We study the robustness of block resampling procedures for time series. We first derive a setof formulas to quantify their quantile breakdown point. For the block bootstrap and the sub-sampling, we find a very low quantile breakdown point. A similar robustness problem arisesin relation to...

In this paper, we consider the coherent theory of (epistemic) uncertainty ofWalley, in whichbeliefs are represented through sets of probability distributions, and we focus on the problemof modeling prior ignorance about a categorical random variable. In this setting, it isa known result that a...

We develop a new completely affine model of the term structure of interest rates, in which the statevariables evolve as a matrix-valued process of stochastically correlated factors. This setting grants a newelement of flexibility in the simultaneous modeling of stochastic volatilities and...

We develop infinitesimally robust statistical procedures for general diffusion pro-cesses. We first prove existence and uniqueness of the times series influence functionof conditionally unbiased M{estimators for ergodic and stationary diffusions, underweak conditions on the (martingale)...

This paper studies the asset pricing implications of a general equi-librium model in which real investment is reversible at a cost. Firmsface higher costs in contracting than in expanding their capital stockand decide to invest when their productive capital is scarce relativeto the overall...

Filtrations have been introduced by Doob and have been a fundamentalfeature of the theory of stochastic processes. Most basic objects, such asmartingales, semimartingales, stopping times or Markov processes involvethe notion of filtration.[...]

This paper studies the Cass-Koopmans-Ramsey model of optimal economic growth with a representative agent whose preferences for consumption can be gradually varied between the standard CES case and Kahneman and Tversky's prospect utility. The numerical analysis of a specific parametrization shows...

Two experiments investigated impacts of hazard types and information deliveries on riskperception, with a focus on the role of emotions. In the first experiment, technologicalhazards aroused stronger emotions, and were considered as riskier than natural hazards. Nodifferences were found between...

The use of different currencies in the invoicing of international trade transactions plays a major role in the international transmission of economic fluctuations. Existing studies argue that an exporter’s invoicing choice reflects structural aspects of her industry, such as market share and...

We study a quadratic BSDE in a continuous filtration with an unbounded generatorand an infinite time horizon. This equation comes from a stochasticcontrol problem in the context of robust utility maximisation.[...]
