Webb13 juni 2024 · In this study, we investigate whether self-distancing can reduce the probability-weighting biases. Self-distancing refers to individuals' cognitive strategy of assuming a third-person perspective to psychologically remove themselves from the events that happen to them ( Kross et al., 2005; Kross and Ayduk, 2024 ). WebbInverse probability weighting relies on building a logistic regression model to estimate the probability of the exposure observed for a particular person, and using the predicted …

Propensity Score Weighting in R: A Vignette
WebbIn this paper we analyze how changes in inverse S-shaped probability weighting influence optimal portfolio choice in a rank-dependent utility model. We derive sufficient conditions for the existence of an optimal solution of the investment problem, and then define the notion of a more inverse S-shaped probability weighting function. Webb30 nov. 2024 · As theory predicts, probability weighting is positively associated with portfolio underdiversification and significant Sharpe ratio losses. Analyzing respondents’ individual stock holdings, we find higher probability weighting is associated with owning lottery-type stocks and positively skewed equity portfolios.
