Can consumer complaints reduce product reliability? Should we worry?

Abstract: We analyze a monopolist’s pricing and product reliability problem when consumers are entitled to product replacement but have heterogeneous cost of exercising this right, and we assess the implications of a decrease in consumers’ claiming cost on reliability, pro?t, and welfare. We ?nd that reducing consumers’ claiming cost may reduce reliability and increase pro?t. Additionally, the model can explain why some ?rms encourage consumers to complain while others discourage consumers can explain why some ?rms encourage consumers to complain while others discourage consumers sumers’ claiming cost are relatively low and the ?rm prefers to promote complaints; consequently we ?nd that encouraging complaints will eventually increase welfare.
