We study the impact of non-pharmaceutical policy interventions (NPIs) like "stay-at-home" orders on the spread of infectious disease. Local policies have little impact on the economy nor on local public health. Stay-at-home is only weakly associated with slower growth of Covid-19 cases....

We study the interaction of search and application approval in credit markets. We combine a unique dataset, which details search behavior for a large sample of mortgage borrowers, with loan application and rejection decisions. Our data reveal substantial dispersion in mortgage rates and search...

We incorporate a search-theoretic model of imperfect competition into an otherwise standard model of asymmetric information with unrestricted contracts. We develop a methodology that allows for a sharp analytical characterization of the unique equilibrium, and then use this characterization to...

Infectious disease is currently the main cause of mortality in the world and has been even more important historically. This paper reviews recent research in economic epidemiology. Specifically, it discusses the occurrence of infectious diseases and the effects of public health interventions...

Using randomized methodologies, we study a common community HIV/AIDS program that seeks to promote HIV testing by improving knowledge and reducing stigmatizing attitudes. Contrary to expectations, the program has a substantial negative effect on HIV testing rates. We provide evidence of likely...

This paper studies the immediate and long-run mortality effects of the first community-based health intervention in the world - the Framingham Health and Tuberculosis Demonstration, 1917-1923. The official evaluation committee and the historical narrative suggest that the demonstration was...

We discuss and review literature on the macroeconomic effects of epidemics and pandemics since the late 20th century. First, we cover the role of health in driving economic growth and well-being and discuss standard frameworks for assessing the economic burden of infectious diseases. Second, we...

The Covid-19 pandemic has motivated a myriad of studies and proposals on how economic policy should respond to this colossal shock. But in this debate it is seldom recognized that the health shock is not entirely exogenous. Its magnitude and dynamics themselves depend on economic policies, and...

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...

We present a general framework for Bayesian estimation and causality assessment in epidemiological models. The key to our approach is the use of sequential Monte Carlo methods to evaluate the likelihood of a generic epidemiological model. Once we have the likelihood, we specify priors and rely...
