This paper shows that within-country happiness inequality has fallen in the majority of countries that have experienced positive income growth over the last forty years, in particular in developed countries. This new stylized fact comes as an addition to the Easterlin paradox, which states that...

This paper provides unprecedented direct evidence from large-scale survey data on both the intensity (how much?) and direction (to whom?) of income comparisons. Income comparisons are considered to be at least somewhat important by three-quarters of Europeans. They are associated with both lower...

In the United States happiness, on average, varies positively with socio-economic status; is fairly constant over time; rises to midlife and then declines; and is lower among younger than older birth cohorts. These four patterns of mean happiness can be predicted rather closely from the mean...

This paper studies the mental distress caused by bereavement. The largest emotional losses are from the death of a spouse; the second-worst in severity are the losses from the death of a child; the third-worst is the death of a parent. The paper explores how happiness regression equations might be...

This paper proposes a new unified theory of sociobehavioral forces. The goal of the new theory is to integrate theories describing five sociobehavioral processes - comparison (including justice and self-esteem), status, power, identity, and happiness - bringing under a single theoretical...

Economics ignores the possibility of hedonic adaptation (the idea that people bounce back from utility shocks). This paper argues that economists are wrong to do so. It provides longitudinal evidence that individuals who become disabled go on to exhibit recovery in mental wellbeing. Adaptation...

When a society overthrows a ruler – call the ruler Caesar – what determines whether Caesar is killed or enslaved? This paper presents a model of killing versus enslaving Caesar, based on a new theory which unifies justice, status, and power. The model pertains to societies which value...

This paper examines how the level and dispersion of self-reported happiness has evolved over the period 1972-2006. While there has been no increase in aggregate happiness, inequality in happiness has fallen substantially since the 1970s. There have been large changes in the level of happiness...

The goal of scientific work is to understand more and more by less and less. In this effort, theoretical unification plays a large part. There are two main types of theoretical unification – unification of different theories of the same field of phenomena and unification of theories of...

The “Easterlin paradox” suggests that there is no link between a society’s economic development and its average level of happiness. We re-assess this paradox analyzing multiple rich datasets spanning many decades. Using recent data on a broader array of countries, we establish a clear...
