Abstract
|
|
|
|
|
This paper introduces the time dimension into the
precompetitive R&D model, where both demand and
spillovers vary over time. The effect of cooperation on
R&D depends on a weighted function of spillovers, with
the weights being a function of demand levels. The bulk of
the incentives for innovation come from the growth phase
of the industry.
