The Becker-Posner blog is pretty cool. I like the one labeled “Government stake in private companies: a bad idea.
Governmental ownership of shares, with or without voting rights, opens up possibilities for much greater mischief than controlling executive salaries. For example, a bank or other company may want to reduce its employment in order to regain greater profitability. The government owners of these shares will be under pressure from congressman and senators who represent districts where employment would be affected to try to rescind or modify these cuts.
