This paper attempted to identify the key factors which potentially contributed to the farmers' willingness to participate in the new-form of the rural cooperative finance organizations sponsored by the Chinese governments. In the process, a total of 442 farmer households as well as small-micro farming enterprises were sampled from the villages in Panjin municipality of Liaoning Province in China, where the new form of the rural cooperative finance organization(NFRCFO) experiment was under way. Those potential factors were classified into the four categories, including the characteristics of the famer households, the reputation of the rural finance cooperatives, transaction costs paid, as well as service quality. A discrete Logit model was used for parameter estimations. The results showed that most of the factors being considered exhibited statistically significant effects on the farmers' willingness to take part in NFRCFO, but with each presenting different levels of impacts. The causes and effects for those uncovered empirical results were fully discussed following by policy implication discussion.展开更多

A conjoint analysis was done in this study on the survey of 975 chicken consumers in the Niger Delta Region of Nigeria, between March and September, 2014 to valuate consumers, preferences and willingness to pay (WTP) for various chicken attributed parts, production method, processing method, storage method, the presence of flavor and cooking method. The estimates of consumers, WTP premium prices for various mixtures of value-added characteristics were ascertained. The consumers preferred chicken products refrigerated, from chicken produced under free-range management, chicken breast, chicken product that was addictive and flavor free, which could be oven-heated or pan heated. One half of the entire respondents were willing to pay about 25% more for value-added chicken product over the price for conventional products. On the whole, a premium for value-added chicken products was more likely to be paid for by young consumers, consumers who patronized farmers' markets and preferred free-range or organic chicken products. WTP by consumers was negatively affected by price of products. The poultry industry could utilize combined knowledge of consumers' WTP for value-added chicken product price as a guide of develop innovative value-added chicken products.展开更多

Probit model was applied to identify the significant factors which influenced our dependent variable "not willing to participate". The results of the analyses showed that crop insurance premium was the most influencing factor which had positive and significant impact on dependent variable. Similarly dissatisfaction with crop loan insurance scheme, lacking of knowledge about crop insurance, believing of being against Islamic rules and time taking process was also found to be positive and significantly influenced the dependent variable. While limited decision power and limited perils were not found to be significant in the results.展开更多
