Small and Vulnerable during Crises? Firm Size and Financing Constraints Dynamics

This study analyzes the dynamics of financing constraints under changing economic conditions and the role of firm size in this context. Using administrative data from Germany, we quantify financing constraints expressed as the probability that a firm encounters excess demand or excess supply. On average, small and medium-sized enterprises (SMEs) are indeed more likely than larger firms to face excess demand for loans. Using the Great Financial Crisis as an empirical setting, we show that tightening financing conditions do not affect smaller firms disproportionally, but generally risky borrowers. Importantly, post-crisis trends in debt-ratios, profitability, investments, and employment are similar irrespective of firm size, while smaller firms respond to the economic slowdown by persistently building up cash buffers. Our results urge policymakers to consider specific characteristics of bank-dependent firms to assess their exposure to economic crises - instead of focusing on size as a vulnerability criteria per se.
