The first in-depth investigation of whether youthful happiness leads to greater wealth in later life reveals that, even allowing for other influences, happy adolescents are likely to earn more money as adults. Dr Jan-Emmanuel De Neve (UCL Political Science) and Professor Andrew Oswald (University of Warwick) analysed data from 15,000 adolescents and young adults in the USA, finding that those who report higher ‘positive affect’, which is a technical measure of happiness, or higher ‘life satisfaction’ grow up to earn significantly higher levels of income later in life.
