"This paper demonstrates that institutional factors have differential impacts on subjective well-being of individuals in rich versus poor countries. A lower level of corruption, a more democratic government and better civil rights increase the well-being of individuals in rich countries, whereas an increase in per capita income has no impact. On the contrary, in poor countries the extent of corruption, democracy or civil rights has no influence on happiness, but an increase in per capita income impacts happiness positively. We provide evidence that this stark contrast may be due to the difference of preferences over economic growth and institutional factors."
