Which Workers Bear the Burden of Social Distancing Policies?
In the wake of the coronavirus outbreak, nearly all U.S. states imposed social distancing policies to combat the spread of illness. To the extent that work can be done from home, some workers moved their offices to their abodes. Others, however, are unable to continue working as their usual tasks require a specific location or environment, or involve close proximity to others. Which types of jobs cannot be done from home and which types of jobs require close personal proximity to others? What share of overall U.S. employment falls in these categories? And, given that these jobs will be the ...
Market Structure and Monetary Non-neutrality
I propose an equilibrium menu cost model with a continuum of sectors, each consisting of strategically engaged firms. Compared to a model with monopolistically competitive sectors that is calibrated to the same data on good-level price flexibility, the dynamic duopoly model features a smaller inflation response to monetary shocks and output responses that are more than twice as large. The model also implies (i) four times larger welfare losses from nominal rigidities, (ii) smaller menu costs and idiosyncratic shocks are needed to match the data, (iii) a U-shaped relationship between market ...
Aggregate Recruiting Intensity
We develop an equilibrium model of firm dynamics with random search in the labor market where hiring firms exert recruiting effort by spending resources to fill vacancies faster. Consistent with microevidence, fast-growing firms invest more in recruiting activities and achieve higher job-filling rates. These hiring decisions of firms aggregate into an index of economy-wide recruiting intensity. We study how aggregate shocks transmit to recruiting intensity, and whether this channel can account for the dynamics of aggregate matching efficiency during the Great Recession. Productivity and ...
An SEIR Infectious Disease Model with Testing and Conditional Quarantine
We extend the baseline Susceptible-Exposed-Infectious-Recovered (SEIR) infectious disease epidemiology model to understand the role of testing and case-dependent quarantine. Our model nests the SEIR model. During a period of asymptomatic infection, testing can reveal infection that otherwise would only be revealed later when symptoms develop. Along with those displaying symptoms, such individuals are deemed known positive cases. Quarantine policy is case-dependent in that it can depend on whether a case is unknown, known positive, known negative, or recovered. Testing therefore makes possible ...
