With an explosive growth of internet and a change of consumer's demand, Post PC is emerging as a substitute for the existing desktop computer and laptop computer. Post PC is a new computer which is portable with wireless networking, cheaper than the existing PCs and specialized in the specific function that consumers want. Furthermore, the shape and the ability of Post PC are dependent on its specific function. The rudimentary Post PCs such as PDA, web-pad and smart-phone are already usable. And in the future, owing to the progress of technologies, the heterogeneity of relate companies and the low entry barrier, various Post PCs will be developed. In this paper, we analyze consumers' willingness-to-pay for Post PC with the attributes such as the portability, the speed of CPU, the data input method (using key board, or notepad etc), the size of monitor and price. To estimating consumers' willingness-to-pay for the attributes of Post PC, we apply a contingent ranking method, which makes the respondents rank hypothetical Post the portability, the speed of CPU, the data input method (using key board, or notepad etc),the size of monitor and price. To estimating consumers' willingness-to-pay for the attributes of Post PC, we apply a contingent ranking method, which makes the respondents rank hypothetical Post PC alternatives featuring various combinations of attributes, to a survey data collected in Korea. Using the estimated willingness-to-pay, we predict the shape and the ability of future's Post PC and draw policy implications for the national and company level R&D strategies.

응답자들에 따라 지불의사액(willingness to pay : WTP) 조사에서 응답한 WTP에 대한 확신도, 즉 선호의 강도가 다를 수 있다. 본 연구는 선호강도의 정도에 대한 정보를 얻기 위해 응답자가 응답한 WTP에 대해 선호강도가 어떤지에 대한 응답을 이끌어 내었다. 선호강도를 반영한 WTP 자료의 분석을 위해 본 논문에서는 Type 3 토빗모형의 적용을 고려한다. 이 모형을 추정하기 위해서는 통상 동분산 및 이변량 정규성을 만족하는 오차항 구조를 가정한 모수적 2단계 추정법을 적용한다. 하지만 이 가정들이 만족되지 않는다면 추정치는 비일치적이게 된다. 동분산과 정규성 가설에 대해 검정한 결과 유의수준 1%에서 두 가정은 모두 기각되었다. 따라서 모수적 Type 3 토빗모형을 추정하는데 요구되는 가정은 너무 제약적이라 할 수 있다. 본 연구에서는 이 모수적 모형에 대한 대안으로 준모수적 Type 3 토빗모형을 적용한다. 분석결과 준모수적 추정은 모수적 추정보다 유의하게 우수하였으며, 더욱더 중요하게는 모수적 모형으로부터 계산된 평균 WTP 추정치는 준모수적 모형으로부터 계산된 것과 유의하게 다름을 알 수 있었다.

Using the developed wedding planner selection criteria scale, this study examined whether wedding planner selection criteria differ according to consumer characteristics such as demographic characteristics and wedding preparation behaviors. The main survey for this study was conducted via the Internet with 295 consumers aged 20-30 living in the Seoul metropolitan area. The data collected from the survey processed and analyzed using the statistical programs SPSS 21.0 t-test. Analyzing how wedding planner selection criteria differ according to consumers' demographic characteristics and wedding preparation behaviors, results shown for the wedding planner selection criteria were all four points on average except for individual characteristics and important sub-factors regardless of the consumers' characteristics, and various results were derived depending on the consumers' characteristics. This study has various practical implications in that it verified the difference in wedding planner selection criteria according to consumer characteristics and determined how much money consumers were willing to play for wedding planners. It is recommended that future studies take various approaches to investigate how wedding planner users are satisfied with or place importance on wedding planner services and conduct empirical using the selection criteria developed in this study to compare influential variables that affect behavior intention and willingness to pay according to consumer type.

