This study intended to estimate the willingness-to-pay amount by farmers for the automatic guidance technology of Combine. Contingent Valuation Method was employed for this estimation using survey data from 65 Combine using farmers. Based on the dichotomous choice model, farmers’willingness-to-pay for the automatic guidance technology was ranged from ￦4,772,000(median) to ￦5,268,000(mean). The estimated willingness-to-pay by the for the new technology was approximately one quarter of the average value based on the willingness-to-pay for the new technology was approximately one quarter of the average value of Combine in sample farms. This implies that there is an economic rationals for developing the new technology as long as it will be available with the cost less than the amount of estimated willingness-to-pay.

Environmental concern has been an important issue for a few decades, and the extent of consumer demand for eco-friendly consumption has been increased. This study seeks to investigate consumers' willingness to pay (WTP) a premium for eco-friendly cosmetics. This study evaluates how much more a consumer is willing to pay for eco-friendly cosmetics and examines significant factors influencing consumers' WTP for eco-friendly cosmetics. Consumers' WTP is measured using four different ecofriendly cosmetics: low-priced skin care cosmetics, low-priced makeup cosmetics, high-priced skin care cosmetics, and high-priced makeup cosmetics. This study uses the contingent valuation method (CVM) to estimate consumer's WTP for eco-friendly cosmetics. Survey questions were designed using both dichotomous choice and payment card method of CVM. Through face to face interviews and on-line surveys, the data were collected from women between 20 and 49 years old residing in Seoul and Kyeonggi area, Korea, in May 2010. A total of 226 questionnaires (132 from interviews and 94 from on-line) were included for the analytical sample in this study. The data were analyzed using descriptive analysis, T-test and Log-Logit analysis. The findings are as follows: First, the WTP measured by dichotomous choice method was estimated using the Log-Logit analysis. The results showed that the estimated WTP for low-priced skin care cosmetics was 19,152 won, which was 27.7% higher than the reference price, 15,000 won. For low-priced makeup cosmetics, the estimated WTP was 18,524 won, and its green premium was 21.0%. The estimated WTP for high-priced skin care cosmetics was 59,128 won, which was 18.3% higher than the reference price, 50,000 won. For high-priced makeup cosmetics was 57,666 won, and its green premium was 15.3%. Second, the WTP measure by payment card method was estimated using descriptive analysis. The results showed that the respondents were willing to pay 17,955 won for low-priced skin care cosmetics, which was 19.7% higher than the reference price, 15,000 won and 17,595 won for low-priced makeup cosmetics, which was 17.3% higher than the reference price. For high-priced skin care cosmetics, the average WTP was 56,950 won which was 13.9% higher than the reference price, 50,000 won. For high-priced makeup cosmetics, the average WTP was 55,650 won, which was 11.3% higher than the reference price. Overall, the WTP was higher in order of low-priced skin care, low-priced makeup, high-priced skin care, and high-priced makeup. It means that consumers decide degree of premium based on the price and the attributes of eco-friendly products. Third, the findings showed that age, monthly income, and having children or not were statistically significant factors that influenced consumers' willingness to pay for eco-friendly cosmetics. Other explanatory variables such as education, marital status, job, purchase experience of eco-friendly products, and environmental concerns did not show any statistical significance. The major contribution of this study is the investigation of the value of green attributes of the products by using CVM. Unlike most previous researches, this research used two methods of CVM, the dichotomous choice and the payment card, so it enhanced the reliability of research. According to this study, consumers showed price sensitivity when they pay green premium. These findings can be used as useful information to establish marketing strategies for green cosmetics.

The purpose of this study is to estimate the utility value of boat fishing experience marine tourism activity in Jeju Island's Chagwido. The utility value is estimated by single bounded and double-bounded dichotomous choice contingent valuation method. The contingent valuation method is used to estimate economic values for all kinds of coastal ecosystem services. The method involves directly asking people, in a survey, how much they would be willing to pay for specific environmental services. So, the method has great flexibility, allowing valuation of a wider variety of non-market goods and services than is possible with any other non-market valuation technique. This study collects the effective 504 questionnaires from boat fishing experience tourists in Jeju Island's Chagwido. The results show that the average willingness to pay amount(WTP) is estimated to be about 17,000 Korea won by single bounded and double-bounded dichotomous choice contingent valuation method. This indicates that the utility value of boat fishing experience marine tourism activity is estimated to be about 17,000 Korea won in Jeju Island's Chagwido.

PURPOSES : Benefits for improvement of travel time reliability obtained from construction of new highways should be considered as a major factor in the feasibility study for highway constructions. The purpose of this study is to develop a method of estimation for the value of travel time reliability. METHODS : Highway type (urban/rural highway) and traffic flow type(interrupted/uninterrupted) was considered to estimate he value of travel time reliability. And Double-bounded Dichotomous Choice among Contingent Valuation Method(CVM) was applied to survey the willingness-to-pay of drivers when travel time reliability is improved. Finally the value of travel time reliability was estimated using the results of survey and logit model. The value of travel time reliability was estimated considering travel objectives, time constraint travel and non-time constraint travel. RESULTS: The value of travel time reliability of business trip is higher than that of non-business trip. The value of travel time reliability of time constraint travel is higher than that of non-time constraint travel. The value of travel time reliability in urban area is higher than that in rural area. CONCLUSIONS: It was concluded that the proposed method in this study is more realistic and proper to estimate the value of travel time reliability because it reflects the situations of time constraint travel and non-time constraint travel.

In Korea, the industry and marketing of livestock has grown because of increases in consumers' income and changes in food consumption trends. Livestock production and consumption increased tenfold from 1970 to 2018, and this rise will continue. However, the quality of marketing information for Korean livestock has remained low. The Korea Institute for Animal Products Quality Evaluation (KAPE) operates programs that provide marketing information on livestock, but the social benefits of these programs have not been objectively evaluated. The purpose of this study was to estimate the social benefit of the programs offering marketing information on Korean livestock. Survey and analysis using an economic model (double-bounded dichotomous choice contingent valuation model), revealed a few findings. First, the users of the marketing information programs offered by KAPE recognized the value of these programs and demonstrated their willingness to pay for this marketing information. Second, the social values of the programs offering marketing information on livestock were estimated as 1.1 billion won (marketing information on main livestock) or 5.3 billion won (price information on poultry), and these social values were 2 or 6 times greater than the cost to operate the programs for offering information. Finally, the program that provides marketing information on domestic livestock provides sufficient social benefits, so KAPE should expand these programs.
