The labor force 30 years from now will look very different as working-age populations in advanced economies start to shrink. While some today worry they’ll lose their jobs to robots, economists like Google’s Hal Varian, wonder if technology will boost productivity enough to compensate for the shifting demographics. Varian, and Harvard’s David Canning, discussed the topic during an IMF World-Bank Spring Meetings seminar earlier this month.
