ABSTRACT This paper explores theories of population growth, and implied economic growth, among the major U.S. metro areas and regions. One set of theoretical arguments favor the growth of large cities, while an alternative set of arguments favor the growth of the smaller urban areas. Still another set of arguments combine economic space and urban size in the concept of regional growth centers as the engines of regional growth. Granger causality tests are applied to determine the role of urban size or growth centres as engines of regional growth. The test results indicate no causal relationship exists. 相似文献

ABSTRACTIn the late sixteenth and early seventeenth centuries, Welsh writers including the antiquary Humphrey Llwyd, the bard Gruffudd Hiraethog, and the epigrammatist John Owen began referring to themselves as Cambro-Britons. The term was quickly adopted and popularised by English writers, often in ways that show an imperfect grasp of the intentions behind the hyphenated phrase. Whereas the Welsh had hoped that the English and Scots would adopt similar hyphenated identities, English writers tended to interpret “Cambro-Briton” as an intensified and potentially comical expression of Welshness. Though Welsh writers largely ceased to employ the term after the 1620s, the use and misuse of “Cambro-Briton” in English texts continued unabated throughout the century. 相似文献

This paper examines the causes of the current economic crisis in the industrial region of South Wales. The authors maintain that past as well as current government policies have played a major role in bringing about the crisis by contributing to the vulnerability of communities in South Wales. The authors review the history of the policies which have contributed to the current steel and coal crises. They then provide a brief discussion of current legislative policies designed to combat the crises. Finally, they critique alternative strategies: continued monetarism; a return To Keynesian/‘corporatist’ policies; and the radical restructuring demanded by an ‘Alternative Economic Strategy’ (AES). 相似文献
