The impact of political leader's absence on air quality

Despite a significant amount of academic interest in politicians, there is little empirical research on the impact of their absence on the air quality in the areas under their jurisdiction. This study therefore examines the impact of city leaders' absence on local air quality. Using hand-collected data in Chinese cities from 2003 to 2018, we find that a city leader's absence reduces air pollutant emissions and improves air quality. We also identify two potential channels through which this happens: the disrupted collusion between local leaders and enterprises; and reduced investment. Finally, our findings suggest that the positive relationship between a city leader's absence and improved air quality is attenuated in regions with a better legal environment and stronger religiosity. Our findings provide practical insights for the central government and policymakers to resolve a serious environmental crisis and increase local implementation capacities in environmental governance.
