This paper presents a model of involuntary product recall in which a f
irm has private information on its ability to produce safety. The ex p
ost regulation of safety is motivated through a parametric imperfectio
n in the product liability system which results in a firm under intern
alizing expected liability expenses. We treat the problem as one of me
chanism design, where the regulator designs a recall procedure. This f
ramework illuminates the point that recall is an interesting blend of
ex ante and ex post regulation. We characterize a perfect recall proce
dure, contrast this with real world imperfect procedures, and study th
e interaction of the recall and the liability systems. Further, we ana
lyze the interaction between optimal recall policy and product market
structure.
