Surprise, surprise - Measuring firm-level investment innovations

Using the IFO Investment Survey for the German manufacturing sector, we construct a forty-year panel of firm-level investment innovations (surprises). We document the cross-sectional and time-series properties of this panel, and our main findings are: the crosssectional dispersion of investment surprises is countercyclical, as is their average within firm time series volatility, and both are highly correlated. This justifies, in part, strategies in the literature to use cross-sectional moments for the calibration of heteroscedasticity. At the same time, the cross-sectional dispersion of investment is procyclical, suggesting a nonsmooth capital adjustment friction at the micro level. There is substantial dispersion in within-firm volatility, a feature consistent with a recent literature on information frictions at the firm-level. Finally, the aforementioned second moments of investment innovations are Granger-caused by recessions, but not vice versa, rendering simple exogenous uncertainty shocks less plausible as drivers of business cycles.
