This study applies a partial‐adjustment model to test how well trade‐off theory explains net working capital management decisions and examines working capital management dynamics. The results indicate that firms have long‐run NWC targets and tend to gradually converge to the target from the firm's initial net working capital level within each period. We estimate that typical firms close approximately 50% of the gap between their actual and target net working capital each year. Such high adjustment speed implies that a typical firm closes half of a deviation from the target in about 13 months. Our results show that the trade‐off theory can explain the management decisions regarding working capital holdings.
