摘要

(1) The stationary levels of R&D and quality for the open-loop strategies are socially optimal.

(2) The stationary feedback levels of R&D, quality, consumer surplus and social welfare are always lower than their open-loop counterparts; the opposite then is true with regard to firms’ prices and profits.

(3)  Product differentiation does not impact the stationary levels of R&D and quality under the open-loop model, but it negatively affects the stationary levels of R&D and quality under the feedback model.

(4) R&D investment remains higher for a firm with an initial   quality advantage during the market evolution; however, the levels of R&D and product qualities of the two firms will ultimately converge to stationary points.
