Learning Isn’t Earning
This chapter offers a systematic review of the evidence used to support the key claims of orthodox theory. These include the body of literature showing that investment in education and skills has become more valuable over time as technologically advanced economies come to depend on the brainpower of the workforce. To support this view, orthodox theorists typically compare average rates of return between college and non-college students. There are a number of propositions that can be tested to determine if “learning equals earning.” First, wages reflect human capital investments in education. Second, the value of human capital increases over time. Third, learning equals earnings in all countries. Fourth, reward in the labor market is biased toward the most highly educated workers who will attract higher wages.
