Since McCallum's (1995 McCallum, J. 1995. National borders matter: Canada-US regional trade patterns. American Economic Review, 85(3): 61523. [Web of Science ®] [Google Scholar]) finding of surprisingly high border effects on trade between the US and Canada, there have been a number of studies on other parts of the world, and improvements made to the gravity model to measure this effect accurately. This paper suggests some other modifications to the model, and applies it to a region of the world that presents a distinctly interesting case. Changes in border effects of formerly socialist countries in Central and East Europe, and countries in the former Soviet Union are analyzed during 1976–2002 at country and sectoral levels, and also with respect to blocs of countries. A discussion on cross-country variations in border effects follows the computations.  相似文献

Abstract

This paper explores the social dynamics by means of which market forces are enacted at the level of everyday consumption. In particular, it draws on Holt's (2002 Holt, D.B. 2002. Why do brands cause trouble? A dialectical theory of consumer culture and branding. Journal of Consumer Research, 29: 7090. [Crossref], [Web of Science ®] [Google Scholar]) notion that as ‘unruly bricoleurs’, consumers kick-start processes of market adjustment and innovation through improvising ways to negotiate the demands of daily life. In this way, consumers can become active players in realising new possibilities for identity construction and empowerment that involve the creative re-appropriation of marketer-based meaning. To investigate those issues, we turn to a virtual community in the empirical setting of car customisation. Over an eight-month period, an internet-based methodology generated textual observations of online posting activity on five internet newsgroups attracting those interested in the particular pursuit of car modification. Participants used those web-forums to share information, passions, and enthusiasms. Analysis shows that grounded aesthetics function as vehicles for creativity and the reworking of dominant market logics (Vargo & Lusch, 2004 Vargo, S.L. and Lusch, R.F. 2004. Evolving to a new dominant logic for marketing. Journal of Marketing, 68: 118. [Crossref], [Web of Science ®] [Google Scholar]). We conclude that online discussion threads offer valuable access to the emergent interplay of discursive resources in circulation among virtual communities and that this has implications for the conduct of environmental scanning. The paper illustrates how the discursive resource-base is nurtured, sustained, and transformed through various interpellations, including performing claims to prestige and self-defining distinctions, as well as constructing narratives of personal history and social dynamics.  相似文献

The internationalisation of the firm is a highly dynamic process, in which periods of investment and expansion intermingle with periods of divestment and retrenchment. Academic research to date has focused on identifying the reasons for and the processes of divestment. Empirical studies either evidence generic pressures or provide case studies of specific incidents. There few longitudinal studies of international divestment, consequently the dynamic interactions between host market, home market and firm level factors, and how the institutional context changes over time is underplayed. This paper seeks to rectify this gap in our understanding.We explore the rationale and evolving dynamics of European grocery retail divestment in East Asia over a thirty year period. Taking an inductive approach and drawing on analysis of contemporary narratives drawn from company documentation, trade journals, newsfeeds and market reports, three phases can be identified characterised by specific factors and combinations of factors which intersect to provide the key pressures and stimuli for divestment. We conclude that at different time periods, different internal and external contextual influences manifest themselves through different priorities within the firm’s strategy – marked by a switch from local (host) market, to regional, to global firm-centric considerations. Longitudinal analyses allow a greater recognition of this dynamic interplay of factors, and the changes in these relationships, and provides a more nuanced understanding of the international divestment process.  相似文献

组织变革前会有相关的非正式信息,这些信息影响员工对变革的认识。文章探索变革前消极非正式信息量对员工变革抵制意愿的影响,以及员工变革抵制意愿随时间推移的变化,信息频率与尽责性对员工变革抵制意愿变化的调节作用。基于159位员工调查数据的多层次线性增长模型分析表明:消极非正式信息量显著增加员工的变革抵制意愿,但这种抵制意愿随时间推移而显著衰减;消极非正式信息频率与尽责性对员工变革抵制意愿随时间衰减有三维调节作用:在低信息频率下,低尽责性员工的变革抵制意愿随时间衰减更快。研究结果对组织变革有一定理论和实践意义。  相似文献

Previous research suggests that attitudinal resistance to information that challenges a prior evaluation increases with the amount of information underlying the prior evaluation. We revisit this proposition in a context in which a set of important claims about a target brand are presented either alone—a lower amount of isolated information—or along with other favorable, but less important claims—a higher amount of embedded information. Results from two experiments show that when the challenge occurs immediately after the initial evaluation, a greater amount of embedded initial information does produce greater attitudinal resistance. However, when the challenge occurs after a delay, a lesser amount of isolated information produces greater attitudinal resistance. The findings qualify previous assumptions about the role of prior information in attitudinal resistance, and support a constructive view of judgment revision and attitudinal resistance.  相似文献

This article presents a framework for exploring salesperson(s) resistance to sharing market intelligence in emerging markets in Sub-Saharan Africa. The authors propose that resistance to sharing market intelligence with relevant others, including the firm, coworkers, intermediaries, and sales managers, is a function of various individual, leadership, and organizational (firm) factors. This framework helps researchers understand how and why resistance develops among salespeople. Moreover, implications from these findings are presented to assist practitioners who wish to persuade and encourage African salespeople to share market intelligence for the benefit of their firms.  相似文献

Fungicide resistance is a serious problem for agriculture today. This analysis provides additional insight into the strategic behavior of farmers when their fungicide use generates a negative intertemporal production externality in the form of fungicide resistance. We find that when farmers encounter this type of externality, they choose fungicide levels that exacerbate fungicide resistance. We examine a compensation mechanism in which a farmer reduces fungicide use in exchange for a transfer. This mechanism reduces fungicide use; however, misinformation about the severity of fungicide resistance generates distortions. We find that one-sided misinformation could lead a farmer to choose socially optimal fungicide levels, which makes the compensation mechanism less necessary. In addition, we show that when both farmers are misinformed, the mechanism could lead farmers to choose fungicide levels below the socially optimal level depending on their pessimistic beliefs about the severity of fungicide resistance.  相似文献
