Philosophy has long wondered about relations between a happy and an honest, moral life. This book includes chapters on the relationship between the satisfaction with life (the cognitive component of subjective well-being) and happiness. Furthermore, the economics of happiness and subjective well-being (SWB) has been the focus of considerable attention among social scientists recently. All individuals want to be happy, but not everybody is happy. The authors examine the micro and macroeconomic influences on enhancing happiness and SWB. Other chapters aim to help the reader understand: 1. Whether job satisfaction is a key predictor of overall life satisfaction; 2. The relationship between human capital and subjective well-being in several countries; 3. The advantages of proactive coping for expectant mothers' mental health during pregnancy and postpartum; 4. Components of well-being in older adults, including socioeconomic status (SES) and multiple psychological and social factors (including the impact of religion on subjective well-being); 5. The correlation between gratitude and subjective well-being; 6. The effect of quality of governance on subjective well-being; 7. The levels of psychic well-being (PWB) and the differences between individuals' PWB according to their gender, working position and years of service and finally, the study included in the last chapter of the book explores the associations between subjective well-being (happiness, health and self-esteem) religiosity and depression in adolescents.
