培育和发展具有核心竞争力的大公司和大企业集团

为了增强中国经济实力和对“入世”后面对的激烈竞争，必须发展大公司和大企业集团。从目前情况看，中国的大公司和大企业集团的核心竞争力还很弱，在技术创新能力，多样化经营能力，适应市场能力和赢利能力等方面都与发达国家的大企业存在很大差距，我们必须从体制，机制，技术创新，增加人力资本，改善外部环境等方面多做工作，促进大公司和大企业集团核心竞争力的提高。     

Complementarity, coordination and compatibility: The role of fixed costs in the economics of systems

We analyze industry equilibrium and incentive to compatibility when goods produced by different producers generate utility only when consumed as component parts of a system. We assume the presence of two systems, each composed of some basic component and a set of differentiated complementary products. The combination of complementarity between the two components of the system and of fixed costs in the production of the complementary product results in a form of network effect. We focus on the role played by the size of the fixed costs in the production of the complementary products in determining the size of this system effect and, by this means, the structure and types of equilibria that may be observed: monopolistic or duopolistic, symmetric or asymmetric. We also highlight the consequence of the same fixed costs for the private and social incentives to render the systems compatible.     

Do converters facilitate the transition to a new incompatible technology? A dynamic analysis of converters

This paper analyzes the process of transition in standards between incompatible technologies when converters are available. Contrary to a common presumption that converters facilitate the transition from an old technology to an otherwise incompatible new technology, I find circumstances in which the possibility of transition is blockaded by the existence of converters. In the welfare analysis of converters, a distinction is made between ex ante and ex post efficiency effects. Finally, I also analyze the equilibrium behavior in the provision of converters and compare it to the socially optimal outcome.

MNE competence‐creating subsidiary mandates

The determinants of R&D intensity differ between subsidiaries in a multinational enterprise (MNE). Previous literature suggests that whether a subsidiary achieves a competence‐creating output mandate depends on the qualities of its location. R&D strategies in competence‐creating subsidiaries are supply‐driven while those in purely competence‐exploiting subsidiaries are demand‐driven. Using data on U.K. subsidiaries of non‐U.K. MNEs, we find that the level of subsidiary R&D depends on MNE group‐level and subsidiary‐level characteristics as well as locational factors. The R&D of mandated subsidiaries rises with acquisition, but for non‐mandated subsidiaries R&D falls upon acquisition. MNEs that grow through acquisition have more inter‐subsidiary R&D diversity.

Social networks in the global banking sector

We show that banks with shared social connections partner more often in the global syndicated loan market and that central banks in the network play dominant roles in various interbank transactions, indicating that social connections facilitate business connections. However, more centralized banks in the network also contribute significantly to the global systemic risk. Moreover, we find the soft information generated by social networks is particularly valuable when potential partners operate under different accounting and regulatory standards. Finally, we show that the recent banking crisis significantly limited the positive soft information effects of social networks in the global banking system.     

An application of network analysis on tourist attractions: The case of Xinjiang,China

This study constitutes a novel application of network analysis to explore the underlying mechanisms of tourist attraction network informed by tourist flows. Using survey data collected from a sample of 456 tourists visiting Xinjiang, China, the study applies the Quadratic Assignment Procedure (QAP) to test the relationships between region proximity, grade proximity, and tenure proximity, and the attraction network determined by tourists' free choice movements. Results show that while region proximity and tenure proximity among major attractions in a destination were positively related to attraction network, grade proximity was negatively related to the attraction network, indicating that same grade attractions were mostly competing with one another for tourists. The study contributes to the methodological development of social network analysis in tourism and advances understanding of demand-driven network relationships among tourist attractions in a destination. Destination management implications are discussed.     

The influence of restaurant co-workers’ perceived warmth and competence on employees’ turnover intentions: The mediating role of job attitudes

The current study examines the influence of co-workers’ perceived warmth and competence on employees’ job satisfaction, organizational commitment, and turnover intentions in a casual dining restaurant setting. The warmth and competence dimensions represent two fundamental social dimensions that people often use to evaluate other individuals or groups. The current findings determined that co-workers’ perceived warmth and competence had significant effects on employees’ job satisfaction, which in turn improved their organizational commitment.Furthermore, job satisfaction and organizational commitment mediated the relationships between co-workers’ perceived warmth and competence and employees’ turnover intentions. Theoretical and managerial implications are discussed.     

Contagion risk in the interbank market: a probabilistic approach to cope with incomplete structural information

One lesson of the financial crisis erupting in 2008 has been that domino effects constitute a serious threat to the stability of the financial sector, i.e. the failure of one node in the interbank network might entail the danger of contagion to large parts of the entire system. How important this effect is, depends on the exact topology of the network on which the supervisory authorities have typically very incomplete knowledge. In order to explore the extent of contagion effects and to analyse the effectiveness of macroprudential measures to contain such effects, a reconstruction of the quantitative features of the empirical network would be needed. We propose a probabilistic approach to such a reconstruction: we propose to combine some important known quantities (like the size of the banks) with a realistic stochastic representation of the remaining structural elements. Our approach allows us to evaluate relevant measures for the contagion risk after default of one unit (i.e. the number of expected subsequent defaults, or their probabilities). For some quantities we are able to derive closed form solutions, others can be obtained via computational mean-field approximations.
