Escalation of Scrutiny: The Gains from Dynamic Enforcement of Environmental Regulations (with Gautam Gowrisankaran and Ashley Langer). Revise and resubmit at the American Economic Review. A problem set built off of this paper is available here

The U.S. Environmental Protection Agency uses a dynamic approach to environmental enforcement for air pollution, with repeat offenders subject to high fines and designation as high priority violators (HPV). We estimate the value of dynamic enforcement by developing and estimating a dynamic model of a plant and regulator, where plants decide when to invest in pollution abatement technologies. We use a fixed grid approach to estimate random coefficient specifications. Investment, fines, and HPV designation are costly to most plants. Eliminating dynamic enforcement would raise emissions damages by 167% with constant fines or raise fines by 533% with constant pollution.

When Threats Become Credible: A Natural Experiment of Environmental Enforcement from Florida Revise and resubmit at the Journal of Environmental Economics and Management. 

Environmental regulators often use dynamic enforcement, which bases penalties and enforcement effort on plants' past compliance history, to improve compliance and decrease emissions when enforcement resources are limited. Using plant-level data from the Environmental Protection Agency (EPA), I examine an unexpected shift in the use of traditional enforcement by environmental regulators in Florida, showing that all of the state’s plants decreased emissions and improved compliance following an increase in penalties for those with Priority Violations. The largest improvements were observed among plants with the highest expected costs of compliance, which is consistent with the theory of dynamic enforcement. These results are robust to the use of control plants from nearby southern states, as well as control plants selected via a matching algorithm. The paper’s findings (1) provide quasi-experimental evidence on the effectiveness of traditional enforcement actions, and (2) suggest that dynamic incentives may matter for plant compliance decisions.

Flaring and Health (with Anatolii Kokoza) Draft Available Upon Request

In this paper we quantify the effect of exposure to flared natural gas on health. Using a unique dataset of well location, flaring, weather, and patient level hospital visits with the five digit zip and diagnostic codes for each patient in the state of North Dakota. We find that exposure to flared natural gas has a negative causal impact on respiratory health. This result accounts for the endogeneity of flaring exposure by using the number of upwind wells connected to a constrained processing plant as an instrument. These results inform current policy debates on the benefits of restrictions on natural gas flaring and the externalities associated with oil activity.
