Just like the Big Dig

The Democratic Convention is poised to suck Boston dry. Here’s Jeff Jacoby in “What the convention is worth”:

There's just one thing wrong with this lucrative convention dividend. It's pie in the sky. According to an analysis released this week by the Beacon Hill Institute at Suffolk University, the convention's net impact on Boston's economy won't be a gain of $150 million but a loss of $12.8 million. Why the drastic difference? Because unlike the cheerleaders who keep chanting "$150 million! $150 million!" the economists at the Beacon Hill Institute live in the real world.

When they close down I-93 for the convention, you’re really going to need a misery index.
