Containing sprawl is a major preoccupation of many urban planners, who view sprawl as responsible for driving up environmental costs and congestion.  Nevertheless, many economists see benefits to sprawl, allowing households access to larger and cheaper properties. This Round Table examines the costs and benefits of sprawl, shedding light on the linkages between urban form and economic growth, and explored the tradeoffs involved in trying to contain sprawl. Discussions were based on papers prepared by Elizabeth Deakin (UC Berkeley), Matthew Kahn (Tufts University), Gilles Duranton (University of Toronto) and David Banister (University College London).
