This study investigated the effects of imported fisheries products on WTO/DDA tariff negotiations. To calculate the results, the study estimated the demand functions of imported fisheries products by using unit root and cointegration approaches. These approaches allowed us to solve spurious regression problems with macro-economic variables. In addition, this study surmised the effects of change by individually imported fish products from a tariff negotiation model using price elasticities of estimated import demand function. In a process of the analysis for estimating import effects, this study found out that 39 out of 128 imported fish products had positive (+) price elasticities or did not exhibit cointegrations. To cure this problem, this study suggested that the effects of these 39 imported products be estimated with the average variation rate of import volume, rather than by the Ordinary Least Squares approach. In this study, a case-study of tariff formula with coefficient 8 based on a 'Swiss formula' for priority duty rate of 2001 and 2008 was used by to analyze the effect of change in the 128 imported fish products of both years, respectively.

Purpose: This study examines components that dictate service quality of Online Travel Agencies. Research design, data and methodology: This study performed a survey that targeted people who have purchased travel products using Online Travel Agencies in the past year at Incheon International Airport. Out of 280 questionnaires, this study selected 249(88.9%) questionnaires for analysis. In analysis, this study used statistical package called 'SPSS 22'. Results: Based on the results, this study identified that company reputation and transactional stability influenced consumers' intent to share anecdotal and practical information. Conclusions: This study discovered several major findings. First, 'convenience' and 'price', two major factors in service quality, imposed positive effects on word-of-mouth intention of consumers. In particular, 'convenience' had the most significant impact. Next, this study verified the moderating effects of 'transaction safety' and 'reputation' on the effect relationships between 'convenience' and 'price', and consumer word-of-mouth intention. The results conclude that, in fact, some statistically significant differences among the effect degrees of the two independent variables on the dependent variable according to the safety level of transaction on Online Travel Agencies website do exist. In short, 'transaction safety' variable does have moderating effects on the above relationships.

This paper considers a Bayesian Network analysis for understanding the heterogeneous cross-category effects of different promotion activities and developing an efficient overall promotion strategy for a large retail store. More specifically we differentiate price reduction promotion and floor promotion and study their heterogeneous effect on consumer purchase behavior under a market basket setting. We then utilize Bayesian networks in identifying complex association structure in market basket dataset by analyzing the effects of different promotional activities and also include the effects of time, family income and size. We find from our Bayesian network analysis that the dominant cross-category promotion effect of price promotion is the indirect effect whereas the dominant cross-category promotion effect of floor promotion is the direct effect. Also, among the demographic variables we find that family size of the household is linked with more product categories compared to income and see that there are differences in the extent of the effects by product category. Finally, we also show the existence of products acting as a network hub and how they can be utilized by retailers faced with a limited marketing budget and suggest a more efficient promotion strategy.

This paper empirically examined the relationship between the housing market and the stock market to investigate the price and the asymmetric volatility spillover effects. The monthly housing price index and the monthly KOSPI were used for analysis. This research employed the EGARCH model. The analysis period was from January 1986 until June 2021 with periodization centered on the Asian Financial Crisis: before and after the crisis - the end of December 1997. The EGARCH model allows analysis of 'good news' and 'bad news' in understanding volatility. The price spillover effect was observed one way from the stock market to the housing market. On the contrary, the spillover effect was not found from the housing market to the stock market. The empirical evidence suggests that there are price and asymmetric volatility effects in the entire period of analysis in both housing and the stock markets. In the housing market, the negative effects of information were found pre-financial crisis while the positive effects, in other periods. However, in the stock market, the negative effects of information were found in the pre- and post-financial crisis periods. This means that the housing market is more affected by 'good news' than 'bad news' when information spreads to the markets while the stock market is more affected by 'bad news' than 'good news'. It is of significance to discover the variable returns by different information.

This paper investigates the asymmetric effects of crude oil price uncertainty on industrial stock returns under different market conditions (bearish and bullish stock markets). We consider a quantile regression method using monthly oil volatility index, KOSPI and 22 industrial stock indices from May 2007 to February 2019. Especially, we take care of the positive and negative changes of the oil volatility index to analyze asymmetric effects of the oil price uncertainty for the bearish and bullish stock market conditions. During the bearish markets, the oil volatility index has relatively strong statistically significant negative effects on the industrial stock returns. These effects gradually decrease when the market conditions became more bullish markets. In particular, positive changes in the oil volatility index yields a further significant decrease in 12 industrial stock returns during the extreme bearish markets. Moreover, during the bullish markets, negative changes in the oil volatility index have statistically significant negative effects on the 12 industrial stock returns. From the empirical results, we see that participants of the Korean stock market are sensitive to bad news in a recession.

