Francisco Javier Martinez: Abstract and background reading

Title image  F.Martinez

SHORT ABSTACT: A new science of cities is emerging using the microeconomic model of individuals’ behaviour in a geographical context. Heterogeneous agents -individuals, households and firms- interact between then with social and economic objectives on the time and spatial dimensions. At a meso level such interaction requires time, spatial and prices matching, which means that a large number of interdependent markets takes place in the city. This configures a complex system of economic markets and social networks connected by transport of people and goods and communication systems. At a macro scale, cities a universal pattern described by scale laws, where their inputs and outputs increase non-linearly with the population size. This presentation describes a model of the complex urban system from the micro to the macro levels, with interesting properties such as the convergence of the system to attractors that explains universality of the scale laws. Its fractal structure allows the extension of the model from the single city to a structure of cities and regions. Building a coherent multi-scales model of cities is the foundation rock of an urban science, which in this case is built from the contribution of multiple disciplines.
