Contract Type FiledJuly 23rd, 2020where (s, p, i, c) denote respectively subsidiary, parent company, industry and country in which the subsidiary is located, l indicates the hierarchical level at which the subsidiary is placed, L indicates the maximum hierarchical level of the BG, FEp is the parent xed e ect and FEc is the xed e ect for the country in which the subsidiary is located. Please bear in mind that we unify all levels higher than 7 under the same category, 8, so that L ≥ 8.17 To ease the interpretation of this stylized fact, we plot the regression coe - cients and their 95% con dence intervals in Figure 6. This preliminary evidence suggests that, within groups (as we employ parent FE), the complexity of tasks performed by sub- sidiaries positioned in each layer decreases as layers are added to the rst one, since a small value of the routinizability index is associated to a high degree of routinizability of tasks. Again, this is in line with insights from the knowledge-based theory of hierarchies, hinting at t
