In my inequality post , I wrote , somewhat speculatively ,

The returns to pedagogy chosen as well as worked difficult for are non necessarily replicated inwards pedagogy subsidized or forced.

Marginal Revolution points to a nice novel paper by Pierre Mouganie making this point. From the abstract:

In 1997 , the French authorities lay into outcome a constabulary that permanently exempted immature French manlike somebody citizens born afterwards January ane , 1979 from mandatory military machine service piece withal requiring those born earlier that cutoff engagement to serve. ... conscription eligibility induces a meaning increment inwards years of pedagogy , which is consistent alongside conscription avoidance behavior. However , this increased pedagogy does non termination inwards either an increment inwards graduation rates , or inwards usage as well as wages. Additional bear witness shows conscription has no straight outcome on net turn a profit , suggesting that the returns to pedagogy induced past times this policy was zero.
