Employment effects of business dynamics: Mice, Gazelles and Elephants   总被引:2,自引:0,他引:2  
Much of the theoretical work on industry dynamics focuses on the role of ‘noisy’ selection and incomplete information on firm entry and survival. We extend this research by looking at the impact of firm heterogeneity on employment effects for 320 U.S. Metropolitan Statistical Areas (MSA). We find that only start-ups with greater than 20 and less than 500 employees have persistent employment effects over time and only in large diversified metropolitan regions. Therefore, both the type of entry (Gazelles) and the characteristics of the region are important for employment growth.

Based on institutional theory and risk perspectives, this study examines how the entrepreneurial orientation of firms as determined by national cultural factors is related to the internationalization of small- and medium-sized enterprises (SMEs) from emerging and developing countries. We also suggest that institutional improvements can have a moderating effect on the relationship between culture and internationalization. We develop a unique measure of internationalization and test it on a sample of 7,212 SMEs from 36 developing countries using a multilevel linear hierarchical model that allows us to examine both firm- and country-level effects. We find that developed institutions support the internationalization of SMEs from more masculine and individualistic cultures.  相似文献

Geoscientists are faced with a number of complexities that represent obstacles to the development of realistic simulation of deep earth processes. Realistic 4D thermo-mechanical simulation using software packages like Underworld and Gale, when combined appropriately with geoscientific expertise, can lead to novel insights into the deformation of geological structures at a wide range of time and spatial scales. The challenge for end-user geoscientists lies in applying their knowledge within the framework of the software’s input specification, including initial, internal, and boundary conditions and output visualization parameters. We have built a Graphical User Interface (GUI) to remove many of the difficulties related to editing the Extensible Markup Language (XML) encoded input files of Underworld/Gale geomodels and therefore, to greatly broaden the user base of these software packages. By helping Underworld/Gale to meet a large audience, we provide a tool to the geoscience community that helps to move from untested conceptual models to physically valid, properly scaled modelling. Furthermore, the UnderworldGUI offers a mechanism for storing and retrieving experimental models in a centralised database, thus providing the geoscience community with a means to share the outcomes of its experimental research. Further details of the UnderworldGUI are available at the web site http://www.wiki.vislab.usyd.edu.au/moinwiki/UnderworldGUI.  相似文献

In this Point–Counterpoint article we argue that institutional scholarship has become overly concerned with explaining institutions and institutional processes, notably at the level of the organization field, rather than with using them to explain and understand organizations. Especially missing is an attempt to gain a coherent, holistic account of how organizations are structured and managed. We also argue that when institutional theory does give attention to organizations it inappropriately treats them as though they are the same, or at least as though any differences are irrelevant for purposes of theory. We propose a return to the study of organizations with an emphasis upon comparative analysis, and suggest the institutional logics perspective as an appropriate means for doing so.  相似文献

This study provides insight into the dominant methodological practices that have shaped the field of negotiation over the past four decades and sheds light on possible gaps and trade-offs. We content analyzed 941 peer-reviewed negotiation articles (published between 1965 and 2004) and identified the most important methodological trends over time. The results reveal significant changes in reliability, validity, and triangulation issues. In addition, the rise of multivariate statistics and multiple data sources displays positive evolution towards more sophisticated methodologies. Despite these positive evolutions, we want to encourage current and future researchers to conduct more longitudinal and qualitative research to further advance our knowledge on negotiation.  相似文献

Three entrepreneurial case studies in Canada show that changes in the environment??such as changes in customers?? needs and changes in competitive products??are the major sources of opportunities. To recognize and exploit these opportunities, the firm needs entrepreneurial capabilities. At the same time, to gain long-run competitive advantage, the firm needs dynamic capabilities. The case findings show that entrepreneurial capabilities have circular and iterative relationship with dynamic capabilities??each reinforces the other. The more often the iteration takes place, the stronger entrepreneurial capabilities and dynamic capabilities are. Further, the study builds on the extant literature and develops a new method to capture dynamic capabilities through capturing changes in ordinary capabilities.  相似文献

Peasant households in Southeast Asia and elsewhere live on the margin of subsistence. Their survival strategies make them technological conservatives and weavers of reciprocal webs of social obligation and dependence. James C. Scott has argued that the fabric of this “moral economy” both guarantees subsistence for the peasants and forms the touchstone on which their judgements of social justice are tested. When those who should offer succor withdraw it, peasants are outraged and from their anger springs peasant rebellion. Two South Asian peasant rebellions of the 1940s (Telengana and Tebhaga) fail to support Scott's account and raise major questions about his historical method. Two others case studies focused on the early years of colonial contact (the Padri Wars and the capitalist transformation of the Kaveri delta) lead the authors to question sharply the existence of a “moral economy of the peasant” and to suggest that Scott has inadvertently presented a landlord's view of peasant society.  相似文献

Stability and instability in oligopoly   总被引:1,自引:0,他引:1  
For regular oligopolies (both homogeneous and heterogeneous) the (local) Cournot-Nash equilibria are the (non-degenerate) critical points of a Morse-Smale vector field, defined on the feasible region of non-negative prices and outputs. When at the boundary of this feasible region this vector field points inwards, it follows from the Morse inequalities that there is at least one stable equilibrium. When there is a unique, non-stable, interior equilibrium, necessarily the vector field points outwards somewhere along the boundary of the feasible region. This raises to a stable boundary equilibrium.  相似文献
