A new method has been developed to estimate how much people dislike taking risks. By looking at how people's work habits change with different wages and incomes, researchers can figure out this risk aversion. They found that the shape of a person's happiness from work and leisure is linked to how much they change their work hours when wages or incomes change. By studying how people choose to spend their money when job security is uncertain, researchers can also learn how much people like to mix work and play. Based on many past studies, the average level of risk aversion is estimated to be 1.
