In Korea, origin labeling is one of the main issues in the food service sector. Many restaurants presented the incorrect or no origin of the food material, and Korean consumers have kept complaining about it. Even though the origin labeling program was welcomed by consumers, the food service sector has claimed that there is an increasing cost due to the origin labeling program. It is an important issue to determine whether the origin labeling program is good for the social welfare; however, the specific effects of the origin labeling program have rarely been measured. The purpose of this study was to measure the effect of origin labeling of beef in the Korean food service sector. Through survey and model analyses, a few findings are presented. First, Korean consumers showed a positive willingness-to-pay for the origin labeling of beef. Especially, consumers without information on the origin of the beef showed a larger willingness-to-pay for the origin labeling. Second, the origin labeling of beef changed the price and quantity of beef, and this change became larger when the consumers had no information on the origin of the beef. The change in the marketing margin due to the origin labeling program also affected the changes in the price and quantity of the beef. Third, the origin labeling of beef increased the social welfare, which is the sum of the consumer surplus and producer surplus. And this increase of the social welfare became larger when the consumers had no information about the origin.

We have provided a variety of domestic construction technology related full-text services through the Construction Technology Digital Library system since 2001. CODIL is a system that services the database related to construction technology data. On the other hand, there is growing demand for DB every year, but the required budget is shrinking. Therefore, this study investigated the satisfaction to effectively service the construction technique-related full-text with a limited budget. The monetary value of full-text to express satisfaction with the quantified value was estimated using the Tobit model. The Tobit model is used as a contingent valuation method to estimate the value of non-market goods. This model is the limited dependent variable regression model to observations by censoring the limit of the left side or right side so that a biased outlier is not reflected in the willingness to pay. A survey was conducted by sampling 312 respondents. The mean, median, truncating the willingness of payment were calculated for the six types of the full-text services using the Tobit model. The statistically significant variables affecting the willingness to pay for the full-text services were identified. The mean value of per the full-text service was estimated to be 46,530 won. The significance of this study was to use the Tobit model to estimate the value of the construction technology-related full-text services for the first time in Korea.

Purpose-Meat plays an important role in the Chinese daily diet, however, due to the spread of COVID-19, food supply and safety have become a major concern. The safety and health features of chilled fresh meat have attracted the attention of consumers. To study consumers' purchasing behavior and willingness to pay for chilled meat under the influence of the epidemic. Research methodology- The data were obtained by questionnaire survey, major issues include consumers' meat consumption habits in the wake of the COVID-19 and their awareness of meat product quality labels. In addition, the gender, age, family income, and other basic personal information of the interviewees were also counted. Based on the binary Logit regression method, we study consumers' purchasing behavior and willingness to pay for chilled meat under different demographic characteristics. Results-The results showed that brand and quality certification are important factors influencing purchases. In addition, the presence of children under the age of 12 in the household and the level of income and education also influence consumers' purchase intention of the chilled fresh meat. However, mart promotions and city ratings can significantly lower consumers' propensity to buy the chilled fresh meat. Apart from this, such factors as gender, age, and living conditions have no significant influence on consumers' purchase of chilled fresh meat.

This paper revisits two conventional beliefs of environmental nonmarket valuation and examines their weaknesses and a new opportunity. The two beliefs are that willingness to pay (WTP) is an appropriate measure of nonmarket behaviour and that exogenous variables are relevant predictors of WTP whilst endogenous variables are not. The contemporary literature in psychology and economics is reviewed to demonstrate departures from these two beliefs. Tackling heterogeneity in stated preferences, both socio-demographic and psychological variables should be measured simultaneously to explain and predict choice behaviours more accurately.

In this paper, we apply fuzzy theory in a discrete choice Contingent Valuation Method(CVM) in order for dealing preference uncertainty problem. Fuzzy membership function is used in an empirical analysis to estimate the willingness-to-pay(WTP) for the preservation of the endangered Asiatic Black Bear in Korea. The estimated WTP was about 9,090 Korea Won per household with 78 percent of confidence level. The advantage of applying fuzzy theory in the valuation method could be found in its ability to measure the confidence level of the estimated WTP.

