At present Cournot model is one of the most commonly used theories to analyze the gaming situation in oligopoly market. But there exist several problems to apply this model to electricity market. The representative one is to obtain the inverse demand curve able to be induced from the relationship between market price and demand response. In Cournot model, each player offers their generation quantity to accomplish maximum profit, which is accomplished by reducing their quantity compared with available total capacity. As stated above, to obtain the probable Cournot equilibrium to reflect real market situation, we have to induce the correct demand function first of all. Usually the correlation between price and demand appears on the long-term basis through the statistical data analysis (for example, regression analysis) or by investigating consumer utility functions of several consumer groups classified as residential, industrial, and commercial. However, the elasticity has a tendency to change continuously according to the total market demand size or the level of market price. Therefore it should be updated as trading period passes by. In this paper we propose a method for inducing and updating this price elasticity of demand function for more realistic market equilibrium.

At present, the Cournot model is one of the most commonly used theories to analyze the gaming situation in an oligopoly type market. However, several problems exist in the successful application of this model to the electricity market. The representative one is obtaining the inverse demand curve able to be induced from the relationship between market price and demand response. In the Cournot model, each player offers their generation quantity to obtain maximum profit, which is accomplished by reducing their quantity compared with available total capacity. As stated above, to obtain the probable Cournot equilibrium to reflect the real market situation, we have to induce the correct demand function first of all. Usually the correlation between price and demand appears over the long-term through statistical data analysis (for example, regression analysis) or by investigating consumer utility functions of several consumer groups classified as residential, industrial, and commercial. However, the elasticity has a tendency to change continuously according to the total market demand size or the level of market price. Therefore it should be updated as the trading period passes by. In this paper we propose a method for inducing and updating this price elasticity of demand function for more realistic market equilibrium.

This study aims to examine if a consumer's evaluations of and purchase intentions towards textiles and apparel-related cultural products are influenced by their culture, as indicated by their nationalities. Additionally, several psychological variables, such as novelty-seeking tendency, world-mindedness, and familiarity with Northeast Asian culture were included in the analyses to compare the relative importance of cultural influences with the importance of individual characteristics. To conduct a quantitative analysis, we collected data from 400 female consumers in two countries: 200 from the USA and 200 from China. Key findings showed that, nationality and novelty-seeking were found to have a strong influence on purchase intention when product evaluation variables were not included. Evaluation of appearance and Northeast Asian design emerged highly significant predictors of purchase intention for Korean cultural products, regardless of the product type. Cross cultural comparative research on cultural product evaluations is extremely rare. This study focused on groups of consumers residing in the US and China and asked them to evaluate a series of textiles and apparel-related cultural products produced in Korea.

This article is to understand the implications and ideological meaning of female normative beauty reproduced by the idealizing phenomena of the hyper-real body as a process of the normalization of the body projected in fashion magazines with a focus on the body created by the increased influence of mass media in consumer capitalism. This study conducts a literature research and semiotic analysis as the method of investigation and focuses on the body images of the beauty articles in Vogue Korea. The idealizing phenomena of the hyper-real body in fashion magazines emphasizes that the body is an exchangeable substance that can be disassembled to adjust to accord with the standards and norms of society, that the ability of individuals to manage their body is enhanced by a rise in social class, and concludes that the superficial alteration of the body image is related to the standard of a moral tendency where a young and slender figure is considered to be a well managed body image.

Purpose - The ultimate purpose of this research is to analyze the influence of personal disposition on shopping value and behavioral intention by expanding the theory of planned behavior (TPB). Research design, data, and methodology - An attempt was made to examine the effects of personal disposition (reflecting duty-free shop characteristics) on three selective actions of consumers - compulsive buying, variety seeking, and price sensitivity. We conducted a questionnaire survey with the users of airport duty-free shops, downtown duty-free shops (offline), and online duty-free shops. In total, 410 copies of the questionnaire were analyzed using a structural equation model. Results - According to the results, compulsive buying, variety seeking, and price sensitivity significantly affected shopping value. Shopping value and subjective norms both had significant effects on attitude, the major variable in the TPB, and attitude had the greatest effect on behavioral intention, followed by subjective norms and perceived behavioral control in descending order. Conclusions - This study has academic implications in that it extends the existing theories of planned behavior and applies it to consumer characteristics and shopping value. It has practical implications as well in that it provides basic data that can be used to establish concrete marketing strategies for duty-free shop owners targeting segmented markets by closely examining customer desires.

