Is the world of Swedish CEOs a meritocracy?

Renee B. Adams, Matti Keloharju, and Samuli Knüpfer have a new paper:

This paper analyzes the role three personal traits — cognitive and non-cognitive ability, and height — play in the market for CEOs. We merge data on the traits of more than one million Swedish males, measured at age 18 in a mandatory military enlistment test, with comprehensive data on their income, education, profession, and service as a CEO of any Swedish company. We find that the traits of large-company CEOs are at par or higher than those of other high-caliber professions. For example, large-company CEOs have about the same cognitive ability, and about one-half of a standard deviation higher non-cognitive ability and height than medical doctors. Their traits compare even more favorably with those of lawyers. The traits contribute to pay in two ways. First, higher-caliber CEOs are assigned to larger companies, which tend to pay more. Second, the traits contribute to pay over and above that driven by firm size. We estimate that 27-58% of the effect of traits on pay comes from CEO’s assignment to larger companies. Our results are consistent with models where the labor market allocates higher-caliber CEOs to more productive positions.

In other words, Swedish CEOs are a pretty impressive lot.  Scott Sumner offers some related remarks on American CEOs.
