This paper investigates the impact of R&D disclosure and finance variables on the level of R&D expenditures. The question addressed is: what is the impact of changes in disclosure requirements on the relationship between R&D expenditure and the financing of firms? The question is motivated by the possible signalling role that elective disclosure may have had prior to changes in accounting practices to ensure R&D disclosure.  相似文献

We combine natural science modelling and valuation techniques to present economic analyses of a variety of land use change scenarios generated for the UK National Ecosystem Assessment. Specifically, the agricultural, greenhouse gas, recreational and urban greenspace impacts of the envisioned land use changes are valued. Particular attention is given to the incorporation of spatial variation in the natural environment and to addressing issues such as biodiversity impacts where reliable values are not available. Results show that the incorporation of ecosystem services and their values within analyses can substantially change decisions.  相似文献

The Grose River is contained almost entirely within a World Heritage Area. While sewage pollution in the area has been addressed, pollution at damaging levels continues from a disused coal mine, closed in 1997. Despite some surface rehabilitation, no action has occurred to remediate zinc polluted waters emanating from the mine. We examine the historical regulation and management of the Australian Commonwealth and New South Wales governments and highlight gaps in both regulatory systems. We conclude that there is an urgent need to improve regulation of water pollution, mining and management of the environment in highly valued world heritage areas.  相似文献

We show that all-pay auctions dominate first-price sealed-bid auctions when bidders face budget constraints. This ranking is explained by the fact that budget constraints bind less frequently in the all-pay auctions, which leads to more aggressive bidding in that format.  相似文献

This paper explores the issue of a simultaneous reduction in tariffs at different stages of a vertically related market where each stage is oligopolistic. When vertically related markets are characterized as a successive oligopoly, reducing tariffs by an equivalent amount on upstream and downstream imports will have a differential effect on market access and hence profits at each stage as a result of a combination of horizontal and vertical effects. These differential effects have implications for the tariff structure post‐trade reform.  相似文献

A new approach to valuing ecosystem goods and services (EGS) is described which incorporates components of the economic theory of value, the theory of valuation (USappraisal), a multi-model multiple criteria analysis (MCA) of ecosystem attributes, and a Delphi panel of experts to assign weights to the attributes. The total value of ecosystem goods and services in the various tenure categories in the Wet Tropics World Heritage Area (WTWHA) in Australia was found to be in the range AUD$188 to $211 million year−1, or AUD$210 to 236 ha−1 year−1 across tenures, as at 30 June 2002. Application of the weightings assigned by the Delphi panelists and assessment of the ecological integrity of the various tenure categories resulted in values being derived for individual ecosystem services in the World Heritage Area. Biodiversity and refugia were the two attributes ranked most highly at AUD$18.6 to $20.9 million year−1 and AUD$16.6 to $18.2 million year−1, respectively.  相似文献

As industries mature, experience is accumulated, productivity increases, trade performance improves on domestic and international markets and learning potential dissipates. Using theory‐consistent empirical specifications, I find a strong, robust negative relationship linking tariff rates to trade performance for manufactured products that matured during the first decade after Canada prioritized protectionist policy objectives in 1879. This relationship also holds at a more aggregate industry level, where I can use other measures of maturity, control for import penetration, use historically contemporaneous trade elasticity estimates, link trade performance to trade restrictiveness and effective rates of protection and where I can instrument for import penetration and trade performance using a two‐stage IV–GMM estimation approach. The results suggest that after 1890 the Canadian government carefully cut tariffs on products produced by maturing Canadian producers and this retreat from protectionism significantly lowered the static deadweight losses resulting from Canadian trade policy during the post‐1890 period.  相似文献

HR and analytics: why HR is set to fail the big data challenge   总被引:1,自引:0,他引:1       下载免费PDF全文
The HR world is abuzz with talk of big data and the transformative potential of HR analytics. This article takes issue with optimistic accounts, which hail HR analytics as a ‘must have’ capability that will ensure HR's future as a strategic management function while transforming organisational performance for the better. It argues that unless the HR profession wises up to both the potential and drawbacks of this emerging field and engages operationally and strategically to develop better methods and approaches, it is unlikely that existing practices of HR analytics will deliver transformational change. Indeed, it is possible that current trends will seal the exclusion of HR from strategic, board‐level influence while doing little to benefit organisations and actively damaging the interests of employees.  相似文献

This paper is divided into two distinct parts and within these parts it follows the following lines of progression. The major division in the paper is between a look at the accepted theory that underpins any research in this area with comments on its likely effects on the organizations under scrutiny, and a look at the case studies that were constructed as a result of undertaking research into several hotel and leisure companies with the aim of gaining a representative cross-section of the industry and its budgetary control techniques.  相似文献

The development of an effective spatial data infrastructure (SDI) often occurs in a fragmented organizational environment requiring a high level of inter-organizational collaboration. Different organizations from various jurisdictions need to work together closely when agreeing on how they will jointly register, store, use and share data and how they will make their data available to the wider society. However, this collaboration is generally regarded as very difficult. For example people often resist data sharing across organizational boundaries due to loss of control, power and independency. Organizational issues are thus considered one of the fundamental constraints to inter-organizational sharing of spatial data.  相似文献
