This paper examines whether a power and leverage perspective, successfully applied to analyse extended buyer-supplier relationships in a western context, can be used to analyse business relationships in China. A single embedded case study is presented in this paper and a power and leverage approach is used to analyse business relationships. The power and leverage perspective is applicable for investigating buyer-supplier relationships in a Chinese cultural context. However, in this context using power as coercion is an extremely counterproductive relationship management strategy, which can draw both buyers and suppliers in to a "no-win" or negative sum situation. The findings are based upon a single case, which makes drawing generalisable conclusions more difficult. In addition, although every effort was made to limit the subjectivity of the power and relationship analysis, researcher interpretation of the data was required. In the Chinese business context, it may not be advisable to manage any relationships in an arms-length manner. Chinese business networks are centred on less explicit or formal power relationships and therefore companies that have learnt the rules of the game of exchange in the west need to modify their approach in China. This work extends the understanding of buyer-supplier relationships and provides additional empirical evidence validating a power and leverage perspective. In addition, the paper provides the first assessment of whether this approach can be used in a non-western context without significant modification.  相似文献

Abstract

Numerous outdoor recreation forecasting studies have included household characteristics as well as aspects of the recreation facilities and accessibility. Only a few studies, however, have included in the prediction equation any measure of the effects of urban milieu on behavior. Four commonly cited surrogates of urban milieu are used to cluster the cities of Illinois into three relatively homogeneous groups of environments. Regression analyses are then undertaken using individual household data, aspects of the recreation facilities patronized by the households, participation, and distance and travel time estimates. Comparisons of the regression analyses indicate that, as a concept, milieu is an important predictor of both the volume of recreation participation and salient features of recreation facilities.  相似文献

We present a test to determine whether variances of time series are constant over time. The test statistic is a suitably standardized maximum of cumulative first and second moments. We apply the test to time series of various assets and find that the test performs well in applications. Moreover, we propose a portfolio strategy based on our test which hedges against potential financial crises and show that it works in practice.  相似文献

The construction of territorial sovereignty is key to conceptions of modern states. Yet after the Partition of India and Pakistan in 1947, when both became independent from Britain, the precise nature of India’s relationship to Pakistan was open to some question. Was Pakistan a foreign country? Was India’s relationship to it international? This article uses the example of a dispute over water resources in the Indus Basin to highlight the process through which Indian officials in New Delhi’s External Affairs and Law ministries came to define Pakistan as constitutionally, as well as geographically, “outside” India between 1948 and 1951. Yet while Indian policy makers manoeuvred into an aggressive stance against Pakistan, both countries’ membership of the British Commonwealth implied an international relationship blurring the formal distinction between “domestic” and “foreign”. Negotiating the contradictions between Commonwealth rules and the desire to assert sovereignty over territory and resources, I argue, made Indian sovereignty contingent on circumstance.  相似文献

The aim of this study is twofold. First, the determinants of economic growth are studied among a wide set of potential variables for the Spanish provinces (NUTS3). Among others, various types of private, public and human capital in the group of growth factors are included. Also, it is analysed whether Spanish provinces have converged in economic terms in recent decades. The second objective is to obtain cross-section and panel data parameter estimates that are robust to model specification. For this purpose, a Bayesian Model Averaging (BMA) approach is used. Bayesian methodology constructs parameter estimates as a weighted average of linear regression estimates for every possible combination of included variables. The weight of each regression estimate is given by the posterior probability of each model.  相似文献

This paper analyzes factors explaining supply and demand of local public transportation. Together with variables related to traditional economic factors and mobility, we consider variables reflecting institutional characteristics and geographical patterns. Being a political capital increases supply and demand of local public transportation, inequality is associated with higher supply, and contracting out reduces supply. Furthermore, our regional analysis allows us capturing the effect of geographical characteristics and different traditions of government intervention. In all, we provide first evidence on the role played by institutional and regional characteristics useful to achieve a better understanding of local public transportation supply and demand.  相似文献

In this article, we suggest that one of the unexplored paths toward collaboration between firms and civil society organizations starts with confrontation or potential conflict, and that the transition toward collaboration can be further understood if one focuses on triadic relationships rather than dyadic ones. We analyze the presence of third parties and their different roles to explain how collaboration is facilitated. The article aims at bringing together the bodies of research on business–civil society confrontation and on business–civil society collaboration. It offers a comparative analysis of four case studies, and proposes a typology of third parties composed of facilitating allies, participating allies, mediators, and solution seekers. We conclude with some implications for further research as well as for practice.  相似文献

We examine executive stock option exercises around a sample of merger and acquisition announcements between 1996 and 2006, focusing on a subset we identify as potentially informed. For stock‐financed acquisitions, we find a surge in informed exercises by acquirer insiders in the year leading up to the acquisition announcement, but target insiders display no similar increase. We find the market reaction upon the announcement for acquirers is negatively related to extreme early exercises and find some evidence of long‐run underperformance. Overall, our evidence indicates that insiders knowingly bid for firms when they personally believe their own firm is overvalued.  相似文献
