<p>The study was conducted to address the issue of consumers’ willingness to pay for inclusion of cassava flour in bread in Lagos State. The data were collected randomly from a sample of 300 respondents in the state through the use of a well structured questionnaire. The contingent valuation method was adopted to estimate both the mean willingness to pay of consumers and the factors that affect their willingness to pay and these were analyzed using the bivariate probit model. The most significant model was the 10percent cassava flour inclusion as it has the highest number of significant variables (eight) followed by 20percent cassava flour inclusion with seven significant variables and 30 and 40percent cassava flour inclusion with six significant variables each. The factors that influenced consumers’ willingness to pay for CCW bread were the respondent’s age, gender, respondents’ awareness, married respondents, respondents with head position<em>,</em>and bread share which is the<em> </em>proportion of respondents income spent on bread to total income. The mean willingness to pay for bread with an inclusion of cassava flour at 10, 20, 30, and 40percent cassava flour inclusion were ?172.70, ?165.00, ?154.07, and ?142.78 respectively for initial bid while the mean willingness-to-pay at 10, 20, 30, and 40percent cassava flour inclusion were ?180.20, ?150.41, ?143.35, and ?127.36 respectively for subsequent bid. Arising from the result of this study, birth control policies were recommended among respondents in the study area.</p>

Willingness To Contribute

Church forests provide a safe habitat for plants and animals, sources of food and traditional medicine, seed bank for native tree species, reduce soil erosion and rich in biodiversity. But the economic values of these important benefits of church forests were not well documented. Therefore, this study was conducted to estimate the mean and total willingness to pay for church forest conservation using open-ended and double bounded contingent valuation formats. In doing so, both cash and labour contributions were used to measure the respondents’ willingness to pay. Primary data were collected from 300 randomly selected households and analyzed using descriptive statistics and bivariate probit model. The estimated mean willingness to pay from the double bounded format (239.79 Ethiopian Birr) is higher than from the open-ended format (178 Ethiopian Birr). Similarly, the estimated mean willingness to contribute labour was also 71.51 and 94.34 man-days for the open-ended and double bounded contingent valuation format, respectively. The comparison indicated that the mean and total willingness to pay from the double bounded format is higher than in the open-ended format. Therefore, researchers, policymakers, and forestry experts should give special attention to the double bounded format rather than to the open-ended format to elicit respondents’ willingness to pay for the conservation of church forests.

Moringa oleifera is a nutritious tree plant that has several uses. Moringa leaves contain Vitamin A, Vitamin C, Calcium, Iron, Potassium, and it has good quality protein.  Moringa leave could be used in treating malnutrition. It also contains antioxidants which could help in treating certain diseases. This study examined the factors influencing awareness and willingness to pay for moringa. A multistage sampling procedure was used in selecting the respondents.  Data were analyzed using Recursive Bivariate Probit Model. The result shows that mean age of respondents was 44 years and the mean household size was 5. The result further revealed that 80.5 percent of the respondents were aware of moringa while 80.1 percent were willing to pay for moringa. The result of the model of awareness of moringa revealed that awareness increases willingness to pay for moringa (p<0.01). The factors that influences awareness were age and occupation of the respondents, knowledge of the nutritive benefits of moringa, perception of respondents that moringa vegetable is too expensive and respondents preference for other vegetable while the factors that influences willingness to pay for moringa were occupation of the respondents, knowledge of other uses of moringa, respondents perception that moringa vegetable is sweet,  non availability of fresh moringa vegetable and respondents preference for other vegetable. There is need to increase the awareness of nutritive benefits of moringa vegetable and encourage the availability of fresh moringa foe sale in the local markets.

The study was conducted primarily to 1) identify the socio-economic and the knowledge, attitude and perception (KAP) factors that affect the WTP of the households; 2) determine the socio-economic factors affecting the KAP of households; and 3) determine the mean willingness to pay (WTP) of households of four barangays of Lemery, Batangas: Mataasna Bayan and Sinisian East as on-site barangays and Balanga and Sinisian West as off-site barangays of the Marine Protected Area (MPA). A total of 316 respondents were surveyed following the contingent valuation method (CVM). Results showed that the mean WTP of the respondents amounts to PhP 46.47 per month. Among factors influencing their WTP are KAP variables such as knowledge on MPA, knowledge on MPA as fish habitat, perception on the need of MPA protection led by the Barangay, perception if there is anything to be changed in MPA management, and socio-economic variables like gender, income-expenses ratio and distance from the MPA. Using the mean WTP, the computed social benefit derived by the on-site and off-site MPA communities from coral reef conservation-based from their WTP amounted to PhP 999,215.734 per year.

