Using the copula capital structure model, it is shown that the correlation bias shifts shareholder preferences towards highly correlated assets, making financial institutions more prone to fail and increasing systemic risk given interconnectedness in the financial system. The implications for systemic risk and prudential regulation are assessed under the prism of Basel III, and potential solutions involving changes to the prudential framework and corporate governance are suggested UR - http://elibrary.imf.org/view/IMF001/11771-9781455226061/11771-9781455226061/11771-9781455226061.xml UR - http://www.imfbookstore.org/IMFORG/9781455226061 ER -
