abstract: 'Purpose - This paper investigates the determinants of subjective well-being in Europe using the European Living, Working and COVID-19 (ELWC) Survey carried out by Eurofound (2021). Socio-demographics characteristics, employment status, measures of economic distress, inequality and work life balance are considered. Particular attention is paid to how quality of government support (QGS), that considers the dimensions of good governance such as integrity, fairness, reliability, responsiveness and influences subjective mental well-being (WHO-5) through the mediation of trust in other people and in institutions. Design/methodology/approach - To this end, the authors estimate a moderated mediation model for analysing the indirect role of QGS on WHO-5 through institutional trust and trust in people. Findings - The results support the hypothesis that the reduction in WHO-5 in the European population during coronavirus disease 2019 (COVID-19), particularly marked in the 18-34 age group, is related to the perceived inadequacy of government interventions in managing economic and social uncertainty through supportive measures. This outcome is also due to reduced trust in institutions and other people, as both are significant mediators that reinforce the impact of public support on WHO-5. Practical implications - Government should pay greater attention to this relationship amongst good governance, trust and mental health of citizens because a healthy human capital is a significant factor for the long-run economic growth, in a special way when the authors refer to the young workforce with a greater life expectancy. Originality/value - In the literature, the role of trust as a mediator has been analysed in the relationship between individual economic situations and subjective well-being before and during the COVID-19 pandemic. To the best of the authors'' knowledge, no studies have examined the role of perceived QGS on subjective mental well-being using the mediating and backing effects of trust in people and institutions.
