The purpose of this paper is to introduce a new category of goods, indeterminate goods, which will be compared with the classical framework of experience, search and credence goods (Nelson, 1970; Darby and Karni, 1973). This concept sheds new light on the nature and status of quality uncertainty through the following hypothesis: uncertainty about the product's quality can be shared by all agents of the market, and this uncertainty can be non-neutral and disrupt the market. We identify three types of shared uncertainty about the product's characteristics and the corresponding problems that can arise: shared uncertainty due to the emergence of a product (Hirschman, 1974), shared uncertainty concerning the past of a product (basing ourselves on the art market), and finally shared uncertainty regarding the future impacts of a product, through empirical data on product safety.
Key Words: Product quality Quality uncertainty Shared uncertainty Indeterminate goods Radical uncertainty
