Managers engaged in net-enabled business planning seek metrics to help them analyze the success of their e-business investments. Likewise, researchers require metrics to build analytical models and conduct empirical research on the impact of e-business strategies on firm performance. In this article, the authors develop a comprehensive E-Valuation Framework for identifying net-enabled applications and their resulting user-based functionalities for activities across the value chain. The authors propose that the real value from net-enabled applications can be found in functionality interactions, where one application enables or enhances functionality in another application. The comprehensive framework can be used to generate three types of metrics managers can use to evaluate their net-enabled strategic initiatives. Further, a classification of net-enabled organizations provides the basis for selecting applications critical to a firm's strategic thrusts. We make use of the resource-based view of the firm and real-options analysis to discuss how successful application deployment is based on the resources and assets the firm possesses as well as managing the rollout of an applications portfolio over time. The framework allows managers to map their organization's net-enabled initiatives into a coherent, easily understood visual representation and provides direction for researchers evaluating the efficacy of net-enabled business strategies. 相似文献

Applying the characterization results from Mitra and Sorger (1999), we show that topological chaos is a robust phenomenon in standard aggregative growth models even under arbitrary mild discounting. Furthermore, we state exact discount factor restrictions, under which two of the most popular examples of chaotic dynamics, the logistic map and the tent map, can be optimal policy functions of aggregative growth models.

On the faustmann solution to the forest management problem 总被引:1,自引:0,他引:1
This paper is concerned with optimal solutions to the forest management problem when future utilities are undiscounted. By examining asymptotic properties of such solutions, we find that (i) if the utility function is linear, then the Faustmann periodic solution is optimal; (ii) if the utility function is increasing and strictly concave, an optimal solution converges to the maximum sustained yield solution, which we characterize as a golden rule. These results may be viewed as a possible resolution to the debate in forestry economics about what constitutes an optimal policy in forest management. 相似文献

In the aftermath of the 2008 financial crisis, the entire Indian banking industry was paralysed and their performance was shattered by the unfolding of enormous cases of Non-performing Assets (NPA). The study estimates the operating efficiency of 40 Indian banks for 5 years (2011–15) as a proxy of performance measure using the output-oriented DEA-BCC model. We find that nearly 62% of the state-owned banks and 47% of the private banks are inefficient indicating that the inefficient banks need to reduce their inputs or improve their output to become efficient. The study further investigates the relationship between intellectual capital (IC) and bank performance using a truncated regression model. The regression results show that out of the three components of intellectual capital, only human capital efficiency is positively and significantly associated with operational efficiency while structural capital and finance capital have a negative impact on the efficiency of banks. The study concludes that to achieve competitive edge banks should invest in their human capital. The results are robust in the case of financial variables taken as a proxy for performance. 相似文献

On the Welfare Significance of National Product for Economic Growth and Sustainable Development 总被引:1,自引:0,他引:1
This paper formulates an investment value transversality condition in a continuous-time growth model, which characterizes competitive paths along which current net national product measures the welfare achieved along the path. This transversality condition requires that the present value of net investment goes to zero asymptotically. An example provided shows that, in general, competitive paths do not necessarily satisfy this condition. It is also shown that, in a standard growth model including an exhaustible resource as an essential factor of production, competitive paths always satisfy this condition. Implications regarding national income accounting procedures and sustainable development policies are discussed.

The effects of firm and job characteristics on the wages of blacks and whites are analyzed using data from the 1988 National
Longitudinal Survey of Youth [Bureau of Labor Statistics, 1997]. This study focuses on 2,370 full-time private sector employees.
The results show that, first, blacks are disproportionately employed in large establishments despite their lower cognitive
achievements. Second, blacks do not enjoy significant wage premiums associated with supervisory positions. Third, although
the wage gap between blacks and whites is reduced considerably, controlling for education and cognitive skills, the gap increases
significantly when structural attributes are included in the wage regressions despite the large wage premiums associated with
employment in large establishments. 相似文献

We construct the first direct classification of goods as luxuries or necessities that is compatible with international trade data. We then use it to test an idea that has not been tested directly in the literature: Countries' income distributions are important determinants of their import demand, and, in particular, of the difference in their import demands of luxuries versus necessities. We interpret this result with the aid of a model in which preferences are nonhomothetic, thus relaxing a long-held and standard—but empirically dubious—assumption in the theory of international trade. Our model is strongly borne out by the results: Imports of luxuries increase with the importing country's inequality, and imports of necessities decrease with it. Our calculations imply that if income distribution in the United States became as equal as in Canada, the United States would import about 9-13% fewer luxury goods and 13-19% more necessities. 相似文献

NIIT is a highly successful for-profit education company with global reach, which grew by capitalising on the failings of the Indian state education system to provide employable graduates in computer education. Dr Mitra describes the company, then explores the changing forms of universities, the rôle of the private sector in these and the challenges of the future. He concludes by outlining how the 'NIIT Academy' is emerging as a possible model for universities for the next century. 相似文献

The effect of advertising on consumer welfare has been the subject of dispute among economists, arising largely from disagreement among scholars regarding the persuasive versus the informative role of advertising. This paper reports two experiments that explore the welfare implications of advertising effects. Experiment 1 shows that the same advertisements can either increase or decrease prices paid for selected brands, depending on the degree to which the choice situation requires brands to be recalled in order to be considered. However, an increase in prices paid caused by advertising does not necessarily imply detrimental effects on consumer welfare. Experiment 2 shows that, even under circumstances in which differentiating advertising leads consumers to select brands with higher average prices, it can provide useful information to consumers that allows them to make purchases that are more in line with their personal tastes than are the choices of consumers not exposed to the advertisements. 相似文献
