WebSep 25, 2024 · This study reports the relationship of working capital management (WCM) and corporate governance (CG) on firm performance (FP) using system generalized method of moments (SGMM). SGMM controls potential sources of endogeneity. This study uses US listed firms and includes two stages. WebJun 27, 2024 · Therefore, we can just just substitute the sample mean (moment) for population mean (moment) in the above simple solutions: ˆμ = 1 TΣxi ^ σ2 = 1 TΣ[xi − ˆμ]2. Now, we just obtain the estimators for μ and σ2 based on two moment conditions and the random samples. Usually we call such estimator as Method of Moments (MM) Estimator.
