Seasonal variation in cash flows and the timing role of accruals
研究了应计项目在抵消季度现金流波动中的重要作用，发现其时间调节作用比基于年度数据得出的结论更强，并分析了该作用随时间下降的原因。
This paper examines the function of accruals in measuring quarterly firm performance. We show that operating accruals play a pronounced role in offsetting quarterly cash flow fluctuations and that this timing role is much stronger than concluded based on annual measurements in the recent literature. A fundamental driver of this timing role of accruals is the significant seasonal variation in operating cash flows, which is determined by the interaction between sales seasonality and working capital policies. We further find that the seasonality in cash flows and the offsetting role of accruals have declined over time. We link this trend to international diversification, trends in the importance and seasonality of retail sales, zero-inventory firms, market power, and the rise in supply chain finance.
