要旨

This paper investigates the optimality condition of transport network development in a closed city with residents’ and absentee land ownerships. We set up an urban land use model in which, taking prices and characteristics of transport network as given, households that are identical in their preferences and endowments maximize utility by choosing residential location, lot size, and travel modes. Social planner then optimizes with respect to the characteristics of transportation network so as to maximize the level of utility in the spatial equilibrium. The key findings of this paper include that under resident landlord case the general optimality condition of the transport network improvement is such that the marginal cost of improvement is equal to the marginal increase in the aggregated differential land rent evaluated at current level of land rent.
