The COVID-19 pandemic has led to a “second pandemic” of anxiety and depression. While vaccines are primarily aimed at reducing COVID-19 transmission and mortality risks, they may have important secondary benefits. We use data from U.S. Census Bureau’s Household Pulse Survey merged to...

The COVID-19 pandemic has forced federal, state and local policymakers to respond by legislating, enacting, and enforcing social distancing policies. However, the impact of these policies on healthcare utilization in the United States has been largely unexplored. We examine the impact of...

Colorectal cancer is the second leading cause of cancer-related mortality, but the cost-sharing environment for colonoscopies, the preferred form of screening, is complex. This paper combines a machine learning-based double-selection algorithm to perform principled covariate selection with...

Price transparency initiatives have recently emerged as a solution to the lack of health care price information available to consumers. This paper uses the staggered and nationwide diffusion of a leading internet-based price transparency platform to estimate the effects of price transparency on...
