Alons0 (1964) began the development of land use and urban location theory. He proposed a deterministic equilibriurn rnodel based on a micro-economic model where utility depends on the consumption of a generallsed good, property size an d distance to "the centre, subject to an income restriction. This approach; even though simple but illustrative, is an effort to represent the land constlmption Or demand, and the influence of its location in the concept of near-close activities. It is also a preliminary step to the incorporation of time both as a variable and as a resource.
An important forlnulation emerges fi'om the work of Rosen (1974), who specifies the concept of willingness t O pay for a piece of land of certain characteristic, employing the theory of hedonic prices. At the same time Evans (1973) defines as sources of individual utility the plot size, the time devoted to work, the travel time to work (it is assumed that the workplace is located in the CBD) and the tirne devoted to the rest of the activities. From another viewpoint, and in order to advance in the comprehension of the location choice process, it is interesting to note the work of Morigushi and Yoshida (1986). T!leytreat the case of turners explicitly, although in strict terms they donot pay rent, because they face an alternative cost for their dwelling that eventually could allow them to lease it and change location. Their main conclusions go in the direction of defining that the time employed in the different activities is the principal source of utility. The assignment of these times, is held to time and income restrictions and defines tile indMdual state of equilibrium.
More recently it is worth noting the work of Jara-Diaz el al. (1994), that continuing the developments of Evans (I972) propose a model in which utility originates in the time devoted to activities, which are described in terms of their frequency, mean time and quality. Considering the above, this'investigation advances in the line of work of Jara-Diaz e! al. (1994), procuring to contribute to the development of a general location theory. For this, a general model of household location choice is presented in section 2, including a robt!st theorelical fiamework adaptable to the modeller interests. In section 3 a simplified version, adapting the general model to a stated preference (SP) experiment (the data of which was available, Varela el al., 1997) is presented, Setting the scene for the modelling stage described in the fourth section. Finally, section 5 summarises our main conclusions.
