When Do Shelter-in-Place Orders Fight COVID-19 Best? Policy Heterogeneity Across States and Adoption Time -- by Dhaval M. Dave, Andrew I. Friedson, Kyutaro Matsuzawa, Joseph J. Sabia

Shelter in place orders (SIPOs) require residents to remain home for all but essential activities such as purchasing food or medicine, caring for others, exercise, or traveling for employment deemed essential. Between March 19 and April 20, 2020, 40 states and the District of Columbia adopted SIPOs. This study explores the impact of SIPOs on health, with particular attention to heterogeneity in their impacts. First, using daily state-level social distancing data from SafeGraph and a difference-in-differences approach, we document that adoption of a SIPO was associated with a 5 to 10 percent increase in the rate at which state residents remained in their homes full-time. Then, using daily state-level coronavirus case data collected by the Centers for Disease Control and Prevention, we find that approximately three weeks following the adoption of a SIPO, cumulative COVID-19 cases fell by 44 percent. Event-study analyses confirm common COVID-19 case trends in the week prior to SIPO adoption and show that SIPO-induced case reductions grew larger over time. However, this average effect masks important heterogeneity across states — early adopters and high population density states appear to reap larger benefits from their SIPOs. Finally, we find that statewide SIPOs were associated with a reduction in coronavirus-related deaths, but estimated mortality effects were imprecisely estimated.

Brandt fled his native Germany for Norway after the rise of the Nazis in the 1930s. Returning after the war, he became involved in politics and, in 1969, was elected chancellor of the Federal Republic of Germany.

England's Lincoln Cathedral Is Consecrated (1092)

Not long after William the Conqueror named Remigius de Fécamp bishop of what was then the largest diocese in the country, he decided to move the seat of the diocese to a more central location. For the next 20 years, Remigius oversaw construction of a magnificent new cathedral in Lincoln, only to die days before its consecration. Today, its architecture is considered to be priceless. When Queen Eleanor died nearby in 1290, which parts of her body were buried at the cathedral? Discuss
