ABSTRACT This paper develops a general multimarket hedonic model appropriate for a national, interregional study of wages, housing prices, and location-specific amenities. The model encompasses the effects of interregional location, intraurban location, and city size. Typically, hedonic studies focus on a single market such as labor or housing and ignore interactions implicit in a more global compensation mechanism. Examination of the comparative statics of our model indicates that single-market differentials are partial prices and are unreliable measures of amenity values in an interregional context. Unbiased amenity values are estimated for a comprehensive set of amenities using data on housing prices for 34,414 households and wages for 46,004 workers from the 1980 Census of Population and Housing. Statistically significant differences in housing prices and wages are found due to amenities.  相似文献

In the last two decades, many states established rail promotion programs in an effort to limit the contraction of their railroad networks. Now federal funds for rail projects are nearly exhausted, and states must decide whether to expand considerably their levels of internal funding for short line investments. Such a decision requires a careful articulation of policy goals, combined with sound cost-benefit techniques. Research shows, however, that states often fail to evaluate the full range of costs and benefits when considering rail investments. Instead, the economic development benefits of local rail service frequently are overstated, while the potential for rail investments to meet broader transportation planning needs is neglected. This paper evaluates the rationale behind state intervention in the rail industry, discusses the tendency of states to focus on economic development to the exclusion of other benefit categories, and presents summary results from an analysis of an investment project in North Carolina. The paper suggests that state funding for rail projects is more likely to be justified based on intermodal substitution benefits generated by local rail service, rather than the railroads' potential to increase jobs.  相似文献

Critics have been uncertain as to the genre of Catalan writer Jaume Cabré's 2000 book, Viatge d’hivern. The confusion, I argue, is due to the fact that the volume is a short story cycle, a literary form situated midway between the novel and the short story collection. Forrest Ingram differentiates among composed, arranged, and completed cycles, and Cabré's comments in his Epilogue to Viatge d’hivern indicate that the book is an example of the third category. While he composed its fourteen narratives over a period of years, when he revised them for inclusion in a single volume he discovered that various threads, some secret and others more obvious, connected the stories. In this essay I examine ways in which theme, structure, and motifs, as well as recurrent imagery and wording, form a web of associations among the individual units of Viatge d’hivern.  相似文献

This article draws on the perspectives of students and organizers involved in recent iterations of the Model Arctic Council (MAC), an experiential learning simulation designed to expand students’ knowledge and understanding of the Arctic and its governance. While much of the discourse related to simulations such as the MAC emphasizes its pedagogical and networking benefits, this article leverages participant-based ethnography to argue that the MAC also affects multi-track diplomatic outcomes in addition to serving as a site for diplomatic engagement. Applying an interpretive approach driven by the onset of practice-tracing in international relations, we demonstrate that the MAC both produces and constitutes diplomacy. Such a reimagination elevates the diplomacy of non-state actors and exposes false binaries between state diplomacy and non-state diplomacy.  相似文献

Optimal Sampling Design for Variables with Varying Spatial Importance   总被引:1,自引:0,他引:1  
It is often desirable to sample in those locations where uncertainty associated with a variable is highest. However, the importance of knowing the variable's value may vary across space. We are interested in the spatial distribution of Received Signal Strength Indicator (RSSI), a measure of the signal strength from a cell tower received at a particular location. It is crucial to estimate RSSI values accurately in order to evaluate the effectiveness of mayday systems designed for rapid emergency notification following vehicle crashes. RSSI estimation is less important for locations where the probability of a crash is low and where the likelihood of call completion is either close to zero or one. We develop a method for augmenting an initial spatial sample of RSSI values to achieve a high‐precision estimate of the probability of call completion following a crash. We illustrate the approach using data on RSSI and vehicle crashes in Erie County, NY.  相似文献

ABSTRACT Water is a resource that both unites and divides people in the Upper Hunter Valley of New South Wales, where many communities are facing the prospect of large‐scale open‐cut coalmining developments on productive mixed use land, or already live in proximity to mines and power stations. This article analyses conflicts over a proposed coal mine at Bickham in the Upper Hunter Valley, by contrasting the various protagonists' discourses of water scarcity, supply, and connectivity. It examines the ways in which the terms of opposition are narrowed to the arena of state and industry supported science and economic development, marginalising other cultural values and environmental ethics that are integral to opponents' discourses. Opponents have achieved some measure of success through contestation of the uncertain science of hydrological modelling, bolstered by the context of drought and increasing public acceptance of climate change science.  相似文献
