An under-explored aspect of body weight is the role that location plays in its determination. To address this evidence gap, this study uses a dynamic event study framework to examine how weight changes for people who change their location and, by extension, how much of the overall variation in weight can be explained by place-based versus individual factors. We then undertake a decomposition analysis on movers and non-movers to determine the role of place in differences in weight between groups of areas. We also model the effects of place on common behavioural correlates of weight. Our results, based on a rich longitudinal survey from Australia, indicate a significant robust place effect on weight. Our event study shows that place is responsible for 15.5% of the variation of weight. We find similarly sized place effects when comparing different groups of areas in our decomposition exercise. Finally, we show that place exerts a strong influence, of around 50% in some cases, on food consumption.

Air pollution affects 99% of the global population at levels exceeding WHO guidelines, yet its impact on governance and civic engagement remains largely unexplored. We combine three waves of the Life in Transition Survey across 29 countries (2006-2016) with high-resolution pollution and meteorological data to examine how air pollution affects corruption perceptions and political participation. Using temperature inversions as instrumental variables for PM2.5 exposure, we find that each additional μg/m³ increases perceived petty corruption by 1.8% overall and 6.4% in EU transition countries, while increasing the odds of perceiving government officials as corrupt by 6-8%. Air pollution also reshapes political participation. Each additional μg/m³ reduces voting by 8-10% while increasing petition signing by 10% in Central and Eastern European countries. This suggests that pollution drives substitution from institutional to non-institutional engagement. Effects concentrate among older, less-educated, and male populations.
