This paper estimates the impact on Delhi’s air quality of a number of policy measures recently implemented in the city to curb air pollution using monthly time-series data from 1990 to 2005. The best known of these measures is the court-mandated conversion of all commercial passenger...

We study the short-term effects of the 9-Euro-Ticket, a major German public transport subsidization program, on particulate matter (PM). Using hourly PM readings from pollution monitoring stations throughout Germany, provided by the German Federal Environmental Agency, we find declines in...

This paper studies the impact of speed limits on local air pollution using a series of datespecific speed limit reductions in Oslo over the 2004-2011 period. We find that lowering the speed limit from 80 to 60 km/h reduces travel speed by 5.8 km/h. However, we find no evidence of reduced air...

We investigate the heterogeneous effects of daily particular matter (PM) pollution on Italian hospitalizations and their costs. We exploit public transportation strikes as plausibly-exogenous shocks in PM. We find that young individuals, an arguably healthy age group, exhibit economically...

A large proportion of local pollutants originating from the road transport sector is generated during the so-called cold-start phase of driving, that is, the first few minutes of driving after a car has stood inactive for several hours. Drawing on data from the German Mobility Panel (MOP), this...

Most highways in urban China are tolled to finance their construction. During the eight-day National Day holiday in 2012, highway tolls were waived nationwide for passenger vehicles. We use this to identify the effects of highway tolls on air pollution. Using daily pollution and weather data for...

We exploit a unique panel of 75 metro areas (‘cities') across the globe and employ a city-fixed effects model to identify the determinants of within-city changes in air pollution concentration between 2005 and 2011. Increasing car and population densities significantly reduce air pollution...

Many governments have banned strikes in public transportation. Whether this can be justified depends on whether strikes endanger public safety or health. We use time-series and cross-sectional variation in powerful registry data to quantify the effects of public transit strikes on urban...
