LuLu Restaurant (LR) and Lucy Café (LC) have an implicit agreement to keep prices high so that both can earn $30,000 profit a year. Below is their complete payoff matrix in terms of thousands of dollars of profit per year and strategic actions a and b. LR’s payoffs are the left and LC’s are on the right. However, in 2014 new owner/managers have taken over both LR and LC and have to decide whether to abide by the implicit agreement or to cheat.

You are the manager of the only firm worldwide that specializes in exporting fish products to Japan. Your firm competes against a handful of Japanese firms that enjoy a significant first-mover advantage. Recently, one of your Japanese customers has called to inform you that the Japanese legislature is considering imposing a quota that would reduce the number of pounds of fish products you are permitted to ship to Japan each year. Your first instinct is to call the trade representative of your country to lobby against the import quota. Is following through with your first instinct necessarily the best decision?

- Price competition between firms, from the firms’ perspective, can be similar to the prisoners’ dilemma. The best outcome for all firms would be for all to charge a high price. However, if the other firms charge a high price, any individual firm has incentives to charge a low price and steal the market. Additionally, if any other firm chooses a low price, each firm should charge a low price too so that it doesn’t get priced out of the market. Explain how price-matching (firms announcing a policy where they match the lowest price a customer can find or will honor a competitor’s coupon) can help firms avoid the Nash equilibrium in which they all charge a low price. Is it misleading for a firm to advertise price-matching as being beneficial to consumers? (Hint: What outcomes of the game are ruled out by the price-matching policy? How does ruling out these outcomes change the game and the decision the firms face?)arrow_forwardPrice competition between firms, from the firms’ perspective, can be similar to the prisoners’ dilemma.
