(..) The contemporaneous relevance of von Thünen’s model lies in its adaptation to urban economics, allowing the study of urban and suburban rents and of the location of families and economic activities in the cities. Following a suggestion of Isard (1956), Alonso (1960) generalized the model of von Thünen, explaining the demand for location near commercial centres like shopping malls, employment centres such as skyscraper headquarters, and to stadiums and other leisure centres. The fundamental characteristic of the urban economy reflected in the model is the need for families to go to the centre to work using a radial transportation system.

This structure thus became the typical model of urban economics. Solow (1973) fitted it into the neoclassical model of consumer theory, while Mills (1967) endogenized the dimension of the cities. From this point, the contributions multiplied. A fault in this approach is that it assumes something we want to explain: the existence of an urban central market. (..) [destaque PJ]
