Many countries accept skilled workers to increase domestic human capital.
To complement this policy, some countries are enthusiastic about accepting study migrants. They provide international students with the education and induce students to remain in the host country after education. International students tend to build a large amount of human capital in order to get a skilled job in the host country or in other foreign countries after education.
Japan has been limiting the job that foreigners can take to the skilled one. However, we made a major change in the immigration policy in 2018. In particular, we redefined the 'skilled' job. Newly-defined skilled jobs include jobs that do not require high skill.
Given a situation where international students can be employed for the job that is not necessary high skill after education, do they still keep an incentive to build large human capital?
They do not have to study hard to get a skilled job. Even if they did not study well, they may be able to get a job formally in Japan if they are ok with the unskilled one!
Any ideas? I wonder if you have seen any analytical models to examine this issue (of course, this problem cannot be solved fully without an empirical investigation.)
Thank you.
