<p>Although the Coronavirus disease (COVID-19) pandemic has ended, it remains unclear whether there are any hysteresis effects on the psychological dimension, especially in terms of economic mentality. To address this question, we propose a model of economic mentality that allows us to derive whether and how public’s economic mentality changed in the post-pandemic era. First, factor analysis was conducted on two nationally representative survey datasets collected during and after the pandemic to obtain a stable three-dimensional model of economic mentality. The model includes affective (i.e., well-being, satisfaction with family finances, and perceived income fairness), cognitive (i.e., attributions of wealth and poverty, and willingness to redistribute), and behavioral intention (i.e., government market control) dimensions. Second, the results of hierarchical multiple regression showed that economic mentality changed in varying ways across different indicators in the post-pandemic period compared to during the pandemic. In the affective dimension, there were significant increases in well-being and satisfaction with family finances but decreased perceived income fairness. In the cognitive dimension, people were more likely to attribute the gap between wealth and poverty to external circumstances and were more willing to redistribute. In the behavioral intention dimension, people desired more government control over the market. These findings contribute to understanding the changes in the public’s economic mentality and the psychological mechanisms behind economic operations in the post-pandemic period.</p>
