From Ryan Avent:
Labour unions: The union menace: I GUESS that one of the benefits of being an old Nobel Prize winner [Gary Becker] is that you can say things like this and not feel the need to provide a shred of supporting evidence:
The real threat to a robust recovery on the labor side has come from employer and entrepreneurial fears that once the economic environment improves, a Democratic Congress and administration will pass pro-union and other pro-worker legislation that will raise the cost of doing business and cut profits. In this way the obvious pro-union-pro-worker bias of the present government has contributed to a slower recovery, especially in labor markets.
And another of the benefits is that supposedly reputable economists [Greg Mankiw] will eat it up, again without providing or demanding the least bit of evidence. Come on, no self-respecting blogger would allege this without deploying, at a minimum, a chart, a table, or a link to a data release! These economists, dragging down the standards of the profession.
