Appropriate policies are needed to guide this transformation, presupposing good understanding of consumer preferences. We analyze consumers’ valuation of different vegetable attributes in metropolitan areas of Vietnam, using contingent valuation techniques and a mediation framework for two specific examples. Consumers are willing to pay an average price premium of 60% for Chinese mustard that is free of chemical residues and of 19% for different convenience attributes of potatoes. Income levels and media have positive impacts on the willingness to pay, partly mediated through consumer perceptions.enjournal_article10.1111/j.1467-9353.2009.01437.x3150289
