Jens Hainmueller works to address the fact that there is very little study or evidence about what policies work when it comes to immigrants.
The confusion of the new immigration policies put into place by President Trump succeed in highlighting the complexity of immigration this day in age. Whats more, Carnegie Fellow Jens Hainmueller argues that there isn't enough information on any immigration policy to even know what works and what doesn't.
"What we need to realize is that effective immigration policy in a globalized world is actually pretty complex. You need to carefully think through the consequences and weigh the evidence. Otherwise there is a very good chance that these actions will backfire and harm millions of people."
