The article focuses on the regulation problems raised by two specific
characteristics of research and development: first, that it is normall
y desirable that several units pursue the same goal, and second, that
only the best of the final products made by these units is worthwhile
to society. When firms have private information, these characteristics
are seen to generate a substitution effect which in some situations i
mplies that the resources allocated to R&D under asymmetric informatio
n are excessive relative to the full-information allocation. I thus id
entify asymmetric information as one possible source of excessive allo
cations to research and development.
