Leslie Sanchez, research economist at the USFS Rocky Mountain Research Station presented on Native American water settlement negotiations. Water use in the western United States remains highly concentrated in irrigated agriculture, in part because the first in time, first in right tenets of appropriative water law have insulated irrigators, as senior appropriators, from legal challenges to their water use.

Laura Quinones presented ongoing research on PFAS, also known as “Forever Chemicals," that have become prevalent in domestic water supplies. The long lasting nature of these pollutants is worrisome and highlights the need for policy intervention. The discrepancy between state and federal regulation has led to unequal testing across the US. Data availability is sparse across states and limits our ability to perform policy evaluation surrounding these chemicals.

ARE Ph.D. student Stuart Morrison presented his work on customer responses to variable electricity pricing in Australia. It is becoming increasingly common for energy providers to charge residential consumers a price that is driven by daily electricity markets, rather than a conventional, flat fee. Economic theory suggests that residential consumers will adjust their behavior as prices change throughout the day. But there are many margins along which this adjustment might occur.

Erica Chuang, Ph.D. candidate in the University of California San Diego Department of Economics, presented on principle of targeting for environmental externalities. Economists generally agree that in terms of tax and subsidy structure, Pigou is king. However, market-based instruments that imprecisely target externalities are common, and the degree to which imprecision matters for the objectives of those policies has yet to be fully explored.

Matt Dudek presented his work on the impact of grid-scale battery storage capacity on electricity prices in California. A key barrier to expanding renewable energy production is the daily mismatch between intermittent generation and electricity demand. For example, despite a massive expansion in the low marginal cost solar power production, electricity can only be produced from these sources when the sun is shining.

Yuexuan (Kelly) Wu presented ongoing research on the impact of a deforestation moratorium in Indonesia. Since 2000, Indonesia has seen a 17% reduction in forest cover. Much of the forest loss can be attributed to fires that are used to permanently clear land for agriculture. If the moratorium is effective, we should expect that land-clearing fire activity decreases in areas impacted by the moratorium relative to areas that are not impacted by the moratorium.

Madeline Turland recently presented her job market paper, which explores the factors driving human migration in response to the threat of wildfires and how people's risk preferences impact their choice of where to live. Many individuals opt to move to areas with lower wildfire risk as a strategy for risk reduction. To measure the impact of changes in wildfire risk, she developed a novel data set by using a quirk of California insurance markets.

Laura Alcocer Quinones presented her work on the challenges of aggregating source-level measurements of PFAS for use in policy analysis. Although monitoring for PFAS is common around the United States, the methods and frequency of monitoring are not standardized.

Laura Alcocer Quinones presented plans for a study estimating the health effects of exposure to PFAS (per and polyalyfluoral substances) in drinking water. Exposure to PFAS is associated with kidney disease and complications during pregnancy, such as preeclampsia. However, little is known about the precise relationships between health outcomes and exposure to PFAS through drinking water.

Madeline Turland presented her project on wildfire and wildfire risk adaptation in California's vineyards where she looks at how vineyards adapt in the face of increasing fire and smoke risk.
