본 연구에서는 IMF 경제위기 이후 서울의 아파트 가격이 지역에 따라 양극화 되는 현상을 거주지 분리 심화라는 틀을 통해 분석하고자 한다. 이를 위해 서울의 지역별 아파트 가격 차별화와 고학력집단의 거주지 분리 정도를 밝히고, 아파트 가격과 고학력집단 거주 비율의 상관관계를 밝히고자 한다. 연구 결과 거주지 분리와 아파트 가격의 차별화라는 공간적 과정은 밀접한 관계를 맺고 있는 것으로 나타났다. 서울시 행정동을 단위로 45$\sim$59세 인구의 고학력집단 비율을 시계열적으로 분석한 결과 1990년에 이미 현재와 같은 학력집단별 거주지 분리가 관찰되고 있어, 거주지 분리가 지속적으로 재생산되고 있음을 알 수 있다. 행정동별 고학력집단 거주 비운은 아파트 가격의 행정동별 변이와 밀접한 관련을 보이고 있다. 1997$\sim$2003년 사이 아파트 가격의 상승은 고학력집단이 공간적으로 집중되어 있는 지역을 중심으로 발생하였다. 그외 지역의 아파트 가격은 정체되어 있거나 소폭의 상승을 보여 아파트 가격의 지역차가 매우 강화되었다. 아파트 가격의 지역별 차별화는 거주집단에 따라 지역이 달라지는 거주지 분리 과정을 적극적으로 반영하고 있다.

The current advance of IT and the e-commerce triggers the wide practice of dynamic pricing in all industries although the price discrimination has been very cautiously applied in the limited areas in the past. The price discrimination which offers different prices for each customer depending on their preference and buying behaviors has recently gained attention as it could provide superior benefits to sellers. The wide adoption of price discrimination, on the other hand, is reported to face buyer resistances and complaints. Our limited understanding on the perception of price fairness, which we think is key concept in the price discrimination on the Internet-enabled transactions, motives us to investigate factors that affect the perception of price fairness. This study focuses on illusion of control and lateral customer relationship to investigate their effects on price fairness in online auction and group purchase context. By conducting laboratory experiments, our study demonstrates that customers' perception on illusion of control in price determination and advantageous lateral customer relationship significantly affect price fairness perception in both online auction and group purchase environment. The findings are expected to provide researchers and managers with useful insights to develop better pricing strategies and design effective dynamic pricing mechanisms.

We devised a grape variety model to estimate the impact of lowering the Shine Muscat quality level on the grape market. Shine Muscat has become a popular grape variety in Korea. Accordingly, the area devoted to the harvesting of Shine Muscat has increased dramatically since 2016. Our study examines how a reduction in the quality of Shine Muscat affects other grapes such as Campbell Early, giant peak, and Muscat Bailey A (MBA). The Armington model was used to impose consumer preferences and product differentiation assumptions. We found that a decrease in the consumer preference for Shine Muscat realized by lowering the quality of Shine Muscat largely reduces the price of this variety. Also, the prices of other grape varieties fell via a substitute effect. Moreover, if grape varieties were more differentiated, the reduction in the price of Shine Muscat would be greater, while the decreases in the prices of other grape varieties would be smaller. These results imply that farmers of Shine Muscat must continue with quality management efforts to avoid the negative effect of changing consumer behavior with regard to Shine Muscat against a reduction in its quality. Our model introduces a product differentiation model for the fruit market and helps policymakers and farmers understand the impact of changing market conditions in the fruit market.

Online streaming wars are intensifying. Netflix is known as the market leader in the streaming business. However, since 2019, Netflix has been losing subscribers in the United States and is at a turning point where it needs to reassess its current position in the market. While Netflix is losing dominance, rivals Amazon Prime and Hulu continue to gain market shares. Studies from Deloitte and PricewaterhouseCoopers indicated a new shift in the streaming landscape caused by the abundance of streaming options and rising subscription costs. Recent surveys showed that consumers are excited about new streaming services, such as Disney +. Nearly two-thirds of consumers intend to terminate or downgrade one or more of their current subscriptions to make room for a new service. Moreover, it seems that consumers want ad-supported options. In Deloitte's latest Digital Media Trends survey, 65% responded that they would watch ads to eliminate or reduce subscription costs. Seventy percent of Hulu's subscribers choose its lower-priced ad-supported plan. NBC recently launched its own streaming service, Peacock, with a free ad-supported option. This opposes Netflix's brand identity of "no ads" and premium differentiation. With increasing pressure from competition and the growing risk of subscriber loss, Netflix needs to diversify its price plans. The company could try implementing the lower-priced mobile-only plan they are currently testing or plan to test in other regions. Netflix should also consider features or benefits for loyal subscribers to maintain a stronger consumer base.

