The U.S. is known around the world for its problem with gun violence. The vast majority of murders in the U.S. are committed using guns. But what leads one person to shoot another? The "conventional wisdom" says gun violence is usually the act of calculated criminals or people acting out of desperate economic circumstances. But economist Jens Ludwig believes the conventional wisdom is wrong. Today on the show, he explains why he believes many of us fundamentally misunderstand the problem of gun violence and how behavioral economics reveals some potential solutions. Jens's new book detailing his research into gun violence is called "Unforgiving Places: The Unexpected Origins of American Gun Violence".
