Two Parables of a Twenty Dollar Bill

There are two important stories about a twenty dollar bill worth telling. The first is best told by Bardach:

Two friends are walking down the street when one stops to pick something up. “What about that—a twenty-dollar bill!” he says. “Couldn’t be,” says the economist. “If it were, somebody would have picked it up already.”

Source: Eugene Bardach, A Practical Guide for Policy Analysis: The Eightfold Path to More Effective Problem Solving, 2nd ed. (Washington: CQ Press, 2005), p. 53.

This is a common story in the economic world and it simply means that if there is an advantage to be had, someone already has it. But it is only half the story.

When I was an undergraduate, about ten of us were walking from the dinning hall to the dorm, I at the back of the group. I saw on the ground ahead of us a twenty-dollar bill. I watched as each of my friends stepped over it and picked it up when my turn came. Then I said, “Hey, everybody! Mr. Jackson does not like being stepped on!”

The lesson is sometimes there are twenty-dollar bills on the ground. It just happens nobody has noticed them yet.

The MTA and Underprovision of Services

As everyone who reads my Twitter knows, I ride the Maryland Transit Administration’s 995 page back and forth from Columbia to DC four days a week.  This morning, the bus left Brokenland Park and Ride at capacity…and four people waiting for the next bus.  This is pretty good since over the past two weeks, we’ve left behind between eight and 21!  And this is a week with many on vacation.  Of course, the MTA does not know this because turnaways are not recorded.

Back in January, the MTA cut service between Howard County and DC and Howard County and Baltimore, despite rising ridership over the past several years.

The sad fact is that many of these people who got out of their cars to enjoy a simpler ride into work are going to get right back in their cars, increasing both pollution and net commute time because MTA fails to provide the service advertised.  Combined with chronic lateness on the return trip, MTA has essentially abandoned their role in Maryland’s smart growth plans.
