His Ph.D. project examines the impact of the COVID-19 pandemic on the subjective wellbeing of people in Bangladesh. Considering the increasing focus on improving people's subjective wellbeing within the broader global development agenda, this study undertakes a comprehensive analysis of subjective wellbeing using Bangladesh as a case study. The specific objectives are to 1) analyze the current status and future research needs on subjective wellbeing with a particular focus on sustainable development goals (SDGs); 2) to determine subjective wellbeing set points (short-run adjustments and long-run equilibrium); 3) to examine whether there are any differences in subjective wellbeing set points across countries with a particular focus on the COVID-19 pandemic; 4) to analyze the important domains of life satisfaction in Bangladesh with a special emphasis on the SDGs and COVID-19 pandemic; 5) to identify the sociodemographic and economic determinants of life satisfaction in Bangladesh, and 6) to develop a Composite Subjective Wellbeing Index (CSWBI) for Bangladesh. Data will be collected from various sources and analyzed using appropriate econometric models to accomplish the objectives. The application of the subjective wellbeing approach in economics is relatively new. Hence, this research has immense potential to significantly contribute to the scientific community, in general, and formulate and implement national policies in Bangladesh, in particular.
