Purpose The purpose of this paper is to examine the relationship between working capital management and firm performance for a sample of 437 non-financial Indian companies. In addition, this paper examines the impact of financial constraints on working capital management-performance relationship. Design/methodology/approach This study is based on secondary financial data of 437 non-financial Indian companies obtained from CAPITALINE database, pertaining to a period of ten years. This study employs the two-step generalized method of moments (GMM) technique to arrive at results. Findings Results of the study confirm the inverted U-shape relationship between working capital management and firm performance. In addition, the authors also found that the firms that are likely to be more financially constrained have lower optimal working levels. Originality/value Unlike prior studies, which found a linear relationship between working capital management and firm performance, this study provides newer evidence for an inverted U-shaped relation between investment in working capital and firm performance in India. In addition, this study also tests the impact of financial constraints on this relationship. In contrast to the prior studies, this study uses GMM to control the potential problems of endogeneity.
