Understanding Cash Flow Risk
利用新方法估计企业面临的短期和长期现金流冲击参数，发现这些参数与企业的流动性、融资决策及现金持有行为密切相关。
Abstract Theory has recently shown that corporate policies should depend on firms’ exposure to short- and long-lived cash flow shocks and the correlation between these shocks. We provide granular estimates of these parameters for Compustat firms using a new filter that uses only cash flow data and the theoretical restrictions of a canonical cash flow model. As predicted by theory, we find that the estimated parameters are strongly related to corporate liquidity and financing choices, that firms with a higher estimated correlation between shocks implement riskier policies, and that the sign of this correlation determines the cash flow sensitivity of cash. Authors have furnished an Internet Appendix, which is available on the Oxford University Press Web site next to the link to the final published paper online.
