South Africa's first build‐own‐operate‐transfer (BOOT) project for municipal services was signed in late December 1998 by the city of Durban and a private project company associated with French conglomerate Vivendi. The project will treat waste water for sale to industrial customers who would otherwise use more expensive potable water in their manufacturing processes. The project structure, with its multiple contracts and supporting agreements, guarantees and complex shareholding relationships, represents a sophisticated analytical challenge for lenders, whose financing will ultimately be at risk in the deal. Development finance institutions, such as the Development Bank of Southern Africa (DBSA), must review such projects in even greater detail because of their mandate to promote sustainable infrastructure development in the region. This article presents the DBSA ‘s analytical perspective on the Durban BOOT project in an effort to capture the complex, innovative and strongly developmental character of what, for South Africa, is a ground‐breaking public‐private partnership project.  相似文献

The aim of this study was to investigate how perceptions of job insecurity and fairness associate with individual well-being (job satisfaction and general health) and organizational attitudes (organizational commitment and turnover intention), under the condition that the psychological contract as perceived by the employee includes a promise on job security, or not. More specifically, we suggest that (H1) job insecurity is negatively related to individual well-being and organizational commitment and positively related to turnover intentions when job security is expected as part of the psychological contract, (H2) that job insecurity is negatively related to fairness perceptions when job security is expected as part of the psychological contract, (H3) that fairness associates positively with individual well-being and organizational commitment and negatively with turnover intentions and (H4) that the association between job insecurity, individual well-being and organizational outcomes is mediated by fairness under the condition that job security is expected as part of the psychological contract. Thus, we propose a model of mediated moderation. Results based on a sample of Belgian employees (N = 559) supported our hypotheses for organizational outcomes. For individual well-being, the mediation framework was not conditional upon a perceived promise of job security as part of the psychological contract. We conclude that employees' perceptions of job insecurity and fairness are important factors in employees' well-being and their attitudes towards the organization. More importantly, these perceptions can in part be shaped by organizational agents such as managers and supervisors. Additionally, the active utilization of the psychological contract in management strategies seems to have favourable results for the fostering of pro-organizational attitudes among employees.  相似文献

We consider a continuous-time stochastic optimization problem with infinite horizon, linear dynamics, and cone constraints which includes as a particular case portfolio selection problems under transaction costs for models of stock and currency markets. Using an appropriate geometric formalism we show that the Bellman function is the unique viscosity solution of a HJB equation.Mathematics Subject Classification (1991): 60G44JEL Classification: G13, G11This research was done at Munich University of Technology supported by a Mercator Guest Professorship of the German Science Foundation (Deutsche Forschungsgemeinschaft). The authors also express their thanks to Mark Davis, Steve Shreve, and Michael Taksar for useful discussions concerning the principle of dynamic programming.  相似文献

The Albanian health care system is currently in a period of deep transformation as well as the country is reflecting the future reforms after the turbulent development of the most recent years. The admission of Albania among future members of the European Union requires also an innovation in the health care system in order to build a model more compliant with the European performance and standards. These innovations are required also in the managerial approach to the health care and in its financing system. The aim of this paper is to analyze the actual financing model of the Albanian health care sector while highlighting the possible future managerial development. First of all, this article presents a history review of the Albanian health-care system, analyzing the current governance model. The goal of this approach is to describe the starting point of the reform paths for the future policy makers. Afterwards the research underlines the transition from a financing model based on historical public expenditure to a system based on the performance as one of the main innovation in the managerial approach to the health care. The introduction of management thinking will then allow developing a cost-based financing model, an accounting system in the teaching hospital and, finally, a financing system able to pay for services provided by private health care entities. The article then offers also a contribution to policy makers in order to define the "paths" of the Albanian health care system in the next years.  相似文献

Um Bewertungsportale, Blogs, Social Networking Sites, Virtual Worlds etc. im Sinne der Marke verstehen und nutzen zu k?nnen müsse Markenmanager eine Reihe von Spielregeln erlernen und beachten.

Conditional Cooperation and Voluntary Contributions to Public Goods   总被引:10,自引:0,他引:10  
We compare a partners condition , where the same small group of subjects plays a repeated public good game, to a strangers condition , where subjects play this game in changing group formations. From the first period onward, subjects in the partners condition contribute significantly more to the public good than subjects in the strangers condition. Strangers' contributions show continual decay, while partners' contributions fluctuate on a high level prior to decreasing in the final periods. We interpret subjects' behaviour in terms of conditional cooperation which is characterized by both future-oriented and reactive behaviour.

We explore the effects of the COVID-19 crisis and the associated restrictions to economic activity on paid and unpaid work for men and women in the United Kingdom. Using data from the COVID-19 supplement of Understanding Society, we find evidence that labour market outcomes of men and women were roughly equally affected at the extensive margin, as measured by the incidence of job loss or furloughing. But, if anything, women suffered smaller losses at the intensive margin, experiencing slightly smaller changes in hours and earnings. Within the household, women provided on average a larger share of increased childcare needs, but in an important share of households fathers became the primary childcare providers. These distributional consequences of the pandemic may be important to understand its inequality legacy over the longer term.  相似文献
