Entering foreign workers; effect to economic growth.?

Question

i have a problem with what the measured that would i use, what the methodologist of reaserch, what data i need and waht is the model i should prefer.

Answer 1

It is hard to analyze the impact of foreign workers on economy empirically. There is no data about it. Growth is affected by consumption, investment, government purchases, and net exports. Y= C+ I + G + NX, the basic macroeconomic model.

Answer 2

They keep some sectors going by doing the jobs that  others won't do---Then people wonder why the c**p jobs are outsourced

Answer 3

I would focus on highly skilled workers.  The effect of limiting foreign workers is that economic growth can be stalled, especially if there are not enough qualified US citizens (such as in IT industries).  Also, there can be severe shortages in areas like nursing when foreigners aren't allowed to easily come to work.  

I would look at high-demand skills visas over time, and measure against growth in those sectors (there are other factors, don't forget).  A simple supply-demand model would also suffice--with fewer workers (less supply), higher demand leads to lack of innovation and production.
