This article presents a comprehensive framework for valuing financial instruments subject to credit risk and collateralization. In particular, we focus on the impact of default dependence on asset pricing, as correlated default risk is one of the most pervasive threats to financial markets. Some...

Banks hold liquid and illiquid assets. An illiquid bank that receives a liquidity shock sells assets to liquid banks in exchange for cash. We characterize the constrained efficient allocation as the solution to a planner's problem and show that the market equilibrium is constrained inefficient,...

We take issue with claims that the funding mix of banks, which makes them fragile and crisis-prone, is efficient because it reflects special liquidity benefits of bank debt. Even aside from neglecting the systemic damage to the economy that banks' distress and default cause, such claims are...

Dividend payouts affect the relative value of claims within a firm. When firms have contingent claims on each other, as in the banking sector, dividend payouts can shift the relative value of stakeholders' claims across firms. Through this channel, one bank's capital policy affects the equity...

This article presents a generic model for pricing financial derivatives subject to counterparty credit risk. Both unilateral and bilateral types of credit risks are considered. Our study shows that credit risk should be modeled as American style options in most cases, which require a backward...

VaR remains important in market risk management as Basel keeps most of the backtesting based on 1% VaR. Comparative backtesting as practiced in the current literature suffers from a major double problem. On the one hand, the score functions, although strictly consistent, may assign very good or...

Under a "mea culpa" framework, evidence suggests that financial institutions practice discretionary hedging of both interest rate and funding risks, unlike Silicon Valley Bank and First Republic Bank. Banks asymmetrically manage risk by intensifying hedging with interest rate derivatives as HTM...

Arbitrage trading strategies are a class of trading strategies that involve buying and selling financial instruments to take advantage of price discrepancies. The goal of arbitrage trading is to make a profit from the differences in prices between securities or markets, without taking on...
