George J. Borjas, professor of economics and history at Harvard University and author of the recently published Mexican Immigration to the United States, recently started a blog at http://borjas.typepad.com/the_borjas_blog/. With posts on everything from “rockonomics” to the political economy of immigration, Borjas’s blog should be a first stop for anyone looking for insight into some of the nation’s hottest issues, and especially immigration reform in the United States.
