Location models (Hotelling's linear city)
A location model is a theoretical framework that helps predict the optimal location of a firm in a competitive market. The model assumes that firms are located in a linear city, which is a geographical area where the distance from the firm to all other firms is constant.
According to Hotelling's linear city model, the optimal location of a firm is the point that minimizes the firm's total cost of production. Total cost is the sum of two components: fixed costs, which are independent of the location of the firm, and variable costs, which are dependent on the location.
Fixed costs are costs that remain unchanged regardless of the firm's location, such as land rent, building costs, and marketing expenses.
Variable costs are costs that vary depending on the firm's location, such as transportation costs, labor costs, and raw materials costs.
The model assumes that firms are homogeneous, meaning that they produce identical products at a constant price. This allows the model to focus on the location decision, rather than the production decision.
The model also assumes that firms are perfect competitors, meaning that they produce a good that is perfectly differentiated from other firms. This allows the model to focus on the location decision, rather than the price-setting decision.
The linear city model is a useful tool for understanding the location decisions of firms in competitive markets. It can be used to analyze the effects of changes in market parameters, such as transportation costs or consumer preferences
