ABSTRACT__________________________________________________________

Innovative activities have public good characteristics in the sense that the cost of producing, say, the first
unit of a new good is high compared to the cost of producing subsequent units. Moreover, knowledge of
how to produce subsequent units is often widely known once the innovation has occurred and is, therefore,
non-rivalrous. The main question addressed in this paper is whether mechanisms can be found which exploit
market information to provide appropriate incentives for innovation. We consider environments in which
agents other than innovator receive the signals about the quality of innovation. For example, information
from innovators, competitors, and the marketplace can be used to reward the innovator. If such mechanisms
are used, the innovator has strong incentives to manipulate market signals. We show that if an innovator
cannot manipulate market signals, then the efficient levels of innovation can be uniquely implemented without
deadweight losses—for example, by using appropriately designed prizes. We show that patents are necessary
if the innovator can manipulate market signals.
