This paper analyzes endogenous merger formation in oligopolistic markets where firms have different unit production costs. We reformulate the merger model, introduced by Barros (1998), by employing the core as cooperative equilibrium concept. We show that, depending on the size asymmetry in the...

In this paper we introduce identifying restrictions into a Markov-switching vector autoregression model. We define a separate set of impulse responses for each Markov regime to show how fundamental disturbances affect the variables in the model dependent on the regime. We go to illustrate the...

In this paper we study nationalizations in the oil industry around the world in 1960-2002. We show, both theoretically and empirically, that governments are more likely to nationalize when oil prices are high and when political institutions are weak. We consider a simple dynamic model of the...

Governments in extraction countries are anxious to estimate expected investment in development projects, since they represent an essential element of the macro economy. The overall level of activity is also crucial to oil companies, since the macro picture affects cost levels, the supplies...

We study coalitional one-deviation principle in a framework a la Chwe (1994). The principle requires that an active coalition or any of its subcoalition will not benefit from a single deviation to a strategy that specifies, for each history of coalitional moves, an active coalition and its move....
