Lytton on Private Third-Party Verification of Product Claims

Tim Lytton has posted to SSRN Private Third-Party Verification of Product Claims:  Lessons from Kosher Certification.  The abstract provides:

Food consumers often desire products with attributes that are not discernable from a product’s appearance. Unscrupulous sellers may be tempted to misrepresent the presence of these “credence qualities.” In response, reputable sellers wishing to distinguish truthful product claims from spurious ones can provide verification using third-party certification. Third-party certification marks on product labels attesting to a wide variety of credence qualities are now commonplace. This chapter analyzes the global system of kosher food certification to develop a general model of reliable third-party verification of credence qualities.
