We model networks of relational (or implicit)contracts, exploring how sanctioning power and equilibrium conditions change under different network configurations and information transmission technologies. In our model, relations are the links, and the value of the network lies in its ability to...

Following Bernheim and Whinston (1990), this paper addresses the effects of multimarket contact on firms ability to collude in repeated oligopolies. Managerial incentives, taxation, and financial market imperfections tend to make firms objective function strictly concave in profits and market...

It has been argued that having a contract market before the spot market enhances competition (Allaz and Vila, 1993). Taking into account the repeated nature of electricity markets, we check the robustness of the argument that the access to contract markets reduces the market power of generators....

The paper addresses the effects of the separation of ownership and control on long-run competition in oligopolies. It finds that when managers have the preference for smooth time-paths of profits revealed by the evidence on "income smoothing," manager-led firms can sustain any collusive...

This paper analyzes a finite horizon, sequential move pricing duopoly, restricting attention to Markov-strategies. The solution yields stationary patterns, independent of initial conditions, where the reaction-functions follow cycles of three periods. The market price never settles down, and is...

This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

Both proximity-concentration trade-off and factor proportions explanations have been forwarded to explain the existence of multinational enterprises. This paper analyses to what extent these different explanations are supported empirically, in making a first attempt to distinguish explicitly...

This paper analyses the effects of the Single European Market and Swedish Investment liberalisation on the structure of Swedish multinationals with their EU affiliates. The empirical results suggest that the determinants associated with horizontal and vertical multinationals have become...

This paper develops an adverse selection model of mixed bundling. By packaging its product with a competitively produced good unrelated in demand, a monopolist can induce self-selection of different types of consumers into buyers of the bundle and of the separate components. Private and social...

"Destructive Creation" is the deliberate introduction of new, perhaps improved generations of durable goods that destroy, directly or indirectly, the usage value of units previously sold inducing consumers to repeat their purchase. This paper discusses this practice by a single seller in an...
