Design effect is often used in designing and planning sample surveys and/or in evaluating the efficiency of complex design features of the surveys. In this study, we applied Gabler et al. (2006)'s design effect model to 2013 Consumer behavior survey for food that was carried out by stratified two-stage sampling. Usability and adequacy of the design model to a real survey data are discussed and evaluated.

For this purpose, first, external surrounding factors of the apartment are extracted and then classified into three major design categories (instinctive, behavioral, and reflective design), and each factor is evaluated by the emotional evaluation. The scope of the research is restricted to the apartments in Daegu city which are built by Top 3 construction companies from the analysis of construction-working rank (May, 2010). The residential-expenditure data are extracted from D-univ. students, in accordance with the satisfaction of the external surroundings and emotional-reaction against the emotional-design factors of the apartment.

The purpose of this study was to conduct an empirical survey on consumer perception and consumption behavior in relation to local food and eco-friendly food. The survey was conducted using 266 consumers who have heard about or purchased local foods and eco-friendly foods centering on Seoul and Gyeonggi-do, and statistical analysis was carried out using SPSS (Version 23.0) to generate descriptive statistical values such as frequency and percentage and implement a Chi-square test. The results showed that consumers purchased local food in large shopping malls, supermarkets, and local food stores, whereas eco-friendly food were usually bought in large shopping malls, supermarkets, and eco-friendly food specialty stores. For local food, consumers bought fruits the most, followed by vegetables, whereas for eco-friendly food, consumers purchased vegetables the most, followed by fruits. The top reason for purchasing local food was its "fresh and high quality," whereas the top reason for buying eco-friendly food was "safety from pesticides and additives." According to results of the Chi-square test, women, unmarried people and younger people turned out to have more experiences in purchasing local foods and eco-friendly foods compared to men, married people and older people, respectively. Although local and eco-friendly food were completely different concepts, results of the study show that consumers were not able to make a clear distinction between the two. Consumer education, therefore, should involve defining the two types of food and spreading awareness on local and organic food to help them made the right choices when buying food.

The transfers were paid in cash for welfare recipient households, which accounted for 12.9% of all households. Using a survey data, it is found that the cash transfers are mostly used for consumption expenditure, and 21.7 percent of the cash transfer used are spent on additional consumption not originally planned. The consumption response to cash transfers is greater in households that experienced job or income loss because of Covid-19.

A green market for a product refers to the market where the more willingness to pay for the product consumers have, the greener is the product. As the green markets begin to spread out, researches have been carried out mostly on the effects of various environmental policy measures such as unit emission standard, environmental taxes as they are applied in the green markets. This paper focus on a different issue in the green markets, that is, the effects of the greener market on pollution emission. We consider two kinds of markets, which are fully or partially covered. In the fully covered market where the products sold are necessities such that all consumers purchase the product, as the market gets greener, the amount of pollution emission decreases. On the other hand, in the partiaily covered market, it is shown that the amount of pollution emission could increase as the market becomes greener. This critically depends on whether the total output decreases or increases as the market turns greener.

The purpose of this paper is to empirically identify whether unit bias exists or not under the flat rate pricing in the Korean mobile telecommunication market and to give the desirable form of pricing plans for minimizing this irrational behaviors. Our results show that with the flat rate pricing consumers tends to make more voice or data traffic over their optimal consumption level, meaning the existence of unit bias in the Korean mobile market. These results imply that under the current pricing plans subscribers may pay higher monthly fee than their optimal cost which maximizes their utility, for using the telecommunications service. Thus, policy makers need to consider adopting mobile operators' segmentation of the flat rate pricing plans for the reduction of subscribers' telecommunications costs and the improvement of consumer welfare.

In this study, using the raw data of the 7th Food Consumption Behavior Survey(2019), compare and analyze what factors affect the food delivery service and take-out food expenditure of single-person and multi-person households. It was found that women(especially women in single-person households), have a high tendency to pursue safety preference versus price. In the future, Korea's population structure is expected to steadily increase single-person household and elderly households, and women's participation in economic activities is expected to continue to increase. In addition, the food delivery market has more than doubled compared to the previous year in 12 cities and provinces out of 17 cities and provinces nationwide with Covid-19, especially in the non-capital area, making it has become a universal service nationwide. Therefore, the growing home meal replacement market needs marketing strategies to secure and emphasize food safety.
