We use the universe of U.S. job postings to construct a firm-level index that assesses each company’s work from home (WFH) suitability, and study its impact on firms’ resilience during the recent COVID-19 pandemic. Using a difference-in-differences framework, we find strong evidence that, compared to their low-WFH peers, firms with high WFH index values have higher stock returns, lower return volatility, and better financial performance during the pandemic. Our results are robust to stringent empirical specifications that include a variety of fixed effects. Contrary to conventional wisdom, our results hold primarily in non-high-tech industries.
