Asymmetric Bertrand Duopoly. Two firms compete in Bertrand price competition by simultaneously choosing prices p1, p2. Firm i's production costs when it produces qi are ciqi , which satisfy 0 c1 < c2. Market demand is given by Q = 100. If firm i charges the lowest price it captures the whole market (qi = 100), and if they charge the same price they evenly split the market demand (qi = 50)