To adapt to the constant change in the foodservice industry, dietary life is not only evolving variously and complicatedly, but eating-out styles are also changing fast. In this reality, this study is intended to examine the effects of marketing mix strategies on perceived value and loyalty in Korean restaurants. To achieve this, a survey was carried out to total 300 customers of Korean restaurants in Seoul from June 11 to June 30, 2013. The results were as follows. First, service experience, price and store image in Korean restaurants had a positive effect on the perceived value. Second, price, advertisement and store image in Korean restaurants had a positive effect on the loyalty. Third, the perceived value had a significant positive effect on the loyalty. As stated above, service experience, price and store image, and price, advertisement and store image in Korean restaurants had an effect on the perceived value and the loyalty, respectively. Also, the perceived value had an effect on the loyalty. Consequently, these factors are very useful as marketing mix strategies in Korean restaurants.

This paper estimates the effects of Air Cargo companies' fuel surcharge collusion on the final airfreight prices. We show that the final prices have not been generally higher than the 'but-for prices,' and even been significantly lower for some companies. We analyze the possible reasons for such findings, and conclude that the collusion on fuel surcharges has not been successful due to the oil price hike in the cartel period. We also find that the oil price elasticities of fuel surcharges are significantly lower than 1.

This paper investigates the manner in which house prices affect macroeconomic variables through a house price channel by applying the method of Iacoviello (2005) to Korean data, and establishing a DSGE model with complementarity. This paper found that higher LTV ratio coupled with stronger complementarity results in the co-movement in both consumption and housing. For instance, the results show that when the LTV ratio and complementarity stands respectively at 50% and 0.42, an 1% rise in house prices increases consumption by 0.057%, and when the complementarity parameter increases to 0.52 with LTV remains unchanged at 50%, consumption rises by 0.047% per 1% increase in house prices. An increase in house prices leads credit constraints for borrowers to become more loose as value of a house rises as a collateral. The increase in household credit enables more consumer spending, eventually leading to increased consumption. A key link in which house prices are connected to macroeconomic variables is change in consumption. To put it simply, a rise in house prices leads to an increase in consumption, which consequently impacts the overall macro-economy. At this point, complementarity is found, in that the elasticity of intra-temporal substitution between housing and consumption is estimated at 0.42, which plays an important role in the house price channel by amplifying the effects of house prices on consumption.

This study analyzed how alternative investment goods would affect a market in a neighboring shopping area in order to provide parties involved in the investment market of this neighboring shopping area with standards which would help them when they try to make a reasonable determination. The study estimated forms and explanation power of the effects of a bid rate of a neighboring shopping area, and came up with those results as follows. Increases in the representative macro economic indicators, the composite stock price index and the fluctuation rate of land price, including the real estate business would have a positive influence on the market of the neighboring shopping area as playing a circumstantial evidence of market recovery and yet, the increase in interest rate, the alternative investment goods, would reduce the relative price-earnings ratio which would, eventually, negatively affect the charm of the investment in the market of the neighboring shopping area. The study, now, understands that housing with a feature of consumers' goods and neighboring shopping area with a feature of investment goods would not have great concern with each other as they are observed to be two different markets from an aspect of interactionism.

This study analyzed the effects of price perception and product attributes on brand loyalty and repurchase intention, and compared the differences in high- and low-priced cosmetic brands. Data were collected from female consumers in their 20s to 40s and a total of 411 responses were used for the final analysis. Findings were as follows. First, when comparing high- and low-priced brands, personal attribute and experiential attribute among cosmetic attributes, brand loyalty, and repurchase intention of high-priced showed the higher mean scores than those of low-priced. Second, all of three cosmetic attributes and P-Q/prestige were significant for high-priced brand loyalty, while experiential attribute, personal attribute, P-Q/prestige, and price consciousness were significant for low priced brand loyalty. Third, with respect to repurchase intention, all of three cosmetic attributes, P-Q/prestige, and sales proneness were significant for high-priced, while experiential attribute, personal attribute, and P-Q/prestige were significant for low-priced. Personal attribute contributed the most to high-priced brand loyalty and repurchase intention, whereas experiential attribute to low-priced. The findings of this study would be helpful to understand the purchase of high and low priced cosmetic brands. The managerial implications for cosmetic brand marketers were provided.
