Chronically ill patients currently consume a significant share of the U.S. health system's resources and are a rapidly growing segment of the overall population. Disease Management (DM) programs identify high-risk patients among the chronically ill, encourage them to take better care of...

How does contagion risk affect the business cycle? We find that the presence of contagion risk significantly alters the transmission of standard macroeconomic shocks. Relative to the first-best equilibrium, the contagion externality significantly reduces the response of output to a technology...

We incorporate age-specific socio-economic interactions in a SIR macroeconomic model to study the role of demographic factors for the COVID-19 epidemic evolution, its macroeconomic outcomes and possible containment measures. Our framework captures the endogenous response of rational individuals...

I investigate how the effect of COVID-19 might diff er across countries, with emphasis on their dependence on income. In particular, I consider two sources of di erences. First, in low income countries there are less jobs that can be performed from home, and second, lower income households...

I study mitigation policies during an epidemic when individuals vary in their degree of interaction with others. Individuals with a high degree are more likely to contract the disease and, once infected, they transmit the disease to more individuals in expectation. Thus, the presence of high...

The COVID-19 is having an unprecedented impact in the commercial and trade sphere globally. Businesses of all sizes are finding it difficult to operate efficiently and many struggle to meet contractual obligations. Agency is a ubiquitous concept in trade and commerce. The sudden implosion of...

This paper studies how wealth and health inequalities have interacted with the Covid-19 epidemic in a way that has reinforced inequalities in income, savings, epidemic risk and even individual preventive behaviors. We present in more detail two papers and their theoretical and empirical results....

How does contagion risk affect the business cycle? We find that the presence of contagion risk significantly alters the transmission of standard macroeconomic shocks. Relative to the first-best equilibrium, the contagion externality significantly reduces the response of output to a technology...

High administrative costs in U.S. health care have provoked concern among policymakers over potential waste, but many of these costs are generated by managed care policies that trade off bureaucratic costs against reductions in moral hazard. We study this trade-off for prior authorization...

In this paper, we test whether the Affordable Care Act Medicaid expansions are associated with in-hospital maternal morbidity. The ACA expansions may have affected maternal morbidity by increasing pre-conception access to health care, and by improving the quality of delivery care through...
