If you want to know whether money relates to happiness, you might first decide what makes you happy. A Gallup World Poll of 136,000 people in 132 countries from 2005-2006 focused on 2 variables: “life satisfaction” and “enjoyment of life.” Those people who use how much money they have earned as a “scoreboard,” profess to greater life satisfaction because of higher earnings. By contrast, happiness on the “enjoyment of life” scale, which included laughter, friends, and meaningful family connections did not relate to money.
This Gallup Poll is one of many happiness studies we have posted during the past several years. In one previous post, high income people experienced more happiness than low income individuals. We can, though, qualify the high income earners’ happiness with a study that concluded income increases had no impact on happiness. Qualifying it further, we also found a study that contradicts the first one. Then, yet another study asserts that lower quintile earners are happy when upward mobility is feasible. Also, however, a different study demonstrated that happiness comes from earning more than your “neighbor”. Consequently, people preferred lower earnings over higher earnings when the lower number exceeded an associate’s income. Finally, researchers concluded that overworked women, more recently, have become less happy than men.
The Economic Lesson
Thinking economically typically requires looking at the margin. The margin is that imaginary line where we find something extra. For example, marginal revenue is extra money that a business receives for each additional sale. When a business sells a computer, the price of the computer becomes its marginal revenue. For happiness studies, we are at the margin, asking if extra money (at the margin) means extra happiness (at the margin).
