“…Since differences in self-perceptions have been attributed to, inter alia, gender stereotypes (Niederle and Vesterlund, 2007) and metacognitive skills (Kruger and Dunning, 1999), we take particular care in allowing for potential gender disparities and gaps in formal education. In doing so, we complement the earlier literature on behavioral biases in financial decisions that has mainly considered the choices of male experts, for instance executive managers (Gervais, Heaton, and Odean, 2011;Adam, Fernando, and Golubeva, 2015;Huang, Tan, and Faff, 2015), portfolio managers (Puetz and Ruenzi, 2011;Gloede and Menkhoff, 2014) or traders (Hirshleifer and Luo, 2001;Palomino and Sadrieh, 2011;Sonsino and Regeff, 2013). Less is known about the impact of self-confidence on male and female amateurs' financial decisions and wealth accumulation.…”
