Flexibility and project value: interactions and multiple real options

Abstract

This paper is focused on a project valuation with embedded portfolio of real options including their interactions. Valuation is based on the criterion of net present value (NPV) on the simulation basis. Portfolio includes selected types of European-type real options: option to expand, contract, abandon and temporarily shut down and restart a project. Due to the fact that in reality most of the managerial flexibility takes the form of portfolio of real options, selected types of options are valued not only individually, but also in combination. This paper is structured as follows: firstly, diffusion models for forecasting of output prices and variable costs are derived. Secondly, project value is estimated on the assumption that no real options are present. Finally, project value is calculated with the presence of selected European-type options; these options and their impact on project value are valued first in isolation and consequently in different combinations. Moreover, intrinsic value evolution of gi...
