How does aggregate profit uncertainty influence investment activity at the firm level? We propose a parsimonious adaptation of a factor-autoregressive conditional heteroscedasticity model to exploit information in a subindustry sales panel for an efficient and tractable estimation of aggregate volatility.

We find that higher profit uncertainty induces firms to lower capital expenditure on average, yet to a considerably different...
