Stackelberg Model of Duopoly Stackelberg Duopoly Suppose that two rms (Firm 1 and Firm 2) face an industry demand P = 150 Q where Q = q 1 + q 2 is the total industry output. Both rms have the same unit production cost c = 30. — If the firms’ total output is = 1 + 2 then the market price is if … An Analysis of the Production Leader in the Stackelberg Model.pdf.

We investigate the (dynamic) stability of a stackelberg oligopoly model of a market of a homogeneous good, with output competition, one Stackelberg leader and a number of identical followers. The principal difierence between the Cournot model and the Stack-elberg model is that instead of moving simultaneously (as in the Cournot model) the flrms now move sequentially. stream >> /Resources 12 0 R Augustin Cournot’s Model Oligopoly was made by the French economist Augustin Cournot in 1839. is model rests upon the following main assumptions: 1. /Length 436 /FormType 1 /Filter /FlateDecode The Stackelberg equilibrium price is lower, so output and total surplus are higher; total profits are lower. 976 A Stackelberg oligopoly is one in which one firm is a leader and other firms are followers. 14 0 obj 5 0 obj Stackelberg model.
