Identifying market crashes can be problematic. In a stable financial environment, the same price variation in percentage will result in greater negative impact than during a highly volatile period.In order to take into account changes of volatility throughout time, a new method is proposed, one...

Les krachs boursiers sont décisifs car ils représentent une part importante de la valeur finale d'un indice boursier. Mais, une variation d'un pourcentage identique n'a pas le même impact dans un environnement financier préalablement stable ou hautement volatile. Pour appréhender les krachs...

A healthy financial system encourages the efficient allocation of capital and risk. The collapse of the house price bubble led to the financial crisis that started in 2007. There is a large empirical literature concerning the relation between asset price bubbles and financial crises. I evaluate...

The 'shadow banking system' at the heart of the current credit crisis is, in fact, a real banking system – and is vulnerable to a banking panic. Indeed, the events starting in August 2007 are a banking panic. A banking panic is a systemic event because the banking system cannot honor its...

This interdisciplinary paper explains how mathematical techniques of stochastic optimal control can be applied to the recent subprime mortgage crisis. Why did the financial markets fail to anticipate the recent debt crisis, despite the large literature in mathematical finance concerning optimal...

We estimate a highly significant price of risk that forecasts global stock and bond returns as a nonlinear function of the CBOE Volatility Index (VIX). We show that countries' exposure to the global price of risk is related to macroeconomic risks as measured by output, credit, and inflation...

Using novel data on investors' bond portfolios, we study the contagion of the crisis from securitized bonds to corporate bonds. When securitized bonds became “toxic” in August 2007, mutual funds retained the now illiquid securitized bonds and sold corporate bonds. Funds with negative flows...

In pricing real estate with indifference pricing approach, market incompleteness is shown to significantly alter the conventional pricing relationships between real estate and financial asset. Specifically, we focus on the pricing implication of market comovement because comovement tends to be...

In pricing real estate with indifference pricing approach, market incompleteness significantly distorts the conventional pricing relationships between real estate and financial asset. In this paper, we focus on the pricing implication of market comovement because comovement tends to be stronger...

This paper studies whether the choice of the crisis start dates affects the magnitude of contagion estimates. Contagion models generally use exogenously determined crisis start date by relying on event-based markers. We conduct structural break tests and endogenously determine the start dates of...
