This study investigates the impact of earnings management (EM) on the efficiency of Working Capital Management (WCM) and its components. The study uses M-Score, based on the Beneish Model, as a proxy for EM and applies generalized method of moments and panel quantile regression methods to a sample of 461 Indian-listed firms. We find that EM may inversely influence the WCM efficiency of Indian firms. Managers who engage in EM tend to operate on longer cash conversion cycle and manage inventory sub-optimally. These findings have been further confirmed by using an alternative EM proxy based on the Modified Jones Model.

盈余管理对营运资本管理效率的影响

本研究调查盈余管理 (EM) 对营运资本管理( WCM) 及其组成部分效率的影响。该研究使用基于 Beneish 模型的 M-Score 作为 EM 的代理，并将广义矩量法和面板分位数回归方法应用于 461 家印度上市公司的样本。我们发现 EM 可能会对印度公司的 WCM 效率产生负面影响。从事 EM 的经理往往会在较长的现金转换周期内运营，并且会以次优方式管理库存。这些发现已通过使用基于改进的琼斯模型的替代 EM 代理得到进一步证实。
