ABSTRACT. This study develops a computable general equilibrium (CGE) model of California to examine the impact of recent defense cuts on the state's economy. The study demonstrates use of a CGE model to examine the sensitivity of regional economy models to assumptions about factor migration. Model variants include input-output and closed economy models as limiting cases. The results show that the California economy is sensitive to defense cuts. The multiplier relating the impact of defense cuts to state product ranges from one to almost five, depending on the degree of interstate factor mobility.  相似文献

ABSTRACT As the housing stock in a city is duplicated, developers must devote greater amounts of resources to the provision of infrastructure. If the production of infrastructure is characterized by decreasing returns to scale, this will cause the price of developable land to increase. The conditions under which an upward-sloping supply curve for housing will result are discussed. Using cross-sectional data for U.S. cities from 1973 to 1982, it is shown that land prices fail to increase with the quantity of construction and that the price elasticity of the supply of housing is infinite.  相似文献

The information which can be extracted from studying craft and production in past societies is by no means limited to technology and exchange. Analysing the chaîne opératoire of iron production in medieval society provides a new perspective and knowledge of its role for urban development. Seen as a complex network of economic, social and material relations, craft and production are embedded in society and have the power to influence it. This article presents and discusses the remains of blacksmithing found at the site of Rådhuspladsen ('City Hall Square') in Copenhagen. The analysis focuses on the scale, types and organisation of the ironworking, as well as identifying the people who may have been involved, including their social and geographical networks. This study aims to better understand the role of iron production for the development of medieval Copenhagen and in general, its role in medieval Danish towns.  相似文献

This article argues that the academic representation of Islamic history as a single timeline, which was established in the nineteenth century and continues to predominate to the present, is a primary issue restricting fruitful readings of Islamic historical materials. Utilizing insights in thinking about history that favor multiple temporalities, I suggest that scholars in Islamic studies can expand the possibilities of their work by paying attention to the diversity of ways in which time is conceptualized within original materials. As illustrations for the rethinking I advocate, I provide readings of the structures and literary affects of three Persian works in different genres, produced circa 1490–1540 ce . I suggest that a foundational reorientation in the field of Islamic historiography has the potential to help us break out of binds identified in the critique of orientalism provided by Edward Said and others and would lead to better ways to approach developments in Muslim societies.  相似文献

A multidisciplinary programme of research on Islamic pottery has been focused on questions of the dating, provenance and technology of Islamic pottery. One particular question has been the development of stonepaste, a material made primarily of crushed quartz with added frit-glass and clay. The combination of the different approaches of this study has revealed early foundations for the technology in ninth-century AD Iraq, apparently originating in the clay ceramic rather than the ‘Egyptian faience’ tradition. Subsequent and final practice developed in tenth- and eleventh-century AD Egypt. This technology becomes the primary body for all fine Islamic ceramics.  相似文献
