The authors developed a preliminary, theoretical model of how air quality is affected by different development patters: sprawl, infill, and constant-density growth. Their conclusions depend on the elasticity of emissions: how big a change in emissions is cause by a change in density. If emissions decrease greatly from increased density, then infill is best. If emissions decrease by only a little, then constant density growth is best.
