Free parking for all in shopping malls

This is the latest version of this item.

We show why a shopping mall prefers to provide parking for free and embed the parking costs in the prices of the goods. This holds if the mall has monopoly power or prices competitively; if there is parking validation or a trade-off between shopping and parking spaces. It is also the second-best social optimum. Generally, the equilibrium lot size is too small, yielding a rationale for minimum parking requirements. In urban malls, parking fees may be positive because individuals can use the lot without intending to shop, and lots may become too large because of the trade-off between shopping and parking spaces.the trade-off between lot size and shopping space.
