introduction • Where firms locate determine future land use, residential location, and transportation decision. • Where in the urban area will a firm locate?
If no competitors • Locate in the center of the area to minimize transportation cost. • If transportation and other cost are substitutable the firm will locate where the MRS of inputs= price ratio

The case of Competitors • Two producers sell the same good • If cost are the same, and prices are f.o.b. (the buyer pays the price at the plant plus shipping charges). • The boundary of the market area between these two sellers will occur where the fright rate are equal.
Market Areas of Two Firms Cost, Price b Distance
Why Firms Concentrate in Space? • If demand is inelastic • And cost are the same every where • Each producer will continue to move toward the other to increase his share of the market until both end up at the center. • The center is not socially optimum location site A X Y B
Factors that Affect Concentration and Dispersion • Price elasticity of demand • Fright rate as a share of total selling price. Uncertainty about one’s competitors Population densities disperse concentrate
Factors that Affect Concentration and Dispersion • Shape of the marginal cost curve (if constant has no effect, if rising concentrate) P2 P3 P1 MC2 Price, Cost MC2 MC1 MC1 R D Quantity
Price of land and Location Decision • The price of land varies inversely with distance from the center of any city. • If a firm desires cheaper land , it will have to give up access to the central city. • As firm move a way from the center , its revenue decline, operating cost increase (because of poorer accessibility). • There should be some price of land the firm is willing to pay at varying distance from the center that will yield the same level of total profit.
Bid-Price Curve • Show how the price of land must vary with distance for a firm to attain the same level of profit • Bid-Price curve have the following properties: • Single value • Downward slope • Lower curve denotes higher profit. • Don’t intersect.

Urban Public Facility Location • Where should the police and fire station be located? • Public facilities can be categorized into two classes: • Point patterns. • network. • There are two opposing forces that affect public facility location decision: • Economic scale • Advantage of disperssion
