The Value of a Degree
Introduction
Many of our readers are students, and some have come to us wondering whether they should start a university degree or complete one they have already started. One thing to consider in making this decision is what effect getting a degree will have on your lifetime earnings. So in this post we summarise our reading of some of the empirical literature on this question, mostly focused on the UK.
Summary
There appears to be a consensus in the empirical literature that getting a degree provides a large financial return on the costs in increased lifetime earnings (generally better than an investment with a 10% return and maybe closer to 15%).
The most common way of studying the question of economic returns is to use correlations in data containing information on education, earnings and other variables (performing “ordinary least square regression” on it).
The obvious worry with this method is that the same abilities that help earn a higher income might cause people to go to university rather than the other way around. This is called ability bias. The standard view in the literature, however, is that this issue only has as minor effect on estimates of the return to education.
The literature here supports the common sense position that an undergraduate degree is generally a good investment in your career.
