The deep determinants of heterogeneity.

Notes: This figure illustrates the relationship between the long-run country-specific coefficients (plotted in Figure 3) and deep-rooted institutional and human characteristics. It shows a fitted linear regression line for the relationship between democracy coefficients and several fundamental factors, including genetic distance to the USA (Spolaore and Wacziarg 2009), ancestry-adjusted predicted genetic diversity (Ashraf and Galor 2013), ancestry-adjusted state history (Borcan, Olsson, and Putterman 2018), and the timing of the Neolithic Revolution (Putterman 2006).
