What's the Difference Between Joblessness and Unemployment?

Why are fewer men working over the last few decades? Is a universal basic income a good policy for coping with the loss of employment? Economist Edward Glaeser of Harvard University talks with EconTalk host Russ Roberts about what Glaeser calls the war on work--the policy changes that have reduced employment among prime-aged men. Glaeser does not see the universal basic income as a viable solution to the decrease in work especially if technology ends up reducing employment opportunities more dramatically in the future. The conversation also includes a discussion of the role of cities and the reduction in geographic mobility in the United States.
