Packaging, Selection, and Correlated Firm Behavior

Many firms do not charge separately for services such as delivery, parking, and acceptance of payment cards (‘packaging’). I show that for a range of service costs, multiple equilibria arise and each firm chooses to offer a service if and only if its competitors offer the service as well. Intuitively, no firm is willing to be a sole offerer of the service even when offering the service is efficient: the offering firm serves disproportionally many service users, which constitutes ‘bad’ selection when service costs cannot be recovered separately.
