Nash equilibrium bertrand model
WitrynaIn other words, an equilibrium is a pair of quantity choices that satisfy both rms’ reaction functions: qb 1 = r 1(bq 2) and bq 2 = r 2(bq 1): In our numerical example, then, an equilibrium is a simultaneous solution of the two rms’ rst-order equations in (1) and (2), 4q 1 + 2q 2 = 60 and 2q 1 + 4q 2 = 60; if both q 1 and q 2 are positive ... WitrynaBertrand equilibrium is an equilibrium in a duopoly where firms set their prices at marginal costs. Nash equilibrium is an equilibrium in which no firm has an incentive …

Witryna2 cze 2024 · Definition of Bertrand Competition A market structure where it is assumed that there are two firms, who both assume the other firm will keep prices unchanged. Therefore, each firm has an incentive to cut prices, but this actually leads to a price war.

The Nash Equilibrium ( ) in the Bertrand model is the mutual best response; an equilibrium where neither firm has an incentive to deviate from it. As illustrated in the Diagram 2, the Bertrand-Nash equilibrium occurs when the best response function for both firm’s intersects at the point, where .

WitrynaThe Bertrand–Nash equilibrium of this model is to have all (or at least two) firms setting the price equal to marginal cost. The argument is simple: if one firm sets a price above marginal cost then another firm can undercut it by a small amount (often called epsilon undercutting , where epsilon represents an arbitrarily small amount) thus ...
