For some consumer goods, consumers expect additional benefits or returns after purchasing or using them. This kind of consumer goods that consumers expect some additional benefits or returns after consumption (hereafter consumer goods of investment or CGOI) need not only an approach of simple purchasing perspective but also an approach from investment perspective. Current study tries to figure out if consumers react differently in their purchasing intentions toward CGOI between when they focus on the product's quality, functions, or other current state related information (i.e., simple purchase focus) and when they focus on the benefits that will be generated after using the product (i.e., investment focus). According to the results, while consumers' purchasing intentions toward CGOI in the investment mode are greater when the price is low than when the price is high, consumers' purchasing intentions toward CGOI in the simple purchasing mode are greater when the price is hgih than when the price is low.

In this study, multi-sectoral partial equilibrium and computable general equilibrium models of Taiwan are used to investigate the direct and indirect effects of energy price increases on overall economies and agro-food sector in Taiwan. The results suggest that agricultural prices, production cost would increase between 0.27% to 1.88%, and a reduction in GDP around 0.39% to 0.54 %. The negative impact on livestock sector is slightly higher than that on the crop sector. Negative impacts are also observed in the employment and wages. The rising oil price has the potential to discourage production of energy-intensive activity because of the possibility of substitution and adaptations. The growth rate of real GDP will shrink by 0.64% to 1.06% and CPI will increase by 1.17% to 1,95%. Both the agriculture and non-agricultural sector also respond by raising output prices by 0.80% to 1.33%. The rising international oil price has urged the government to take policy actions like using alternative fuels such as biodiesel, bioethanol, and adopting measures to cut down on energy consumptions mainly in transportation sectors in response to public concern over economic shocks.

In order to set public policy to overcome 'water crises' on both quantity and quality of water, we looked into the national-economic role of Korea water utility by two approaches. First, we examined the relationship between water consumption and economic growth during 1978-94, a period of rapid increase in water consumption caused by prompt industrialization and urbanization. The price and income elasticities of aggregate and sectoral demand for water were estimated. Second, we developed a static input-output(I-O) framework for analysing water issues in the short run. In addition, we discussed two topics in its application: i) sectoral failure(shortage) costs by supply-driven I-O model, ii) Leontief price model's sectoral pervasive effects of price due to rise in water rate. In conclusion, we found that investments to water sector and water shortage has a big influence on the standard of living and industrial production. Also we found that raising water rate to encourage conservation or to create investment funds decreases demand for water significantly but has a small influence on overall price levels.

This paper analyzes Onbid car auction data by employing various methods, including structural estimation, to identify main factors which decides auction prices and figure out what effects those factors are making on the auction price. I then discuss on how to maximize sellers' revenue in OnBid car auctions. The government and public institutes sell their assets through the OnBid auction, hence the optimal design of the OnBid auction is important. The paper's main findings are as follows: (ⅰ) The independent private value model explains OnBid car auction data better than the correlated private value model or the interdependent value model; (ⅱ) Both the number of bidders and the ratios of the auction price to the evaluation value were lower in the auctions posted by the Kamco than auctions by institutes other than the Kamco; (ⅲ) Some auctions require that at least two bidders should submit a bid no less than the reserve price for sale. In those auctions, both the number of bidders and each bidder's valuation on the auctioned object were lower than in auctions without that requirement; (ⅳ) The sum of sellers' revenue would be decreased in the simulation with the reserve price higher by 5%, 10%, and 20% across auctions by institutes other than Kamco.

In recent years retail competition has intensified, generally as a consequence of technologies, more sophisticated management practices and industry consolidation. An understanding of current customers' loyalty intentions and their determinants is an important basis for the identification of optimal retailer actions. The focus of this study is to examine the links between patronage intention and the effects of various antecedents of current customers' store loyalty intentions in fashion store. 340 female universities students living in Seoul were analyzed by utilizing multiple regressions to investigate the predictability of each of the 4 different sets of variables(consumer value, source of information, clothing benefits, importance of store attributes) on four patronage intentions of apparel shopping(discount store, speciality store, conventional market, Fashion shopping mall). Four factors were significant in predicting conventional market patronage intention. Brand had a negative coefficient, while price, social affiliation, store fashion service/promotion had positive coefficients. Fashion shopping mall were predicted by five factors:brand had a negative coefficient, while media, social affiliation, price, uniqueness had positive coefficients. For specialty store, four factors were significant: brand had a negative coefficient, while store fashion service/promotion, personal sources, uniqueness had positive coefficients. Four factors were significant in predicting discount store patronage intention :price, store fashion service/promotion, social affiliation, variety of price & product had positive coefficients. Despite the relatively low $r^2s$, all four variables appeared to have, to some degree, predictability of choosing among four different types of store for apparel shopping. Based on the results, patronage intention profiles for four retail stores were developed. Marketing implications are discussed.

