| Abstract: |
This paper studies the impact of cooperative R&D and advertising on innovation
and welfare in a duopolistic industry. The model incorporates two symmetric
firms producing differentiated products. Firms invest in R&D and advertising
in the presence of R&D spillovers and advertising spillovers. Advertising
spillovers may be positive or negative. Four cooperative structures are
studied: no cooperation, R&D cooperation, advertising cooperation, R&D and
advertising cooperation. R&D spillovers and advertising spillovers always
increase innovation and welfare if products are highly differentiated and/or
spillovers are sufficiently high. The ranking of cooperation settings in terms
of R&D, profits and welfare depends on product differentiation, R&D spillovers
and advertising externalities. Firms always prefer cooperation on both
dimensions, which is socially beneficial only when advertising and R&D
spillovers are sufficiently high. |
