Low Risk Anomaly in Banking Industry and Its Implications [Quantpedia]Traditional capital structure theory in frictionless and efficient markets predicts that reducing banks’ leverage reduces the risk and cost of equity but does not change the overall weighted average cost of capital (and thus the rates for borrowers).
