In the last few days I've received a couple of emails from FedEx with the message below. No doubt other carriers have been sending similar alerts. I don't know, of course, but I have a strong hunch that none of the costs associated with this message (businesses unable to receive their deliveries, carriers having to make contingency plans and add extra staff to catch up after the "festivities", customers having to work around shipping restrictions and delays, etc.) have been accounted for in NFL's economic analysis. After a great storm comes through, there are plenty of estimates of the economic damage it causes. Of course the Super Bowl has benefits that a storm lacks, but I have to wonder if the negative externalities are properly accounted for, or if they just tally the benefits. FedEx message follows...
