摘要 (Abstract):

Weconsider a model of dynamic investment, financing, and liquidity management forfinancially constrained firms under risk and ambiguity. We examine and differentiatethe impact of risk and ambiguity on (i) firm value-capital ratio, (ii) dividendpolicy, (iii) marginal value of cash, and (iv) investment-capital ratio,respectively, in two cases: liquidation and refinancing. We find that theeffect of ambiguity is drastically different from that of traditional risk.Specifically, an increase in ambiguity first decreases and then increases thecash holdings while an increase in risk increases the cash holdingsmonotonically. Compared to the usual precautionary effect due to future risk ofliquidation or costly external financing, we clarify that ambiguity aversionbias brings an effect of “a bird in the hand” (prefer dividend payments) and anadditional precautionary effect (prefer cash hoarding). Consequently, there isa trade-off between the two counteracting effects. Our model providesbehavioral explanations for the observed corporate cash holdings puzzle (i.e.,cash holdings may decrease or increase with the degree of ambiguity aversion).
