Are workers being left behind when the economy grows? Is technology making the human workforce obsolete? James Bessen, author of Learning by Doing, talks with EconTalk host Russ Roberts about the role of learning on the job in the past and in the present. Bessen argues that during times of technological innovation, it often takes years before workers see higher wages from productivity increases. Besson stresses the importance of the standardization of education on the job as workers adapt to new technology.
