Optimal Sharing of Foodborne Illness Prevention between Consumers and Industry: The Effect of Regulation and Liability

Abstract

Consumers and the food industry can both prevent foodborne illness. Two questions are explored: what is the socially optimal level of preventative effort by each and can tort and regulatory instruments induce such behavior? Analysis is complicated by two aspects of food safety technology: one party's effort can affect the marginal effectiveness of the other party's effort and damage functions can be nonconvex. Previous analysis of accidents under torts and regulation fails to consider these generalizations. Indeed, results concerning the ability of tort and regulatory instruments to induce first‐best and second‐best behavior often contradict previous results in the literature.
