This month, citizens and planning officials in Cape Cod, Mass., will get a chance to do what almost no one else in the U.S. is allowed to do when deciding whether to approve or reject a big-box retail development: weigh the likely impacts on the region’s economy.

Thousands of proposals to build big-box stores and shopping centers will be submitted to cities and towns this year. (Walmart alone is pushing to open 220 new stores by January.) In almost every case, local planning policies will limit any review of these projects to conventional zoning issues, like how much traffic the store will generate and whether the site has sufficient landscaping.
