We develop a model of the joint capital structure decisions of banks and their borrowers. Strikingly high bank leverage emerges naturally from the interplay between two sets of forces. First, seniority and diversification reduce bank asset volatility by an order of magnitude relative to that of...

Bilateral derivatives valuation is subject to counterparty credit risk (CCR) in that a counterparty could jump to default or its credit spread could vary over time. In the nomenclature of risk management, the former is called CCR exposure and the later leads to credit valuation adjustment (CVA)....

Flexibility theory of capital structure, credit rationing, and stage-financing theory are consistent with many patterns of financing of entrepreneurial or small/medium size enterprises (SME). Tax theory of capital structure does not seem to play a significant role for SMEs as opposite to large...

After the 2008 financial crisis, policymakers focused on enacting improvements in two areas of financial regulation: capital and liquidity, affecting the composition of bank assets and the sources of bank funding. These improvements made both the emergence of a crisis less likely and the...

Accurate Value at Risk (VaR) estimations are crucial for the robustness and stability of a financial system. Even though significant advances have been made in the field of risk modelling, many crises have emerged during the same period, and an explanation for this is that the advanced models...

This paper investigates regulations for a bank that is covered by deposit insurance in a dynamic setting where bankruptcy entails social costs. Regulatory policy operates through rules governing the bank's capital structure and asset allocation that may be adjusted each period. Throughout, the...

Traditional capital structure theory predicts that reducing banks' leverage reduces the risk and cost of equity but does not change the weighted average cost of capital, and thus the rates for borrowers. We confirm that the equity of better-capitalized banks has lower beta and idiosyncratic...

Deleveraging has two components -- shrinking of balance sheets due to increased haircuts/shedding of assets, and the reduction in the interconnectedness of the financial system. We focus on the second aspect and show that post-Lehman there has been a significant decline in the interconnectedness...

Financial lubrication in markets is indifferent to margin posting via money or collateral; the relative price(s) of money and collateral matter. Some central banks are now a major player in the collateral markets. Analogous to a coiled spring, the larger the quantitative easing(QE) efforts, the...

VaR_Delta-Normal fails in two counts: subadditivity and potentially producing losses larger than its portfolio value. This paper solves the second inconsistency developing formulas derived from a put option, named PVaR_Delta-Normal and Put_Expected_Shortfall, PSF_Delta-Normal; the latter also...
