Personal bankruptcy costs, union bargaining power, and capital structure

We document that employee bankruptcy costs affect corporate capital structure decisions via their impact on the bargaining power of labor unions. We employ difference-in-differences and triple-difference research designs surrounding a major bankruptcy reform that increased personal bankruptcy costs. Our results suggest that, on average, this reform reduced unions' bargaining power, resulting in a decrease in the financial leverage of unionized firms relative to nonunionized firms. Our results provide new evidence for a relatively unexplored determinant of capital structure-personal bankruptcy costs.
