How concentrated are national productivity gains among a few firms?
Core argument: Fewer than 100 firms out of a sample of 8,300 large companies — dubbed Standouts — accounted for roughly two-thirds of positive productivity gains in each of Germany, the UK, and the US.
We apply the economic definition of labor productivity as real gross value added (GVA) per worker, which is very different from profitability or efficiency and includes the impact of employees moving across firms. We look at 8,300 large firms covering 2/3rds of GVA in Germany, the UK, and the US. Fewer than 100 firms in our sample of 8,300, a group that we have dubbed Standouts, accounted for about 2/3rds of the positive productivity gains in each of the countries. Standouts are defined as firms that added at least one basis point to their national sample’s productivity growth. The number of firms that were responsible for the largest drags (negative contributions of at least one basis point) on productivity growth—we call them Stragglers—was even smaller. Only 55 Stragglers accounted for 50 to 65% of the firm-level productivity drag in the three-country samples. In the US, 44 Standouts—5% of sample firms, accounting for 23% of employment share—generated 78% of positive productivity growth. And 14 Stragglers—2% of sample firms, accounting for 10% of employment—were responsible for 57% of negative growth.
