Location theory


Location theory has become an integral part of economic geography, regional science, and spatial economics. Location theory addresses questions of what economic activities are located where and why. Location theory or microeconomic theory generally assumes that agents act in their own self-interest. Firms thus choose locations that maximize their profits and individuals choose locations that maximize their utility.

While others should get some credit for earlier work (e.g., Richard Cantillon, Etienne Bonnot de Condillac, David Hume, Sir James D . Steuart, and David Ricardo), it was not until the publication of Johann Heinrich von Thünen's first volume of Der Isolierte Staat in 1826 that location theory can be said to have really gotten underway. Indeed, the prominent regional scientist Walter Isard has called von Thünen "the father of location theorists." In Der Isolierte Staat, von Thünen notes that the costs of transporting goods consumes some of Ricardo's economic rent. He notes that because these transportation costs and, of course, economic rents, vary across goods, different land uses and use intensities will result with increased distance from the marketplace. However, the discussion was criticized since Johann Heinrich von Thünen oversimplified the problem with his assumptions of, for example, isolated states or single cities.

Tord Palander (1935) wrote: Market area division of two competing firms.

A German hegemony of sorts seems to have taken hold in location theory from the time of von Thünen through to Walter Christaller's 1933 book Die Zentralen Orte in Sűddeutschland, which formulated much of what is now understood as central place theory. An especially notable contribution was made by Alfred Weber, who published Über den Standort der Industrien in 1909. Working from a model akin to a physical frame adapted from some ideas by Pierre Varignon (a Varignon frame), Weber applies freight rates of resources and finished goods, along with the finished good's production function, to develop an algorithm that identifies the optimal location for manufacturing plant. He also introduces distortions induced by labor and both agglomerative and deglomerative forces. Weber then discusses groupings of production units, anticipating Lösch's market areas.
