교통서비스의 공급과 헨리 조지의 정리

A version of Henry George Theorem states that when a city is optimally sized, the differential land rent just covers the cost of pure public goods. We reexaimine the theorem in the general equilibrium spatial model with transport facilities. The city is open to population movement. People can commute either by car on congested roads or by mass transit free of congestion. The mass transit costs a fixed sum of monies for its provision. In this fiscal arrangement, the toll revenues exactly cover the cost of roads, and the differential land rents is just sufficient for the fixed cost of mass transit.
