My article, “Tear Down These Walls,” based on my blog post of the same name, is now out in The Freeman. One highlight:

Immigration reform would dwarf any other measure economists have considered to help people in poor countries. Take microcredit, the lending of small amounts to small businesses. In his recent book, Borderless Economics, Robert Guest notes Harvard University economist Lant Pritchett’s observation that the average gain from a lifetime of microcredit in Bangladesh, such as that provided by Nobel Peace Prize winner Mohammed Yunus’s Grameen Bank, is about the same as the gain from eight weeks working in the United States. Asks Pritchett, “If I get 3,000 Bangladeshi workers into the US, do I get the Nobel Peace Prize?”
