We test whether predictions of the Aghion et al. (Aghion, P., Bloom, N., Blundell, R., Griffith, R. and Howitt, P. (2004) Competition and Innovation: An Inverted U Relationship. NBER Working Paper series, No. 9269.) model are supported by firm-level data. In particular, we analyze if there is an...

We test whether predictions of the Aghion and Howitt (2004) model are supported by firm level data. In particular, we analyze if there is an inverted U-shaped relation between competition and R&D. Results show that the inverted U-shaped relation is supported by the Herfindahl index but not by...

This paper analyses determinants of firm R&D and if predictions from the model of creative destruction is supported by data using matched employer-employee longitudinal data on the Swedish manufacturing industry. In particular, we analyse the impact of competition on R&D. Using various measures...
