Grit, discounting, & time inconsistency
研究了心理测量中的毅力（努力坚持和兴趣一致性）与经济上的不耐烦和时间不一致性在普通人群中的关联，发现不耐烦通过努力坚持成分与毅力相关，而时间不一致性与毅力无关。
We study the association of the perseverance of effort and the consistency of interests components of the psychological measure of grit with economic measures of impatience and time inconsistency in the general population. We find that impatience is associated with grit through the perseverance of effort component. No association of time inconsistency with grit is found. Predicting participants' financial and health outcomes and behaviors, we find that impatience and grit are predictive for both outcomes, but this is not the case for time inconsistency. Our findings suggest that it can be beneficial for empirical studies of intertemporal decisions to include economic impatience and psychological grit measures.
