This paper analyzes the tradeoff between the screening benefit of market power and the
traditional pricing distortion in a framework in which entrepreneurs have multidimensional
private information. Figure I illustrates the basic idea. Consider two equally costly innovations,
with demand curves D2 (“me-too”) and D1 (“major”). Because willingnesses to pay are small,
“innovation D2” creates little social value despite its large market size and does not justify
the fixed cost c of bringing it about. An example might be Netscape Navigator during the
1990’s which, while widely adopted, sold at a low price because it offered little added value
over its rivals. In contrast, America OnLine (AOL), depicted by innovation D1 in Figure I
had a smaller customer base (σ1 < σ2) but brought substantial value to its consumers (and
charged a correspondingly high price).
