Magnitude Effect on Investment Decisions

Authors

Abstract

Risk and time preferences are essential factors that help to understand the dynamics of human behavior for decision-making. This study aimed to replicate decision-making based on the functional forms derived from the Prospectus Theory in a sample of Brazilian university students with an in-depth analysis with 110 questions (resulting in 2,420 observations), estimating the parameters of risk and time preferences by the maximum likelihood method. We use the model suggested by Harrison, (2008) and Andersen et al. (2008), with the SMPL (Switching Multiple Price Lists), with the theory of hyperbolic discount and the maximum likelihood function. The results showed that the respondents present an asymmetric behavior concerning gains and losses. It was also possible to observe that the discount rate found (daily) in the experiment corresponds to an annual discount rate of 44.0%, considerably high, a result that can be attributed to the so-called 'magnitude effect' in investments.
