This paper examines, from the perspectives of the agency-theoretic approach, how ownership concentration impacts technological innovation. We conduct this analysis by allowing the effect to vary according to the identity of the main shareholder and test several hypotheses by employing survey...

Better understanding the innovative process of renewable energy technologies is important for tackling climate change. Though concentrating solar power is receiving growing interest, innovation studies so far have explored innovative activity in solar technologies in general, ignoring the major...
