This paper analyzes optimal pricing for information goods underincomplete information, when both unlimited-usage (fixed-fee) pricingand usage-based pricing are feasible and administering usage-basedpricing may involve transaction costs. It is shown that offeringfixed-fee pricing in addition to a...

Game theoretic modeling involves making assumptions on agents' infinite hierarchies of beliefs. These assumptions are understood to be only approximately satisfied in the actual situation. Thus, the significance of game theoretic predictions depend on robustness properties of the solution...
