Abstract

The paper provides a theoretical framework to analyze the effects of Protected Designation of Origin (PDO) labeling on quality choices and welfare. Our model distinguishes two attributes of goods: gustatory quality, which is a search attribute, and geographical origin, which is a credence attribute. We compare equilibria with no label, "non-binding labeling" (i.e. when no requirement on production methods is binding to get the PDO label) and "binding labeling". We find that the PDO good is not necessarily the high-quality good. When it is, the introduction of non-binding labeling causes a decrease in quality. Restrictions on production methods are warranted to maintain the quality level of the labelable good, but they adversely affect the PDO firm.
