“…Our study contributes to three strands of literature. First, this work contributes to a better understanding of the HC phenomenon (e.g., Audretsch et al, 2018Audretsch et al, , 2020Benz et al, 2021;Lehmann et al, 2019) and shows that the HC strategy can indeed lead to stronger financial performance as measured by ROA. Second, as HCs are an important part of the German Mittelstand, our study also contributes to the broader literature on the (German) Mittelstand (e.g., Berghoff, 2006;Block & Spiegel, 2013), particularly its success factors (De Massis et al, 2018).…”
