We study the exploitation of a common groundwater resource, first as a static and then as a differential game, in order to take into account the strategic and dynamic interactions among the users of the resource. We suppose that firms can form coalitions or can decide not to cooperate. The non-cooperation regime is characterized by pumping that lead to depletion of the aquifer; the cooperation preserves the resource. Open-loop and feedback equilibria have been computed and compared in order to characterize the existence of cooperators and defectors in water resources management. 相似文献
State-owned enterprises (SOEs) are commonly associated with undue advantages due to preferential treatment by the state. Simultaneously they are often quoted as handicapped given the notorious state interference, management problems and agency tensions. They used to be regarded as a mainly domestic issue but in the context of globalisation and the fact that states enter treaties with new obligations, SOEs’ performance ceased to be solely a domestic problem, increasingly so as state-owned multinational enterprises (SOMNEs) emerge. This article presents the results of research on Polish SOEs’ outward foreign direct investment (OFDI). It offers an overview of overseas activities of nine major Polish firms with a state stake and aims to contribute to the conceptual literature on foreign investments conducted by SOMNEs. We distinguish between FDI by SOMNEs as specific – privileged (facilitated) or discriminated (hampered) – investments subject to the home country’s state power and the host country’s state perception. 相似文献
The advertising and marketing literature have established that celebrity endorsements constitute an effective way to enhance attitudes toward brands and increase purchase intents. However, there are no relevant studies on digital influencers. This study addresses the research gap by examining the effect of digital influencers' attractiveness and the effect of the congruence between a digital influencer and a brand on consumer attitudes and purchase intentions. By applying structural equation modeling to a sample of 307 followers of digital influencers, a model was tested and group analysis was performed for two categories (“entertainment & video games” and “fashion & beauty”). The results show that both brand attitudes and purchase intentions are influenced by the digital influencer's attractiveness (which includes both likeability and familiarity) and by the congruence between the digital influencer and the brand. This study makes several contributions to both theory and practice, which are highlighted in this paper. 相似文献
This paper examines the determinants of intended electoral participation. We analyze attitudes to both referenda and voting
in national elections. Sample survey data are obtained from the Eurobarometer survey of transition countries in Central and
Eastern Europe. The empirical results suggest that intended electoral participation increases with age, income and education.
But attitudinal variables are also important and in particular confidence in the free market economy and satisfaction with
the general development of the country impact positively on intended electoral participation.

There is widespread understanding that intellectual capital (IC), consisting of the valuable knowledge resources of an organization, is a key enabler of innovation activities; however, little is known about the more specific contingencies impacting the relationship between IC and innovation. Thus, this article examines firm technology level and innovation type as contingency variables. It was argued that because high-tech and low-tech firms differ in terms of several knowledge characteristics (complexity, tacitness and pace of renovation), it is likely that their innovation performance is supported by different combinations of IC components. Furthermore, differences between product/service and managerial innovation could also lead to changes in the degree of relevance of various IC components. To test these contingency hypotheses, a survey dataset collected from 180 Spanish companies is analysed using structural equation modelling. The results demonstrate that both firm's technology level and type of innovation affect how IC influences innovation performance. The findings contribute to a knowledge-based perspective on innovation and pave the way for a more context-sensitive and contingency-mindful approach to understanding innovation and knowledge-based value creation. 相似文献
Today’s technology allows firms to collect, store and use different types of data. This has prompted a wide discussion on the effects of access to data on competition and consumer welfare. This discussion has also been present in the energy sector in which advanced technology has allowed for the collection of detailed energy consumption data. Prompted by this discussion on the energy sector, this paper studies an industry where two firms have access to the same technology and compete in prices, but one of them has access to better information about customers. The better informed firm obtains a customer contact advantage, whereas the uninformed firm can still offer a menu of prices without being able to pre-identify the customers. We show that the better informed firm is able to exclude the uninformed firm from the market. This result provides policy insights on the usefulness of considering data access models that can ensure non-discriminatory behaviour.
In this paper, we develop a R&D-based growth model with a pollution externality and a health production sector. We study how health-impairing pollution affects long term growth, and the effect of an emissions' reduction policy (tax). We show that a tighter environmental tax has positive effects on growth via two channels. On the one hand, it improves workers' health and, thereby, productivity; on the other hand, it induces a reallocation of resources towards R&D and, thereby, higher research intensity. The size of the growth effect of a tighter environmental tax, and the level of the optimal environmental tax, are both positively correlated with the weight individuals place on health relative to consumption. As for welfare, a tighter environmental tax brings about utility gains in the long run and, potentially, also in the short run. 相似文献
We consider a pure exchange economy with a finite set of types of agents which have incomplete and asymmetric information
on the states of nature. Our aim was to describe the equilibrium price formation and analyze how the lack of information may
affect the allocation of resources. To do so, we adapt to an asymmetric information scenario a variant of the Shapley–Shubik
game introduced by Dubey and Geanakoplos (J Math Econ 39:391–400, 2003 ). 相似文献
It is easy to understand why regions that produce very fine goods such as port wine tend to conceal technological and scientific inputs and praise the uniqueness of the terroir. This paper suggests that, during the last decades of the nineteenth century, viticulture in the Douro region of Portugal was as much a product of soil, local farming traditions, and individual entrepreneurship as it was of modern state science and national politics for agricultural improvement. the unprecedented public projects of building a railroad and fighting phylloxera permanently changed the land of port wine. Moreover, those engineering practices of rationalization, simplification, and standardization that were inscribed on Douro's landscape proved essential for the Portuguese experience of modernization and nation-building. 相似文献
