The study was conducted to examine consumers' awareness and perceptions on forest certification and their willingness to buy and pay price premium for certified wood products especially for selected four wood products. A total of 136 residents in Seoul and Gyeonggi Province were interviewed in the autumn of 2008. Although only 24.3 percent of the consumers are aware of forest certification, 82.4 percent of the respondents recognized the need and significance of forest certification. In general, 77.2 percent of the respondents were willing to buy certified wood products. Majority of the respondents, 84 out of 136 respondents (61.8%) expressed their willingness to pay (WTP) from more than 0 percent to less than 10 percent. Consumers' average WTP for certified wood products was estimated to be 5.6 percent. From the results of the study, lower priced wood products, such as copier paper (WTP=9.8%) and wood frame (WTP=11.6%), have higher price premiums than high priced products, such as wood table (WTP=6.8%) and wood flooring (WTP=7.6%). In conclusion, there could be feasible markets for certified wood products in South Korea as four out of five consumer are willing to pay more for such products. For the forest certification system to be adopted and widely accepted, the perceptions of forest stakeholders including consumers should be further increased.

The purpose of this paper is to test whether prices of mobile communication service reflect their varying degrees of call quality, controlling for other service attributes. As, in fact, service is intangible goods difficult to measure its value, this paper makes use of econometric model, hedonic price analysis. Hedonic price analysis, has ever been applied in public or environmental economics, is employed and produces estimates of the prices (or the contributions toward the total price) for each characteristic. This paper applied hedonic technique to the value measurement of a service property for the use of Korean mobile communication. This paper uses actual transaction prices of mobile communication service to determine whether or not the market functions in pricing call quality of mobile communication service. Finally, this show that the willingness to pay of consumer increases as call quality increases and so market makes prices on call qualities. Thus, major concern in this paper is about value measurement o service quality, and also suggest of the possibility to determine call quality value (or price) of mobile communication service.

One of the main challenges receiving much attention in the Rwandan agriculture and food industry in recent decades is the increases in maize prices. Indeed, a rise in maize prices causes higher living expenses for households because maize, which is a major staple food crop, constitutes a significant share of total food consumption among households in Rwanda. The aim of this study was to assess the extent of integration and how prices are transmitted between retail and wholesale markets of domestic maize in Rwanda. This study used monthly data of retail and wholesale prices of maize from January 1995 to December 2019. This empirical investigation was based on a linear cointegration approach and an asymmetric error correction model framework. Using the augmented dickey-fuller residual-based test and the Johansen Maximum Likelihood cointegration test, the results revealed that the retail and wholesale markets of maize are integrated. Hence, prices in these markets do not drift apart in the long run. The results of the Granger causality test revealed that there is a unidirectional causal relationship flowing from wholesale prices to retail prices, i.e., wholesale prices influence retail prices. Accordingly, the results from the asymmetric error correction model confirmed the presence of a positive asymmetric price transmission between wholesale and retail prices of maize in Rwanda. Thus, we suggest that policymakers take a critical look at the causes and factors that may influence asymmetry price transmission.

Purpose: This study divides choice attributes that can help strengthen the competitiveness of traditional markets into product, price, personnel, and physical evidence. This study also examines which choice attributes affect customer value perception, satisfaction, and loyalty. Research design, data, and methodology: The data were collected from 542 traditional customers aged 20 or older who frequently visit traditional markets across the country and analyzed using the Smart PLS 4.0 program. The survey was conducted with the help of an online survey company for a total of 14 days from April 7, 2023 to April 20, 2023. Result: First, product, price, and employee quality have a positive impact on utilitarian and hedonic value, but physical evidence does not. Second, product, price, and employee quality have a positive impact on hedonic and hedonic value. Second, utilitarian value has a positive impact on satisfaction and revisit intention. Third, hedonic value has a positive impact on satisfaction, but does not on revisit intention. Lastly, satisfaction has a positive impact on revisit intention. Conclusions: Based on the S-O-R model and the theory of consumption value, this study proposed and examined an integrated framework in which satisfaction leads to revisit intention through selection attributes acting on perceived value.

This study analyzed consumers' preferences and price sensitivity to native chickens. A survey was conducted from Jan 6 to 17, 2014, and data were collected from consumers (n=500) living in Korea. Statistical analyses evaluated the consumption patterns of native chickens, preference marketing for native chicken breeds which will be newly developed, and price sensitivity measurement (PSM). Of the subjects who preferred broilers, 24.3% do not purchase native chickens because of the dryness and tough texture, while those who preferred native chickens liked their chewy texture (38.2%). Of the total subjects, 38.2% preferred fried native chickens (38.2%) for processed food, 38.4% preferred direct sales for native chicken distribution, 51.0% preferred native chickens to be slaughtered in specialty stores, and 32.4% wanted easy access to native chickens. Additionally, the price stress range (PSR) was 50 won and the point of marginal cheapness (PMC) and point of marginal expensiveness (PME) were 6,980 won and 12,300 won, respectively. Evaluation of the segmentation market revealed that consumers who prefer broiler to native chicken breeds were more sensitive to the chicken price. To accelerate the consumption of newly developed native chicken meat, it is necessary to develop a texture that each consumer needs, to increase the accessibility of native chickens, and to have diverse menus and recipes as well as reasonable pricing for native chickens.
