Is the high-tech sector becoming less dynamic like the broader economy?
Core argument: The gap between U.S. High Tech and national firm entry rates fell below one percentage point in 2018, an all-time low, down from 5 to 6 percentage points in the 1990s.
Although the High Tech sector still remains more dynamic than the non-High Tech sector of the economy, the gap between the two has gradually faded. Beginning with firm entry rate, we see a long-running decline in both the High Tech sector and the broader economy. The national firm entry rate, hitting a series high of 13.5 percent in 1984, fell below 10% during the Great Recession and has yet to recover. The High Tech sector saw much higher startup rates during the 1980s, peaking at 17.9%, also in 1984. High Tech industries saw another huge surge in new startups in the 1990s, coinciding with the dot-com boom, but their startup rates have yet to recover. In 2018, the gap between the national and High Tech startup rates fell below one percentage point to an all-time low, down from 5 to 6percentage points in the 1990s. The rate of new firm creation in the High Tech sector, once far ahead of other sectors, now looks similar to that of the increasingly sclerotic national economy.
