Abstract . Policy and planning have now become the field of a new profession—actually a series of professions—in and out of academic life as each of the specialized social and behavioral sciences is applied to the problems of society by some of its professional practitioners. Specialism, however, tends to make of problems in real life constructs that fit within the borders of one's specialty, constructs which have little relation to reality. To transcend specialism's limitations without prejudice to specialization, interdisciplinary training is proposed and worked out for a single area, social policy and social planning.  相似文献

This paper sets forth a model of knowledge-based regional development conceived as a set of multi-linear dynamics, based on alternative technological paradigms. Utilizing longitudinal data from a Swedish region, and international comparisons, four stages of development are identified: Inception, Implementation, Consolidation and Renewal. Innovation policy is created 'bottom-up' as an outcome of 'collective entrepreneurship' through collaboration among business, government and academic actors – the 'triple helix'. The key event is the creation of an entrepreneurial university, whether from an existing academic base or a new foundation, which takes initiatives together with government and industry to create a support structure for firm formation and regional growth. The result of these initiatives is a self-sustaining dynamic in which the role of academia and government appears to recede as industrial actors come to the fore and a lineage of firms is created. Nevertheless, as one technological paradigm is exhausted and another one is needed as the base for new economic activity, the role of academia and government comes to the fore again in creating the conditions for the next wave of innovation.  相似文献

Loss firms are an economically significant and growing segment of the population of publicly traded corporations. Relatively little is known about the tax positions of loss firms because the firms are typically dropped from tax avoidance studies. We develop a new measure of corporate cash tax avoidance that is meaningful for all observations and reflects the extent to which a firm is tax-favored. We examine the extent to which inferences about corporate tax avoidance over the past twenty-seven years change when we examine the full population of firms, as opposed to a profitable and/or taxable subsample. In contrast to prior research findings, our results suggest that on average firms are tax-disfavored, by which we mean cash taxes paid exceed the product of the firm’s pre-tax book income and the statutory tax rate. In addition, many industries that appear to be tax-favored in profitable subsamples are tax-disfavored when the entire population is examined. We also find that the extent to which firms are tax-disfavored is increasing over time, and that domestic firms are more tax-disfavored than multinationals.  相似文献

In this paper, I present a monopoly screening model in which a firm holds private information on fixed abatement costs. Because of the nature of the optimal contracts, bunching is never optimal even with ‘n’ distinct types. A characterization of full and limited information solutions is offered and it is shown that the design standards alone determine the value of an information rent. The variable charge is completely free of any marginal information costs. This allows the variable charge to track marginal damages and thereby ensures that marginal social costs are covered. A fixed charge implements the optimal solution.  相似文献

We provide the simple example of a refinancing game with incomplete information, where the lack of transparency is both necessary and sufficient for the propagation of local financial distress across disjoint financial networks. JEL Classification Number: F4.

This article investigates the impact of campus bans on alcohol use and the price of alcohol on college students'drinking intensity. The impact of a campus ban on drinking appears to depend on the ability of students to substitute off-campus access to alcohol for on-campus access. Where few off-campus alternatives exist, campus bans reduce the odds that a student becomes a heavy drinker but have no impact on the odds of transitioning from abstainer to drinker. Where off-campus alternatives are more plentiful, campus bans are less effective. Increasing the price of alcohol appears to be equally effective at reducing the likelihood of drinking and heavy drinking. (JEL)  相似文献

中国刚刚取得一项举世瞩目的具有里程碑意义的成就:它已建成世界上最快的超级计算机——天河-1A号。该计算机比设在美国田纳西州橡树岭国家实验室的卫冕冠军快40%。这不是一个孤立的事件。多年来,其他能够反映中国科技能力在不断上升的常见指标,一直在不断涌现,比如,在世界领先的化学和物理学杂志上,来自中国的论文所占的比例在不断增加。  相似文献
