Formulate a research question that refers to a return dimension of education that we did not cover in the seminar. The essay has to cite additional literature (at least three references) that is not provided for any of the seminar sessions.

Seminar description
Education is strongly related to benefits on the labour market and in other life domains.
However, returns to education differ markedly between national contexts as well as within
societies (e.g., by gender or social origin). The seminar addresses questions such as: Why is
education rewarded on the labour market? Which institutional set ups are associates with
higher/lower returns to education? Are returns to education, for instance lower for women
and individuals from lower social classes? To that end, we will discuss different sociological
and economic theories on the link between education and labour market placement as well
as empirical studies covering both between- and within-country variation in returns to
education in European and North-American countries. While the focus of the seminar lies on
returns to education on the labour market, we will also touch on further return dimensions
(such as health or civic engagement).
