Who doesn't need more money? We've given you many ideas to earn extra income, but sometimes there are intangible factors you may or may not have control over that affect your salary. Thankfully, we have scientists hard at work in their labs trying to figure out the answers for us. Here are various results of research studies of the things that impact income:
- Height: An Australian study found that 6-foot men earned $1,000 more than guys who were two inches shorter. "Taller people are perceived to be more intelligent and powerful," says the study.
- Regular exercise: People who work out regularly, according to a study in the Journal of Labor Research, earn nine percent more than their couch potato peers. Perhaps your monthly gym membership is literally paying off.
- Popularity in high school: Being well-liked in high school isn't something we can change right now, but if you were one of the cool kids, you're in luck. A National Bureau of Economic Research study says people who were among the top fifth most popular students in high school, earn a 10 percent premium on salary four decades later compared with the bottom fifth.
- When you marry: College-educated women who marry past their 30s make more income, while men who marry earlier see more financial benefits, according to a study by the National Marriage Project. One reason could be: women who marry earlier tend to have kids earlier as well, which forces them to take a break from their career during a period when they'll see a lot of growth. As for men, perhaps those who marry earlier tend to be more secure and confident than their single friends, leading to higher productivity.
