Pollution, Health and Housing Markets : Essays on the Consequences of Environmental Policy
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The objective of the thesis is to estimate the health and housing market effects of environmental policies and estimate how these effects are distributed among individuals.The first essay estimates the health effects of a noise mitigation program that provided dwelling insulation and noise barriers. The analysis is based on hospitalization records and an event study model that compares disease rates for residents in treated homes to residents with similar attributes in untreated homes. Results show that noise mitigation reduced the risk of a cardiovascular disease by 12–14 percent after ten years. Effects are driven by a reduced risk of hypertension and stroke and occur primarily among those with lower income and education levels.The second essay investigates the impact of the same noise mitigation program on property prices. Using records on sales prices and property attributes in a difference-in-difference model, I estimate the price effect to be 10–12 percent, with larger price effects for homes with poor initial exterior quality. Price gains are smaller for top earners, since they sort to high-quality properties that benefit less from noise mitigation.The third essay examines how information about pollution affects neighborhood composition and households' choice of housing quality. Combining data on sales prices, property attributes and household demographics, I find that the announcement of an airport concession renewal induced higher-income households to sort away from the area exposed to airport pollution. Higher-income households that located to the area selected homes with better quality. These results help reconcile mixed findings on residential sorting behavior in the literature.The fourth essay estimates the effect of shipping emission standards on air quality and health. The tightening of the sulfur emission standard reduced concentrations of sulfur dioxide by 22 percent and fine particles by 6 percent. In the subsample with air quality readings, the risk of low birthweight dropped by 7 percent.

Tidskriftsartikel (refereegranskat)abstract
- Use of menopausal hormone therapy (MHT) is associated with increased risk for breast cancer. However, the relevant mechanisms and its interaction with genetic variants are not fully understood. We conducted a genome-wide interaction analysis between MHT use and genetic variants for breast cancer risk in 27,585 cases and 34,785 controls from 26 observational studies. All women were post-menopausal and of European ancestry. Multivariable logistic regression models were used to test for multiplicative interactions between genetic variants and current MHT use. We considered interaction p-values < 5 x 10(-8) as genome-wide significant, and p-values < 1 x 10(-5) as suggestive. Linkage disequilibrium (LD)-based clumping was performed to identify independent candidate variants. None of the 9.7 million genetic variants tested for interactions with MHT use reached genome-wide significance. Only 213 variants, representing 18 independent loci, had p-values < 1 x 10(5). The strongest evidence was found for rs4674019 (p-value = 2.27 x 10(-7)), which showed genome-wide significant interaction (p-value = 3.8 x 10(-8)) with current MHT use when analysis was restricted to population-based studies only. Limiting the analyses to combined estrogen-progesterone MHT use only or to estrogen receptor (ER) positive cases did not identify any genome-wide significant evidence of interactions. In this large genome-wide SNP-MHT interaction study of breast cancer, we found no strong support for common genetic variants modifying the effect of MHT on breast cancer risk. These results suggest that common genetic variation has limited impact on the observed MHT-breast cancer risk association.
