Abstract Using the first reported case of COVID-19 in a given U.S. county as the event day, we find that firms headquartered in an affected county experience, on average, a 27-bps lower return in the 10-day post-event window. This negative effect nearly doubles in magnitude for firms in counties with a higher infection rate (−50 bps). We test a number of transmission channels. Firms belonging to labor-intensive industries and those located in counties with a large mobility decline have worse stock performance. Firms sensitive to COVID-19-induced uncertainty also exhibit more negative returns. Finally, more negative stock returns are associated with downward revisions in earnings forecasts.

ABSTRACT We examine the relative pricing of nominal Treasury bonds and Treasury inflation‐protected securities in the presence of U.S. default risk. Hedged breakeven inflation is significantly positively related to U.S. default risk, driven by correlation between shocks to default risk and both shocks to inflation swap premia and Treasury yields. To understand the mechanisms through which default risk is related to inflation swaps and sovereign yields, we estimate an affine term structure model to capture their joint dynamics. Our estimation implies that the interaction between inflation dynamics and default is the primary source of differential pricing.
