This study examines whether share pledging by controlling shareholders improves investment efficiency in India. Using a panel of 1,167 listed firms from 2009 to 2023, we find that pledging improves investment efficiency by simultaneously reducing overinvestment (12.41%) and underinvestment (3.62%), effects confirmed through channel analyses showing that creditor monitoring drives the overinvestment reduction, while financing access drives the underinvestment reduction. These effects are stronger in financially constrained and group-affiliated firms. Findings are robust to alternative constraint proxies, including the size–age index and size tercile, an augmented investment model, propensity score matching, and Oster omitted variable bias bounds.