This study aims to analyze of the impact of converged information with tourism and Bus Information on recreational bus travel. The research has conducted as the following process : A survey was implemented that the user preference behavior as if they were provided a converged information with tourism and bus information on bus usage. As a result, we found that able to using mobile media, having a experience visiting the tourism site, evaluate willingness to pay of the information highly, the 20s age, increasing income variables are concerned with positive relation, and the factors which are using the main mode by auto and having a auto are negative relation on bus usage actively.

The current study examined the influence of individual trait such as Need-For-Touch level (NFT; high vs. low) and swiping orientation (vertical vs. horizontal) on product evaluation and preference when using touch-screen interface like a smart phone and a tablet. Swiping is one of the most common interaction techniques for changing pages or searching some aligned pictures on touch-screen interface and it can be used in vertical and horizontal orientations. The experiment revealed a significant interaction between swiping orientation and NFT on preference, however the interaction on change-in-price of given products was only marginally significant. To be specific, high NFT participants reported higher preference for horizontal-swipe than vertical-swipe products, but such difference did not occur with low NFT participants. The current study illustrates the influence of swiping orientation and NFT on product preference and it provides a new perspective of design principles especially for online shopping websites.

Interest on ocean environment has increased with the development of industrialized activities. Public marine resorces are defined broadly to include fish stocks, beaches, marine waters, recreational fishing, biota, waterfowls, shorebirds, seabirds and marine mammals But, it is not easy to analyze compensation for injury to publicly owned marine resources because the claimants do not exist clearly and the economic methodology of damage on public goods is not developed fully. This paper introduces basic idea of welfare economic theory and environmental legislation to the research question : How the economics and law can be applied to the case of damage on publicly owned marine resource. The paper discusses the concepts of willingness to pay (WTP) and willingness to accept (WTA). It is accepted generally that WTA is correct concept of welfare change in the case of damaged public goods. Four methods (compensating variation, equivalent variation, compensating surplus, equivalent surplus of measuring welfare changes are compared. Compensating variation(CV) is the best measure of welfare changes are compared. Compensating variation(CV) is the best measure of welfare changes caused by environmental damage. Vartia (1983) showed CV could be measured from the ordinary demand function using the differential equations. This paper also provides an overview of the emerging U.S. and Korea legal system for compensation for natural resource damages, with particular emphasis on U.S. legal system under Comprehensive Environmen-tal Response Compensation and Liability Act (CERCLA). These regulations are to include two different types of standardized procedures for assessing natural resources injury : Type A or simplified assessment techniques for small releases ; and Type B protocols that would include detailed and extensive assessment methodologies for major releases. Type A procedures are specified by Natural Resources Damage Assessment Model for Coastal and Marine Environment (NRDAM/CME) of the U.S. CERCLA provides a legal 'legitimization for the use of economic-based nonmarket valuation in the courts and have introduced appropriate and accurate nonmarket valuation methods based on willingness to-pay for damage assessment. By briefly reviewing economic theory and environmental legislation, we hope to help provide a better understanding of the compensation process and the economics of publicly owned marine resources in the U.S. and to integrate the economics and law of natural resources valuation into a single comprehensive package in Korea.

This study tries to quantify the regional NIMBY costs to nuclear power plants. NIMBY costs are estimated as willingness to pays for avoiding nuclear power plants near residential areas through the contingent valuation method(CVM). In the study, it was assumed that the nuclear power plants were newly constructed around the residences. The result of 600 respondents living within a radius of 30 km of nuclear power plants compared to the result of 600 respondents living in the metropolitan area, which revealed that there were significant NIMBY costs to the construction of nuclear power plants in all residences. By region, the willingness to pay in the metropolitan area was greater than that in the nuclear power areas. This study focuses on NIMBY to nuclear power plants from a regional point of view, which can provide important information in establishing prudent and sound nuclear power policies.
