Using euro area firm-level data since the recent financial crisis, we test whether bank lending constrained small- and medium-sized enterprises (SMEs) are more likely to use or apply for alternative external finance including trade credit, informal lending, loans from other companies, market financing (issued debt or equity) and state grants. Our constraint indicators identify both credit-rationed firms and firms that self-ration due to high lending costs. We find that credit-rationed firms are more likely to use, and apply for, trade credit. This increases with firm size and age. We also find that constrained firms are more likely to use informal lending or loans from other companies but find no evidence that bank-constrained SMEs apply for, or use, market finance. Smaller, self-rationing borrowers are more likely to apply for grant finance. Finally, we find that firms denied credit for working capital tend to turn to trade credit, while informal and inter-company lending tends to act as a substitute for bank investment loans.

This paper examines the extent to which bank market power alleviates or magnifies SME credit constraints using a large panel dataset of more than 118,000 SMEs across 20 European countries over the period 2005–2008. To our knowledge, this is the first study to examine bank market power and SME credit constraints in an international, developed economy setting. Moreover, our study is the first to address a number of econometric considerations simultaneously, in particular by controlling for the availability of profitable investment opportunities using a structural Q model of investment. Our results strongly support the market power hypothesis, namely, that increased market power results in increased financing constraints for SMEs. Additionally, we find that the relationship exhibits heterogeneity across firm size and opacity in a manner that suggests that the true relationship between bank market power and financing constraints might not be fully explained by the existing theory. Finally, we find that the effect of bank market power on financing constraints increases in financial systems that are more bank dependent.
