Freedom and Rationality as Predictors of Cross-National Happiness Patterns: The Role of Income as a Mediating Variable

Freedom and rationality have traditionally been viewed as essential ingredients to the 'pursuit of happiness'. Previous research has found that the way in which happiness is linked to freedom and other attributes of individualistic society is affected by the income level. This paper formulates a structural model of the linkage between political freedom, rationality, and happiness which takes explicit account of income as a mediating variable. Since income is hypothesized to be linked to the degree of freedom and rationality prevailing in a society, this approach permits to distinguish between direct and indirect linkages of happiness to freedom and rationality. Estimating the model with cross-national data yields the following key findings: (1) Happiness is positively related to freedom as well as to rationality at high freedom/rationality levels and negatively at low levels. (2) Whereas freedom affects happiness only indirectly (through its impact on income), rationality has both direct and indirect effects on happiness.
