We analyse the skill premium and the growth rate in an innovator-imitator general equilibrium growth model assuming (i) internal costly investment in both physical capital and R&D, (ii) complementarities between intermediate goods in production and (iii) technological-knowledge diffusion. We find that in the imitator country these three elements influence the economic growth rate and the skill premium. In the innovator country, while the growth rate is affected by costly investment and complementarities, the skill premium is not affected by any of our assumptions. It depends solely on the productive advantage of high-skilled over low-skilled labour, which suggests that the sustained increase in the skill premium observed in several developed countries over the last three decades may have been due to increases in such productive advantage. 相似文献

Purpose: This article analyzes the effects of perceived value, satisfaction, and switching barriers on price tolerance. It also examines the moderating effect of switching barriers. Methodology/Approach: Empirical research was conducted by collecting information from a sample of 326 major gas and electricity consumers in a newly liberalized industrial market with a high concentration of suppliers. Findings: Switching barriers are the main antecedent to price tolerance. Price tolerance of industrial customers depends directly on switching barriers more than on satisfaction. The customer satisfaction construct is a necessary but not sufficient predictor of price tolerance. While satisfaction has an effect on price tolerance, the effect of perceived value on price tolerance is only indirect through satisfaction, even though it may produce positive direct effects when there are high switching barriers. Originality/Value/Contribution: For the first time in a B2B framework, the moderating effects of switching barriers on the relationship between perceived value, satisfaction, and price tolerance have been analyzed. 相似文献

Only a small number of works in the literature examines the role of familiarity in the perception of products from a specific origin, despite the importance of this variable in the formation of product image and its effects on consumer behavior. The current work aims to fill this gap in the literature by carrying out a cross-national analysis of consumers' image of fruit and vegetables that includes a defined origin. For this purpose, the authors examine the influence of product cues on the formation of a global image of the product, and considers the moderating role of familiarity in this relation. The results indicate that product familiarity has an effect on the relation between the product cues and the image perceived by the consumer, and that differences exist between the nationalities considered. 相似文献

SUMMARY Store brands, when moving upscale, inevitably relinquish their value for money appeal and therefore require some quality dimension to compete. This article is proposing that the promise of “generous” use-by dates as a surrogate for quality could be considered as a positioning plank to promote store brands as alternatives to manufactured brands. Logit analysis is employed to explain shoppers' perceptions and responses to use-by dates, of products that they regularly buy, and of alternative products that they have never bought before if the use-by dates of their regular items are perceived to be too short. 相似文献

The objective of this article is to identify the factors that have brought about the greatest degree of competitiveness in
some of the principal agrifood cooperative groups in the European Union (EU), using pertinent case studies from a range of
sectors including the dairy, meat and fruit and vegetable sectors from three EU member states: Holland, Ireland and Denmark.
With this purpose in mind, seven cases were identified for inclusion: Kerry Group, the Irish Dairy Board, Arla Foods, The
Greenery BV, Danish Crown, Agrifirm and DLG. The article identifies the main barriers and problems faced by this type of cooperative
and shows the strategies developed by leading cooperatives in their sector within the current comparative context and familiarizes
readers with the different growth models these cooperatives use to achieve and maintain their market standing. 相似文献

The German energy market is facing several challenges due to changes in regulation, technical advancements as well as increasing
energy costs and climate achievements like CO2 reduction. This results in changing requirements for companies in the energy market and thus business information systems,
which support their core tasks and processes. Software product managers in energy and software developing companies in charge
of driving the functional development of information systems have to deal with these challenges and need to develop new information
systems or enhance existing ones. Conceptual models proved helpful to design and implement information systems within several
industries. However, identification and management of models as well as impact analysis of model changes results difficult.
This contribution describes methods to construct, use and maintain a domain specific reference model catalogue to support
requirements analysis for software product manager in the German electricity and gas market. 相似文献

