Understanding Isodapanes in Space-Economy

The question asks about the author who first introduced the concept of 'Isodapanes' within the field of space-economy, specifically in the context of industrial location theory.

To answer this, we need to understand what Isodapanes are and which prominent economic geographer utilized this concept in their work.

What are Isodapanes?

Isodapanes are lines drawn on a map connecting points that have equal total transportation costs for a specific product or industry. These costs typically include both the cost of transporting raw materials to a production site and the cost of transporting the finished product from the site to the market.

The concept is a tool used in location analysis to identify the area where transportation costs are minimized.

Alfred Weber and His Location Theory

The concept of Isodapanes is most famously associated with Alfred Weber (1868-1958), a German economist and sociologist. Weber developed the "Least Cost Theory" of industrial location, published in 1909 (Theory of the Location of Industries).

Weber's model aimed to find the optimal location for an industry by minimizing production costs, focusing primarily on three factors:

• Transportation costs (most significant factor)
• Labor costs
• Agglomeration (benefits from spatial proximity to other firms)

In his model, Weber used Isodapanes to illustrate how transportation costs vary spatially around the locations of raw materials and the market. By mapping Isodapanes, one could identify areas with the lowest total transportation costs. When labor costs and agglomeration factors were considered, these Isodapanes helped in finding the least-cost location for the industry.

Analyzing the Options

• E. Hoover: Edgar Malone Hoover was another key figure in location theory (known for his work on location of economic activity), but the concept of Isodapanes is not primarily attributed to him.
• A. Losch: August Lösch was a German economist known for his work on spatial equilibrium and the development of central place theory, focusing more on demand and market areas rather than just cost minimization using Isodapanes.
• T. Plander: This name is not widely recognized as a foundational figure in the classical space-economy or location theory alongside Weber, Losch, and Hoover.
• A. Weber: As discussed, Alfred Weber is credited with introducing and extensively using the concept of Isodapanes as a central tool in his least-cost theory of industrial location.

Conclusion

Based on the history of economic geography and industrial location theory, Alfred Weber is the author who initiated and popularized the concept of Isodapanes as a method to determine the location of minimum transport cost in his model.

Additional Information: Weber's Model Simplified

Weber's model considers two raw materials (M1, M2) and a market (C). The ideal location minimizes the combined cost of transporting M1 to the factory, M2 to the factory, and the finished product from the factory to the market.

Imagine the locations of M1, M2, and C form a triangle. The factory could be located anywhere within or outside this triangle. Isodapanes are drawn around these points, showing how transport costs change as you move away from the raw material sources and the market. The point within the lowest-cost isodapane (or where isodapanes are densest towards the cost minimum) represents the ideal location based purely on transport costs.

Weber further adjusted this location by considering labor costs (drawing isolabor lines or isocotdapanes) and potential benefits from agglomeration.
