Uncertainty and sectoral shifts: The Interaction between firm-level and aggregate-level shocks, and macroeconomic activity
This study predicts and finds that the interaction of firm-level and aggregatelevel shocks explains a significant portion of shocks to macroeconomic activity. Specifically, we hypothesize that the relation between uncertainty and economic growth is most pronounced when both firm-level and aggregate-level uncertainty are high simultaneously. Similarly, we hypothesize that aggregate performance affects unemployment most when both firm-level dispersion is high and aggregate performance is low, based on the sectoral shift theory. Our hypotheses and empirical results show that the interactive effect of firm-level and aggregate-level shocks are larger than the sum of the individual effects.
