Population Density and Infrastructure Development

Review of Development Economics, 1997
A model is proposed with the following features: (1) there is a publicly accessible transport technology, which is more advanced when there is more specialized labor in it; (2) a high population density facilitates the development of the transport technology; (3) an improved transport technology facilitates a finer division of labor, which in turn ...

ALTERNATIVE EXPLANATIONS OF THE DEPENDENCE OF THE DENSITY OF CENTERS ON THE DENSITY OF POPULATION

Journal of Regional Science, 1993
ABSTRACT. The paper is devoted to modeling the relationship between the density of service centers and the density of population (or on the density of demand). Several models lead to an exponential function with the exponent equal to ⅔. For a number of real systems of centers, the power is considerably different from ⅔ (more often it is nearer to 1 ...
