Činí nás žárlivost druhých šťasnými?

The relative income is often cited as a reason why happiness of nations does not grow in time with growing GDP. The study replicates the methodology of several different researchers from basic scatterplots, standard OLS and ordered probit models to hierarchical linear multilevel models (HLM). The results provide evidence that the happiness is actually rising with the growing GDP, although slowly and with the GDP measured in logarithm. On the contrary, the relevance of relative income to happiness is ambiguous through all the proposed models. Furthermore, the individual characteristics like marital status or employment status are proved to explain the differences in happiness much better than income. Finally it is shown that income has similar effects on different measurements of subjective well-being (health, happiness and emotional well-being).
