The present paper highlights the importance of house price index methodology and relevance of studying price indices within a metropolitan region. Two approaches based on hedonic approach have been compared. Though the results are inconclusive as to whether explicit time variable hedonic approach is superior to cross section hedonic approach or vice versa but there are evidences that would suggest that cross section approach is better. The results are compared with indices developed by other methodologies like improved repeat sales method and official methodology of SCB. The index obtained by us are very similar to others but the quarterly price increases as calculated by us lags the other two. This paper further tries to explain the intra-metropolitan price variations based on population, employment and tenureship trends. A ripple effect is also noticed where the prices in one zone leads the others.
The shortage of land for solid waste disposal has been a very important problem in many developed countries. To solve this problem, we must decrease the amount of waste. Various kinds of policies as countermeasures have been implemented in such countries. We compare six household waste recycling policies with respect to the social welfare levels in a partial equilibrium framework: the status quo, unit pricing, recycling subsidy, advance disposal and recycling fee, deposit/refund system and producer take-back requimement with unit pricing. In this paper, we obtained the following results. Unit pricing and deposit/refund system and, producer take-back requirement with unit pricing are the first best policies. However, the orders of the social welfare associated with the other policies depend on the constant marginal dinposal cost. This result is important because we can not always implement the first best policies for some reasons. For example, unit pricing can be faced with the political opposition to what is perceived as a new tax, and deposit/refund system may be suffered from its high transaction cost.
The paper addresses one of a traial for evaluation that different planning systems are suitable for sustainable regional development using a simulation game PANGAEA, which facilitates professional planners' training. The concept of “sustainable development” was proclaimed at the Earth Summit, 1992, and has been widely accepted and supported by both developing and developed countries. Although it is easy to see that we need “sustainable development” approaches, we cannot pretend that it is similarly simple and straightforward to realize sustainable development processes. As a professional planning exercise for human resource development, there are four key controlling factors to achieve sustainable regional development in PANGAEA: capacity, distribution, pace, and efficiency. Although main objective of PANGAEA is planner training, it is not ordinary result but it give us a precious hint for the future that different governmental institutions as planning systems would generate better their own public investment plans toward sustainable development by running and stock of some planner training. From the point of view of local optimization in planning function, decentralized planning system might work well for keeping balance with development and environmental preservation less failure One of a result shows decentralization was suit for sustainable development under some conditions.
