Abstract

This paper presents a theoretical study regarding occupations of flood prone areas by illegal settlements in urban area of Palangkaraya city, Central Kalimantan province, Indonesia. Such unusual urban land use pattern has been observed in many urbanized cities particularly in developing countries. However, scientific explanations about the urban phenomena were not formulated yet as well as literatures on that topic are quite rare. We developed a partial equilibrium model employing bid rent approach to analyze such unusual urban land use pattern. The model incorporated flood damage rate corresponding to household`s assets introducing variants of bid rent function and bid max lot size function. Differently from other traditional urban economics models, our model depicts a reverse conclusion of land allocation particularly in flood prone areas. In the flood prone areas, the bid rent of representative low income households gets higher than that by the representative high income households hence as a result the flood prone areas are settled by low income households emerging colonies of illegal settlements within city areas.

Abstract

The aim of the present paper is to offer an exploratory contribution to the general debate on sustainable transport, in particular from the perspective of impact assessment of sustainable transport policy. Specifically, starting from data available from different public sources in the United States, two different types of analyses are conducted: (1) comparison of the declared short term results of the most practical policies applied (e.g. ramp metering, HOV lanes, etc.); and (2) an analysis of mobility data to interpret long term effects of policy previously and semi-unconsciously applied. In particular, the latter point has a more innovative character with respect to the former. It is based on the assumption that, specifically in the West Coast of the United States, at a local scale (e.g. states), policies that would be defined as sustainable today, have already been applied in the past.

Abstract:

We have developed a dynamic spatial computable general equilibrium model to investigate the regional economic impacts of an earthquake. In our spatial model, Japan is subdivided into 47 regions. All the regions are connected by transportation networks. Our model is of a decentralized economy with utility-maximizing consumers and value-maximizing firms in a dynamic context. The model embodies both the spatial commodity flows among regions and the dynamics of regional investments. The model is calibrated for the regional economy using a multi-regional input-output table for Japan. We estimate the impacts of a hypothetical earthquake, which is expected to occur in the near future, on the regional economy in a case study of the Tokai region of Japan. The results show the indirect and distributional economic impacts before and after an earthquake. This study suggests that any disaster analysis should evaluate the economic impacts of a disaster based on both ex-ante and ex-post criteria.
