ABSTRACT Construction costs account for the bulk of the price of new houses in most markets, but their study has been relatively neglected. We document that there are economically large differences in construction costs across U.S. housing markets. We also estimate a very elastic supply for physical structure; hence, differences in construction activity across markets do not explain the variation in costs. Supply shifters that collectively do account for differences in building costs include the extent of unionization within the construction sector, local wages, local topography in terms of the presence of high hills and mountains, and the local regulatory environment. 相似文献

Successive attempts to reform planning practice in England have given rise to an impression that planning is “under attack”. Various academic commentaries have performed the valuable service of cataloguing aspects of this reform agenda, often within the context of the analytical framework offered by neoliberalization. In this paper, we seek to chronicle the cumulative effects of the sustained programme of neoliberalization to which urban and environmental planning has been subjected in England over a period spanning approximately the last 15 years. In doing so, we hope to show why planning has been such an intractable issue for all governments that have sought its reform irrespective of the particularities of their political agenda. 相似文献

In the described studies with the aim of optimizing hydrated lime grout composition, the first measure was to reduce the water content of the grout using a highly efficient polycarboxylate ether-based superplasticizer, whereas the second measure was to increase the content of the inert limestone filler with an adequate grain size distribution. In this way, an attempt was made to achieve the best possible volume stability and strength properties of the hydrated lime grout, while continuing to fulfill the other necessary requirements regarding non-structural grouting works which are reported in the literature.
The results of the tests showed that a non-structural grout consisting of 1 volume part of hydrated lime CL 90-S and 3 volume parts of inert limestone filler, with 0.5% of the polycarboxylate ether based superplasticizer, fulfilled most of the established requirements, so that it is thus potentially suitable for re-attachment interventions on architectural surfaces. 相似文献
