The Easterlin paradox is a key concept in happiness economics. It is named for the economist and USC professor Richard Easterlin, who discussed the factors contributing to happiness in a 1974 book chapter. Easterlin argued that while within a given country people with higher incomes were more likely to report being happy, this would not hold at a national level, creating an apparent paradox. He reported data apparently showing that reported happiness was not significantly associated with per capita GDP, among developed nations. Examining trends within nations, he suggested that the increase in income in the United States between 1946 and 1970 contrasted with flat levels of reported happiness, and declines between 1960 and 1970. These claimed differences between nation-level and person-level results fostered an ongoing body of research and debate.
Recent research has utilised several measures of happiness, including biological measures, showing similar patterns of results. This goes some way to answering the problems of self-rated happiness.[quantify] The claim was taken up by Andrew Oswald of the University of Warwick in 1997, driving media interest in the topic.
In 2003, Ruut Veenhoven and Michael Hagerty published an analysis based on various sources of data, and concluded that there was no paradox, and countries did indeed get happier with increasing income. In his reply in 2005 Easterlin maintained his position, suggesting that his critics were using inadequate data.
In 2008, economists Betsey Stevenson and Justin Wolfers, both of the University of Pennsylvania, published a reassessment of the Easterlin paradox using new time-series data. They concluded like Veenhoven et al. that, contrary to Easterlin's claim, increases in absolute income were linked to increased self-reported happiness, for both individual people and whole countries. They found a statistical relationship between happiness and the logarithm of absolute income, suggesting that happiness increased more slowly than income, but no "satiation point" was ever reached. The study provided evidence that absolute income, in addition to relative income, determined happiness. This is in contrast to an extreme understanding of the hedonic treadmill theory where "keeping up with the Joneses" is the only determinant of behavior.
In 2010, Easterlin published data from a sample of 37 countries reaffirming the paradox which was soon questioned by Wolfers. In a 2012 report prepared for the United Nations, Richard Layard, Andrew Clark and Claudia Senik point out that other variables co-vary with wealth, including social trust, and that these, and not income, may drive much of the association of GDP per capita with well-being.
In 2015, psychologists Thomas Gilovich and Amit Kumar published a review which demonstrated that "experiential purchases (such as vacations, concerts, and meals out) tend to bring more lasting happiness than material purchases." They found this was because "Compared to possessions, experiences are less prone to hedonic adaptation".
