Investment, payout, and cash management under risk and ambiguity

This study extends the theoretical model of dynamic investment, dividend payout, costly external financing, and liquidation for financially constrained firms by incorporating ambiguity. We demonstrate that ambiguity aversion induces a trade-off between the "bird-in-hand" effect and an amplified precautionary motive in determining firms' cash management, which consequently affects firms' investment, dividend payout, costly external financing, and liquidation decisions. Unlike the models considering risk only, we identify a non-monotonic relationship between the endogenous payout boundary and ambiguity aversion. Our model generates several new implications, including providing an explanation for the high cash holdings and speed-up of asset sales during the recent COVID-19 crisis. (c) 2022 Elsevier B.V.