The objective of this study consists of facilitating seafood consumption by increasing its intake opportunities for consumer through analysis of sliced raw fish. A study on sliced raw fish consumption was conducted on 630 citizens of Busan(252 men and 378 women), attending high school and university, and employedas housekeepers and salaried employees. The goal of the study was to assess the attitude and degree of satisfaction obtained from eating sliced raw fish and ultimately to promote greater seafood consumption. A self-administered questionnaire was used to record the results. The results were as follows : About sixty percent of the respondents appeared to like or not to be reluctant to eating sliced raw fish. The main reasons for favoring sliced raw fish were its taste and nutritious effects. All ages liked sliced raw fish, but teenaged women, on average, tend to dislike sliced raw fish. The most preferred sliced raw fish was flounder. Most of the panelists preferred korean rock fish, and red sea bream due to their ordinary muscle. Sliced raw fish of the 2nd and 3rd variety were the most popular. For most of the sliced raw fish, the own-price elasticity came out to be relatively low. This can be explained by the fact that sliced raw fish is characteristically purchased based more on quality and freshness, than on price. SINGSINGWHE(SSW)-fresh sliced raw fish should be stored at 0$^{\circ}C$ for no longer than 10hrs. Taste, nutritional value and low price have the potential to promote the consumption of seafood. Factors which can reduce the consumption of sliced raw fish were safety due to Vibrio septicemia, rainy day, indistinct origin, and high rices. To promote sliced raw fish consumption, the subjects recommended the quality improvement and low price.

The young generation in life cycle that social position is rapidly changing is play an important role in a regional development because they can increase social and natural population in the region. This study analyzed the relationship between the movement of young generation and the regional characteristics including housing market characteristics in Seoul. As the results, the movement of young generation was influenced by commuting distance and location of jobs as the gravity model has suggested. In addition, housing supply and housing price (or Jeonse price) is an important factor for the movement of young generation. It can be inferred that the more price gap such as Jeonse price and housing supply gap are increased, the more out-migration of young generation in Seoul is increased. However, the housing demand of young generation in employment centers will be increased because jobs contribute to increasing the inflow of young people. Therefore, the policies of central and Seoul government that supply housing in job rich and high accessibility areas are needed for young generation. In addition, if public housing and affordable housing are supplied in the other areas, it can contribute to reduce the out-migration of young people in Seoul.

Oil and steel prices, which are major pricescosts in the shipbuilding industry, were predicted. Firstly, the error of the moving average line (N=3-5) was examined, and in all three error analyses, the moving average line (N=3) was small. Secondly, in the linear prediction of data through existing theory, oil prices rise slightly, and steel prices rise sharply, but in reality, linear prediction using existing data was not satisfactory. Thirdly, we identified the limitations of linear prediction methods and confirmed that oil and steel price prediction was somewhat similar to actual moving average line prediction methods. Due to the high volatility of major price flows, large errors were inevitable in the forecast section. Through the time series analysis method at the end of this paper, we were able to achieve not bad results in all analysis items relative to artificial intelligence (Prophet). Predictive data through predictive analysis using eight predictive models are expected to serve as a good research foundation for developing unique tools or establishing evaluation systems in the future. This study compares the basic settings of artificial intelligence programs with the results of core price prediction in the shipbuilding industry through time series prediction theory, and further studies the various hyper-parameters and event effects of Prophet in the future, leaving room for improvement of predictability.

In this study, variables were constructed based on previous studies to examine the effects of overseas direct purchase quality factors(information quality, system quality, and service quality), perceived value, and purchase intention. In addition, differences between groups were examined through the moderating effect of price sensitivity. A survey was conducted on overseas direct purchase users, and 178 questionnaires were used for empirical analysis. The collected data was analyzed by SPSS 25.0 and AMOS 21.0. The results are as follows: First, it was found that the quality factors of overseas direct purchase had a positive effect on perceived value. Second, it was found that the quality factors of overseas direct purchase had a positive effect on purchase intention. Third, as a result of testing the moderating effect of price sensitivity in the relationship between the quality factors of overseas direct purchase, perceived value, and purchase intention, there was no difference between groups. In conclusion, the implications and limitations of this study are presented.

In this study, we investigate the relative effectiveness of the two types of brand extensions (sequential extensions vs. direct extensions) in dissimilar extensions and examine the moderating role of two key variables - brand concept(functional brand vs. symbolic brand) and price of target extension product(low vs. high). The results from two experiments show that consumers evaluate the target extension product more favorably when brand is extended sequentially to dissimilar categories than when it is extended directly. However, the difference of target extension product evaluation between sequential extensions and direct extensions decrease when brand is symbolic and price of target extension product is high. Theoretical and managerial implications of the finding are discussed and inplications for future research are suggested.
