This paper characterizes the probability of a market failure defined as the default of two or more globally systemically important banks (G-SIBs) in a small interval of time. The default probabilities of the G-SIBs are correlated through the possible existence of a market-wide stress event. The...

This paper derives a generalized multiple-factor asset pricing model using only the assumptions of the existence of an equivalent martingale measure, frictionless, and competitive markets. As such, all existing multiple-factor asset pricing models, including the intertermporal CAPM and Ross'...

This paper shows that high frequency trading may play a dysfunctional role in financial markets. Contrary to arbitrageurs who make financial markets more efficient by taking advantage of and thereby eliminating mispricings, high frequency traders can create a mispricing that they unknowingly...

This paper provides asymptotic valuation formulas for credit derivatives on baskets, including synthetic and cash flow CDOs. As such, it provides the link between the "bottom up" and "top down" approaches used for the pricing of these credit risky securities

Jensen's alpha is well-known to be a measure of abnormal performance in the evaluation of securities and portfolios where abnormal performance is defined to be an expected return that exceeds the equilibrium risk adjusted rate. It is also well known that in estimating Jensen's alpha, a non-zero...

This paper studies asset price bubbles in a continuous time model using the local martingale framework. Providing careful definitions of the asset's market and fundamental price, we characterize all possible price bubbles in an incomplete market satisfying the "no free lunch with vanishing risk...

This paper develops a new model for studying foreign currency exchange rate bubbles. The model constructed is a modification of the Martingale-based bubble approach of Jarrow, Protter, and Shimbo [12], [13]. This model generates some new insights into our understanding of exchange rate bubbles...

Jensen's alpha is well-known to be a measure of abnormal performance in the evaluation of securities and portfolios where abnormal performance is defined to be an expected return that exceeds the equilibrium risk adjusted rate. It is also well known that in estimating Jensen's alpha, a non-zero...

Consider a d-dimensional Brownian motion X (Xl, ... ,Xd ) and a function F which belongs locally to the Sobolev space W 1,2. We prove an extension of Ito's formula where the usual second order terms are replaced by the quadratic covariations [fk(X), Xkj involving the weak first partial...
