High-technology projects are known as tools that help achieving productive forces through scientific and technological knowledge. These knowledge-based projects are associated with high levels of risks and returns. The process of high-technology project and project portfolio selection has technical complexities and uncertainties. This paper presents a novel two-parted method of high-technology ...

This paper presents an economic evaluation of gas to liquids (GTL) project using “South-Pars” gas field of Iran based on the latest actual performing GTL projects. Iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of GTL products which have lower pollution and higher quality than refinery products. The results of cost-benefit analysis sho...

Nowadays, most important projects are studied by project network methods but, unfortunately, gaps and deviations between the theoretical results and the achieved ones tend to be systematically large. Traditionally modelling of uncertainty has been based on the assumption that the duration of each activity follows an independent random variable as it is the case of PERT. However, this model is t...

To date the literature on subjective well being has focused on the developed economies. We provide empirical evidence from two emerging market countries, Peru and Russia. Our results—and in particular a strong negative skew in the assessments of the respondents with the greatest income gains—support the importance of relative rather than absolute income differences. Among other factors, we attr...
