We present novel evidence of the effect of mental health on productivity using a direct measure of productivity from the COVID-19 modules of the UK Household Longitudinal Study. We employ spatial variation in COVID-19 deaths as an instrumental variable and supplement results by computing bounds by considering coefficient stability to observable factors to infer the influence of unobservables. Our findings reveal a substantive positive relationship between poor mental health and decreased productivity. Our estimates suggest productivity losses of around 54 min per week (on average) for individuals who report a decline in mental health.
