This paper first introduces an approach relying on market games to examine how successive oligopolies do operate between downstream and upstream markets. This approach is then compared with the traditional analysis of oligopolistic interaction in successive markets. The market outcomes resulting...

This paper identifies the optimal two-period price sequence in the attempt for selling a good, with take-it-or-leave-it offers, when the seller faces ambiguity about the buyers' willingness to pay. If the first round fails, the seller updates its beliefs on the state of the market in accordance...

An example is provided identifying a case of inefficiency arising from the interplay of the voting mechanism and the market mechanism.

This paper analyses how the level of social protection is determined when its choice depends on political competition. First this is done under autarky. Then the analysis is extended to take account of the existence of an international capital market. We show that social protection never...

This paper investigates how an incumbent monopolist can weaken potential rivals or deter entry in the output market by manipulating the access of these rivals in the input market. We analyze two polar cases. In the first one, the input market is assumed to be competitive with the input being...

In this paper, we propose an example of successive oligopolies where the downstream firms share the same decreasing returns technology of the Cobb-Douglas type. We stress the differences between the conclusions obtained under this assumption and those resulting from the traditional example...
