The purpose of this paper is to empirically explore two dimensions of the firm hierarchy of international market-specific linkages, using data on Swedish manufacturing firms from 1997 to 2007. First, we investigate the productivity ordering with respect to three international linkages; importing, exporting and investing abroad. Second, we explore whether differences in the productivity ordering across industries correlates with industry and country characteristics. Our findings support a general productivity hierarchy from importing to exporting and from exporting to investing abroad, as well as from a low to a high number of linkages (measuring the complexity of firms’ international linkages). However, an industry-by-industry examination shows that the hierarchical structure is only generally upheld when it comes to the number of international linkages, while the ordering of import, export and investment linkages does not exhibit the same regularity across industries. Extending the analysis, we find that the lack of a hierarchical structure is more likely in industries focusing on larger and less distant markets.  相似文献

It is hard to assess the coordinated effect of mergers in solid and convincing fashion, in part because economic theory deals mainly with the sustainability of tacit collusion and generally does not explore the conditions that foster collusion in the first place. Also the most popular schemes of collusion (Joint profit maximization and Nash Bargaining) proposed by the economic literature seem at odds with the evidence recorded on cartels and with the practical attitude of entrepreneurs. In this scenario the recent version of the Horizontal Merger Guidelines contained the interesting suggestion to pay attention to the process - parallel behaviour – which leads to collusive equilibria. Working on the same intuition we propose an approach based on the idea that firms can always find a feasible collusive agreement, for every possible value of the factor which discounts future profits. Assuming that in order to collude, firms demand the fair sharing of collusive gains, we exploit the egalitarian property of grim trigger strategies when all incentive compatibility constraints are binding. This approach suggests using three indicators to determine whether and how a merger affects the probability of collusion. An application of this approach to a real-world case (the AT&T/T-Mobile merger) is provided.  相似文献

Within the growing body of Chinese entrepreneurship literature, guanxi is increasingly recognized as an important indigenous Chinese business practice with important implications for firm performance and success. Guanxi is defined as relationship or connection. China’s continued economic growth and forecasts of it becoming one of the world’s largest consumer markets present multinational corporations and foreign entrepreneurs alike with unprecedented economic opportunities. Thus, greater insight is required into how foreign entrepreneurs, as outsiders, establish and develop close guanxi relationships. Conceptualizing guanxi as a dynamic process, this paper explores the underlying interactions and processes foreign entrepreneurs engage in to establish and build a strong emotional connection and trust with their closest guanxi partner. Using an exploratory single case study approach, data from 15 foreign entrepreneurs operating legally registered small- and medium-size enterprises (SMEs) in Shanghai was collected and analyzed. In addition, self-administered structured questionnaires that utilize the McAllister trust scale were used to measure 20 foreign entrepreneurs’ levels of cognitive and affective trust toward their closest guanxi partner. Overall, the findings of the study provide an in-depth understanding of the complex interplay and functioning of third-party and anticipatory bases. In so doing, the study’s outsider perspective addresses a critical gap in the literature that yields initial yet important insights that contribute to a better understanding and appreciation of the inherent nuances and differences in relationship-building processes in cross-cultural settings. Furthermore, these findings bring to the fore the need to consider the ways in which this indigenous Chinese business practice may be evolving in the face of increasing internationalization.  相似文献

Emergence of the Internet as a new distribution channel has led to increasing attention by researchers to dual-channel supply chain in recent years. In this paper, pricing and ordering decisions are investigated on a dual-channel supply chain which consists of monopolistic manufacturer and duopolistic retailers. The market is assumed to be controlled by the manufacturer. Thus, the manufacturer becomes leader and the two retailers act as followers. Due to establishing this new structure, different game-theoretic models including Bertrand, Collusion, and Stackelberg are developed to analyze pricing strategies under the various interactions between the two retailers. Then, the equilibrium decisions are compared under the considered scenarios and valuable managerial insights are presented. We found that the various games do not have any effects on the manufacturer’s responses. The retail prices given by the Collusion game are higher than by the other games. In the Collusion model, demands in the retail channel are lower than in the other games. Moreover, the manufacturer and retailers receive respectively the lowest and the highest profits under the Collusion game.  相似文献

