Air Quality Warnings and Temporary Driving Bans: Evidence from Air Pollution, Car Trips, and Mass-Transit Ridership in Santiago (R&R, JEEM)[Paper]
Driving restrictions are a common governmental strategy to reduce airborne pollution and traffic congestion in many cities of the world. Using high-frequency data on air pollution, car trips, and mass-transit systems ridership, I evaluate the effectiveness of temporary driving bans triggered by air quality warnings in Santiago, Chile. I employ a fuzzy regression discontinuity design that uses the thresholds in the air quality index used to announce these warnings as instruments for their announcement. Results show that these temporary bans reduce car trips by 6-9% during peak hours, and by 7-8% during off-peak hours. This is consistent with air pollution reductions during peak hours, and with increases in the use of Santiago’s mass-transit systems during hours the systems run with excess capacity. Increments in mass-transit ridership uncover the importance of alternatives modes of transportation in securing the effectiveness of temporary driving bans.
We derive causal property value impacts of the coal-to-gas fuel switching conversion implemented by several power plants in the United States. We use an extensive dataset of property transactions around the country and adopt several spatial difference-in-difference approaches that use records of residential property transactions of homes with wind exposure and proximity to the switching plants before and after the switch. A triple-differences control function estimator using coal-fired plants that did not innovate strengthens these estimations. Our results indicate that the shutdown of coal-fired generators increases property values of downwind homes by 15% in the immediate vicinity of fuel-switching plants (< 1.2mi), which brings to light the strong disamenity effect of coal-fired power plants. Our back-of-the-envelope calculations suggest that the fuel switching led to a $1.78 billion-increase in property values around the country.
Does oil corrupt? We test this theory using forty years of U.S. state-level data measuring corruption as both convictions of public corruption and the frequency that words like “corrupt,” “fraud,” and “bribe”— and their various iterations—appear in newspapers. We find that oil-rich U.S. states are significantly more corrupt than their oil-poor counterparts, particularly during periods of high oil prices, suggesting an underlying causal relationship. Our findings are robust to a variety of modeling assumptions and specifications suggesting that oil plays an indirect, critically important, and yet previously overlooked role in shaping public policy and economic outcomes in the United States.
Renewable energy can yield social benefits through local air quality improvements and their subsequent effects on human health. We estimate some of these benefits using the rapid adoption of solar power generation experienced by Chile over the last decade. Using daily variation in generation, we find that solar energy (1) displaces fossil-fueled generation, primarily coal-fired generation, and (2) curtails hospital admissions —particularly those due to upper and lower respiratory diseases. These effects are noted mostly in cities downwind the displaced fossil-fueled generation, and are present across all age groups. Our results document the existence of an additional channel through which renewable energy can increase social welfare.
