Does the source of billionaire wealth determine productivity growth?
Core argument: A one-standard-deviation rise in billionaire founders' aggregate wealth relative to GDP is associated with a 1.87-percentage-point increase in total-factor productivity growth over the following seven years.
I demonstrate that inequality impedes economic efficiency when it arises from rent-seeking by entrenched elites. However, I also show that inequality can be beneficial when driven by creative destruction. A one-standard-deviation increase in the ratio of billionaire founders' aggregate wealth to GDP is associated with a 1.87-percentage-point (ppt) rise in total-factor productivity (TFP) growth over the next seven years. In contrast, a one-standard-deviation increase in billionaire heirs' wealth ratio correlates with a 1.28-ppt decline in TFP growth over the same period. Further the positive relationship between founders' wealth and TFP is stronger in more financially developed countries. By contrast, consistent with the rent-seeking equilibrium, the negative relationship between heirs' wealth and TFP is more pronounced in countries that are less financially developed, less open to foreign capital, and less democratic. One way to [further] identify the sources of wealth driving inequality might be to examine the institutional settings that enable the rich to amass their fortunes.
