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...

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 inefficiently high prices for spare parts. Furthermore, monopolization induces the...

We analyze the listing decisions of a retailer who may ask her suppliers to make upfront payments in order to be listed. We consider a sequential game with upfront payments being negotiated before short-term delivery contracts. We show that the retailer is more likely to use upfront payments the...

This paper examines how delivery tariffs and private quality standards are determined in vertical relations that are subject to asymmetric information. We consider an infinitely repeated game where an upstream firm sells a product to a downstream firm. In each period, the firms negotiate a...
