Finally, here's a very thought-provoking opinion piece from yesterday's edition of The Boston Globe (***UPDATE*** HT to Greg Mankiw.) on how incentives set up to promote one policy can have a negative effect on another, creating negative externalities that have to be accounted for in the process.
Unintended consequences are a result of any decision because we can't foresee everything. That doesn't mean we shouldn't do a good job in trying to find as many as we can.
I welcome any comments. Have a good weekend.
