A primary motivation of telework policy is to reduce energy consumption and greenhouse gas emissions. Using a numerical simulation of the standard urban model, we show telework causes sprawl, calling into question the idea that telework decreases energy consumption. Overall effects depend on...

High-occupancy vehicle (HOV) lanes have been promoted to encourage carpools, reduce traffic congestion, and improve air quality. At the partial equilibrium level, commuting with three workers per automobile clearly reduces highway congestion, lowers carbon emissions, and saves energy compared to...
