“…Research on the risk attitude of decision‐makers includes risk aversion (Choi et al., 2008; Shen et al., 2019b; Choi et al., 2019; Yuan et al., 2020), risk‐seeking (Arcelus et al., 2006; Choi et al., 2020; Zhao et al., 2021), prospect theory (Schweitzer and Cachon, 2000; Liu et al., 2015), expected utility theory (Kadota et al., 1998; Agrawal and Seshadri, 2000a, 2000b; Monroy et al., 2017), and so on. The behavior of optimism in our paper could be regarded as a kind of risk‐seeking attitude, and only few works study the impacts of optimism on business decision‐making.…”
