In this paper a recursive version of a dynamic road investment problem is developed by extending the Ellet-Walters developmental model of transportation so as to account explicitly for the effects of road investment on the supply and demand of the port hinterland's product. An explicit lagged supply function that depends upon commodity price and road penetration is related to a given linear demand function, assuming annual market clearance. A recursive formulation of a cobweb-like dynamic market is thus obtained. Secondly, we derive the optimal road-penetration policy of a road-planning authority faced with a given cost function and with this form of market dynamics. The road-building policy is constrained both by long-run goals and by short-run market fluctuations so that there are no short-run disbenefits from development. We show that these constraints hold for the general case of downward-sloping demand functions and price and of road-sensitive supplies. The results are then extended to cases where farmers have differing views of future transport availability, indicating the importance of people's perception of development. The paper ends by considering the conditions under which development does not take place. The results imply that an appropriate range of technological change occurs, and that it is related to the existing level of development and the inherent stability of the market.
