We investigate the effect of a vertical merger on downstream firms' ability to collude in a repeated game framework. We show that a vertical merger has two main effects. On the one hand, it increases the total collusive profits, increasing the stakes of collusion. On the other hand, it creates...

This study constructs a model of anticompetitive exclusive contracts in the presence of complementary inputs. A downstream firm transforms multiple complementary inputs into final products. When complementary input suppliers have market power, upstream competition within a given input market...

We construct a two-period model of the supply chain's openness in a durable goods market by introducing two marketing modes: leasing and selling. Given a marketing mode, at the beginning of the first period, an incumbent supplier and the downstream monopolist choose one of the trading modes: (i)...

A manufacturer contracting secretly with several downstream competitors faces an opportunism problem, preventing it from exerting its market power. In an infinitely repeated game, the opportunism problem can be relaxed. We show that the upstream firm's market power can be restored even further...

We analyze the effects of downstream firms’ acquisition of pure cash flow rights in an efficient upstream supplier when all firms compete in prices. With an acquisition, downstream firms internalize the effects of their actions on their rivals’ sales. Double marginalization is enhanced....

This paper provides theoretical explanations for devices that movie distributors use to avoid head-to-head competition. We use a simple static model to show how revenuse sharing exhibition contracts providex multiplex owners with incentives to take cross effects on demand into account. Then we...

We investigate the possibility for two vertically related firms to at least partially collude on the wholesale price over an in.nite horizon to mitigate or eliminate the e¤ects of double marginalisation, thereby avoiding contracts which might not be enforceable. We characterise alternative...

We investigate the incentive for partial vertical integration, namely, partial ownership agreements between manufacturers and retailers, when the retailers are privately informed about their production costs and engage in differentiated good price competition. Partial vertical integration...

At present, there is a wide debate on regulating geo-blocking, an online practice that prevents consumers from buying or having access to products and services from another country. This practice is not only used by retailers, but is also of great importance in the market for digital visual...