In deriving the economic order quantity (EOQ) formula, it is tacitly assumed that the buyer has to pay product price while receiving the product from the supplier. However, as a marketing policy, some suppliers permit a delay in payments to the buyers to increase demand for the product they made. Credit transactions would have a positive effect on both suppliers and buyers. For a supplier who offers trade credit, it is an effective means of price differentiation to increase the demand for the product. Availability of opportunity to delay the payment in buyer effectively reduces the cost of holding stocks and therefore, the buyer has a lot of price options to choose his sales price for a customer. Since the buyer's order is affected by the customer's demand, the problems of determining the sales price and EOQ are interdependent and must be solved simultaneously. From this perspective, this paper evaluates the problem of determining the optimal sales price and EOQ for the buyer at the same time when the supplier allows a delay in payments for the product whose demand is represented as a function that decreases linearly with the sales price. For the analysis, it is also assumed that inventory is exhausted not only by customer's but also by decay.

The paper demonstrates that versioning of digital products occurs more frequently than that of physical products because of low marginal cost. The versioning occurs no matter what a customer knows his/her reservation price. Low-quality version will not be produced when the difference between reservation prices is very large. The paper also shows that a firm tries to lower the quality of low-quality product to prevent customers with high reservation prices from purchasing low-quality product.

Price discounts presupposing churn-in are important tools of competition in many industries such as mobile telecommunication services and newspaper. In this case, consumers can get discount only through changing the provider. For analyzing this kind of competitions, we should consider the incentive of utilizing iterative switching. Hence, in this paper, we consider multi-stage equilibrium and can find that equilibria are different from one stage discount. In particular, when consumers' decisions are for maximizing multi-stage utility, discounts can bring about churn-out as well as churn-in and firms lose the incentive of discounts.

The purpose of the current study is to investigate the underlying reasons of fashion brand repurchase intention formation based on means-end chain theory and to identify whether the price level moderates the relationships between attribute evaluation and re-purchase intention. Questionnaire data from 291 consumers who had purchase experience of casual wear during the last 6 month period through off-line retail shops were analyzed. The results showed that hedonic shopping value had a positive impact on aesthetic attribute and utilitarian shopping value also had a positive impact on physical attribute of fashion product. While aesthetic attribute had a positive influence on brand repurchase intention, physical attribute had no effect on brand repurchase intention. In addition, there was no moderating effect of price level between the links from shopping value to fashion product attribute evaluation. When casual wear companies have to devise price related strategies, they need to pay attention to diverse promotion factors except for product attributes to realize price-based differentiation.

The aim of this study was to analyze the perceptions and entering status of small business online fashion retailers on portal shopping and fashion shopping malls. Case studies were conducted on a total of 10 research samples. The results were as follows: first, regarding the strategic factors of online fashion stores, 'price competitiveness' is important, especially in portal shopping and low-cost brands; 'product assortment' is important but not essential in all platforms; and 'differentiation' is important to continuously secure loyal customers in fashion shopping malls. Customer satisfaction leads to customer loyalty, and customer loyalty affects the sales conversion rate and brand growth of online sales channels. Factors that promoted sales activities in online sales channels were exposure, advertisements, SNS, events, special exhibitions, and events. Hindrance factors were low price competition, overheated competition, and the MD of sales channels. Second, the research samples used multiple online sales channels, including portal shopping malls and fashion shopping malls, in addition to their own malls. The selection factors were platform reputation and commission, branding, and customer inflow through exposure. Portal shopping malls were perceived as providing easy access, advertising/customer communication, exposure/search, price competitiveness, scalability, and intense competition, whereas fashion shopping malls were perceived as providing a brand image and concept, brand promotion, high commissions, difficult entry, and low profits. The factors for success in portal shopping malls were exposure/search, price competitiveness, and brand recognition, whereas the factors for success in fashion shopping malls were differentiation, brand, exposure/advertisement, product assortment, and MD.

This study is an exploratory research on the brand architecture of Korean apparel enterprises and the differentiation strategy among in-house competing brands. For data analysis, secondary data was used. 20 apparel enterprises were used as the subjects. The results are as following. First, as a result of brand architecture composition, apparel enterprises used the strategy that initially paved the way launching several brands in a specific item category and after that diversified to other categories. Most enterprises used the multi-brand strategy operating plural brands in a same zoning. The terms for launching succeeding brands were about $1{\sim}5$ years. Second, as a result of analysing the cases which several brands competes within a same zoning, all the posterior brands had some differences from the prior ones. The most frequent differentiation factor was price. Concept, target age, and distribution channel followed. The order of the factors was somewhat different among the item categories. The differentiation strategy among in-house competing brands meant that the enterprises manage plural brands in a same zoning for the growth of whole market share instead of the direct competition among in-house brands. The results of this study can suggest a growth direction to the enterprises planning to launch new brands.
