摘要：We analyze the effects of accidents and liability obligations on the incentives
of car manufacturers to monopolize the markets for their spare parts. We show
that monopolized markets for spare parts lead to higher overall expenditures for
consumers. Furthermore, while the manufacturers invest more in order to offer
cars with higher qualities, monopolization tends to reduce social welfare. Key
for these results is the observation that high prices for spare parts entail a
negative external effect inasmuch as liability obligations imply that consumers
of competing products have to pay the high prices as well.
