Policy tangle

This is Joseph

One thing that I always find challenging is how to interpret different participation rates in education.  For example, this mini-post by Tyler Cowen suggests that Swedish men are under-represented in college level education.  The original OECD articles notes:

In contrast, only 31% of the bachelor’s degrees awarded in science and engineering went to women.

But this is the same percentage of men who go to university at all in Sweden. 

So what is the threshold to consider policy interventions?  Because if we see the low level of participation in science and engineering by women to require efforts to encourage women to enter these fields, then shouldn't Sweden be intervening to encourage men to complete Bachelor's degrees? 

I admit that just examining the participation rate is divorced from historic context (e.g. gender inequality), and I am sympathetic to these arguments.  But the general issues that under-participation in higher education are likely to bring seem to be the foundation for future issues for current generation of young men and seem to be worth understanding more clearly.