A static model is developed to analyse the incumbent’s innovation strategy under monopoly and duopoly. A number of potential
objectives for the incumbent are modelled here, including the maximization of revenue, profit, and welfare (which are common
among the network industries). Its marginal cost depends upon investment in new technologies and processes. The incumbent
chooses its price and its level of investment in innovation. The incumbent’s elasticity of demand under both market structures
and the incumbent’s market share under duopoly determine which market structure creates more incentives to innovate. For certain
values of these variables, duopoly provides more incentives to innovate than monopoly. As expected, the incentives to innovate
increase when the incumbent places greater weight on social welfare. 相似文献

A model for negotiation is developed upon the basis of a previous model called Fuzzy Negotiation Solution by Knowledge Engineering.
The new model, called Compensatory Negotiation Solution by Knowledge Engineering and FNSKE are based on the combination of
knowledge of experts in negotiation, rather than on classical notions of rationality. The experts in negotiation present four
propositions in a non-mathematical way and with a natural language, according to the theory of Knowledge Engineering. In the
CNSKE model, knowledge is represented through logic predicates, and the calculations are made using the Compensatory Fuzzy
Logic system. CFL is a system whose operators satisfy the axioms of Utility. The CFL operators, especially because of the
compensation property, are more adequate than the norm and co-norm’s operators to model human decision-making, according to
empirical results. The Good Deal Index in CNSKE is statistically estimated from the GDI in FNSKE. This is a quantitative index,
which provides the solution concept. The fuzzy function f(C) represents the likelihood the players of a coalition C to reach an agreement into this coalition. Counterpart Convenience Indexes 1, 2 allow each player to select the best coalition
for negotiation. The advantage of CNSKE over FNSKE is that the idempotency of conjunction and disjunction operators give every
membership function -obtained from the predicates- the possibility to be interpreted by itself. Hence, the truth-values of
the CNSKE membership functions can be semantically interpreted. In addition, CNSKE can be easily applied to solve real negotiation
problems. 相似文献

The purpose of this study is to examine how workgroup diversity can be managed through specific strategic human resource management
systems. Our review shows that ‘affirmative action’ and traditional ‘diversity management’ approaches have failed to simultaneously
achieve business and social justice outcomes of diversity. As previous literature has shown, the benefits of diversity cannot
be achieved with isolated interventions. To the contrary, a complete organizational culture change is required, in order to
promote appreciation of individual differences. The paper contributes to this discussion by exploring the implications of
this change for human resource management, and explaining how the systems of practices should be changed when they are directed
to diverse groups. The model designed to test this notion includes: (1) demographic and human capital diversity as independent
variables, (2) group performance (measured as innovation outcomes) as the dependent variable and, (3) the orientation of the
strategic human resource management system as a potential moderator of this relationship. The main conclusion of the empirical
analysis developed is that different patterns of human resource management practices can be used, depending on the type of
diversity that the organization faces, and the specific effects that it wishes to manage. Concretely, three alternative management
systems are identified in this paper, with different moderating effects. This result has interesting implications for human
resource management professionals, explained in the last section. The limitations of this study are also discussed, as well
as some issues that future research in this field should address. 相似文献

Geo-collaborative systems address the computational support to situations where people are working in different locations, gathering geographically-related data in the field and sharing knowledge. We propose a conceptual framework identifying the design issues that fundamentally set the stage for eliciting the requirements of geo-collaborative systems. The conceptual framework has five elements: places, teams, tasks, artifacts and geo-referenced knowledge. We also highlight two important relationships between some of these elements: (1) a task-artifact relationship, related with the need to increase the organizational decision making abilities through concerted efforts; and (2) an artifact-knowledge relationship, related with the need to support mechanisms for jointly understanding geo-referenced data. The conceptual framework was applied to the development of a groupware tool aiming to increase the productivity of the geological mapping process followed by a national agency with competence in this area. The paper describes in detail how the conceptual framework influenced the groupware design. The obtained results indicate that the framework can focus the designers on the human aspects of geo-collaboration and guide them through the initial design stages. 相似文献
