The result of variance decomposition through yield of Treasury of 30 year maturity of USA, S&P 500 index, stock price of KEPCO has 76.12% of impulse of KEPCO stock price at short-term horizon, but they have 51.40% at long-term horizon. After one year, they occupy 13.65%, and 33.25%. So their effects are increased. By the way, S&P 500 index and yield of Treasury of 30 year maturity of USA have relatively more effect for forecast of stock price oi KEPCO at short-term & long-term. The yield of Treasury of 30 year maturity of USA more than S&P 500 index have more effect for stock price of KEPCO. It is why. That foreign investors through fall of stock price of USA invest for emerging market is less than movement for emerging market of hedge funds through effect of fall of yield of Treasury of 30 year maturity of USA, according to relative effects for stock price of Korea companies. The result of variance decomposition through won/dollar foreign exchange rate, yield of corporate bond of 3 year maturity, Korea Stock Price index(KOSPI), stock price of KEPCO has 81.33% of impulse of KEPCO stock price at short-term horizon, but they have 41.73% at long-term horizon. After one year, they occupy 23.57% and 34.70%. So their effects are increased. By the way, KOSPI and won/dollar foreign exchange rate have relatively more effect for forecast of stock price of KEPCO at short-term & long-term. The won/dollar foreign exchange rate more than KOSPI have more effect for stock price of KEPCO. It is why. The recovery of economic condition through improvement of company revenue causes of rising of KOSPI. But, if persistence of low interest rate continues, fall of won/dollar foreign exchange rate will be more aggravated. And it will give positive effect for stock price of KEPCO. This gives more positive effect at two main reason. Firstly, through fall of won/dollar foreign exchange rate and rising of credit rating of Korea will be followed. Therefore, foreign investors will invest more funds to Korea. Secondly, inflow of foreign investment funds through profit of won/dollar foreign exchange rate and stock investment will be occurred. If appreciation of won against dollar is forecasted, foreign investors will buy won. Through this won, investors will do investment. Won/dollar foreign exchange rate is affected through external factors of yen/dollar foreign exchange rate, etc. Therefore, the exclusion of instable factors for foreign investors through rising of credit rating of Korea is necessary things.

The main purpose of this study is to analyze the effects of stock price and real estate price on the money demand. We investigated the demand for money for 25 money units of 10 countries. To estimate the money demand functions, Johansen's cointegration and ARDL-bounds test were employed. Additionally, Stock and Watson's DOLS method was applied to estimate long-run cointegration vectors. According to the results of cointegration test, stock price and real estate price are crucial in the long-run equilibrium relationship. There were no cointegration relationships among money demand, real income, interest rate, and exchange rate in 12 money unit models. However, by including stock price and real estate price on the tested models, we could find strong cointegration relationships, using ARDL-bounds test. The results of DOLS confirm that stock price and real estate price are effective factors influencing on money demands. Especially, the coefficient of real estate price is statistically significant in the 19 out of 20 money unit models. However, the direction and magnitude of coefficients of asset prices are different across countries and money units.

This study examined: 1) the effects of fashion luxury product price discounts in social commerce on perceived benefit and purchase intention, and 2) differences in such effects by social commerce trust, brand and design preferences for luxury products as well as social commerce and online luxury product purchase experiences. Three discount rates representing high, mid, and low for a luxury product sold in social commerce were manipulated and tested on female consumers and 486 online responses were analyzed. The results revealed that the price discount affected perceived benefit but did not affect purchase intention. Benefits were highly perceived at high and mid discount rates compared to the low rate. Social commerce trust, brand preference, and design preference affected perceived benefit and purchase intention, but the interaction effect with price discount was observed only in the design preference to perceived benefit. The purchase experience of online luxury products also affected purchase intention. Implications from the results were also discussed.

Evaluation on jean products were varied although they were the identical jeans. Therefore, we could confirm the bias by price. brand, and store when consumer evaluating jean products. The various consumer characteristics also provided effects evaluation on jean products. An evaluation on jean products is very subjective and the degrees depending on these three cues could be varied by consumer's characteristics. For empirical study, experiments by the subjects among students of ewha womans university were done by using jeans as stimulus. Data was collected by a questionnaire made up by a researcher based on the theoretical and pretest. Data was analyzed by ANOVA, factor analysis, grouping analysis, F-test, and etc. 571 data were analysed out of the 600 data. Cues such as price, brand, and store affected significantly the evaluation of jeans. The most important cue of all three was store, then price, and then brand. These three cues affected the evaluation of jean products separately and together. The result of the study was that the consumers characteristics mediated the effects of extrinsic cues like price, brand, and store on jean products evaluation. Consumer's characteristics like prior knowledge and shopping orientation mediated the effects of price, and store cue on jean products evaluation.

In this paper, we investigate the differences between LNG price of South Korea and Japan. Although S. Korean and Japanese LNG markets have similar structures, there are some differences in the price formation. From DCC-MGARCH, we confirm that Japan LNG price have less persistence of disturbance on time than S. Korean LNG price. The conditional correlation also shows linkage effects between LNG prices and impacts of S-curve and DS-curve. Moreover, ARDL estimation result shows that there is co-integration in all models and that impacts of Fukushima accident and LNG volumes are responsible for the increase in Japanese LNG price. Also, adjustment speed of error correction term shows that Japan's deviation from long-run equilibrium disappears faster than S. Korea does, indicating relatively strong Japanese linkage between LNG price and oil price.

This article analyzes the effects of energy price increase induced by GHGs mitigation policy on automobile industry empirically. An increase in energy price due to GHGs mitigation policy does not have a significant effect on the production and the value-added in automobile industry. Electricity price has a negative effect on the production and the value-added in automobile industry, but it is not significant. However, employment is significantly affected by a change in electricity price. Export is also affected negatively, but the effect is insignificant. These results imply that GHGs mitigation policy such as carbon tax might affect adversely the employment in automobile industry. Especially, their effects on employment are significant. Therefore, some moderating measures to relieve the adverse effects on employment in automobile industry should be called upon with the implementation of GHGs mitigation policy.

This study was designed to find out the effects of country-of-origin and price on the perceived quality, perceived value and purchase willingness of t-shirt products. This study will allow marketers to find the target consumers and to choose both the suitable country -of -origin and the reasonable selling price. This study was based on theoretical and empirical methods. For the empirical methodology, 3${\times}$3 between subjects factorial design with country-of-origin (U.S.A. vs. Korea vs. China) and price(high price vs. middle price vs. low price) was used. The nine types surveys by country-of-origin and price were transmitted to 960 undergraduate and graduate school students in Seoul. A total of 912 questionnaires were used in the final statistical analyses using factor analysis, MANOVA, Duncan test, and Tukey test. The results of this study were as follows: First, in the case of the perceived quality, participants evaluated t-shirt products better when the origin is U.S.A. followed by Korea and China in the order. Second, price affected the perceived value and purchase willingness. In the perceived value and purchase willingness, low priced t-shirt products were evaluated higher than the middle and high priced ones. Third, in the perceived quality, high priced Korean t-shirt products were evaluated lower than high and middle priced American t-shin products. In the perceived value, low priced Chinese t-shirt products were evaluated lower than middle priced Korean t-shirt products. In the purchase willingness, low priced American and low priced Korean t-shirt products and middle priced Korean t-shirt products were evaluated higher than all priced Chinese t-shirt products.
