Abstract

We investigate the optimal R&D portfolio of a single-product monopolist investing in cost-reducing activities accompanied by efforts improving the quality of its product. There emerges that the firm s relative incentives along the two directions are conditional upon market affluency, measured by consumers willingness to pay for quality, and R&D efforts are complements at equilibrium. We also perform the stability analysis, showing that a stable branch exists along the quality dimension only.
