Urban policy transfer between the US and UK has long been of interest to researchers and practitioners. Given the recent wider context of reduced direct funding and the absence of a coherent regeneration policy, this paper considers the introduction of Tax Increment Financing (TIF) to the UK as a method of stimulating spatially targeted economic development initiatives. The paper explores whether TIF could be considered a form of policy transfer, and in doing so uncovers whether the transfer of TIF could – (a) be successful and unsuccessful under certain circumstances; (b) require the actions of certain stakeholders; and (c) be enabled via prescribed frameworks and negotiation. The results are evidenced using qualitative approaches and find that TIF is more of a modified policy ‘idea’ rather than transfer. Further discussion argues that TIF can be successful, if it considers flexible but local elements and has the capacity to balance stakeholders for development brokerage.  相似文献

In hazard models, it is assumed that all heterogeneity is captured by a set of theoretically relevant covariates. In many applications however, there are ample reasons for unobserved heterogeneity due to omitted or unmeasured factors. If there is unmeasured frailty, the hazard will not only be a function of the covariates but also of the unmeasured frailty. This paper discusses the implications of unobserved heterogeneity on parameter estimates with application to the analysis of infant death on subsequent birth timing in Ghana and Kenya using DHS data. Using Lognormal Accelerated Failure Time models with and without frailty, we found that standard models that do not control for unobserved heterogeneity produced biased estimates by overstating the degree of positive dependence and underestimating the degree of negative dependence. The implications of the findings are discussed.  相似文献

今年早些时候,《纽约时报》艺术评论家罗伯塔?史密斯写了篇长文章,指出美国许多美术馆明显偏好后极少主义,是一种"视野极端狭窄"的表现。这篇极富争议性的文章敦促策展人提高思想独立性,跳出观念艺术一统天下的模式看作品。读完文章,我发现她说得很对,西方不少美术馆在决定哪些作品可以进入当代艺术圣殿上的确存在趣味专制。刘小东的作品就很能说明这个问题。我放下报纸开始想,自己是不是应该站出来向我的纽约同事们为刘小东的绘画、思考以及历史意义正名。于是便有了本文。  相似文献

An important current of thinking in the last decade has emphasized the need for a shift from control to commitment as the central objective of management employment policies. This paper is concerned to assess whether there was a significant increase in British employees' commitment to their organizations in the 1990s, using comparative data from two large-scale and nationally representative surveys carried out in 1992 and 1997. It finds that there was no evidence of an increase in commitment over the period. As in the early part of the decade, employees had only a weak level of attachment to their organizations. The analysis examines a number of factors that have been seen as important determinants of such commitment: changes in the level of skill, task discretion, controls over work performance, and forms of employee involvement. While there were changes in some of these factors that encouraged higher commitment, these were largely cancelled out by a notable decline in the discretion that employees were allowed to exercise over their work.  相似文献

In the mid‐1980s, financial economists began building option‐based models to value corporate investments in real assets, laying the foundation for an extensive academic literature in this area. The 1990s saw several books, numerous conferences, and many articles aimed at corporate practitioners, who began to experiment with these techniques. Now, as we approach the end of 2001, the real options approach to valuing real investments has established a solid, albeit limited, foothold in the corporate world. Based on their recent interviews with 39 individuals from 34 companies in seven different industries, the authors of this article attempt to answer the question, “How is real options being practiced, and what impact is it having in the corporate setting?” The article identifies three main corporate uses of real options—as a strategic way of thinking, an analytical valuation tool, and an organization‐wide process for evaluating, monitoring, and managing capital investments. For example, in some companies, real options is used as an input into an M&A process in which rigorous numerical analysis plays only a small role. In such cases, real options contributes as a qualitative way of thinking, with little formality either in terms of analytical rigor or organizational procedure. In other firms, real options is used in a commodity trading environment where options are clearly specified in contracts and simply need to be valued. In this case, real options functions as an analytical tool, though generally only in specialized areas of the firm and not on an organization‐wide basis. In still other companies, real options is used in a technology or R&D context where the firm's success is driven by identifying and managing potential sources of flexibility. In such cases, real options functions as an organization‐wide process with both a broad conceptual and analytical core. The companies that have shown the greatest interest in real options generally operate in industries where large investments with uncertain returns are commonplace, such as oil and gas, and life sciences. Major applications include the evaluation of exploration and production investments in oil and gas firms, generation plant investments in power firms, R&D portfolios in pharmaceutical and biotech firms, and technology investment portfolios in high‐tech firms. While the approaches to implementation are quite varied, there appears to be a common path to the successful adoption of real options. The key steps of the adoption process are: (1) conducting pilot projects; (2) getting buy‐in from senior‐level and rank‐and‐file managers; (3) codifying real options through expert working groups, specialist training, and customization; and (4) institutionalizing and integrating real options firm‐wide. After citing best practices for each of these four steps, the authors close by predicting that a “network” effect and acceptance by Wall Street will serve as catalysts for more widespread corporate use of real options.  相似文献

Sraffa's legacy     
This review essay of Critical Essays on Piero Sraffa's Legacyin economics situates Sraffa's work in relation to the Marshalliantradition and neo-Walrasian general equilibrium theory, andreviews the current state of debate between adherents of thesetraditions on the role of demand, returns to scale, capitaltheory and policy analysis. Other issues considered includethe corn model, Sraffa's critique of Hayek, and the extensionof the capital theory critique to the intertemporal equilibriummodel.  相似文献

This article extends previous literature which examines the determinants of the price impact of block trades on the Australian Stock Exchange. As previous literature suggests that liquidity exhibits intraday patterns, we introduce time of day dummy variables to explore time dependencies in price impact. Following theoretical developments in previous literature, the explanatory power of the bid–ask spread, a lagged cumulative stock return variable and a refined measure of market returns are also examined. The model estimated explains approximately 29 per cent of the variation in price impact. Block trades executed in the first hour of trading experience the greatest price impact, while market conditions, lagged stock returns and bid–ask spreads are positively related to price impact. The bid–ask spread provides most of the explanatory power. This suggests that liquidity is the main driver of price impact.  相似文献
