Lot Price

Readers should know by now I love me some economics, but many of its practitioners in recent years have done their discipline a disservice by inflating its explanatory power to cover all decisions made by all people at all times.  My heart is thus sent a-flutter when simple standard economics can be applied appropriately to a problem and do some good. Take parking:

Yes! We've got  a supply of parking spaces, we've got demand for them, now use prices to match them up! Now, as Felix Salmon notes, there's  no reason the pricing couldn't be more dynamic and variable (which would help on the demand side), and as Matt Yglesias says, cities could leave parking space construction to the purview of private people  (which would help on the supply side). Nonetheless, an improvement over the status quo thanks to good economics.
