annual time series from 1995-2015 based on export countries encompassing the United States, China, and Japan. Multiple linear regression with the Ordinary Least Square (OLS) method is applied to analyse the data. The results showed that the volume of Indonesian rubber exports to China is not influenced by domestic natural rubber prices and the Rupiah exchange rate against the Chinese Yuan. The volume of Indonesian rubber exports to Japan is influenced by the volume of domestic rubber production. The volume of Indonesian rubber exports to the three destination countries is influenced by the volume of domestic rubber production, interest rate, and real GDP.

Since 1988 the fur fashion industry in Korea has been difficult in exporting and competition with too many brands after opening the dom-estic fur market. However comparing with the interest of manufactures and consumers there are few of related references and books. So the purpose of this study is to put in order and summurize the manufacture in fur cloth-ing the informations of domestic and oversea fur markets and the other professional references. After all it is to help succeed in domestic and international fur markets and give the new ideas of designing and merchandising to the fur fashion industry. The results were as follows: 1. Contact with fur specialty stores in the international fashion cities and tourist cities directly. 2. Establish oversea factories in the low labor countries. 3. Exploit and invest in Russia china and the East European countries for suppliment of law materials and fur market. 4. Need the market research and promotion for encroachment in Japanese fur market. 5. Create the original brands with inter-national fashion sense. 6. Develop the manufacture line for diverse models in small lots matching with the modern life styles. 7. Need the fashion show exhibition pro-motion with reasonable prices and creative new designing with various color trimming texturizing and combination with the other materials. 8 Subdivide and distinguish labels into different types for avoiding with too much com-petition and comvenience of consumers. 9. Make an effort to weaken the black mar-ket the 30% of the domestic fur market.

This paper is about the local volatility for the price of a European quanto call option. We derive the explicit formula of the local volatility with constant foreign and domestic interest rates by adapting the methods of Dupire and Derman & Kani. Furthermore, we obtain the Dupire equation for the local volatility with stochastic interest rates.

Ginkgo trees have long been planted in Korea as roadside trees and ornamental trees, but the wood was seldom used except some utilization f3r small artifacts. Soaring prices of imported wood and future uncertainty about long-term supply of foreign woods have stimulated research on value-added utilization of less-utilized domestic wood resources such as Ginkgo wood. The processing properties of Ginkgo wood were investigated to determine its utilization potential in this study, and the results of treatability, drying characteristics, gluability, paintability, bending properties, chemical discoloration characteristics were presented.

본 연구에서는 생산비용의 변화에 대해 비대칭적 조정을 허용하는 오차수정모형을 바탕으로 국내 석유제품시장에서 자기가격과 경쟁가격의 변동에 대한 정유사들의 가격조정 행태를 분석하고 나아가 국제유가 및 환율의 변동에 대한 정유사들의 반응을 계량적으로 추정해 이들 가격의 비대칭적 특성을 분석하였다. 이를 위해 자동차연료인 휘발유와 경유를 분석대상으로 선정하고, 이들 유종에 대한 정유사별 세전공급가격을 석유공사의 Opinet으로부터 수집하였으며, 수집한 자료는 2009년 4월 5주부터 2015년 1월 3주까지의 주별 자료로서 관측치는 총 300개에 이른다. 정유사 공급가격은 국제유가 및 환율의 변동에 대해 양적으로 비대칭적 조정이 이루어지고 있음을 추정결과는 유의적으로 잘 나타내고 있다. 누적조정금은 대부분의 경우 이들 변수가 하락할 때보다 상승할 경우에 더 크게 나타난다. 시장점유율이 높은 정유사일수록 누적조정금은 크게 나타나 이들 정유사가 국제유가 및 환율의 변동에 민감하게 반응해 가격조정에서도 선도적 역할을 하고 있을 가능성을 시사한다. 한편 자기가격 및 경쟁가격의 균형이탈에 대한 정유사의 반응은 암묵적 가격담합과 경쟁적 가격조정의 두 행태가 동시에 나타난다. 암묵적 가격담합은 경쟁가격의 움직임과 같은 방향으로 가격을 조정해 상대가격과 일정수준을 유지하려는 조정행태를 의미하며, 추정결과 정유사들 반응의 대부분은 여기에 해당되었다. 일부 정유사는 경쟁가격의 상향이탈시 자기가격을 하향조정해 시장수요를 확보하려는 경쟁적 가격조정행태를 취하고 있음을 보인다.

More people have become interested in hybrid vehicles - which have been heralded as environmentally friendly automobiles - recently as the opening of domestic hybrid vehicle market draws near. Since gasoline, diesel and LPG hybrid vehicles will be produced, a need exists to conduct economic feasibility study of each vehicle type. This research analyzed projected benefits of these hybrid vehicles based on the 1600cc model. There are two categories of benefits: 1) reduced fuel costs for the owners of the vehicles; and 2) reduced environmental pollution cost. We conducted a sensitivity analysis and estimated the domestic consumer fuel costs based on the international oil prices of 100USD, 150USD, and 200USD per barrel. The analysis showed savings of 2 to 4 million Won in fuel cost and 1 to 2 million Won in environmental pollution cost; therefore, the hybrid vehicles are not economically feasible if they are between 3 to 5 million Won more expensive than the conventional internal combustion engine vehicles.

This paper discusses the design of monetary policy in a New Keynesian small open economy framework by introducing nominal wage rigidities and incomplete exchange rate pass-through on import prices. Three main findings are summarized. First, with the existence of an incomplete exchange rate pass-through and nominal wage rigidities, the optimal policy is to seek to minimize the output gap, the variance of domestic price and wage inflation, as well as deviations from the law of one price. Second, the CPI inflation targeting Taylor rule is welfare enhancing when there is a technological shock to the economy. The exception occurs when there is a foreign income shock, which minimizes welfare losses under the domestic inflation targeting Taylor rule. Last, two stylized Taylor rules turn out to be a bad approximation, but the modified Taylor rules that respond to the unemployment gap rather than the output gap are a closer approximation to the optimal policy.

The aim of this paper is to analyse the impacts on domestic production, value added, employment and import substitution of national technological information activities, using the 1995 Input-Output Tables in Korea. The total output of technological information amounted to 4,167 billion won at current prices. The total domestic output of 2,318 billion won was generated directly and indirectly and the amount of value added totaled 3,773 billion won. 119 thousand new jobs were created and total import substitution amounted to 1,346 billion won. As an increase of 4,167 billion won in technological information sector led to an increase of 7,437 billion won in total socio-economic repercussion effects, the multiplier was 1.8 in 1995.

Higher agricultural commodity prices are a particular concern for food importing countries like Korea that has a very low self-sufficiency ratio. Korean people eat approximately 4.5 million metric tons of rice each year, which is met without a problem by domestic production. The domestic production of corn and soybean which are important raw materials for commercial food processing and livestock feed is only minimal. Demands of corn and soybean in Korea are approximately 7.2 million and 1.3 million metric tons per year, respectively. Since Korean consumers are reluctant to accept biotech (GM) foods, Korean food processors are fighting an up-hill battle in purchasing non-biotech (non- GM) crops which are becoming scarce.
