What is "wage premium"? As in:
"As the next graph indicates, young men and women who hail from intact, married homes are much more likely to graduate from college. More precisely, young adults are at least 44 percent more likely to have graduated from college if they were raised by their married parents. This is important because a college degree is associated with better work opportunities, lower odds of unemployment, and a substantial wage premium."
The idea here is that those with college degrees earn more (a "premium") than those without.
