=== Economic considerations ===
According to John Kennan's (2012) data simulations (collected in multiple countries to simulate the effects of open borders), there would be large economic gains between Mexico and the United States of America through the implementation of open borders.<ref name=":2">{{Cite journal|last=Kennan|first=John|date=2013|title=Open borders|journal=Review of Economic Dynamics |volume=16|issue=2|pages=L1–L13|doi=10.1016/j.red.2012.08.003}}</ref> Liberal economic reasoning advocates for open borders to prevent economic inequality between countries where country A is more efficient than country B due to restrictions on immigration creating production efficiency gaps between the two countries. Labor share data estimates that there would be more economic gains through free migration between countries. These gains are expressed through the economic and labor growth in the country along with economic gain for foreign and resident workers in that country.

Economic simulations show that migration lowers the [[Real wages|real wage]] for both countries receiving and sending immigrants; however, the effect of this decrease is based on the goods and services consumed by an individual. According to Kennan “these gains are associated with a relatively small reduction in the real wage in developed countries, and even this effect disappears as the capital–labor ratio adjusts over time.”<ref name=":2" /> Therefore, the number of workers in both receiving and sending countries would double by the current population of workers.
Although the two are not the same issue, free migration is similar in spirit to the concept of [[free trade]], and both are advocated by [[free market]] economists on the grounds that [[economics]] is not a [[zero-sum game]] and that free markets are, in their opinion, the best way to create a fairer and balanced economic system, thereby increasing the overall economic benefits to all concerned parties.<ref>{{Cite journal|last=Clemens|first=Michael|date=2011|title=Economics and Immigration: Trillion Dollar Bills on the Sidewalk?|url=http://www.aeaweb.org/articles.php?doi=10.1257/jep.25.3.83|journal=Journal of Economic Perspectives|volume=25|issue=3|pages=83–106|doi=10.1257/jep.25.3.83|s2cid=59507836|url-access=subscription}}</ref><ref>[http://news.bbc.co.uk/1/hi/world/3512992.stm#Khadria The movement of people and goods is linked], Binod Khadria, BBC News, April 13, 2004.</ref> Political philosopher Adam James Tebble argues that more open borders aid both the economic and institutional development of poorer migrant sending countries, contrary to proponents of "brain-drain" critiques of migration.<ref>{{Cite journal |last=Tebble |first=A.

Notwithstanding noteworthy differences among these political ideologies, many [[Libertarianism|libertarians]],<ref>{{Cite book|last=Brennan|first=Jason|title=Libertarianism – What Everyone Needs to Know|publisher=Oxford University Press|year=2012|pages=42, 50, 119, 125|quote=Libertarians also support free immigration.

Some [[free market]] economists believe that competition is the essence of a healthy economic system, and that any short-term negative impact on individual economic factors that is caused by free migration is more than justified by the prospects of long-term growth for the economy as a whole.<ref>[http://fff.org/explore-freedom/article/defense-free-migration/ In Defense of Free Migration], Richard M.
