Competition and private R&D investment

Area of Science:

• Economics
• Industrial Organization
• Innovation Studies

Background:

• Understanding firm R&D investment is crucial for economic growth and competitive strategy.
• Rival firms' R&D decisions significantly impact a company's own investment strategies.
• Existing models often simplify the complex interplay of competitive factors in R&D.

Purpose of the Study:

• To determine the factors influencing the direction of rival firms' R&D reaction functions.
• To develop a theoretical model explaining R&D investment based on competitor actions.
• To empirically validate the model using data from large manufacturing corporations.

Main Methods:

• Utilized a two-stage n-firm Cournot competition game to model firm interactions.
• Developed a dynamic panel data model to analyze R&D investment decisions.
• Accounted for the endogeneity of rival firms' R&D efforts.

Main Results:

• Identified four distinct environmental types (based on product rivalry and technology spillovers) that dictate the sign of R&D reaction functions.
• Empirical results strongly supported the predictions of the theoretical model.
• Demonstrated that firms' R&D investments are significantly influenced by the R&D efforts of representative rival firms.

Conclusions:

• The study provides a robust framework for understanding strategic R&D investments in competitive markets.
• The findings highlight the critical role of market structure and knowledge spillovers in shaping innovation.
• The validated model offers valuable insights for corporate strategy and policy-making in innovation-driven industries.
