Investment, uncertainty and irreversibility   总被引:1,自引:0,他引:1  
This paper investigates the irreversibility of investments and the impact this has on the nature of the relationship between investment and uncertainty. The empirical analysis uses firm‐level data and is based on a survey of 210 rice‐milling firms in the Mekong River Delta in Vietnam, which was carried out during the year 2000. We show that uncertainty reduces investment of rice millers in the presence of irreversibility, as is predicted by the real options approach to investment. We do not find evidence that the negative association between uncertainty and investment is influenced by the degree of irreversibility.  相似文献

We show how technological flexibility choices and equilibrium configurations (both simultaneous and sequential duopoly) depend on six industry characteristics. Low market volatility combined with intermediate market size favors inflexible technologies; large values of either volatility or size favor flexible technologies; low or intermediate values of both favor the coexistence of flexible and inflexible technologies. The possibility of a flexibility trap exists in industries of low volatility and intermediate size. Entry prevention can sometimes be achieved by inflexible technologies or flexible technologies, depending on the industry characteristics.  相似文献

This paper describes the Flemish customer contact centre for government information (‘the Flemish Infoline’) as an example of marketing in the public sector. First it defines the term ‘customer contact centre’ and describes the objectives and main characteristics of the Flemish Infoline. It then identifies the three reasons for setting up the Flemish Infoline in 1999: the complicated Belgian institutional landscape; the unprofessional telephone traffic handling and service; and the lack of knowledge about citizens' information needs. Finally, the paper applies Kotler's 4 Ps concept to the case, and puts the relevant stages from Lees‐Marsh‐ment's political marketing orientations into one integrated scheme in order to understand the functioning of the Flemish Infoline. Based on the literature and on an in‐depth interview with the project head of the Flemish Infoline, the authors demonstrate that marketing techniques can be used in contact centres for public information, but they also illustrate some important differences from those in the forprofit sector, such as the available amount of customers' personal data, the level of call operators' skills and the degree of heterogeneity of the questions. Further research on information needs and contact centres, and providing one ‘umbrella’ contact centre for government information in Belgium are recommended.

To establish the predictive validity of ethnic identification measures, respondents in the Montreal Urban Community were surveyed and measured on a variety of ethnic dimensions. The data was then fed to a clustering algorithm. Two-group clustering assignments were then compared to traditional taxonomic measures. It is shown that some measures do an excellent job in classifying respondents, while others, which are commonly used in practice, do not fare as well.  相似文献

城域网是与局域网和广域网相对应的计算机网络的概念,数据通信和电信技术的发展赋予城域网新的内涵,将城域网的概念延伸到整个通信网络,泛指在城市及其郊区范围内提供多种业务的所有网络。城域网覆盖大约2公里到150公里的范围,是城市中作为局域网互连的高速网络,它以宽带光传输为开放平台。各个城市的城域网最终将透过更大范围的广域网络骨干相互衔接,最终形成一个全国或全世界规模的无所不在的网络。  相似文献

The Impact of the 9/11 Events on the American and French Stock Markets   总被引:1,自引:0,他引:1  
Markets reacted strongly to the World Trade Center attacks both in Europe and in the United States. The extent of this crisis was difficult to assess at the time, underlining the need for a specific tool to measure the magnitude of financial crises. A first measure was recently proposed and applied to the foreign exchange market by Zumbach et al. (2000a,b ). Their measure relies on an analogy with geophysics; the related index of market shocks (IMS) that we propose here is also the counterpart of the Richter scale used for earthquakes. We apply this measure on the French and the American stock markets to put large market events into perspective. The crisis triggered by the September attacks was actually the worst since 1987, and the ninth worst when compared to major historical ones.  相似文献

Announcements of syndication loans increase borrowers' shareholder wealth if they are revolving credit agreements but not if they are term loans. Share price responses to revolving credit announcements are positive and significant, whereas the wealth effect for term loans is negative and significant. The results show that announcements from both the financial press and commercial information providers can affect borrower share price reaction. Overall, single syndication announcements appear to be more newsworthy than multiple announcements reported in the financial press, and we find evidence of information leakage, post‐announcement drift, or both.  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
