    Solution Preview

    In Cournot competition firms compete in quantities and tend to maximize their profit. Counot model predicts that firms choose Nash equilibrium.

    Let
    q1 = output of Firm A
    q2 = Output of Firm B.

    Total Output Q=q1+q2

    P = equilibrium price

    P=100-2*(q1+q2) = 100-2q1-2q2

    Consider Firm A

    Total Revenue for Firm A, ...

    Solution Summary

    Solution describes the steps to determine equilibrium price and quantity of two identical firms in the case of cournot duopoly.