数字普惠金融与实体经济之间的关系受到学界广泛关注,但其究竟是普惠的数字红利还是金融领域的数字鸿沟,这是数字普惠金融快速发展中亟需回答的重要理论与现实问题。文章通过匹配宏观统计数据和微观调查数据,实证研究了数字普惠金融的发展对收入不平等的影响,并从创业效应这一渠道进行了机制分析。研究发现:数字普惠金融的发展总体上改善了收入不平等状况,而数字普惠金融的创业效应是影响收入不平等的重要渠道之一。进一步的中介效应分析表明,数字普惠金融的创业效应对收入不平等的影响存在异质性:数字普惠金融通过促进生存型创业从而改善了收入不平等,而数字普惠金融对机会型创业的促进却在一定程度上扩大了收入不平等。文章的研究结论对于理解数字普惠金融发展的正外部性以及如何缓解收入不平等提供了新的视角。  相似文献

Despite being generally well studied, emotional stability (ES) has not yet been widely accepted as a satisfactory and solidly valid theoretical construct. Without a clearly defined and validated construct, it is difficult to infer what ES means for the behavior and decisions of individuals as well as the performance of groups and organizations. Based on self-organization theory, this study infers a two dimensional construct for ES (threshold and recovery) under the framework of dynamic change and complexity. Two studies were conducted in China to develop and examine the construct of ES in an organizational context. The psychometric examination indicated that the newly developed construct of ES has discriminant and convergent validity with respect to different though related constructs such as the Big Five personality model and emotional intelligence (EI). It also demonstrates incremental validity in predicting group leadership, job satisfaction, job self-efficacy, and commitment. The findings also demonstrate that ES moderates the relationship between individual commitment and group relationship conflict. The results indicate that self-ratings effectively reflect the theoretical construct, whereas peer ratings and supervisor ratings create different biases. Additional theory, empirical, and methodological contributions are also discussed.  相似文献

The literature on socioeconomic status and health suggests that those in higher positions have better health, and those in lower positions have worse health. There is little evidence of an SES gradient in non-industrialized countries, however, and it is uncertain whether the health gradient established in many Western countries would apply in developing countries. In this study, the authors examine patterns in health outcomes by caste and religion in India, a developing country. Results from a nationally representative sample, the Indian Human Development Survey, suggest that while high SES social groups report less communicable disease, they report a higher prevalence of chronic diseases than low SES groups. This study demonstrates the need to examine diseases of affluence among high SES groups in developing countries while also identifying the particular health concerns that are prevalent among low SES groups.  相似文献

The long-term forecasting of the development of the Irkutsk region by economic sectors is considered. The evaluations of the structural changes and the interregional relationships by the variants of the potential trends of development of the economy of Siberia and Russia in a whole are presented. The forecast is made by the production output data, which are the basis of the target growth of the final consumption.  相似文献

Since the start of EMU (Economic and Monetary Union), the euro area, and more broadly the global economy, experienced an unprecedented credit boom. The expansion of credit was particularly strong in Greece, Ireland, Portugal and Cyprus and all of them subsequently needed official financial support. In each of the four programmes, financial assistance has been provided and promised against the commitment of each country to fulfil certain economic policy conditions contained in the macroeconomic adjustment programme. In general, a macroeconomic adjustment is a process driven by policies but also by changes in private spending behaviour (consumption, imports, investment) and improvement in competitiveness that countries are required to undertake after a large shock. In the case of the four countries, the shock emerged as a consequence of an excessive accumulation of imbalances in different parts of the economy: in the public sector in Greece, in the housing and banking sectors in Ireland, external imbalances in Portugal and in the banking sector in Cyprus. The paper looks at the feasibility of the fiscal adjustment comparing the macroeconomic conditions in the four countries and emphasising the role of the fiscal multipliers in the process. It also assesses the fall in the output in a comparative framework, stressing the role played by the different components of demand either in amplifying the effect of the fiscal consolidation or in offsetting it. In addition, it considers formulation of the programmes as well as their implementation with most attention devoted to reforms aiming at improving competitiveness, growth and employment in the framework of a cross-country approach.  相似文献
