Knowledge externalities affect high and low growth firms differently. This paper develops two theoretical arguments. The knowledge equilibrium argument postulates that knowledge externalities weaken high growth firms for the benefit of low growth firms until performance differences vanish. The knowledge competition argument proposes that high growth firms are better positioned to identify, attract, and integrate knowledge, thereby expanding the performance gap between high and low growth firms. Based on 188,936 observations of 32,736 Swedish firms from 2004 to 2011, it is analysed whether knowledge externalities enable high growth firms to surge ahead or low growth firms to catch up.
