英文摘要:
Cash managers make daily decisions based on predicted monetary inflows from debtors and outflows to creditors. Usual assumptions on the statistical properties of daily net cash flow include normality, absence of correlation and stationarity. We provide a comprehensive study based on a real-world cash flow data set from small and medium companies, which is the most common type of companies in Europe. We also propose a new cross-validated test for time-series non-linearity showing that: (i) the usual assumption of normality, absence of correlation and stationarity hardly appear; (ii) non-linearity is often relevant for forecasting; and (iii) typical data transformations have little impact on linearity and normality. Our results provide a forecasting strategy for cash flow management which performs better than classical methods. This evidence may lead to consider a more data-driven approach such as time-series forecasting in an attempt to provide cash managers with expert systems in cash management.

中文摘要:
现金管理人根据预测的债务人资金流入和债权人资金流出做出日常决策。日常净现金流量统计特性的通常假设包括正态性、无相关性和平稳性。我们基于中小型公司(欧洲最常见的公司类型)的真实现金流数据集进行了全面研究。我们还提出了一种新的时间序列非线性交叉验证检验,表明:(i)通常的正态性、相关性和平稳性假设几乎不存在;(ii)非线性通常与预测相关;(iii)典型的数据转换对线性和正态性的影响很小。我们的结果为现金流管理提供了一种预测策略,其性能优于经典方法。这一证据可能导致考虑一种更为数据驱动的方法,如时间序列预测,试图为现金经理提供现金管理方面的专家系统。
