This article is concerned with the economics of excessively large and socially costly suburban expansion and attempts to summarize and organize the main economic arguments associated with sprawl due to single-family residential home construction. We also apply standard welfare economics and price policy instruments to the issue of suburban sprawl in order to suggest ways in which economics can participate in and inform the debate over sprawl. The article uses the Inland Empire, which includes the valley regions of San Bernardino and Riverside Counties in Southern California east of Los Angeles, as a case study.

The development of asset pricing models that rely on instrumental variables together with the increased availability of easily-accessible economic time-series have renewed interest in predicting security returns. Evaluating the significance of these new research findings, however, is no easy task. Because these asset pricing theory tests are not independent, classical methods of assessing goodness-of-fit are inappropriate. This study investigates the distribution of the maximal R 2 when k of m regressors are used to predict security returns. We provide a simple procedure that adjusts critical R 2 values to account for selecting variables by searching among potential regressors.  相似文献

Independent inventors accounted for approximately half of all patents in Britain and Japan by 1930, despite the rise of the corporate economy and the spread of industrial R&D. A mixture of patent renewal and historical citations data reveals that the quality of independent invention was high. Active markets for inventions created incentives for independents, especially in large cities like London and Tokyo, which dominated spatially. Alongside evidence for the US, the findings show that in countries with different patent systems and at varying stages of economic development, a key component of overall inventive activity originated from outside the boundaries of firms.  相似文献

Kingston (1995) discusses the legal complications arising out of the foreign currency loans taken out in the middle eighties. This note discusses a number of points of difference within Kingston's interpretations. The most important example of these is the predictability of the losses arising from the loans. Some potential solutions of the problems identified by Kingston, and in this note, are also canvassed.  相似文献

This study examines whether any regularity exists in the publication pattern among accounting researchers. The empirical results reveal that a strong bibliometric regularity exists in the accounting literature: the number of authors publishing in papers is approximately 1/ n c of those publishing one paper. It is shown that the accounting literature conforms very well to the model with c=1.872 if data are taken from a large collection of journals. When applied to individual journals, the result shows that values of c range from 2.220 to 4.368. The graduates of seven graduate programs are found to account for more than one-third of the most prolific authors, indicating strong institutional dominance in the production of accounting literature.  相似文献
