The City of Chicago and the inner suburbs grew much more slowly than the outer suburbs in recent decades. In the central county of the metropolitan area, commercial and industrial property is "classified," in that it is assessed at a higher ratio of market value than residential property. Classification is not used in the surrounding suburban counties. The empirical analysis finds evidence consistent with the notion that property tax classification contributes to differential rates of economic growth. High property tax rates lead to significantly slower growth rates for employment, commercial property, and industrial property.  相似文献

Using data for the 50 U.S. states we relate industry-specific employment growth rates over the period 1976–1989 to the industrial compositions of the states in 1976. We explore the idea that services and manufacturing are inextricably linked and that this interdependence may be beneficial to manufacturing (through knowledge spillovers, for example). Specifically, we test whether the manufacturing sector grew faster in service-based economies. Our evidence does not support the idea of cross-fertilization from services to manufacturing.  相似文献

Reproducible research becomes even more imperative as we build the evidence base on SARS-CoV-2 epidemiology, diagnosis, prevention, and treatment. In his study, Paez assessed the reproducibility of COVID-19 research during the pandemic, using a case study of population density. He found that most articles that assess the relationship of population density and COVID-19 outcomes do not publicly share data and code, except for a few, including our paper, which he stated “illustrates the importance of good reproducibility practices”. Paez recreated our analysis using our code and data from the perspective of spatial analysis, and his new model came to a different conclusion. The disparity between our and Paez’s findings, as well as other existing literature on the topic, give greater impetus to the need for further research. As there has been near exponential growth of COVID-19 research across a wide range of scientific disciplines, reproducible science is a vital component to produce reliable, rigorous, and robust evidence on COVID-19, which will be essential to inform clinical practice and policy in order to effectively eliminate the pandemic.  相似文献

Large wild areas are important for both nature conservation and nature-based recreation. Information on the reciprocal relationships between recreators and the environments in which they recreate can help both conservation and recreation management. We considered motivations, perceptions, environmental concerns, and social concerns among flyfishers who recreate within the Tasmanian Wilderness World Heritage Area on the Central Plateau of Tasmania, Australia. Using semi-structured interviews with 27 participants, we established that they were motivated by a love of nature, desire for experience, escapism, connection, and challenge. On the basis of motivations and attitudes, we discriminated four groups of flyfishers: “social” (those who fish with friends), “trophy” (lone fishers who are goal-oriented), “outdoor enthusiast” (those who enjoy the outdoor experience, fishing optional), and “hunter-gatherer” (those prepared to travel long distances for catch). Nonetheless, all groups perceived environmental and social problems related to fishing and visitation behaviours, from littering to climate change. Fishers perceived environmental problems included identifying exotic weeds and pests but did not specifically include trout as a pest, despite their exotic status and adverse effects on native ecosystems. However, flyfishers were aware of most of their impacts and were willing to help mitigate them. Such insight is significant for geographers and those in associated disciplines and professions seeking to manage wild protected areas.  相似文献
