Open borders, in the sense of the abolition of policies restricting migration, would cause billions of people to migrate, and result in almost a doubling of world GDP. Based on a model that stresses human capital as a determinant of the wealth and poverty of nations, but which also has a spatial element and allows total factor productivity to differ across cities, two open borders scenarios are constructed. In the first, "pure market clearing" scenario, world GDP rises 91% as 82% of the world's population migrates, mostly to the West, and the living standards of unskilled workers worldwide rise to 26% of the US level. In the second scenario, with several adjustments made to favor greater realism at the expense of some arbitrariness, world GDP rises 85% as 58% of the world's population migrates, and the living standards of unskilled workers worldwide rise to 31% of the US level.
