Consumers'Willingness to pay for foods with traceability information: Ex-Ante quality assurance or ex-post traceability?

Abstract

In this study, traceability in pork profile information with ex-ante quality assurance and ex-post traceability are constructed. Consumers' willingness to pay (WTP) for traceability information is investigated inWuxi, China, by combining theMultiple Price Lists method and the Becker-DeGroot- Marschak (BDM) experimental auction. The main factors affecting consumers' WTP are also analyzed using a Tobit model. The results demonstrate that consumers have higher WTP for ex-ante quality assurance than for ex-post traceability. The highest WTP is for the ex-ante quality assurance attribute of pork quality inspection. Consumers' WTP for traceability information is influenced by their individual characteristics, including age, education and income, as well as their concern and satisfaction about food safety and confidence in food safety labeling. The contribution of this paper is that it improves the meaning of traceable food information attributes and measures the significance of attributes to consumers. Furthermore, this paper introduces a Becker-DeGroot-Marschak experimental auction method which amends the measurement deviation of hypothetical experiments.
