Technological innovation like automation using robots to produce goods and provide services creates tremendous opportunities for businesses. But as the cost of producing robots goes down, is this technology widening the income gap? Economist Arnaud Costinot has been studying technological change and its impact on inequality, and in this podcast, he discusses how a robot tax might help better distribute the benefits of artificial intelligence, or AI technologies. Arnaud Costinot is a Professor of Economics at MIT, and coauthor of Robots, Trade, and Luddism: A Sufficient Statistic Approach to Optimal Technology Regulation. Costinot was invited to present his research at the IMF.
