論文提要 |
In this paper, we develop
a differentiated duopoly model with endogenous cost-reducing R&D and
review the argument on welfare effect of price and quantity competition in
the presence of technology licensing. We show that, with
licensing, the standard conclusion on duopoly (Singh and Vives,
1984) is completely reversed. Cournot competition
induces lower R&D investment than Bertrand competition does. Moreover, Cournot competition leads to lower prices, lower industry
profit, higher consumer surplus and higher
social welfare than Bertrand competition. |
