Sacks, Stevenson and Wolfers (2010) question earlier results like Easterlin’s showing that long-run economic growth often fails to improve individuals’ average reports of their own subjective well-being (SWB). We use World Values Survey data to establish that the proportion of individuals reporting happiness level h, and whose income falls below any fixed threshold, always diminishes as h increases. The implied positive association between income and reported happiness suggests that it is possible in principle to construct multi-dimensional summary statistics based on reported SWB that could be used to evaluate economic policy.
