As Congress prepares to tackle immigration reform, a new study from the Cato Institute estimates that the difference in the impact on U.S. households between the most and least restrictive policies would be about a quarter of a trillion dollars. Using a model of the U.S. economy developed for the Department of Homeland Security and other U.S. agencies, economists Peter Dixon and Maureen Rimmer conclude that increased restriction of illegal immigration would cost U.S. households $80 billion a year, while legalization through a temporary visa program would raise incomes by $180 billion. Professor Dixon will explain the findings and answer questions about the methodology of the study, and Cato scholar Daniel Griswold will share the results of his new study on immigration and the underclass.
