From an economics perspective both getting a college degree and getting married are beneficial for one’s earning potential. So why do economists promote the college wage premium while downplaying or ignoring the marriage wage premium? As Pascal-Emmanuel Gobry says,
In contemporary societies, there is a strong college wage premium. That is to say, people who go to college make more money on average than people who don’t. While a minority of economists (including Cowen) have questioned why this premium should exist, the majority of economists generally take the existence of this college wage premium to mean that college is good and important, that more people should go to college, and that public policy has some role to play in promoting and subsidizing college attendance. I would bet a goodly sum of money that if you picked at random ten tenured economists from top-20 economics departments, and asked them to list what an 18-year-old should do to increase his chances of getting high wages, a majority would say “go to college.”
There also exists a marriage wage premium, which is roughly as significant and as consistent as the college wage premium. To say that the marriage wage premium doesn’t get the same amount of attention is an understatement. Economists recoil at the idea of praising marriage and supporting public policies that increase marriage. They are much more likely to dismiss the marriage wage premium as reflecting selection bias (it’s not that marriage makes people earn more money, it’s that people who would have earned more money anyway tend to get married) or intone that “correlation is not causation”–criticisms that apply equally to analyses of the college wage premium. I would bet a goodly sum of money that if you picked at random ten tenured economists from top-20 economics departments, and asked them to list what an 18-year-old should do to increase his chances of getting high wages, none of them would say “get married and stay married”–even though the data on the marriage wage premium supports this conclusion to the same extent as it does going to college.
Gobry posits that the reason is bias: economists have an education bias because to become an economist requires numerous years of higher education and they have a liberal-cosmopolitan bias against government encouraging people to make intimate choices.
