"State lotteries are popular revenue sources that are unlikely to go away anytime soon," said George Loewenstein, a study co-author and Herbert A. Simon professor of economics and psychology at Carnegie Mellon. "However, it is possible to implement measures that can actually benefit low-income lottery players and lead to fairer outcomes." Loewenstein noted that one such potential method for addressing income inequality, which has shown promise in other countries, is tying lottery tickets to savings accounts.
