Description:
Although the link between risk aversion and diminishing marginal utility of wealth is academically well established, theoretical discussions concerning its empirical validity remain. The presented, review-type paper aims to briefly examine theoretical roots responsible for the different views on this association in order to provide a broader perspective to alternative explanations. This latter task is assisted by comparative analysis of two recent pieces of research by Rick Falkenstein and Matthew Rabin; a duo of papers, handpicked at the author's discretion to demonstrate the convergence of alternative ideas from different authors (and backgrounds). In support of its argumentation, the paper also presents a critical overview of the equity premium puzzle as seen through the prism of behavioural finance. The main contributions of the paper include evidence-based support for the concept of relative utility and reconfirmation of the meaningful role of behavioural finance in economics and finance.
