Abstract:Cournot establishes a Nash equilibrium to a duopoly game under output competition; Bertrand finds a different Nash equilibrium under price competition. Both treat the strategic choice variable (output versus price) and the timing of play as exogenous. We investigate Cournot-Bertrand models where one firm competes in output and the other competes in price in both static and dynamic settings. We also develop a general model where both the timing of play and the strategic choice variables are endogenous. Consiste… Show more
“…Because one firm competes in price, efficient bargaining is not possible with the Cournot-Bertrand model. 9 Operationally, the inverse demand Equations (1) and (2) Consistent with the analysis of the Cournot-Bertrand model without a union (Tremblay and Tremblay [16] and Tremblay, et al [8]), our model generates an asymmetric equilibrium where the Cournot-type firm has the strategic advantage (as long as d > 0). Given the high degree of heterogeneity in firm behavior, bargaining costs may be substantially higher in the Cournot-Bertrand model, an issue we take up in the next section.…”

“…As discussed in the introduction, the Kreps and Scheinkman [9] model reflects the idea that firms will prefer price competition when prices are inflexible relative to production. In addition, Tremblay, et al [8] show that the mix of Cournot-Bertrand behavior can be supported when there are suitable demand or cost asymmetries to induce just one firm to behave as a Bertrand competitor. In furniture manufacturing, for example, capacity may adjust relatively slowly for mass-producers, causing them to behave as Cournot competitors.…”

“…In an industry with a relatively fixed-proportion technology, efficient bargaining forces firms to compete in output (as in Cournot). From the firm's perspective, however, there are market conditions under which Bertrand or Cournot-Bertrand competition is preferred to Cournot competition (Kreps and Scheinkman, [9]; Tremblay, et al [8]). If the cost of switching from price to output competition is sufficiently high, these firms will reject Cournot competition and efficient bargaining.…”

Abstract:We investigate the welfare effect of union activity in a relatively new oligopoly model, the Cournot-Bertrand model, where one firm competes in output (a la Cournot) and the other firm competes in price (a la Bertrand). The Nash equilibrium prices, outputs, and profits are quite diverse in this model, with the competitive advantage going to the Cournot-type competitor. A comparison of the results from the Cournot-Bertrand model with those found in the traditional Cournot and Bertrand models reveals that firms and the union have a different preference ordering over labor market bargaining. These differences help explain why the empirical evidence does not support any one model of union bargaining. We also examine the welfare and policy implications of union activity in a Cournot-Bertrand setting.

Studies on information sharing in oligopolies focus on either Cournot or Bertrand markets. We consider a Cournot–Bertrand market where owners provide strategic managerial incentives and can share the details of their compensation contracts. We find that the Cournot firm punishes its manager for sales, whereas the Bertrand firm rewards sales. Both firms share contract information if the firms' products are sufficiently differentiated. However, if product differentiation is low, then either the Cournot firm or the Bertrand firm keeps the contract information private. Mandating information sharing can lead to an increase in consumer and social welfare but harms firms' profits.
This paper analyzes the optimal privatization policy when firms endogenously choose their strategic variable. The level of privatization is shown to determine: (i) the choice of strategic variable, whereby an asymmetric equilibrium could emerge (either Cournot–Bertrand or Bertrand–Cournot); (ii) the stability of equilibrium when the partially privatized firm and the private firm choose quantity and price respectively as the strategic variable; and (iii) the level of welfare, whereby Cournot–Cournot and Bertrand–Cournot games could lead to a greater welfare than the Bertrand–Bertrand model.
