Abstract: The impact of unconventional oil and gas development on water quality is a major environmental concern. We built a large geocoded database that combines surface water measurements with horizontally drilled wells stimulated by hydraulic fracturing (HF) for several shales to examine whether temporal and spatial well variation is associated with anomalous salt concentrations in United States watersheds. We analyzed four ions that could indicate water impact from unconventional development. We found very small concentration increases associated with new HF wells for barium, chloride, and strontium but not bromide. All ions showed larger, but still small-in-magnitude, increases 91 to 180 days after well spudding. Our estimates were most pronounced for wells with larger amounts of produced water, wells located over high-salinity formations, and wells closer and likely upstream from water monitors.

TL;DR: In this article, the authors argue that the complexity of today's societal and environmental challenges calls for an interdisciplinary approach, and they develop the idea that, if bridges cannot be built across paradigmatic divides, tensions can be harnessed productively by nurturing academic empathy.

TL;DR: In this paper, the authors discuss the use of narrative reporting, both in relation to financial and non-financial information, with significant managerial discretion regarding content, in the context of financial reporting.
Abstract: Narrative reporting, both in relation to financial and non-financial information, is increasingly used and often mandated, with significant managerial discretion regarding content. As policy makers...

TL;DR: In this paper, the authors extend prior research by examining whether the mere presence of a standalone CSR report mitigates negative market reactions at times of regulatory cost exposure and find that only the environmental disclosures appear to reduce negative market effects.
Abstract: A growing number of studies use a dichotomous variable indicating the presence of a standalone CSR report to capture impacts of CSR disclosure. Our concern is that, without considering differences in the information provided, such an approach could lead to incorrect inferences regarding those impacts. Accordingly, we extend prior research by examining whether, similar to differences in environmental disclosure, the mere presence of a standalone CSR report mitigates negative market reactions at times of regulatory cost exposure. We focus on the 2011 Fukushima Daiichi disaster and a sample of international utilities with nuclear power generation. Controlling for other factors related to social and regulatory cost exposures, we find only the environmental disclosures appear to reduce negative market effects. We thus argue that, in exploring the impacts of CSR disclosure, researchers need to carefully consider, beyond just the presence of a CSR report, differences in the extent of information being provided.
