Unions win one

President Obama has issued an executive order that permits federal agencies to require union labor for work on federal contracts. This is good news for union workers, bad news for non-union workers, and bad news for taxpayers, who will pay more for what the government buys on their behalf. In my judgment, it is bad news from a macroeconomic perspective. As I learned from Professor Larry Summers, one "cause of long-term unemployment is unionization."
