Cost behaviour and reporting frequency during the COVID-19 outbreak
研究了财务报告频率（季度 vs 半年）如何影响企业在危机中的成本管理决策，发现季度报告者成本弹性更大，在销售下降时削减成本更多，且短期业绩更好。
We examine the effect of financial reporting frequency on cost management decisions in crisis situations, with a focus on the COVID-19 outbreak.Using the European setting, we find that quarterly reporters exhibit greater cost elasticity relative to semi-annual reporters, meaning they had larger changes in cost for each change in sales.When allowing for cost asymmetry, we see that our results are driven by firms with decreases in sales and that quarterly reporters reduced their costs more.Additional analyses show that managerial learning and monitoring pressure might be potential channels behind the results and that there is a positive performance effect in the short run.
