The Brookings Institution, which conducts research in economics, urban policy, governance, foreign policy, and global economy and development, is often considered the most influential think tank in the world. Now readers can access the big ideas Brookings is famous for in digestible video installments on the Institution's YouTube channel. Recent topics have explored everything from girls' global education to race in America to how to bring back manufacturing in the U.S. Most videos are between one and three minutes long, though some films of speeches and panel discussions can go on for an hour or more. One particularly interesting episode features economist David Wessel's analysis of whether federal taxes reduce income inequality in the United States. The answer? Somewhat, but not much.
