We reconsider the problem of cartel stability in a linear symmetric Cournot oligopoly by assuming that every coalition of firms defecting from a cartel can choose its quantity before the remaining firms. We show that differently from [5] the only profitable cartel includes all firms in the industry. This result is shown to be robust to nonlinearity of the profit function, provided that the inverse demand function is not too log-concave.

Abstract
We reconsider the problem of cartel stability in a linear symmetric Cournot oligopoly by assuming that every coalition of firms defecting from a cartel can choose its quantity before the remaining firms. We show that differently from [5] the only profitable cartel includes all firms in the industry. This result is shown to be robust to nonlinearity of the profit function, provided that the inverse demand function is not too log-concave.File allegati a questo prodotto
