This paper presents a simple general equilibrium model involving trips from residential areas to a central business district, along with modal choice between cars and public transit. Car trips involve fixed costs but have lower variable costs per trip (including convenience costs) then bus trips. Using a calibrated numerical model, we investigate the relative merits of ownership and use taxes. We co...
