Too much psychological capital? Exploring curvilinear relationships between OPsyCap and performance prior to and after the COVID-19 crisis

PurposePast research has generally purported and tested for a positive linear relationship between psychological capital and organizational outcomes such as firm performance. Yet, recent conceptual work has started to recognize that for certain outcomes, too much psychological capital can be as detrimental as too little. In this study, the author hypothesizes that during a major crisis, organizational psychological capital (OPsyCap) may in fact exhibit an inverted U-shaped relationship with performance.Design/methodology/approachT leverages the revelatory power of a recent major crisis (the COVID-19 pandemic) to gather a pre-crisis and post-crisis matching sample of 952 earnings conference calls held by 476 S & P 500 firms with corresponding market performance data and use computer-assisted text analysis (CATA) methodology to assess OPsyCap from call transcripts.FindingsT finds that OPsyCap has a statistically significant inverted U-shaped relationship with market performance after the crisis, but not prior-thereby suggesting that moderate OPsyCap is more beneficial to market performance than either insufficient or excessive OPsyCap in times of crisis.Practical implicationsTop managers should not display overly excessive psychological capital after a major crisis, as shareholders may interpret such cues as unwarranted optimism, overconfidence and an inability to accept the new reality brought about by the crisis.Originality/valueThis study's findings contribute to extant literature by being the first to empirically highlight a curvilinear relationship between psychological capital and an important outcome variable-market performance. Furthermore, this study's lack of results prior to a major crisis, but not after, may suggest a new boundary condition.
