The paper derives a Multivariate Asymmetric Long Memory conditional volatility model with Exogenous Variables (X), or the MALMX model, with dynamic conditional correlations, appropriate regularity conditions, and associated asymptotic theory. This enables checking of internal consistency and...

In recent years fractionally differenced processes have received a great deal of attention due to its flexibility in financial applications with long memory. This paper considers a class of models generated by Gegenbauer polynomials, incorporating the long memory in stochastic volatility (SV)...

Diese Dissertation ist in drei Kapitel sowie eine Einleitung unterteilt. Die Einleitung führt in das Themengebiet ein, fasst die Kapitel zusammen und zeigt deren Zusammenhänge auf. Jedes Kapitel beschäftigt sich mit der Analyse von Finanzzeitreihen. Dabei wird insbesondere den „stylized...

This study documents the SNB's ARIMA model based on disaggregated CPI data used to produce inflation forecasts over the short-term horizon, and evaluates its forecasting performance. Our findings suggest that the disaggregate ARIMA model for the Swiss CPI performed better than relevant...
