The Center for American Progress and the Immigration Policy Center released a new study this morning that finds comprehensive immigration reform would boost the U.S. economy by $189 billion a year by 2019. The bottom‐​line results of the study are remarkably similar to those of a Cato study released last August.


Titled “Raising the Floor for American Workers: the Economic Benefits of Comprehensive Immigration Reform,” the CAP study was authored by Dr. Raul Hinojosa‐​Ojeda of the University of California, Los Angeles.


It finds that legalizing low‐​skilled immigration would boost U.S. gross domestic product by 0.84 percent by raising the productivity of immigrant workers and expanding activity throughout the economy.


Using a different general‐​equilibrium model of the U.S. economy, the earlier Cato study (“Restriction or Legalization? Measuring the Economic Benefits of Immigration Reform,” by Peter Dixon and Maureen Rimmer) found that a robust temporary worker program would boost the incomes of U.S. households by $180 billion a year by 2019.


Both studies also concluded that tighter restrictions and reduced low‐​skilled immigration would impose large costs on native‐​born Americans by shrinking the overall economy and lowering worker productivity.


I’m partial to the Cato study. Its methodology is more comprehensive and more fully explained, but it is worth noting that very different think tanks employing two different models have come to the same result: Legalization of immigration will expand the U.S. economy and incomes, while an “enforcement only” policy of further restrictions will only depress economic activity.


If Congress and President Obama want to create better jobs and stimulate the economy, comprehensive immigration reform should be high on the agenda.
