A longitudinal approach to migration behavior makes it possible to identify a sufficient condition for positive associations between rates of in-migration and rates of out-migration in the same regions. The longitudinal approach centers on the intervals of time that individuals spend in a region, and these intervals can be analyzed in terms of probability distributions or the equivalent hazard functions or survivor functions. Differences in the distributions of these intervals between subpopulations whose residence in a region begins with in-migration and subpopulations whose residence begins with other events are sufficient for temporal variations in rates of in-migration to produce variations in out-migration rates in subsequent periods of time. Tests for such differences are performed using data from the National Longitudinal Survey of Youth.  相似文献

Current western aid and development policy aims to promote ‘good governance’ in the third world. Few would deny that competent, open and fair administration is both a worthy aim and a self-evident requirement of development. However, the current orthodoxy clearly illustrates the technicist fallacy, which is implicit in the following quotation from Pope, that the effective administration or ‘management’ of development is essentially a technical or practical matter. This article argues that development is fundamentally a political matter and that it is illusory to conceive of good governance as independent of the forms of politics and type of state which alone can generate, sustain and protect it. For Forms of Government, let fools contest; Whate'er is best administered, is best. (Pope, 1734: Bk 3, lines 303-4).  相似文献

ABSTRACT Land price differentials have long been used as a proxy for the value of environmental improvements in cost/benefit analysis. Both the empirical and theoretical literatures have largely ignored two important facts, however: Taxes financing local improvements are often distortionary, and amenities which influence property values in turn impact the fiscal budget, and hence the tax rate and final economic burden. Put another way, the economic cost of an improvement is endogenous to both the amenity level and the revenue structure. Extending the story in this direction for a system of open or closed spatial cities, the paper finds land rent measures to be a biased measure of the willingness to pay for amenities financed by either head taxes (benefit taxes), property taxes (excise taxes), or highway tolls (user fees). These results are used to correct the conventional specification of empirical property value regression models, which traditionally account for neither tax revenue effects nor the excess burden of distortionary taxation.  相似文献

This paper develops a nested family of market interaction models for the general case of spatial or aspatial goods. Market structure effects are identified in the form of intraregional and extraregional competition. The competing destinations and competing central place models are shown to be special cases of the general modeling framework. An empirical example, using survey data collected from Chicago-area Management and Public Relations (SIC 874) firms, illustrates how the family of models may be used to identify market structure.  相似文献

This article addresses Syrian leader Adib al-Shishakli's assault on the Syrian Druze minority in the mid-1950s, the Syrian Druze reaction, and contemporaneous observations and reactions from both the Israeli government and the Israeli Druze community to Shishakli's assault. The events analyzed in this article provide insight into the difficulties and opportunities the Jewish state had in cultivating minority allies in a hostile region, on the one hand, and the dilemmas Middle Eastern minorities had in seeking out the regionally beleaguered Jewish state's support, on the other.  相似文献
