abstract    Business groups are the primary form of managing large business organizations outside North America. This paper provides a systematic and integrative framework for understanding business groups. We argue that existing theoretical perspectives of business groups pay attention to four critical external contexts, each of which draws from a specific theoretical perspective: market conditions (transaction cost theory), social relationships (relational perspective), political factors (political economy perspective), and external monitoring mechanisms (agency theory). Business groups adapt to these external forces by deploying various internal mechanisms along two key dimensions: one focuses on the distinctive roles of the group affiliates (horizontal connectedness) and the other focuses on coupling and order between the parent firm and its affiliates (vertical linkages). Based on these two dimensions, a typology of business group forms is developed: network (N-form), club (C-form), holding (H-form), and multidivisional (M-form). Utilizing this model we provide research questions which facilitate an improved future research agenda.  相似文献

Abstract
Russia has recently embarked on a dramatic program of privatisation as part of the process of shock therapy which aims to convert the command economy to a market economy. This program has been undertaken in the absence of a well-developed set of institutions needed for the proper functioning of a market economy. These institutions include a legal system, a related system of property rights, a credit system, a system of commercial banks, classified advertising, an accounting system and others including a sound currency and a social safety net. In the absence of these institutions the incentives facing agents in economic transactions have been perverted. This has led to criminalisation of the economy, dramatic falls in production, loss of confidence in all aspects of commerce, and political instability. The recent Russian experience of privatisation has important lessons for other economies in transition, for developing economies and for economic theory.  相似文献

Mackay Whitsunday Safe Communities (MWSC) was developed using a capacity building model that consciously attempted to design sustainability into the network. Our aim was to quantify the flow of resources used by MWSC to implement and sustain its injury control activities. Resource exchange among network members was quantified and analysed using social network analysis. In 2004, MWSC accessed an estimated 6.5 full-time staff equivalents and $0.9 million. However, these resources were largely accessed externally. The linking relationships that connected MWSC to its external support network, more than half of which were maintained by six broker network facilitators, were the critical social asset used to access resources and sustain network productivity. The sustainability of this network and arguably similar safety promotion networks is vulnerable to the changing priorities of external sponsoring agents and highly dependent on its leaders who facilitated access to the resources it required to remain productive.  相似文献

In this engrossing study of management consulting, ChristopherMcKenna seeks to understand the prominence of consulting withinAmerican business. Focusing on a small set of elite consultingfirms, but frequently discussing others, McKenna argues thatthe legitimacy and knowledge sold by consultants to their clientswere rooted in the growing complexity and internationalizationof the American economy (the forces conventionally invoked toexplain consulting's rise), as well as changes in federal regulationsin the 1930s, 1950s, and 1980s.  相似文献

Priorities for prevention activities and planning for services depend on comprehensive knowledge of the distribution of the injury-related burden in the community. The aim of this systematic review was to quantify the effect of being injured, compared with not being injured, on long-term mortality in working age adults. Cohort studies were selected that were population-based, measured mortality post-discharge from inpatient treatment, included a non-injured comparison group and related to working-age adults. Data synthesis was in tabular and text form with a meta-analysis not being possible because of the heterogeneity between studies. Eleven studies met the inclusion criteria. All studies found an overall positive association between injury and increased mortality. While the greatest excess mortality was evident during the initial period post-injury, increased mortality was shown in some studies to persist for up to 40 years after injury. Due to the limited number of injury types studied and heterogeneity between studies, there is insufficient published evidence on which to calculate population estimates of long-term mortality, where injury is a component cause. The review does suggest there is considerable excess mortality following injury that is not accounted for in current methods of quantifying injury burden, and is not used to assess quality and effectiveness of trauma care.  相似文献
