This is the first paper to identify the correlates of workplace managers' perceptions of the health and safety risks faced by workers and the degree to which workers have control over those risks. The risks that workers face and the control they have over those risks are weakly negatively correlated. Managerial risk ratings are positively associated with both injury and illness rates, but not with absence rates. The control rating is also positively associated with injury and illness rates, but it is negatively correlated with absence rates. Workers are more likely to be exposed to health and safety risks when their workplace is performing poorly and where it has been adversely affected by the recession. Union density is positively associated with risks but is not associated with workers' control over risks. Having on‐site worker representatives dealing with health and safety is linked to lower risks than direct consultation between management and employees over health and safety. However, there is no evidence that particular types of health and safety arrangement are related to workers' control over health and safety risks. 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

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

This article examines unconventional entrepreneurship (accidental or end‐user entrepreneurs) to determine whether the decision‐making phase of the entrepreneurial process is collective. The analysis identified a virtuous circle that links knowledge, innovation, judgment, and decision making to collective interactions built on passion, experience, and sharing. To study food bloggers as unconventional user entrepreneurs, data were collected and analyzed using netnographic analysis. A supplementary online survey of food bloggers and their followers was also performed. Three groups of food bloggers are identified: amusing, functional, and fervent. Only fervent food bloggers, thanks to the virtuous circle built on passion, experience, and sharing as enablers, can be considered accidental or end‐user entrepreneurs. 相似文献

ESTIMATING THE EFFECTS OF BROWNFIELDS AND BROWNFIELD REMEDIATION ON PROPERTY VALUES IN A NEW SOUTH CITY 下载免费PDF全文

Using data from Charlotte, NC, a New South city without a legacy of heavily contaminated properties, we find the distance from unremediated brownfields—typically former industrial properties believed to have modest contamination—to have no effect on residential sales values, but proposed cleanup and actual remediation have positive, substantial, and significant effects especially within 0.5 miles of the brownfield. Our results are consistent whether we examine all property values within a given distance, such as 0.5 miles, or examine discrete distances, such as 0.3–0.5 miles. An estimate of the benefits is on the order of $4 million. (JEL Q51, Q24, Q28, R52) 相似文献

This study investigates the determinants of trading volume in the futures markets and focuses on underlying market characteristics
as an explanation for futures trading volume. Four major futures contracts traded on the Sydney Futures Exchange are investigated:
the stock price index (SPI); the 90-day bank accepted bill (BAB); the 3-year bond; and the 10-year bond. An important outcome
of this study is an identification of the fundamental drivers of trading volume in the futures markets, which have largely
gone undocumented in prior research. We find evidence that futures trading volume is related to underlying market characteristics:
the size of the Australian superannuation fund investments in equities (for the SPI), short term treasury notes (for the BAB),
non-government bonds on issue (for the 3-year contract) and government bonds on issue (for the 10-year contract). 相似文献

The implementation of structural adjustment programs (SAPs) has often been undermined by opposition from politically powerful groups who are favored by existing policies. To assess the political sustainability of SAPs this paper uses social accounting matrices for three African countries to model the income effects of stylized SAPs on different socioeconomic groups. The analysis reveals wide variation in the likelihood for typical SAPs to be acceptable to political elites while generating growth in the rest of the economy. The presence of a rural elite or strong farm-nonfarm linkages can enhance the political sustainability of SAPs. 相似文献
