Decarbonization and electrification will require a transformed electricity grid. Our long-run model of entry and exit of generation and storage capacity captures crucial aspects of the electricity industry such as time-varying demand for electricity, intermittency of renewables, and...

In periods of high energy demand, utilities frequently issue "emergency" appeals for conservation over peak hours to reduce brownout risk. We estimate the impact of such appeals using high-frequency data on actual and forecasted electricity generation, pollutant emission measures, and real-time...

We estimate the impact of piped water and sewers on property values in mid-19th century Chicago. The cost of sewer construction depends sensitively on imperceptible variation in grade, and such variations in grade delay water and sewer service to part of the city. This delay provides...

We study public vs. private provision of health care for veterans aged 65 and older who may receive care provided by the US Department of Veterans Affairs (VA) and in private hospitals financed by Medicare. Utilizing the ambulance design of Doyle et al. (2015), we find that the VA reduces 28-day...

How does the publication of patents affect innovation? We answer this question by exploiting a large-scale natural experiment--the passage of the American Inventor's Protection Act of 1999 (AIPA)--that accelerated the public disclosure of most U.S. patents by two years. We obtain causal...
