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

Therefore,to guide consumers to rational consumption,some optimizing measures can be taken to improve its utilization efficiency on their purchase decision. This paper plans to explore,through modular modeling method,the main factors that could determine the influence of IWOM on consumers' purchase orientation. It is divided into three key parts. The first part studies the status of IWOM through a mathematical modeling. Part Two probes the solutions. The third part tries to verify with an empirical case the effect of the model in improving the advantage of the positive feedback relationship between the IWOM and its utilization efficiency.展开更多
