Coalition formation of oligopolistic firms for information exchange
This paper investigates the coalition formation of oligopolistic firms for exchanges of information about their cost functions in a game- theoretical framework. An oligopolistic market under uncertainty is considered in which each firm knows its own cost function but not those of all the others. The following results are shown. It is profitable for each firm to exchange the information about cost functions with other firms. When the uncertainty levels of the cost functions of all firms are symmetric, it is of common interest for them to exchange their information by forming the grand coalition. On the other hand, when their uncertainty levels are highly asymmetric, firms possessing less uncertain cost functions come into conflict with one another when exchanging information exclusively with the most uncertain firms. As a result, more than one coalition may be formed among firms.
