On Patent Licensing in Spatial Competition 总被引:2,自引:0,他引:2
We consider the optimal licensing strategy of an outsider patentee as well as an insider patentee in a linear city framework where firms compete in price. We show that offering royalty is best for an outsider patentee for both drastic and non-drastic innovations. For an insider patentee, offering no license is the best when the innovation is drastic, while royalty is optimal when the innovation is non-drastic. The incentive for innovation is higher for an outsider patentee compared to an insider patentee. The overall increase in welfare due to an innovation is the same for both outsider and insider patentees. 相似文献

The authors study the acceptance of family planning methods according to the level of couple's literacy in 14 states in India during 1986-87, using the Lorenz curve. The Gini Concentration Ratio and Index of Dissimilarity were calculated by level of couple's literacy for vasectomy, tubectomy, IUD, and all method combined. Firstly, analysis found literates to have accepted vasectomy and IUD more than tubectomy. Secondly, among the 3 methods, a high Gini Concentration Ratio was found for vasectomy when the wife was literate. Moreover, when the wife was literate, the Gini Concentration Ratio of IUD acceptance was higher than the acceptance of IUD by the wife whose husband was literate. Thirdly, the same trend was observed when the husband was illiterate. It is therefore clear that the level of a woman's literacy is a key factor in securing the acceptance of male or female methods of family planning. Planners should therefore concentrate on literacy programs for females independently of their age. Increasing the level of female literacy may ultimately help improve the understanding of family planning methods, while these women may also motivate their husbands to undergo vasectomy which will ultimately foster the success of the family planning program. 相似文献

Many tasks and decisions in business, including management consulting, are performed in group settings. Computer-mediated communication (CMC) tools (e.g., Lotus Notes) are increasingly being used by businesses to support teams in a variety of settings. Considerable research in information systems has demonstrated the advantages of electronic brainstorming (EBS) for generic tasks involving only divergent thinking. However, it is unclear whether the benefits of CMC extend to tasks that require both divergent and convergent processes. Per task–technology fit theory (TTF) (Zigurs and Buckland 1998), the use of computer-based group communication support tools, including chat systems in wide-spread use today, may be less effective for convergent processes than for divergent processes. This study experimentally compares the performance of computer-mediated and face-to-face (FTF) teams on tasks requiring both divergent and convergent processes. Consistent with theoretical predictions, the results revealed that computer-mediated teams outperformed FTF teams in the divergent aspects of the tasks, while FTF teams outperformed computer-mediated teams in the convergent aspects of the tasks. 相似文献

We examine intertemporal asset pricing when short sales areconstrained in proportion to the value of an investor's portfolio.All assets' prices exceed every investor's marginal utilityof consumption-based valuation of the associated dividends ifevery investor finds himself constrained in some asset in somestate; we exhibit such an equilibrium. An asset's price decomposesinto three (investor-specific) components: the consumption valueof its dividends, a speculative value premium, and a collateralvalue premium. The validity of the no-arbitrage pricing approachis shown to depend critically on the difference between realsecurities and their synthetic counterparts. 相似文献

By employing unit root testing and cointegration procedures, this paper is the first study of its kind to present empirical
evidence showing higher inflation rate, lower unemployment, and increased real per capita gross domestic product decreased
the poverty rate among African American families during the 1966–99 period. The findings, estimated using the Phillips-Hansen
fully modified OLS estimator, are also consistent with results obtained using Johansen’s maximum likelihood cointegration
procedure. Long-run Granger causality, inferred by the estimated error-correction model, suggests that the African American
poverty rate is not weakly exogenous and will respond to policy intervention. 相似文献

In this paper, the recently developed panel unit root and the Pedroni cointegration tests are applied to empirically examine
the validity of the Feldstein–Horioka puzzle (F–H puzzle) for a heterogeneous panel of 14 Latin American and five Caribbean
countries over the period, 1960–2002. The findings indicate that in these countries, the long-run solvency condition is maintained.
Finally, employing the Pedroni panel group FM-OLS estimator (2000, 2001), it is found that the statistically significant estimated
savings-retention coefficient for the panel is relatively small indicating that the F–H Puzzle is not valid and thus implying
the prevalence of a moderate degree of capital mobility.

Current auditing standards require auditors to conduct a fraud brainstorming session aimed at considering ways in which the audit client's financial statements might be fraudulently misstated. Lynch et al. (2009) document that computer-mediated fraud brainstorming is significantly more effective than face-to-face brainstorming for generating relevant fraud risks. In this study, we code and analyze process-level data from the Lynch et al. (2009) study to understand the factors contributing to the greater effectiveness of electronic fraud brainstorming. Specifically, we conduct mediation analysis to discern the degree to which equality of participation and two measures of task focus contribute to greater fraud brainstorming effectiveness when using a computer-mediated communication system compared to traditional face-to-face brainstorming. We also examine participants' perceptions of ease of system use, satisfaction with the process, and satisfaction with the outcome. Overall, the results indicate that the primary reason for the greater effectiveness of electronic fraud brainstorming is the greater degree of task focus as revealed through the length of comments made when using computer-mediated fraud brainstorming. In an absolute sense, participants using electronic brainstorming felt that their brainstorming mode was easy to use and they were satisfied with the process and outcome. The primary contribution of this study is in enhancing our understanding of precisely why computer-mediated fraud brainstorming outperforms face-to-face fraud brainstorming. 相似文献

Ethical Challenge to Businesses: The Deeper Meaning 总被引:1,自引:0,他引:1
Today, ethics has become an important dimension for businesses. Broadly, there are two lines of thought on this issue. The first one suggests that ethical issues have to be resolved through development of appropriate ethical standards at personal or organizational level. The second one emphasizes the process of developing ethical standards rather than the standards themselves. This paper argues that the latter line of thought, when taken forward, implies that ethical dimension is essentially challenging businesses to transform themselves and their people at a very fundamental level in order to evolve continuously to higher levels of perfection. The deeper significance is that in future, businesses will play a dominant role in bringing forth the human spirit, an aspect that is hitherto perceived to be in the purview of other human activity systems like the Church or family. This restructuring at the societal level is probably the most fundamental message of this age of growing interdependence. 相似文献

Development and validation of a measurement instrument for studying supply chain management practices 总被引:1,自引:0,他引:1

It is widely argued that competition is no longer between organizations, but among supply chains. Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage and improving organizational performance. This research conceptualizes, develops, and validates six dimensions of SCM practices (strategic supplier partnership, customer relationship, information sharing, information quality, internal lean practices, and postponement). Data for the study were collected from 196 organizations and the measurement scales were tested and validated using structural equation modeling. It is hoped that this study will provide a parsimonious measurement instrument to assess the performance of the overall supply chain. 相似文献
