Professor EJ Mishan was a world expert on the idea of externalities. In this paper, we provide evidence for the intuitive idea of “emotional externalities”. These might be viewed as psychological spillovers from the well-being of one person upon the well-being of another. A new form of laboratory experiment is implemented. “Happiness” answers are elicited in the first few seconds of the experiment. Tragic life events — like family illness and bereavement — are then studied. The paper documents evidence consistent with a powerful caring-about-others effect. The paper’s results also suggest an approximate equivalence between life-satisfaction data and happiness data. Statistical offices should incorporate questions to capture people’s life evaluations, hedonic experiences and priorities … All these aspects of subjective well-being (cognitive evaluations, positive affects and negative affects) should be measured separately to get a satisfactory appreciation of people’s lives. Which of these aspects matters more, and for what purpose, is still an open question. Stiglitz et al., Commission on the Measurement of Economic Performance and Social Progress, 2009
