Dr. Heinz Welsch researched Subjective well-being in Europe. The abstract, as available on http://econpapers.repec.org/article/oupoxecpp/v_3a63_3ay_3a2011_3ai_3a1_3ap_3a71-93.htm:
This paper studies the macroeconomic performance of the EU-12 member countries over 1990–2002 from the point of view of the subjective well-being (life satisfaction) of the citizens. The paper uses data for over 50,000 individuals and controls for personal characteristics (especially income and employment status). Life satisfaction is found to be negatively associated with the unemployment rate and inflation, but positively associated with the growth rate. In contrast to earlier findings, the weights placed on inflation and unemployment are of a similar magnitude. The life satisfaction regression is used to determine the weights to be attached to growth, employment, and price stability in a macroeconomic performance index. It is found that the overall macroeconomic performance ranking of the countries is robust across alternative specifications of the index.
