In this paper, we introduce the concept of conjectural variations across sectors called "external conjectural variations" in a pure exchange economy. Three results are obtained. First, the symmetric oligopoly equilibrium coincides with the Cournot equilibrium when the conjectural variations are...

In this note, we introduce conjectural variations in a simple general oligopoly equilibrium model of a pure exchange economy. Three results are obtained. First, the price and utility levels generally increase with the value taken by conjectures. Second, when the conjectural variation takes its...