The study was carried out to determine the willingness to pay (WTP) for Biofuel gel among households in Lagos State, Nigeria. A total of one hundred and seventy-five households using multiple sampling procedure were interviewed using a well-structured questionnaire. Data were analysed using descriptive statistics and Logit regression model. The study showed that the mean willingness to pay for Biofuel gel was ₦280 (US $0.78) per litre. The study further revealed that there was significant relationship between the socio-economic characteristics of the households and their willingness to pay for biofuel gel. Variables such as bid amount and household income had significant effect on the willingness to pay for biofuel at 1%. Bid amount had a negative coefficient of -0.0233655 on willingness to pay for biofuel gel. The study therefore recommends that price policies can be implemented in the form of price subsidies to foster the consumption of biofuel gel (clean fuels) in the study area, as respondents are more sensitive when it comes to their wallets and had identified high cost of the product as a major constraint for not consuming biofuel gel.

Background: The study objective was to investigate the willingness to pay (WTP) for teledermoscopy services among students at a university health center. The hypothesis was that WTP for teledermoscopy among students would exceed the costs for traditional consultation. Methods: Between November 2013 and May 2014, students at a university health center were surveyed for their perceptions of teledermoscopy. One set of responses was collected from students visiting the health center for any reason (anonymous sample). An additional set of responses was collected from students visiting for dermatologic lesions (in-person sample). A contingent valuation method with a maximum likelihood estimation procedure was used to estimate the WTP distribution. Results: A total of 214 surveys were collected for the anonymous sample and 41 responses for the in-person sample. The mean (standard deviation [SD]) WTP for the anonymous sample was $55.27 ($39.11; 95% confidence interval [CI]: $49.99-$60.55). The mean (SD) WTP for the in-person sample was $52.37 ($26.56; 95% CI: $43.99-$60.75). Median WTP for the 2 samples was similar: $48.84 and $48.01. Conclusions: We conclude that students would be willing to pay for teledermoscopy services that would provide the potential for significant system cost savings. This may be especially true in college health or similar settings where dermatology services may not be available.

-The case study examines the economic aspects of cultural heritage conservation and deals the valuation of economic value in monetary terms, using the application of the contingent valuation method to the castle of Nicastro (Catanzaro, Italy). For the construction of the hypothetical market and the selection criteria and approach to subjects of the statistic sample, the proposed solutions work with operative adjustments, dictated by the characteristics of the resource in question and in general for all cultural resources. The study has produced reliable answers to questions of willingness to pay, expressing the measure of the different components of the value (use value and existence value) contribute to the composition of the total economic value. The study allowed to verify the possibility of using the contingent valuation as a political tool. The particular question format, which combines ‘double bounded dichotomous choice' and ‘open ended' techniques has allowed us to take a sensitivity analysis, defining the measure of willingness to pay.Key words: evaluation cultural resource, contingent valuation method, willingness to payParole chiave: valutazione, beni culturali, metodo di valutazione contingente, disponibilitŕ a pagare

The contingent valuation method was used to estimate willingness to pay (WTP) for the operation and maintenance of an improved water source in the villages of Kigisu and Rubona in rural Uganda. The survey was conducted in August 2011 and administered to 122 households out of 400 in the community, gathering demographic information, health and water behaviors, and using an iterative bidding process to estimate WTP per 20 L for a public tap. The data were analyzed using an ordered probit model, which predicts monetary intervals for households' WTP. The model predicts a mean WTP of 356 Ugandan shillings (USD 0.183) per 20 L from a public tap. It was determined that the number of children in the home and the distance from the existing source are significant in influencing household's WTP, while income, age, and gender are not.

This study aimed to estimate the willingness of households to pay for domestic clean water use against its price in rural areas of Cang Long district, Tra Vinh province. This research also identified the possibility and factors affecting the willingness to pay for a given price of 6,500 VND or above per m3 of clean water. A contingent valuation method with multiple prices (bidding game) ranging from VND 5,000 to VND 9,000 per m3 of clean water was applied to interview 120 households in Cang Long district. Results showed that the mean willingness to pay was VND 6,200 for each m3 of clean water used. The income positively affected the willingness to pay against the price of 6,500 VND or above whereas the household size had a negative impact on this parameter. It is suggested that the service provider should consider to extent the minimum volume of water used up to 10 m3/month instead of 4 m3/month in accordance with the minimum price of 5,700 VND per m3 of water used.
