We analyze two-part tariffs in oligopoly, where each firm commits to a certain quantity. The model is an extension of the one introduced in Harrison and Kline (2001).We show that their main results are reversed when the model is extended from one to two types of consumers.

Two TV channels compete on programming with respect to both time schedule (continuous choice) and programme progile (discrete choice), with a directional constraint concerning time schedule (viewers cannot watch TV before they get home). We show how the relative importance of programme progile...
