Two of the fastest growing frontiers in econometrics and quantitative finance are time series and financial econometrics. Significant theoretical contributions to financial econometrics have been made by experts in statistics, econometrics, mathematics, and time series analysis. The purpose of...

In this paper, we study the asymptotic behavior of the sequential empirical process and the sequential empirical copula process, both constructed from residuals of multivariate stochastic volatility models. Applications for the detection of structural changes and specification tests of the...

Mit dem angedachten Solvabilitätssystem Solvency II werden Versicherer das erforderliche Solvenzkapital anhand ihrer tatsächlichen Risikosituation ermitteln müssen. Um diese zu bestimmen und zu quantifizieren, ist die Berücksichtigung der Abhängigkeiten zwischen den Risiken verschiedener...

In this selective review, we first provide some empirical examples that motivate the usefulness of semi-nonparametric techniques in modelling economic and financial time series. We describe popular classes of semi-nonparametric dynamic models and some temporal dependence properties. We then...

The current paper focuses on analyzing and modeling the physical activity participation levels (in terms of the number of daily bouts or episodes of physical activity during a weekend day) of all members of a family jointly. Essentially, we consider a family as a cluster of individuals whose...

Olive oil yields fluctuate strongly due to their dependence on sufficient precipitation. An interesting option to hedge the yield risk in olive cultivation could be satellite-based weather index insurance. Therefore, we implement index insurance as a hedging alternative for non-irrigated olive...

This paper investigates whether multivariate crash risk (MCRASH), defined as exposure to extreme realizations of multiple systematic factors, is priced in the cross-section of expected stock returns. We derive an extended linear model with a positive premium for MCRASH and we empirically confirm...
