In this case, the situation is a classic duopoly. Two shipping firms are in a price war over the market for containerized shipping to and from a small Caribbean island. The case presents a table of contributions to both firms as a function of their prices. This table serves as a basis by which the class can explore the concepts of Nash equilibrium, price leadership, and prisoner's dilemma. It is also available with the case as a student spreadsheet (QA-0355X). See also ''Lesser Antilles Lines (B)'' (UVA-QA-0641) and ''Lesser Antilles Lines (C)'' (UVA-QA-0670).
