Deferral and Growth Options Under Sequential Innovation

This paper examines the application of real option theory to sequential investment decision-making. In an effort to contribute to the development of criteria that discriminate between investments that confer growth options from those that confer deferral options, we introduce a conceptual model that explains technological adoption as a sequence of embedded options. Upon the introduction of each successive technological generation, a firm may either defer investment and wait for the arrival of a future generation or invest immediately to obtain experience that provides a claim on adoption of subsequent generations. We propose that deferral and growth option value is dependent on the magnitude, frequency, and uncertainty of inter-generational change, and the nature of rivalry.
