Author

  • Rieger, Marc Oliver

Abstract

We show that security-potential-aspiration theory (SP/A) and cumulative prospect theory (CPT), although based on very different psychological principles are mathematically very similar when studied in the appropriate framework. This helps to interpret results on portfolio optimization under behavioral preferences.
