Abstract

We relate innovation to sales growth for incumbent firms in four high-tech sectors. A firm, on average, experiences only modest growth and may grow for a number of reasons that may or may not be related to 'innovativeness'. However, given that firms are heterogeneous and that growth rates distributions are heavy-tailed, it may be misleading to use regression techniques that focus on the 'average firm'. Using a quantile regression approach, we observe that innovativeness is of crucial importance for a handful of 'superstar' fast-growth firms. We also discuss policy implications of our results.
