Customer population management models can be classified into three categories: the first category includes the models that analyze the customer population at cohort level; the second one deals with the customer population at aggregate level; the third one has interest in the interactions among the customer populations in the competitive market. Our study proposes a model that can analyze the dynamics of customer population in consumer-durables market at aggregate level. The dynamics of customer population includes the retention curves from the purchase or at a specific duration time, the duration time expectancy at a specific duration time, and customer population growth or decline including net replacement rate, intrinsic rate of increase, and the generation time of customer population. For this study, we adopt mathematical ecology models, redefine them, and restructure interdisciplinary models to analyze the dynamics of customer population at aggregate level. We use the data of previous research on dynamic customer population management at cohort level to compare its results with those of ours and to demonstrate the useful analytical effects which the precious research cannot provide for marketers.

The sales of consumer durables are composed of first time purchases and replacement purchases. Since the sales for most mature durable products are dominated by replacement sales, it is necessary to develop a model incorporating replacement component of sales in order to forecast total sales accurately. Several single product diffusion models incorporating replacement demand have been developed, but research addressing the multi-product diffusion models has not considered replacement sales. In this paper, we propose a model based on consumer choice behavior that simultaneously captures the diffusion and the replacement process for multi-product relationships. The proposed model enables the division of replacement sales into repurchase by previous users and transition purchase by users of different products. As a result, the model allows the partitioning of the total sales according to the customer groups (first-time buyers, repurchase buyers, and transition buyers), which allows companies to develop their production and marketing plans based on their customer mix. We apply the proposed model to the Korean automobile market, and compare the fitting and forecasting performance with other Bass-type multi-product models.

식품의 구입, 조리, 소비에서 편의성과 신속성을 찾는 소비자의 니즈 증대로, 조리가 간단하고 가정식을 대체할 수 있는 가정편의식(HMR) 제품 관련 시장이 매년 성장하고 있다. 또한, 전자상거래를 통한 구매 편의의 증대로 온라인 또는 모바일을 통한 HMR 구입이 증대되고 있다. 기업의 입장에서 구매 만족도를 높이기 위해 소비자들의 불만족 원인과 사후반응에 대한 분석이 필요하다. 하지만 온라인과 모바일을 통해 제품을 판매하는 기업이 직접 불만을 표현하지 않는 소비자의 불만 분석을 수행하기는 비대면 거래의 특성으로 인해 어렵다. 따라서 본 연구는 SPSS와 R을 이용하여 온라인, 모바일을 통해 HMR을 구매해 불만족한 경험이 있는 20대를 대상으로 소비자 특성, 불만족 요인, 불평행동 방식, 재구매 의도 간의 영향 관계를 살펴보고자 한다. 또한, 연구에 구성된 불만족 요인에 대해 직접 경험하지 않았더라도 지각되는 불만의 정도를 분석하여 그 관련성을 알아보고자 한다. 기존 HMR 연구에서 거의 다루어지지 않았던 소비자 불만족 연구를 확장하고, 기업의 불만 관리를 위한 소비자에 대한 이해도를 높임으로써 이에 따른 시사점을 제공한다는 점에서 본 연구의 의의가 있다.

After the onset of the COVID-19 pandemic, there has been an explosive increase in restaurant meal delivery or takeout. The purpose of this study was to analyze the consumer perception of food safety and its influence on the purchase of delivery or takeout food from restaurants. This study, the 2020 Consumer Behavior Survey for Food (CBSF), was conducted from June 10 to August 21 2020. A total of 6,355 responses were used for the analysis. The results were as follows: First, the differences in consumer perception about food safety were analyzed according to whether they used delivery or takeout. Concern about food safety, satisfaction with dietary habits, and the ability to maintain safe dietary habits were higher in the non-user group. Except for food at home, the perception about food safety at other locations was higher in the user group. Food hazards such as antibiotics were perceived to be safer in the user group. Second, the perception of food safety affecting use of delivery or takeout was analyzed. It was found that the usage of delivery or takeout increased when the perception of the safety of home meal replacement (HMR), delivery or takeout food, and the ability to be informed about the harmful factors of agricultural products increased. The findings of this study may offer the basis for the food and food service industry to consider safety issues seriously and develop strategies to lead to feasible practices. Further, this study also supports the direction of the government toward strengthening the safety of new segments which have shown explosive growth in the COVID-19 era.

Objectives: Nail salon owners in New York City (NYC) are required to provide their workers with gloves and it is their responsibility to maintain healthy, safe working spaces for their employees. The purpose of this study was to determine the frequency with which nail salon workers wear protective gloves. Methods: A Freedom of Information Law request was submitted to New York Department of State's Division of Licensing Services for a full list of nail salons in Manhattan, NYC. A sample population of 800 nail salons was identified and a simple random sample (without replacement) of 30% (n=240) was selected using a random number generator. Researchers visited each nail salon from October to December of 2015, posing as a potential customer to determine if nail salon workers were wearing gloves. Results: Among the 169 salons in which one or more workers was observed providng services, a total of 562 workers were observed. For 149 salons, in which one or more worker was observed providing services, none of the workers were wearing gloves. In contrast, in six of the salons observed, in which one or more workers was providing services, all of the workers (1 in 2 sites, 2 in 1 site, 3 in 2 sites, and 4 in 1 site) were wearing gloves. Almost three-quarters of the total number of workers observed (n=415, 73.8%) were not wearing gloves. Conclusions: The findings of this study indicate that, despite recent media attention and legislation, the majority of nail salon workers we observed were not wearing protective gloves when providing services.