In a long-run, a price reduction of shine muscat that is one type of grapes is expected due to an increase of cultivated area. To come up with this problem, expanding exports of shine muscat considering that domestic demand is restricted in Korea. This study investigates the China consumers preference for shine muscat from Korea since exports to China have increased a lot after the quarantine agreement in 2015. Specifically, this paper analyzes a probability of shine muscat exports to China based on willingness to pay (WTP). Moreover, we derive long-run and short-run export strategies for Korean shine muscat. Our results show that a probability of exports to China is high. However, this probability is lowered at the sample of consumers who have the experience of tasted shine muscat. Considering the relative important characteristic for buying shine muscat at the sample of eating experienced consumers in China is sweetness, there is a need to develop cultivation technologies for enhancing sweetness to attain a sustainable development in the grape sector of Korea.

The purpose of this study is to analyze willingness to pay (WTP) for organic agricultural products. To accomplish the objective of the study, a consumer survey was conducted. Based on the pilot survey results, parametric survival model was used to analyze the WTP for organic products. The estimation results showed that the WTP for organic agricultural products is 1.4-fold when compared with the conventional products, which is lower than the current price by about 30 percent. The analytical results also showed that such variables as gender, recognitions for organic agricultural products, and consumers' income have very significant effects on the WTP, and that there are no differences among WTPs by consumption goals. Based on major findings, the most effective countermeasure was suggested for expanding of organic food consumption through the premium reduction of organic products. Reducing the costs of production and distribution, supporting farmers' income by direct payment system were presented. Furthermore, it is needed to allocate more budget for promoting the consumption and distribution of organic agricultural products, and for enhancing conservation of agricultural environment.

This study investigated consumers' perceptions and willingness to pay (WTP) for fruit and vegetables grown using renewable energy such as solar power, geothermal, waste heat from incinerators, hot water from thermal power plants. To this end, this study conducted an online survey of 1,050 consumers in Seoul, Gyeonggi, and the six metropolitan cities, and the main findings are as follows. First, most of the consumers perceived climate change as a serious problem, and 82.8% recognized the government's declaration of carbon zero was appropriate, which means that the government's active response to climate change is important. Second, on the pros and cons of the use of renewable energy when cultivating fruits and vegetables, opinions in favor of solar power were the highest, followed by geothermal heat, waste heat from waste incineration plants, and thermal power generation hot drainage. Third, at least 28.0% to 41.7% of consumers were willing to purchase fruits and vegetables using renewable energy more expensive than fruits grown using fossil energy such as kerosene. This means that the fruit and vegetable market using renewable energy is valuable as a niche market.

This study suggests the dynamic pricing model which reveals the organic relationship between ASP (Application Service Provider) price and the related factors, using system dynamics methodology. Basically, we applied the law of supply and demand for analyzing price changes. Then, we deducted ASP price, focusing on fixed cost and variable cost. We also researched the customer's buying behavior according to version differentiation policy. In the version policy, we set up the proposition about customer's satisfaction and willingness-to-pay, using option system. As a result, this research designed the simulation model which analyzes the changes of the sales according to version differentiations and customer's willingness-to-pay. Through this research, we can find effective version differentiation strategies. This paper also found that the larger the number of package, the greater the demand and customer's willingness-to-pay. The increase of the number of package causes the increase of the sales. The increase of the sale is not exactly relative to the number of package. Drawing S-curve, the sales was increased. This dynamic pricing model suggests the ground that the ASP price changes based on the existing version differentiation theory and the demand of customers can affect the changes of the sales. We expect that this model suggests a clear standard of ASP pricing by combining real cases.

The paper is to estimate willingness-to-pay (WTP) for tap water quality improvement in Busan, using parametric approach in contingent valuation method(CVM). For parametric approach linear logit model and log logit model are employed in double-bounded dichotomous choice format of CVM. For the reliability and the validity of contingent valuation method a survey was conducted for 665 respondents, who were sampled by stratified random sampling method, by personal interview method. The result of mean WTP for the tap water quality improvement in Busan was estimated to be 3,687 won and 3,660 won per month per household, while median WTP being 1,884 won and 1,892 won per month per household, respectively by linear logit model and log logit model. Provided that our sample is broadly representative of the Busan's population, an estimate of the annual aggregated benefit of residential water improvement for all Busan households is approximately 29.7 billion won to 29.8 billion won based on median WTP.
