4. Conclusion
In this study we examine the effects of ambiguity on corporate financial decisions and cash holdings. Following the capacity approach, we describe the firm value as a Choquet Brownian process, and predict that greater ambiguity will lead firms to decrease equity, increase debt and enter financial distress earlier. This study offers several contributions. First, we contribute to the ambiguity literature regarding the impact of ambiguity on corporate financial decisions, which has never been studied in a real-option framework like ours. Second, we contribute to the theoretical debate about the conditions under which a pecking order for the issuing of securities exists. Finally, we examine in which manner ambiguity affects corporate cash holdings. We show that cash holdings are retained longer if the investors' ambiguity aversion bias is sufficiently large, while cash holdings become less attractive when the combined impact of ambiguity and ambiguity aversion is relatively low. Overall, our results shed new light on some biases in corporate beliefs, which have implications for corporate finance. Our study shows that perceived ambiguity is a determinant in behavioural corporate fi- nance and significantly affects managerial decisions.
