Today we’re talking about the trade deficit at the request of some of our curious listeners. Since the mid-’70s, the U.S. has persistently been importing more goods than it exports. Is that such a bad thing? We’ll hear from Eswar Prasad, professor of trade policy at Cornell University and a senior fellow at the Brookings Institution, about why the U.S. has a trade deficit, whether it’s a good or bad thing, and why a country’s overall trade deficit matters more than deficits with specific countries.

Then, we’ll get into how online political donations are fueling election campaigns this year. Plus, the malleable idea of “old age” and the wonders of happy sheep in a solar field.
