Empirical Capital Structure: A Review

This survey provides a synthesis of the empirical capital structure literature. Our synthesis is divided into three parts. The first part examines the evidence that relates to the cross-sectional determinants of capital structure. This literature identifies and discusses the characteristics of firms that tend to be associated with different debt ratios. In the second part, we review the literature that examines changes in capital structure. The papers in this literature explore factors that move firms away from their target capital structures as well as the extent to which future financing choices move firms back toward their targets. Finally, we complete our review with a set of studies that explore the <italic>consequences</italic> of leverage, rather than its determinants. These studies are concerned with feedback from financing to real decisions. For example, we explore how a firm's financing choices influences its incentive to invest in its workers, price its products, form relationships with suppliers, or compete aggressively with competitors.
