It seems that everybody wants to know which companies are the most successful. To help throw light on the issue, and to do so more reliably than the plethora of league tables and charts produced by most business magazines, the London Business School have teamed up with The Economist to compile an assessment of the top performers of the 1980's.  相似文献

Infrastructural and societal changes intertwine in multiple ways. This makes the societal implications of infrastructural projects difficult to assess and anticipate. Yet in present day network societies this task is particularly urgent. This paper first identifies two positions that tend to monopolize and deadlock debates. Next it examines two decades of research in the Large Technical System (LTS) research field for alternative approaches to this issue, before finally suggesting distinguishing between the four increasingly indirect moments of (co-) construction of infrastructures and societies. These may be related causally, but also add their own moments of contingency, agency, and choice.  相似文献

Many firms are experimenting with how to standardize new technologies. They may use proprietary technologies for their products and services, and let them compete in the market selection. Alternatively, they can cooperate to jointly set a standard and experiment with combinations of market process and cooperation. If firms let the market decide, they can compete with technologies and need not invest time and effort in hammering out a standard. If they do incur the costs of negotiated standardization, they may enable end users to realize the benefits of standards. A hybrid standardization process combines the advantages of both market selection and negotiated decision making. This paper presents a contingency framework to identify conditions that will affect the preferred standardization process for vendors who introduce new technologies. A major contingency that this paper points to is the systemic nature of technologies in information and communication technology industries. The more systemic the technology is (in a way to be clarified), the less likely that firms will establish a hybrid standardization process. One advantage of decomposing technology systems in smaller components (modules) is that this approach enables firms to combine market selection with negotiated selection of standards.  相似文献

This paper investigates whether governments can change market structures through interventions. We study the effects of four political events over the life cycle of the market for daily newspapers in the Netherlands. We find that policy measures meant to lower entry barriers in an expanding industry created new entry and increased survival chances for potential entrants and incumbent newspapers. Exit barrier enhancing policies to reduce concentration tendencies have not been successful.  相似文献

A commercial environment is clearly good for contemporary popular music but can ‘art’ music flourish in such an environment? In the past art music has prospered on a commercial basis and there are advantages in exposing art to commerce. For example, commercial patronage is likely to be more diverse and allow more room for experimentation than a single patron or subsidising body. Moreover, commerce encourages two‐way communication between artist and audience.  相似文献

Abstract State sponsored employment agencies are an important source of job matching in Britain. This study tracks Jobcentre use in Britain over the previous decade and the effectiveness of Jobcentre use in securing entry into employment for those who utilise its services. Amongst the unemployed, use of Jobcentres is highly counter-cyclical. This can be attributed principally to the changing composition of the stock over the economic cycle. In good times, there are relatively more short duration, voluntary quits in the stock, who tend to rely on Jobcentres least. Jobcentres are found to have a significant positive effect on the job entry rates of its clients. The greatest beneficial impact is amongst those, the low skilled and the long term unemployed with the lowest exit rates from unemployment.  相似文献

This paper discusses the impact of a redistribution of current income from the White to the Black population on the distribution of sectoral output, and total employment by means of a semi‐closed input‐output model.

The results show that a redistribution of current income towards Black households — which no doubt will have positive social and political repercussions — has a non‐negative effect on GDP and a definite positive effect on the performance of sectors with a high private consumption expenditure component, as well as on total employment.  相似文献
