【Abstract】 Deepwater oil and gas projects embody high risks from geologic and engineering aspects, which exert substantial influence on project valuation. But the uncertainties may be converted to additional value to the projects in the case of flexible management. Given the flexibility of project management, this article extends the classical real options model to a multi-factor model which co...

A main issue in valuation modeling is the correct choice of the stochastic process that better describes the asset price performance. Particularly, in investment projects that show a high level of managerial flexibility in conditions of uncertainty – for which it would be proposed the real option valuation models – the assumption of a specific process can have an impact not only on the project ...

Project-financing and public-private partnership schemes are joint projects of investment that are generally submitted to investment valuation criteria based on compound discounting. However, the theoretical basis of these criteria is at issue nowadays. According to recent studies on relational contracting economics and behavioral finance, joint projects of investment can be considered as speci...

The aim of this paper is to generalize the‎ ‎notion of almost valuation domains to arbitrary commutative‎ ‎rings‎. ‎Also‎, ‎we consider relations between almost valuation rings ‎and pseudo-almost valuation rings‎. ‎We prove that the class of‎ ‎almost valuation rings is properly contained in the class of‎ ‎pseudo-almost valuation rings‎. ‎Among the properties of almost‎ ‎valuation rings‎, ‎we sh...

Research supports the effectiveness of a dissonance-based eating disorder prevention program wherein high-risk young women with body dissatisfaction critique the thin ideal, which reduces pursuit of this ideal, and the theory that dissonance induction contributes to these effects. Based on evidence that dissonance produces attitudinal change by altering neural representation of valuation, we te...

This Special Issue of Ecological Economics presents results from The VALSE Project (VALuation for Sustainable Environments), a co-operative international programme of research undertaken during 1996–1998 with the financial support of the European Commission. The research team set out with the goal to demonstrate effective social processes for valuation of environmental amenities and natural cap...
