Managing knowledge: changing ways of wealth creation   总被引:1,自引:0,他引:1  
R&D will have to be at the core of enterprises which expect to prosper in the new economy. Investors now realise there is a link between R&D investment and long-term growth, so share prices are boosted for companies which know how to extract value from R&D spending. The IT and pharmaceutical industries are probably the leaders in new ways of managing knowledge more effectively.  相似文献

The paper estimates both long-run reserves and long-run money demand equations using the multivariate cointegration approach. An economic model is constructed, based on the monetary approach to balance of payments in which the monetary authorities can control money supply through changes in bank credit. The vector auto-regressive methodology is used to derive latent equilibrium relationships, and the short-run error correction equations are estimated for both nominal money stock and reserves. A response function for the short-run changes in bank credit is developed. Given the institutional system and slow adjustments, a response function of changes in bank credit to lagged changes in reserves performs well for the period 1960–88.  相似文献

The purpose of the present research is to study target and acquirer shareholder wealth effects of acquisition announcements in which the target is financially distressed. The abnormal returns and the dollar abnormal gains to both the target and acquiring firms are examined according to whether the mode of acquisition is a merger or a tender offer. A regression analysis is also undertaken to examine the importance of the mode of acquisition, an industry effect, and tax variables in determining the abnormal dollar gains in acquisitions of financially distressed targets.  相似文献

Indian popular cinema, at the present juncture, is caught in a fix marked by two opposite trends—the overall decline in quality of the modern film resulting in rejection by audiences (as seen in endless commercial failures) and the nostalgic reverence among people about the classic films of earlier years, which had entertained and mesmerised them in a discourse that was beautiful, exciting and emotionally satisfying. This paper argues that the current decline in quality is part and outcome of the wider globalisation processes, consequently delinking cinema from the earlier creative roots. In this context, it makes some projections about the future of this cinema (and television) and suggests a set of future options to resurrect it from its present decline and to help the medium reinvent its past glory and social relevance.  相似文献

This study considers agritourism and off‐farm work as income diversification choices simultaneously and analyzes factors influencing such choices. Further, the study assesses the impact of agritourism, off‐farm work, and both on gross cash farm income and total farm household income. We utilized large set of nationwide farm survey data and selectivity‐based multinomial choice model. An important finding of our study is that small farms have higher household income if they choose both income diversification strategies rather than a single strategy. Results suggest that education, age of the operator, financial condition, and location of the farm are important factors driving income diversification alternatives. Finally, our study indicates that accounting for selectivity is essential to ensure unbiased and consistent estimates.  相似文献

This study uses a two-stage econometric framework with farm household level data to investigate whether off-farm work of operators and spouses influences healthcare expenditures and retirement savings. Results indicate that agricultural policy discourages off-farm work by farm operators and spouses. However, off-farm work decisions of farm couples significantly decrease healthcare expenditures and increase retirement savings of farm households in the US. The effect of farm spouse’s off-farm employment on household retirement saving is more pronounced. These conclusions can extend to middle-income countries where off-farm work may enable farmers to afford better healthcare and retirement pension plans.  相似文献

This study examines the impact of auditor quality on financial covenants in debt contracts. We conjecture that high‐quality auditors have two related effects on these debt covenants: (i) they encourage fewer and less restrictive covenants by providing assurance to lenders at contract inception and, consequently, (ii) they ensure a lower probability of eventual covenant violations. Consistent with the conjectures, we find that auditor quality is negatively associated with the intensity and tightness of financial covenants. Specifically, high‐quality auditors are associated with fewer covenants (especially performance covenants) and less binding covenants. Additionally, we find that auditor quality is negatively associated with the likelihood of covenant violations. In an ancillary test, we provide evidence that high‐quality auditors mitigate the detrimental effect of covenant violations on the cost of borrowing. Together, these findings highlight the important role of auditors in debt contracting.  相似文献

A successful R&D manager is, in many ways, an agent of change. R&D managers must respond effectively to changes in domestic and global competition, product and process technologies, customer requirements, regulatory matters, and senior management's perception of the role R&D plays in a firm. The responses to these changes flow downstream from R&D to other parts of the organization, in the form of new materials, methods, processes, and products. To help us understand the changes facing R&D management, Ashok K. Gupta and David Wilemon present the results of a study that examines the ideas and experiences of 120 R&D directors from technology-based companies. The study explores the major changes that R&D management has undergone in recent years, the changes R&D managers expect to encounter during the next few years, and the causes of those changes. The respondents also identify the skills and knowledge they view as necessary for effective R&D management, and they assess their organizations' capabilities in those areas. According to the respondents, major changes that R&D has encountered include increased emphasis on such issues as cross-functional teamwork, R&D's contribution to both short- and long-term business results, R&D's capability to quickly bring to market new products that customers value, efficient use of R&D resources, and R&D alliances. Other changes noted by respondents include greater pressure to find new markets, increased attention on the effective management of technical personnel, and increased regulations and sensitivity to environmental issues. The knowledge domains that the respondents highlighted as having the greatest effect on R&D performance include such capabilities as understanding customer needs, monitoring market developments, commercializing new technologies, building cross-functional teams, managing multiple R&D projects, and accelerating new product development. According to the respondents, the largest gaps between required and current capabilities exist in several of the areas listed as being most important to effective R&D management, including monitoring market developments that can affect R&D activities and overall business performance, maintaining a spirit of inquiry while ensuring that R&D contributes to overall corporate performance, developing technology commercialization capabilities, fostering mutually profitable strategic alliances, and accelerating the development and commercialization of new products.  相似文献

We present simple and fast algorithms for computing very tight upper and lower bounds on the prices of American Asian options in the binomial model. We introduce a new refined version of the Cox-Ross-Rubinstein (1979) binomial lattice of stock prices. Each node in the lattice is partitioned into nodelets, each of which represents all paths arriving at the node with a specific geometric stock price average. The upper bound uses an interpolation idea similar to the Hull-White (1993) method. From the backward-recursive upper-bound computation, we estimate a good exercise rule that is consistent with the refined lattice. This exercise rule is used to obtain a lower bound on the option price using a modification of a conditional-expectation based idea from Rogers-Shi (1995) and Chalasani-Jha-Varikooty (1998). Our algorithms run in time proportional to the number of nodelets in the refined lattice, which is smaller than n4/20 for n > 14 periods.  相似文献
