When Sony released the PlayStation 4, it was reported that Sony was taking a loss of $60 on every PS4. However, Sony expected to make this up with sales of PS+ subscriptions and increased royalties from video games. Use the interdependence principal to explain this strategy. The PS+ subscription allows PS4 owners to play their videogames online, receive new games monthly to download at no charge and receive additional special discounts on other items. Therefore PS4 and PS+ subscriptions are ____________________ in consumption. Decreasing the price of PS4 will __________________ the demand for PS+ subscriptions. Sony expects that revenue from recurring PS+ subscriptions will be larger than the loss in revenue from PS4 sales.

Andrew, a college student, loves drinking coffee late at night to study for exams. Having no income, he is used to buying cheap, bad tasting coffee such as Bean lightened, that he needs to grind and brew himself. The coffee tastes putrid but, with enough cream and sugar, Andrew is able to tolerate it. Occasionally, he does go out to Starbucks when he has spare money.
