Populations of many countries are expected to decrease rapidly, with a simultaneous increase in the proportion of elderly people. These population dynamics will affect residential location patterns of young and old people because of their different preferences for local (zonal) amenities. Using...

Self-organization of agglomeration patterns for economic models in a two-dimensional economic space is studied from a multi-disciplinary viewpoint of new economic geography, central place theory, and bifurcation theory. Emergence of hexagonal distributions of various sizes in a homogeneous space...

The progress of spatial agglomeration of Krugman's core–periphery model is investigated by comparative static analysis of stable equilibria with respect to transport costs. We set forth theoretically possible agglomeration (bifurcation) patterns for a system of cities spread uniformly on a...

Optimality of urban density regulations differs between a closed city and an open city. We demonstrate, by examining optimal floor area ratio (FAR) regulation, how to control building size to mitigate traffic congestion externality in a monocentric city. Results show that a closed city requires...

Maximum floor area ratio (FAR) regulation is widely imposed in cities to mitigate negative population externalities (e.g. congestion). This paper presents determination of optimal FAR regulation in a two-zone city with a growing population. Results show the following. 1) Maximum FAR regulation...

Previous researches studied how the components of fiscal spending affect the economic growth but did not explicitly enquire into how to adjust the components in order to achieve the highest rate of economic growth starting from the present shares of components. We investigate how to determine...

Using a fully closed monocentric urban setup with unpriced transport congestion, this paper discusses a second best allocation implemented by spatially-variable excise subsidies, or taxes, on housing and the possibility of replacing it by floor area ratio (FAR) regulations. It turns out that the...

This paper numerically evaluates the efficiency of regulations on building size and city size in a congested closed city by comparing welfare gain with that achieved under a first-best toll regime. Results show that whereas the urban growth boundary (UGB) is a poor substitute for the toll regime...
