Professor Satya Paul , a professor of economics at the University of Western Sydney said, ''Income doesn't have a significant effect on happiness, but I wondered if happy people were more productive than others, and if happy people could affect their income generation through how much they worked. ''
Professor Paul studied 9300 people's self analysis and happiness quotient tracking this data for four years. The insight led him to conclude that the happier ones are more productive and also earned more money. ''We found happy people are more active, more productive and get less upset by the work,'' he said.
Converting it to numbers, Professor Paul said that when other income factors such as age, education and geographic location are the same, Australians who are most satisfied with their life got to earn about $1766.70 a year more than unhappy people.
''Happiness affects hours, happy people tend to work more, and their incomes increase. Also, happy people can like to have more leisure time in their lives, and work less, but can be more productive because of that leisure time.This is a lesson we can take, the more happy people are, the less inequality in incomes we can have in society,'' he said.
