Most firms do not grow, and a small number of high-growth firms seem to create most new jobs. These firms have therefore received increasing attention among policymakers. The question is whether high-growth tends to persist? We investigate this question using firm-level data from Sweden during 1997–2008. We find that high-growth firms had declining growth rates in the previous 3-year period, and their probability of repeating high growth rates was very low. Thus, these are essentially “one-hit wonders,” and it is doubtful whether policymakers can improve economic outcomes by targeting them.
