Abstract
The food sector is considered a mature and a research and development (R&D) extensive industry. Nevertheless, also food companies face numerous challenges and cannot abstain from innovation activity if they want to keep their competitive stance. We examine the impact of innovation on labor productivity in European food companies in comparison to results for firms operating in high-tech sectors. The central motivation of our study is that the observed low R&D intensity in the food sector should be mirrored in different productivity effects of innovation when compared to the high-tech sector. We use microdata from the European Union s Community Innovation Survey (CIS) and apply an endogeneity-robust multi-stage model that has been applied by various recent studies. Our results point out major differences between the examined subsectors. While we find strong positive effects of innovation on labor productivity for food firms, we find insignificant effects in the high-tech sector. This suggests that the returns to innovation might be best evaluated separately by sector rather than for the manufacturing sector as a whole.
