Nanotechnology is the first major worldwide research initiative of the 21st century. Nanotechnologies are applied to cross industrial problems and are a general purpose technology that acts as both a basis for technology solutions or at the convergence of other enabling technologies, like biotechnologies, computational sciences, physical sciences, communication technologies, cognitive sciences, social psychology and other social sciences. Nanotechnologies are pervasive solution vectors in our economic environment. It is necessary to develop new methods to assess nanotechnologies development to better understand nanotechnology based innovation. As general purpose and enabling technologies, nanotechnologies reveal commercialization processes, from start-ups to large firms in collaboration with public sector research, and which lead to changing patterns of industrial organization which influence public policy initiatives to foster their development. 相似文献

This research examines the role of imagination difficulty on the evaluation of really new products (RNPs) in comparison with incrementally new products (INPs). We extend past research on accessibility utilizing an anticipatory approach where consumers look forward and generate mental images for future product usage. We found that the role of imagination changes based on the newness of the product. Specifically, for RNPs, imagination difficulty is perceived to be diagnostic in product assessment, and thus, higher imagination difficulty leads to lower product evaluations. However, for INPs, which are shown to be less susceptible to context effects, imagination difficulty has a limited impact on product evaluations. In addition, we show that the effect of imagination difficulty on the evaluation of RNPs is moderated by the level of involvement of the consumer. Research and managerial implications are discussed. 相似文献

This paper characterizes the rate of convergence of discrete‐time multinomial option prices. We show that the rate of convergence depends on the smoothness of option payoff functions, and is much lower than commonly believed because option payoff functions are often of all‐or‐nothing type and are not continuously differentiable. To improve the accuracy, we propose two simple methods, an adjustment of the discrete‐time solution prior to maturity and smoothing of the payoff function, which yield solutions that converge to their continuous‐time limit at the maximum possible rate enjoyed by smooth payoff functions. We also propose an intuitive approach that systematically derives multinomial models by matching the moments of a normal distribution. A highly accurate trinomial model also is provided for interest rate derivatives. Numerical examples are carried out to show that the proposed methods yield fast and accurate results. 相似文献

In January 1999, President Carlos Menem suggested replacing the Argentine peso with the U.S. dollar. President Menem's announcement has sparked a debate throughout Latin America and Eastern Europe about what has been termed "dollarization." That debate prompted U.S. Treasury Secretary Robert Rubin to deliver a major policy speech on alternative exchange-rate regimes on April 21, 1999 and the U.S. Senate Banking Committee to hold dollarization hearings the following day featuring Fed Chairman Alan Greenspan and Deputy Secretary of the Treasury Lawrence Summers.
This article presents a case for officially dollarizing Argentina. Dollarization is not new. Unofficial dollarization is widespread in emerging market countries; in fact, as much as 70% of the stock of U.S. dollars now circulates abroad. Twenty-eight countries and dependent territories are officially dollarized. Although official dollarization would result in Argentina losing seigniorage of about 0.22 percent of GDP, the author estimates that this cost would be more than offset by a reduction in interest rates that would increase Argentina's trend rate of GDP growth by about two percent.
After debunking the most common criticisms of dollarization, the article closes by offering recommendations about the specific form of dollarization and presenting a detailed dollarization statute for Argentina. The author proposes a competitive currency regime for Argentina, one in which all foreign money would be legal tender. 相似文献

This paper analyzes a simple model that captures the relationship between institutional quality, the shadow economy, and corruption.
It shows that an improvement in institutional quality reduces the shadow economy and affects the corruption market. The exact
relationship between corruption and institutional quality is, however, ambiguous and depends on the relative effectiveness
of institutional quality in the shadow and corruption markets. The analytics also show that the shadow economy and corruption
are substitutes. The predictions of the model are empirically tested and confirmed. 相似文献

In a previous article the authors provided an introduction to using the internet as a resource for business ethics. In this sequel they look at newsgroups and chatrooms, and conclude by looking at the websites of Shell and a Shell critic on the controversial ethical aspects of its corporate policy and behaviour.

This paper reexamines the determinants of the number of analysts following a firm using econometric models based on count distributions. We replicate Bhushan's (1989) analyst-following study to demonstrate the effects of using count-data econometrics, in lieu of OLS, in studying phenomena where the dependent variable ranges among nonnegative integers. In contrast with the original paper, our findings indicate the number of institutional investors is inversely related with analyst following. We also provide econometric evidence to support the preferred use of the negative binomial model in estimating cross-sectional, analyst-following regressions. 相似文献
