Assume that two interior design companies, Alistair and Baine, are competing for customers and, if they both advertise, they would each earn $30 million in profits. If neither advertises, they each earn $50 million in profits. If one advertises and the other doesn't, the firm that advertises earns $40 million in profit while the other earns $20 million in profit.
