Tyler links to this paper which asks the question “Do Minimum Parking Requirements Force Developers to Provide More Parking than Privately Optimal?” and answers in the affirmative.

I would think that is exactly the purpose of minimum parking requirements, especially in suburbs.  Take as given that residents will resist the installation of parking meters on their streets or other parking restrictions.  Then parking spaces in strip malls have positive externalities for homeowners because they reduce spillover parking in the neighborhoods.  The privately optimal number of parking spaces is therefore too low and mandatory minimums are aimed at correcting that.  The question we are interested in is whether mandatory minimums increase parking space beyond what is socially optimal.
