We consider asymmetric kernel density estimators and smoothed histogramswhen the unknown probability density function f is defined on [0, +∞). Uniform weak consistency on each compact set in [0, +∞) is proved for these estimators when "f" is continuous on its support. Weak convergence in L...

We study the asymptotic properties of a Tikhonov Regularized (TiR) estimator of a functional parameter based on a minimum distance principle for nonparametric conditional moment restrictions. The estimator is computationally tractable and takes a closed form in the linear case. We derive its...

Macroeconomic time series often involve a threshold effect in their ARMA representation, and exhibit long memory features. In this paper we introduce a new class of threshold ARFIMA models to account for this. The threshold effect is introduced in the autoregressive and/or fractional integration...

We present explicit formulae allowing us to price compound and exchange options in the framework of the affine term structure model. The various proposed options deal with discount bonds, coupon bonds and yields. A probabilistic approach is adopted in order to find closed-form pricing formulae....

Das Ziel des aktiven Portfoliomanagements ist es, eine bessere Performance als eine ex-ante definierte Benchmark zu erzielen. Die amerikanischen Aktienfonds sind zu 90% aktiv gemanagt und halten insgesamt 25% der Aktien in Amerika. Wegen des hohen Anteils gehaltener Aktien am Gesamtmarkt ist es...

This paper introduces a general framework for market models, named Market Model Approach, through the concept of admissible sets of for-ward swap rates spanning a given tenor structure. We relate this concept to results in graph theory by showing that a set is admissible if and only if the...

We propose new closed-form pricing formulas for interest rate options which guarantee perfect compatibility with volatility smiles. These cap pricing formulas are computed under variance optimal measures in the framework of the market model or the Gaussian model and achieve an exact calibration...

Two extensions of a parametric model are proposed, each one involving the score function of an alternative parametric model. We show that the encompassing hypothesis is equivalent to standard conditions on the score of each of the extended models.
