Does oil corrupt? We test this theory using forty years of U.S. state-level data measuring corruption as both convictions of corruption and the frequency that words like “corrupt,” “fraud,” and “bribe”— and their iterations—appear in newspapers. We find that oil-rich U.S. states experience more corruption than their oil-poor counterparts, but only during periods of high oil prices, suggesting a causal relationship. Results are robust to a variety of modeling assumptions and specifications. Implications and mechanisms are discussed.
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 pollution exposure and proximity to the fuel switching plants before and after the switch. The use of homes near coal-fired plants that did not innovate strengthens these estimations. The results indicate that the shutdown of coal-fired generators increases property values by 18.8% within 0.5 miles of fuel-switching stations, which brings to light the strong and localized disamenity effect of coal-fired power plants. Back-of-the-envelope calculations suggest that the fuel switching led to a 14.5-million increase in property values around the country.
Ambient air pollution is a major problem in many countries of the developing world. This study examines the relationship between long-term exposure to air pollution and COVID-19-related deaths in four countries of Latin America that have been highly affected by the pandemic: Brazil, Chile, Colombia, and Mexico. Relying on histori- cal satellite-based measures of fine particulate matter concentrations and official vital statistics, our results suggest that an increase in long-term exposure of 1 μg/m3 of fine particles is associated with a 2.7 percent increase in the COVID-19 mortality rate. This relationship is found primarily in municipalities of metropolitan areas, where ur- ban air pollution sources dominate, and air quality guidelines are usually exceeded. Our findings support the call for strengthening environmental policies that improve air quality in the region, as well as allocating more health care capacity and resources to those areas most affected by air pollution.
The Health Benefits of Solar Power Generation: Evidence from Chile (with Beia Spiller and Cristobal Ruiz-Tagle). Environmental Defense Fund Economics Discussion Paper Series, EDF EDP 21-02 [Link][Blog Post]
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 data gathered during the rapid adoption of large-scale solar power generation in Chile over the last decade. Relying on exogenous variation from incremental solar generation capacity over time, we find that solar energy displaces fossil fuel generation (primarily coal-fired generation) and curtails hospital admissions, particularly those due to lower respiratory diseases. These effects are noted mostly in cities downwind of displaced fossil fuel 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.
Do resource extraction booms crowd out postsecondary educational investments? We shed light on this question by exploring higher education enrollment and completion decisions of Chilean high school seniors who graduated during the 2000scommodities boom. For identification, we rely on exogenous variation that come from copper prices along with the pre-treatment spatial distribution of mineral leases throughout the country. We find that mining booms do not affect students’ likelihoodof enrolling in a postsecondary education. However, there is a significant effect in the likelihood of dropping out from college, especially from a four-year professional degree program. An examination of potential mechanisms reveals that lower returns to higher education and fewer inputs available to primary and secondary schools in resource-rich areas seem to be driving the results. Our findings constitute strong evidence that natural resources may severely affect human capital accumulation in resource-rich places, resulting in detrimental long-term consequences for economic development and growth.
