Under Stackelberg competition, firms compete over quantities of production. But unlike Cournot competition, the firms do not make these decisions simultaneously. Instead, a leading firm begins by choosing its quantity. Then a following firm sees that opposing quantity and chooses its own. This lecture goes through the technical details of solving for the equilibrium production of a duopoly under Stackelberg competition. 0:00 Stackelberg Model Setup 1:49 Solution Strategy 4:06 Firm 2's Best Response 5:36 Firm 1's Equilibrium Production 7:50 Firm 2's Equilibrium Production
