Layoff Contagion Map

When one company in a sector lays off, peer companies follow — peer herding is statistically proven. Academic research (Vale 2023, PNAS Nexus) models tech layoff propagation using the same SIR framework epidemiologists use for infectious disease. We apply it in real time to every sector in our database.
