|June 2020||Did the Wisconsin Supreme Court Restart a COVID-19 Epidemic? Evidence from a Natural Experiment|
with Dhaval M. Dave, Andrew I. Friedson, Kyutaro Matsuzawa, Joseph J. Sabia: w27322
Both the White House and state governors have explicitly linked thresholds of reduced COVID-19 case growth to the lifting of statewide shelter-in-place orders (SIPOs). This “hardwired” policy endogeneity creates empirical challenges in credibly isolating the causal effect of lifting a statewide SIPO on COVID-19-related health. To break this simultaneity problem, the current study exploits a unique natural experiment generated by a Wisconsin Supreme Court decision. On May 13, 2020, the Wisconsin Supreme Court abolished the state’s “Safer at Home” order, ruling that the Wisconsin Department of Health Services unconstitutionally usurped legislative authority to review COVID-19 regulations. We capitalize on this sudden, dramatic, and largely unanticipated termination of a statewide SIPO to ...
|April 2020||Information and the Persistence of the Gender Wage Gap: Early Evidence from California's Salary History Ban|
with Benjamin Hansen: w27054
Aiming to reduce the gender wage gap, several states and cities have recently adopted legislation that prohibits employers from asking about previously earned salaries. The advocates of these salary history bans (SHBs) have suggested pay history perpetuates past discrimination. We study the early net impact of the first state-wide SHBs. Using both difference-in-difference and synthetic control approaches, we find the gender earnings ratio increased by 1 percent in states with SHBs. We find these population wide increases are driven by an increase of the gender earnings ratio for households with all children over 5 years old, by workers over 35, and are principally driven by those who have recently switched jobs.
|Did California’s Shelter-in-Place Order Work? Early Coronavirus-Related Public Health Effects|
with Andrew I. Friedson, Joseph J. Sabia, Dhaval Dave: w26992
On March 19, 2020, California Governor Gavin Newsom issued Executive Order N-33-20 2020, which required all residents of the state of California to shelter in place for all but essential activities such as grocery shopping, retrieving prescriptions from a pharmacy, or caring for relatives. This shelter-in-place order (SIPO), the first such statewide order issued in the United States, was designed to reduce COVID-19 cases and mortality. While the White House Task Force on the Coronavirus has credited the State of California for taking early action to prevent a statewide COVID-19 outbreak, no study has examined its impact. This study is the first to estimate the effect of SIPO adoption on health. Using daily state-level coronavirus data and a synthetic control research design, we find that ...
