Summary

Research Question: To what extent does external equity financing substitute for debt financing during a banking crisis? Specifically, how do German private firms adjust their financing mix when reliant on a large German bank subject to an exogenous loan supply cut during the Great Financial Crisis?

Key Findings:

1. Equity Substitution: For each 1 euro reduction in debt financing post-crisis, German private firms received approximately 0.27 euros of external equity, supporting the "spare tire" hypothesis (equity substitutes for debt).
2. Source of Equity: During the crisis, equity injections were primarily provided by existing owners (60%) in 40% of firms that received injections. New owners (outsiders) provided equity in the remaining firms.
3. Real Effects: Highly dependent firms experienced larger decreases in debt but also saw reductions in tangible capital investment and overall financial capital availability. However, external equity injections helped mitigate these negative effects.
4. Bank Dependence: Firms highly dependent on Commerzbank (4.8% of sample) faced sharper declines in debt but also higher equity injections compared to moderately dependent (7.1%) and non-dependent (81.4%) firms.

Context and Significance: The study uses detailed firm-level data and bank relationships to establish a causal link between an exogenous banking crisis shock and corporate financing adjustments. It highlights the importance of multiple intermediation sources for economic resilience and imperfections in Macro-Finance models that often overlook equity financing dynamics.
