Abstract

Mehmet Ugur and Nawar Hashem aim to contribute to the debate by investigating both partial and combined effects of corporate governance and market concentration on innovation. Utilising a dataset for 1,400 non-financial US-listed companies and two-way cluster-robust estimation methodology, they report several findings. First, the relationship between market concentration and innovation is non-linear. Secondly, the relationship has a U-shape in the case of input measure of innovation (research and development - R&D – expenditures); but it has an inverted-U shape when net book-value of brands and patents is used as output measure of innovation. Third, corporate governance indicators such as antitakeover defences and insider control tend to have a negative partial effect on R&D expenditures but a positive partial effect on net book-value of brands and patents. Finally, when interacted with market concentration, anti-takeover defences and insider control act as complements to market concentration.
