On this week's show, Doug speaks to two very interesting guests. In the first half, Professor Terrance Odean returns to discuss his new study on how investment decisions are often driven by emotions such as pride and regret, rather than cold logic.

Doug's second guest, Scott Brusaw, speaks in the second half about his new ideas for solar roadways, which should make road traffic less environmentally harmful and reduce our dependence on oil. Who knows how far reaching the ramifications of this technology will be? Find out by listening to tonight's Goldstein on Gelt show.
