Syria Refugees and Economy

I am wondering whether Syria refugees have a positive or negative effect or the economy of the host countries.

This paper must talks (Syrian refugees and economy PROS & COST) from local (USA) to global (other host countries). 

APA style, 7 full pages + references page.

at least 5 resources.  

(( I have uploaded one source, the rubrics for the assignment, the question of the paper)) .
