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.

<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.

The efficiency of any entrepreneur is a function of personal production skill, knowledge and experience acquired over time and exposure via training in the field of his or her enterprise focus. It is on this premise that this study examined the effect of extension training on technical efficiency of maize farmers in Ogbomoso Agricultural Zone, Oyo State, Nigeria. Multistage sampling procedure was adopted for the selection of One-hundred and Eighty-One (181) maize farmers, while structured and validated interview schedule was used to obtain necessary information from the sampled respondents. Data collected were analyzed using both descriptive and inferential statistical tools. The mean age of sampled farmers was 48 years and majority (80.1%) of the farmers was male. The farmers with extension contact have access to different extension trainings on maize production in the study area. The average household sizes were 7 and 8, with the average farm sizes of 1.423ha and 1.417ha for both contact and non-contact maize farmers respectively. Those farmers with extension contact were found to be technically efficient than non-contact farmers. Significant relationship existed between some selected socio-economic characteristics of both sampled maize farmers and their maize output. The study therefore suggests the need to create more awareness on the roles of extension services on crop production among farmers and the authorities concern with extension service delivery should improve on the frequency of extension contact in order to encourage farmers' participation in extension activities in the study area and rural communities in Nigeria at large. Keywords: Extension training, technical efficiency, contact and non-contact maize farmers.

Cocoa is an important crop to the economies of countries such as Nigeria, Cote D’Ivoire, Ghana and Cameroon in West Africa. This study ascertained the adoption levels of farmers in cocoa rehabilitation programmes in South West, Nigeria. Data for the study were collected from 240 cocoa farmers through the use of interview schedule and focus group discussion. Multistage sampling procedure was used in selecting respondents. Data were analysed using percentage and mean statistics. Results revealed that, adoption index was high in planting young cocoa seedlings under old cocoa trees for the three groups of farmers - farmers that benefitted from government agency cocoa resuscitation programme (98.0%), farmers that benefitted from non-governmental agency cocoa resuscitation programme (94.0%) and farmers that benefitted from both governmental and non-governmental agencies cocoa resuscitation programmes (95.0%). Low adoption index (38.0%, 32.0% and 33.0%) were recorded in coppicing technique for the three groups of farmers, respectively. The most helpful agency in the adoption of cocoa resuscitation programmes was Agricultural Development Programme (M=2.80). To improve the level of adoption of cocoa resuscitation programmes, Federal Government of Nigeria through Ministry of Agriculture should provide more incentives geared towards encouraging increased participation of the organized private sector in cocoa production.

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.

This study used 23 factors (eight interval variables and 15 dummy variables) as proxies for health depreciation. We used 1248 older adults from the Center for Geriatrics and Gerontology of Taichung Veterans General Hospital (Taiwan) to examine the association among frailty, health depreciation, and mortality in older adults. This study found that a significant positive correlation existed between frailty and mortality in older adults. Further, we applied a recursive bivariate probit model to examine the association between health depreciation factors, frailty, and mortality. Our results showed that health depreciation factors, such as Charlson’s comorbidity index, diabetes and hyperlipidemia, significantly increased older adults’ frailty; in contrast, albumin and mini nutritional assessment significantly decreased older adults’ frailty. Through the frailty regression, we confirmed not only that health depreciation factors significantly influenced mortality, but also that creatinine, myocardial infarction, and malignant tumors could directly and significantly increase older adults’ mortality.

In this study, we explored the willingness to pay (WTP) for broilers raised under the high welfare system. The interval data model and the ordered probit model were used to investigate the factors that affect consumers’ WTP for broiler meat produced by farm animal welfare (FAW), practice. Our results from both methods suggest that socioeconomic characteristics such as education level, income level, gender, and age significantly affect consumers’ WTP. The food safety concerns of consumers and perceived consumer effectiveness also influence consumers’ WTP. Using the interval data method, we computed the mean and median of the estimated WTP from our survey sample. The mean was 46.7745 New Taiwanese dollar per kilogram. The marginal effects of the different variables are also presented.

AbstractUsing a recursive bivariate probit model and survey data covering the period 2014–2018, the present paper aims to assess which factors in the financial market (supply side) have a higher impact on firms’ likelihood to be financially constrained. The results show that after controlling for potential endogenous bias due to unobservable firm characteristics, being an innovative firm increases the probability of being financially constrained between 21 and 32%. The nature of the innovation strategy also seems to influence the severity of financing constraints. For financially constrained firms, the main factors that limit future financing for growth ambitions are the lack of collateral, bureaucracy, and too high a price. Findings also indicate that measures to facilitate equity investments and making existing public measures easier are the most important factors for future financing while tax incentives only play a minor role.
