Quick Summary

The age-earnings profile illustrates how an individual's income typically changes throughout their working life. This concept is closely tied to human-capital theory, which posits that earnings are influenced by an individual's acquired skills and knowledge. Investing in education and training, for example, can lead to higher future earnings, even if it means lower income in the short term due to foregoing immediate employment opportunities. Consequently, individuals with more education often experience a steeper age-earnings profile, earning more over their lifetimes compared to those with less schooling, though total lifetime earnings can be similar under certain conditions.1
