This paper shows that the provision of consumer rights can induce unintended distributional effects and may, under specific circumstances, even decrease welfare when some consumers are unaware of these rights. We find that consumers who are uninformed about a mandated warranty may demand excessively safe products when the share of informed consumers is high. In other circumstances, uninformed consumers buy the efficient or an inefficiently unsafe products like informed consumers, but the former cross-subsidize the latter via firms’ pricing. Concerning the salient policy option of improving information about consumer rights, we find that increasing the share of informed consumers may raise the risk of inefficiency.
