Industrial Organisation — Entry, Exit & Predatory Pricing

Run a three-firm Costarian beverage industry through the full entry / fight / exit cycle. Surface barriers, contestability, predation and the war of attrition. Three rounds: Tropico's entry decision (Mercurio NPV under three incumbent reactions), Helio Verde's accommodate-vs-fight decision (Areeda-Turner, Brooke Group, AKZO, Wanadoo), and Tropico's exit-or-pivot decision (sunk-cost fallacy and Bulow-Klemperer war of attrition).
