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...

We study Tikhonov Regularized estimation of quantile structural effects implied by a nonseparable model. The nonparametric instrumental variable estimator is based on a minimum distance principle. We show that the minimum distance problem without regularization is locally ill-posed, and consider...

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...

Macroeconomic time series often involve a threshold effect in theirARMA representation, and exhibit long memory features. In this paperwe introduce a new class of threshold ARFIMA models to account forthis. The threshold effect is introduced in the autoregressive and/or thefractional integration...

This paper investigates some common determinants of default probability changes ofindividual firms using Standard & Poor's ratings database. We analyze and quantify the re-sponses of hazard rates to changes in various economic variables, namely financial markets,business cycle and credit...

This paper publishes results on the convergence for hedging strategies in the setting of incomplete financial markets.

This paper delevops a tools to analyse the ordering of concordance of random vectors.

This papfer deals with distributional free inference to test for positive quadrant dependence, i.e. for the probability that two variables are simultaneously small (or large) being at least as great as it would be were they dependent.

This paper considers the option pricing when dynamic portfolios are discretely rebalanced.

This paper shows optimal asset allocation during these two phases must be different.
