Distribution dynamics is a method for studying the evolution in time of an entire cross‐section distribution and has been initially employed to assess cross‐country convergence of per capita incomes. It has subsequently seen a widespread application in many different economic areas. When describing the law of motion of the distribution as a Markovian stochastic process, working in a discrete state‐space set up has several advantages, but the arbitrary discretisation of a continuous state‐space process has the undesired effect of removing the Markov property. This paper outlines a rigorous method for discretising a continuous state‐space Markov chain. The method is then applied to the distribution of per capita income across countries to reassess the (non‐) convergence phenomenon. It is found that the long run polarisation of per capita incomes across countries emerges even more dramatically than in previous studies.  相似文献

Much is currently being written about the need to encourage employees to share knowledge in order for companies to maintain a role as an intelligent organization in a technologically sophisticated environment. However, there is little written of the relationship between employee rights to satisfactory employment conditions, employee responsibilities in decision-making, and employee willingness to share their knowledge collaboratively. This paper seeks to redress this gap by discussing the importance of the relationship between employee rights and responsibilities and employee willingness to share knowledge. The reaction of a group of employees (academics) employed in an Intelligent Organization (university) to a reduction in their rights and responsibilities is discussed in order to design a framework of employee rights and responsibilities required for knowledge sharing in intelligent organizations.  相似文献

Zusammenfassung Die Frage, warum bestimmte Informationen oder Werbemittel mehr und andere weniger Überzeugungskraft aufweisen, beschäftigt die Marketingforschung und verwandte Gebiete schon seit geraumer Zeit. Eine dieser Thematik zuzuordnende Forschungsrichtung, die in den letzten zwanzig Jahren eine Forschungstradition entwickelte, ist die Imagery-Forschung. Autoren, die sich dieser Forschungsrichtung zuwenden, erklären die Wirkung von Informationen damit, dass die Elemente in dieser Information Gedächtnisinhalte oder Imaginationen (Fantasien bzw. Vorstellungen) bei den Rezipienten auslösen, die ihrerseits die Bewertung des relevanten Meinungs- oder Werbeobjekts beeinflussen. In diesem Beitrag wird zunächst dargestellt, welche Hypothesen im Mittelpunkt der neueren Imagery-Forschung stehen. Der Nutzen dieser Überlegungen besteht zum Beispiel für die Werbepraxis darin, dass konkrete Hinweise für die Werbegestaltung gegeben werden. Anschließend wird der Stand der empirischen Forschung zu diesen Hypothesen vorgestellt. Hier zeigt sich, dass die empirischen Erkenntnisse hinter dem Stand der theoretischen Forschung zurückgeblieben sind. Am Ende dieser Abhandlung werden Vorschläge unterbreitet, wie die theoretischen Überlegungen einer weitergehenden Analyse unterzogen werden können. JEL classifications M31, M37  相似文献

In this paper, we aim to include rule making, implementation, monitoring and enforcement costs into the cost comparison of policy instruments. We use a simple partial equilibrium model and apply it to the textile industry. The model includes discrete abatement functions and costly monitoring and enforcement. The case study uses individual firm data to simulate the differences in abatement costs and compliance decisions between firms. We compare combinations of regulatory instruments (emission taxes, emission standards and technology standards) and enforcement instruments (criminal fines, civil fines and transaction offers). We show that the inclusion of information, monitoring and enforcement costs indeed alters the relative cost efficiency of the different instruments.  相似文献

Profiles of inventors' technological competence are a valuable source of information for decision-making in research and development (R&D) management, e.g. concerning inventor assessment, human resource development and R&D team-building. In the following exposition, a new method of inventor profiling will be put forward, which is based in particular on semantic patent analysis and multidimensional scaling. First, in the course of semantic patent analysis, specialized software, equipped with a natural language processor, reads the patent text transferring the contents into a subject–action–object–format (SAO). The extracted SAO structures are then used to create similarity matrices for patents or patent sets, respectively, according to a specific similarity value. Subsequently, an inventor competence map can be produced by means of multidimensional scaling.
The benefits of this method for R&D-related issues in human resource management will be illustrated by the example of a German mechanical engineering company. Two distinct types of profiles were generated and tested: (i) the profile of a single key inventor and (ii) a profile of key inventor sets. The single key inventor profile gives information on the range of competence, i.e. the homogeneity or heterogeneity of a certain inventor's competences, providing far more detailed insights than resorting to bibliographic data like international patent classification (IPC) classes or citations, whereas the latter kind of profile establishes the position of a certain key inventor in relation to others, helping to highlight specific groups of inventors and their domains. These results are clearly apt to support human resource management.  相似文献

A survey (n = 151) explored consumers’ experiences with wine-on-tap, a current trend in the U.S. foodservice industry. Wine consumers’ innovativeness (R2 = .49) was explained by wine involvement, opinion leadership, and usage of information sources. Those who recently tried wine-on-tap (n = 43) were significantly more innovative (innovators) than those who never tried it (noninnovators). Furthermore, noninnovators expected to pay significantly less for a glass of wine-on-tap when compared with wine poured from a bottle. Contrary to expectations, the driving force for noninnovative behavior is lack of availability and awareness as opposed to a lack of interest in wine-on-tap.  相似文献

The concepts of isotropy/anisotropy and separability/non‐separability of a covariance function are strictly related. If a covariance function is separable, it cannot be isotropic or geometrically anisotropic, except for the Gaussian covariance function, which is the only model both separable and isotropic. In this paper, some interesting results concerning the Gaussian covariance model and its properties related to isotropy and separability are given, and moreover, some examples are provided. Finally, a discussion on asymmetric models, with Gaussian marginals, is furnished and the strictly positive definiteness condition is discussed.  相似文献

Amidst the IASB's post-implementation review of IFRS 8, we examine how the standard's adoption changed the reporting of segments by European blue chips (i.e. companies comprising the top tier index of 14 European stock exchanges). We focus on anticipated benefits articulated in the IASB's Basis for Conclusions and concerns expressed by IFRS 8 opponents.In addition to convergence with U.S. GAAP, IFRS 8 results in the reporting of significantly more operating segments on average. However, most companies report the same number or fewer segments. Refuting claims regarding the loss of geographic data at the entity-wide level, we identify an improvement in the fineness of disclosures and a significant increase in the disclosure of geographic groupings. We do not identify an improvement in consistency of segment disclosures with other sections of the annual report, which is due to the consistency already achieved under IAS 14R.IFRS 8 results in a significant decline in the number of reportable segment information items (notably liabilities) and a significant decline in the reporting of capital expenditures at the entity-wide level. Furthermore, adoption of the standard produces a lack of comparability in segment profitability measures and extensive reporting of non-IFRS measures. However, almost all companies report a measure of segment profitability tied to a number on the consolidated income statement or reconciled to the income statement.  相似文献
