About The Study: An estimated 3 of 4 U.S. children relied on publicly subsidized insurance (Medicaid, Children’s Health Insurance Program [CHIP], or Marketplace) or experienced a period without any insurance by their 18th birthday in the post-Affordable Care Act (ACA), pre-pandemic policy environment. Substantial state heterogeneity in childhood un-insurance underscores the critical role of Medicaid policies.

The study develops a climate-economy model focusing on three sources of ambiguity: climate sensitivity, climate-related economic damage, and abatement cost-effectiveness. Aversion to climate sensitivity and damage ambiguity increases abatement, while aversion to abatement cost ambiguity reduces it. If the extent of climate change or its damage is believed to be overstated, optimal abatement can drop sharply or even disappear. Perceived relationships among uncertainties can amplify or offset their effects.

A new peer-reviewed study from the Environmental Working Group (EWG) finds that eating certain fruits and vegetables can raise pesticide levels in people’s bodies. Participants who consumed produce with higher pesticide residues – like strawberries, spinach and bell peppers – had significantly more pesticides in their urine than those who ate lower-residue produce. The study combined USDA residue data with CDC biomonitoring information to create a “dietary pesticide exposure score” linking what people eat to pesticide levels in their bodies.

BMJ Group has retracted research suggesting that small daily quantities of apple cider vinegar might help people who are overweight or obese to lose weight. The small clinical trial was published in the open access journal BMJ Nutrition, Prevention & Health in March 2024 and its findings press released. The study findings generated widespread international attention at the time, and continue to be frequently referred to in media coverage.

A model study now explores how carbon pricing with redistribution can help the energy transition and the climate worldwide, while increasing welfare and reducing economic inequality – which is important for enforceability. According to the study, good results would be achieved by a globally uniform carbon price paired with moderate financial transfers to poorer countries, or by a carbon price differentiated by country with domestic revenue recycling. The study was co-authored by the Potsdam Institute for Climate Impact Research (PIK) and published in the top journal Proceedings of the National Academy of Sciences of the United States of America (PNAS).

In 2014, 23 states expanded access to Medicaid. Income for newly eligible individuals in those states were compared to income for those who would have been expanded in the 10 states who chose not to expand access to Medicaid.  “Gaining a better understanding of how increased access to Medicaid impacts individuals across a multitude of dimensions, including economic, is critical for the current political moment in which Medicaid funding faces substantial uncertainty,” said study co-author Becky Staiger, assistant professor of Health Policy and Management at UC Berkeley School of Public Health.
