The Journal of Industrial Economics, Volume 74, Issue 3, Page 316-331, September 2026.ABSTRACT We study optimal simple rating systems that partition sellers into a finite number of tiers. We show that optimal ratings must be threshold partitions, and that for linear supply and Cournot competition with constant marginal cost, optimal thresholds solve a k‐means clustering problem requiring only the quality distribution.

Cournot-Walras equilibrium as a subgame perfect equilibrium [PDF]
In this paper, we investigate the problem of the strategic foundation of the Cournot-Walras equilibrium approach. To this end, we respecify à la Cournot-Walras the mixed version of a model of simultaneous, noncooperative exchange, originally proposed by

Analytic solutions of nonlinear Cournot duopoly game
Discrete Dynamics in Nature and Society, 2005 We construct a Cournot duopoly model with production externality in which reaction functions are unimodal. We consider the case of a Cournot model which has a stable equilibrium point.

It reveals that when environmental performance (EP) incentives prevail, sales performance (SP) incentives depend on the emission tax type and competition ...
