Entrepreneurial overconfidence and SME financing decisions

Overview

This study investigates the relationship between entrepreneurial confidence calibration and external financing access for small and medium-sized enterprises. The research challenges the conventional assumption that overconfidence uniformly impairs financing outcomes by proposing a non-linear relationship. The central thesis posits that moderate overconfidence generates signaling value through demonstrated entrepreneur commitment and effort, which financiers view favorably, whereas extreme overconfidence and underconfidence both result in adverse financing terms.

Methods and approach

The analysis employs a large-scale sample of UK SMEs with a newly developed measurement instrument for entrepreneurial overconfidence. The methodological approach enables testing of non-linear relationships between the confidence measure and multiple financing accessibility outcomes. The study operationalizes financing access through alternative metrics rather than relying on single measures, permitting examination of heterogeneous effects across different financing constraint dimensions.

Results

The empirical findings demonstrate significant non-linear associations between entrepreneurial overconfidence and financing outcomes. Mild overconfidence emerges as a more favorable confidence state compared to both underconfidence and extreme overconfidence, with mildly overconfident entrepreneurs experiencing lower probabilities of credit rationing. This non-monotonic pattern suggests an optimal range of confidence that balances the signaling benefits of demonstrated commitment against the costs imposed by poorly calibrated decision-making.

Implications

The research indicates that financier assessment of entrepreneur quality incorporates multidimensional evaluation beyond traditional risk metrics. The identification of an inverted-U relationship between confidence and financing access suggests that both confidence deficiency and excess generate financing frictions through distinct mechanisms. This finding has relevance for theoretical modeling of information asymmetries in credit markets and the role of entrepreneur characteristics in financing allocation.
