The historical analogies of this paper suggest that the Internet will evolve in a similar way, towards simplicity. The schemes that aim to provide differentiated service levels and sophisticated pricing schemes are unlikely to be widely adopted. Price and quality differentiation are valuable tools that can provide higher revenues and increase utilization efficiency of a network, and thus in general increase social welfare. Such measures, most noticeable in airline pricing, are spreading to many services and products, especially high-tech ones. However, it appears that as communication services become less expensive and are used more frequently, those arguments lose out to customers' desire for simplicity.
Flat rates are the simplest form of pricing.
Although they have generally been regarded as irrational, and economically and socially undesirable, they have serious advantages. Consumers like them, and are willing to pay extra for them. Further, flat rates are extremely effective in stimulating usage, which is of advantage in a rapidly growing service like the Internet.
