This study discusses and employs System Generalised Methods of Moments (GMM) dynamic panel analysis to investigate life satisfaction. There are many benefits that such an investigation provides, though commensurate challenges too. Previous attempts to employ dynamic models within life satisfaction research have, in the main and for different reasons, not been wholly successful. This article explains why, how such research can be improved and undertaken in the future, as well as offering insights into life satisfaction and its dynamics. A key insight is that much of the impact of any commonly measured variable on well-being is contemporaneous.
