This study investigated the effects of applications of international quality assurance certification at farm level on the implementation of traceability along the shrimp supply chain with evidence from Vietnam. Descriptive statistics was explored to compare products, information flows, financial efficiency, and willingness to implement traceability between certified and noncertified quality assurance shrimp farms. A binary logistics model was applied to examine the effects of applications of international quality assurance certification and other factors on the willingness to implement traceability of shrimp farmers. Found results showed that the applications of international quality assurance certification of shrimp farmers supported traceability of shrimp products among stakeholders in the supply chain. The certified farmers indicated a higher willingness to implement traceability. However, the profitability of those applications for shrimp farmers was not statistically found. The economics incentives, including farm-gate price differentiation and minimization of production costs, should be carefully considered. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the point of view of consumers in developing and emerging market about the genetically modified and non-genetically modified food based on the evidence from soymilk non-genetically modified product. The experimental auction method was employed to explicit the willingness-to-pay of Vietnamese consumers for a non-genetically modified soymilk products. Regression analysis was applied to determine factors influencing consumer's WTP for non-genetically modified product. The results indicated that consumers are willing to pay 84% premium for soy milk with non-genetically modified attribute information in comparison with the conventional one. The level of WTP derived from the auction is not much different from the market price of the product being auctioned. Notably, consumers with high level of risk aversion were likely to purchase non-genetically modified food. This was a predominant factor that determines who would accept or deny the consumption of non-genetically modified food. [ABSTRACT FROM AUTHOR]
