We present a simple theory of business-cycle movements of option prices and volumes. This theory relies on time-varying heterogeneity between agents in their demand for insurance against aggregate risk. Formally, we build an infinite-horizon model where agents face an aggregate risk, but also...

The purpose of this paper is to propose discrete-time term structure models where the historical dynamics of the factor (xt) is given, in the univariate case, by a Gaussian AR(p) process, and, in the multivariate case, by a Gaussian n-dimensional VAR(p) process. The factor (xt) is considered as...

We consider the problems of derivative pricing and inference when the stochastic discount factor has an exponential-affine form and the geometric return of the underlying asset has a dynamics characterized by a mixture of conditionally Normal processes. We consider both the static case in which...

We study the liquidity allocation among European banks around the Lehman Brothers’ insolvency using a novel dataset of all interbank loans settled via the Eurosystem’s payment system TARGET2. Following the Lehman insolvency, lenders in the overnight segment become sensitive to counterparty...

Speculators can discover whether a signal is true or false by processing it but this takes time. Hence they face a trade-off between trading fast on a signal (i.e., before processing it), at the risk of trading on a false news, or trading after processing the signal, at the risk that prices...

This paper introduces a novel kind of interest-rate model offering simple analytical pricing formulas for swaps, futures, swaptions, caps and floors. The model is based on an original use of regime-switching features that makes it consistent with the non-linear behavior of interest rates. In...

- Contrairement au marché américain, le marché de la titrisation européenne ne s’est pas totalement effondré avec la crise financière de 2008, même s’il a connu depuis une certaine atonie. La plus grande attention désormais apportée à la qualité des actifs sous-jacents a permis un...

Aggregate consumption growth risk explains why low interest rate currencies do not appreciate as much as the interest rate differential and why high interest rate currencies do not depreciate as much as the interest rate differential. Domestic investors earn negative excess returns on low...

We measure the commonality in hedge fund returns, identify its main driving factor and analyze its implications for financial stability. We find that hedge funds’ commonality increased significantly from 2003 until 2006. We attribute this rise mainly to the increase in hedge funds’ exposure...

A large part of the term structure literature interprets the first underlying factors as a level factor, a slope factor, and a curvature factor. In this paper we consider factor models interpretable as a level factor model, a level and a slope factor model, respectively. We prove that such...
