Real GDP per capita (thousands of dollars, log scale)
Notes:Well-being data are aggregated separately for each indicator in each survey by running an ordered probit regression of happiness or
satisfaction on country fixed effects. Dashed lines are fitted from OLS regressions of this well-being index on log GDP. Real GDP per capita
is at purchasing power parity in constant 2000 international dollars.