Recently, the call for better accountability and social responsibility from corporations has been regularly voiced, both in the academic literature and in public discussions. This poses a challenge to the existing literature in understanding consumption behaviors to direct them toward sustainable development. This study investigates the purchase intention of Gen Z consumers in Vietnam with green packaging products. Data were collected from 914 respondents by online questionnaire and then analyzed using OLS. The results suggest the significant influence of customers' income and packaging in driving customers' intention to use environmentally-friendly products. Specifically, consumers in a higher income class participate more actively in green purchases. However, problems associated with inadequate packaging are also illustrated, resulting in the poor perception of green messages and poor practice of ecological actions. Besides, subjective norms and green trust are found to be adversely related to green consumer intention. In addition, gender disparity in green behavior is reported, where female consumers show a higher tendency to ecological consumption than their male counterparts. Other demographic factors are also included in the model as control variables, which are age, education, price, environmental literacy, environmental concern, and psychological awareness, but they do not have a significant impact on green purchase intention.

Purpose: This study aims to explore the factors affecting the willingness to pay for chicken delivery services targeting college students. The results of this study provide insights for improving food delivery market services and developing effective marketing strategies. Research design, data and methodology: A survey employing a questionnaire was administered to students at Chungbuk National University over a 10-day period from May 15 to May 24, 2023. Out of 232 distributed surveys, 218 were considered suitable for analysis. Binomial logistic regression analysis was conducted with the willingness to pay for delivery fees contingent on chicken price, serving as the dependent variable. Results: The main findings are following. First, as the price of chicken increases, the percentage of individuals willing to pay more than 2,000 won for delivery services decreases. Second, regardless of chicken price, males exhibit a lower tendency to bear higher delivery service fees compared to females. Lastly, those who lack awareness of their recent delivery fees or have previously paid charges exceeding 3,000 won demonstrate a greater propensity to pay higher delivery service fees compared to those who have paid fees below 3,000 won. Conclusions: It is essential for chicken sellers to identify key customer segments such as single-person households, and offer pricing and services tailored to their needs and preferences.

The purpose of this paper is to investigate how the young fashion which maintains a large share of fashion market emerged in the 1960s, its characteristics and what its influences on the contemporary fashion industry are. In particular, I am going to consider the significance of the young fashion by looking at the formation of niche market, the emergence of mass market for fashion, the expansion of aesthetic categories. we will be able to see the 60s young fashion of the young generation who emerged as new consumers in mass consumer culture exerted important influences on the contemporary fashion industry. First, the counterculture of young generation who rebeled against the uniformity of mass production helped the formation of new niche market. Second, the young fashion which pursued the lower prices for fashion made a big contribution to the popularization of fashion. The young generations tendency to demand new things and rapid change coincided with that of inexpensive popular fashion people can buy and change more easily than expensive high fashion. Lastly, the playful tendency of the young fashion expanded the aesthetic boundaries of the clothing, going beyond the uniformity of modernism with the emergency of diverse fashion materials - fabric and textiles - enable by technological development and the miniaturization of forms as revealed in mini skirt.

This study was established to understand how Arte Povera has affected the contemporary fashion based on the analyses of its characteristics and may provide a prospective view to predict style of future fashions. The results were as follows : 1) “The poverty” shows such characteristics as patch work, intentional mismatch, and tendency to prefer slightly used style. This meaning can be explained as direct expression from a sense of alienation, against to consumer economy, and dual-expression between poverty and wealth. 2) “Anti-formativeness” can be described for misinterpretations of creation, arrangement, and informal silhouette due to distortion of the human body. This expression includes such meanings as against to traditionalism, ignorance of rationality, and disorganization of the concepts between the beauty and the ugly. 3) “Naturalism” indicates as characteristics of use of natural materials and primitive expression. This expression could be generated from adaptation to the nature and desire toward uncivilized society due to skepticism about modern society. 4) “Symbolism” shows such expressions as an isolated feeling from society, and metaphoric sense from specific situations because there are too many applications of imported materials. This tendency can be also explained with the creations of spaces for opened concepts through disorganizations of territory, obscurity, and irregularity.
