This article addresses the problem of specification uncertainty in modeling spatial economic theories in stochastic form. It is ascertained that the traditional approach to spatial econometric modeling does not adequately deal with the type and extent of specification uncertainty commonly encountered in spatial economic analyses. Two alternative spatial econometric modeling procedures proposed in the literature are reviewed and shown to be suitable for analyzing systematically two sources of specification uncertainty, viz., the level of aggregation and the spatio-temporal dynamic structure in multiregional econometric models. The usefulness of one of these specification procedures is illustrated by the construction of a simple multiregional model for The Netherlands. 相似文献

The advent of the Hawke government may not warrant the title of ‘The Revolution in Australian Politics’, but it has raised questions about organisation and power, and the way in which these are handled in political science. This paper begins by identifying what is considered problematic in the political practices which are seen as distinctive in the Hawke government. It outlines the elements of the paradigm of organisation which underlies much political science, and identifies the way in which these are challenged by ‘corporatist’ or ‘Hawkeish’ forms of political activity. It argues that this paradigm of organisation is under attack on both conceptual and empirical grounds, and outlines an alternative paradigm of organisation and the way in which it applies to government. It concludes with a consideration of the implications of this approach for theorising about the state. 相似文献

The Multiregional Variable Input-Output (MRVIO) model is introduced to measure the development impact of a transportation system. The MRVIO model is a theoretically flexible, computationally simple, and cost-responsive model. Under the MRVIO model, regional input-output coefficients, trade coefficients, and trade flows become cost responsive and easy to compute. The MRVIO model is employed to measure the development impact of the Arkansas waterway during the period of 1974 to 1978. In the study, the U.S. economy is disaggregated into 3 regions and 35 industrial sectors. The MRVIO model estimates the economic conditions of these 3 regions with and without the waterway in terms of industrial output, income, employment, and trade flows. 相似文献
