Does debt overhang distort only investment? This paper analyzes the subsequent effects of debt overhang on firm-level outcomes. Using an event study for German firms from 2004 to 2021, we find that, relative to comparable firms in the same industry and year, highly indebted firms do not merely invest less, which is the classic overhang result. They also hire less, and the two margins together translate into slower sales growth. The composition of the adjustment, however, depends on the firm’s growth regime. Highly indebted firms that keep expanding slow their hiring but raise capital per worker over the long run, substituting capital for labour along a flatter expansion path. Highly indebted firms that contract shed workers with no offsetting change in capital intensity: they scale down rather than restructure. These patterns hold in normal times as well as in crises and are concentrated among small and medium-sized limited-liability firms. Debt overhang is therefore not a pure investment wedge but a persistent drag on firm scale, whose incidence across inputs is determined by whether the firm is growing or shrinking.

Das britische Wirtschaftsmagazin The Economist hat die Wirtschaftspolitik der Regierung Trump als „Fortress Economics“ bezeichnet. Bei der Festung USA werden alle Zugbrücken hochgezogen. Importe werden mit dem expliziten Ziel durch Zölle verteuert, um (fast) alle Produkte wieder in den USA zu produzieren. Und die Grenzen der USA, nicht nur nach Mexiko, sind fast vollständig geschlossen.

This paper provides theory and evidence on micro-level pricing behavior needed to model an aggregate New Keynesian Phillips Curve. We start with individual firms that are heterogeneous in their production technology and in the demand curves they face. We estimate the parameters of supply and demand curves by utilizing prices and quantities of outputs and factor inputs of firms along with exogenous downstream demand instruments from global input-output and trade data. The research addresses model heterogeneity using a clustering method to classify firms according to their production technology and observed price pass-through. The results show that more productive firms exhibit a lower price response to changes in demand. We find that the aggregate price response to demand shocks will be smaller when more productive firms absorb a larger portion of demand shocks, which generally is the case. At the same time, our results imply that idiosyncratic shifts in demand to clusters of firms with more rapidly rising marginal cost curves, or cost shocks to clusters of firms with high pass-through, will result in a higher aggregate price response. Finally, this paper provides a framework to incorporate heterogeneous pricing behavior into an estimate of the slope of the aggregate Phillips Curve.
