Information and Communication Technology (ICT) needs considerable financial resources. In fact, the ICT environment in developing countries is different from that of the developed countries in many aspects. These differences make the impact of an ICT project failure more harmful than that of a developed country especially at the economic level where financial resources are limited. Organization...

Both the economic viability and energy payback time of photovoltaic (PV) systems are inextricably tied to both the electrical performance and degradation rate of PV modules. Different module technologies exhibit different properties in response to varying environmental conditions over time. The purpose of this study is to quantify the effects of those differences on the life-cycle economical co...

Despite being rejected by finance theory, payback continues to be widely used as a method for evaluating capital investment projects. In situations where investment can be delayed, we show that the value of waiting to invest is an increasing function of payback period. Consequently, the optimal investment policy is equivalent to requiring that a project with positive net-present-value be launch...
