An analysis of systematic risk in worldwide econonomic sentiment indices

Luu, Duc Thi; Yanovski, Boyan; Lux, Thomas - 2018 - Ver. January 2, 2018

tools of Random Matrix Theory (RMT) and Principal Component Analysis (PCA), our paper aims to extract latent information … embedded in the interactions between economic and business sentiment indices around the world. We find that: (i) The dynamics … collapse of the US housing market in 2007, can lead to a homogenization of the expectation structure around the world, as such …

The Markov-Switching Multifractal Model of asset returns : GMM estimation and linear forecasting of volatility

Lux, Thomas (contributor) - 2006

Multifractal processes have recently been proposed as a new formalism for modelling the time series of returns in finance. The major attraction of these processes is their ability to generate various degrees of long memory in different powers of returns - a feature that has been found in...

The Markov-switching multi-fractal model of asset returns : GMM estimation and linear forecasting of volatility

Stochastic behavioral asset pricing models and the stylized facts

Lux, Thomas (contributor) - 2008

High-frequency financial data are characterized by a set of ubiquitous statistical properties that prevail with surprising uniformity. While these 'stylized facts' have been well-known for decades, attempts at their behavioral explanation have remained scarce. However, recently a new branch of...

Multifractality and long-range dependence of asset returns : the scaling behaviour of the Markov-switching multifractal model with lognormal volatility components

Liu, Ruipeng (contributor); Di Matteo, Tiziana (contributor) - 2008

In this paper we consider daily financial data from various sources (stock market indices, foreign exchange rates and bonds) and analyze their multi-scaling properties by estimating the parameters of a Markov-switching multifractal model (MSM) with Lognormal volatility components. In order to...

Inference for nonlinear state space models : a comparison of different methods applied to Markov-switching multifractal models

Lux, Thomas - 2018

Nonlinear, non-Gaussian state space models have found wide applications in many areas. Since such models usually do not allow for an analytical representation of their likelihood function, sequential Monte Carlo or particle filter methods are mostly applied to estimate their parameters. Since...

On the distribution of links in financial networks : structural heterogeneity and functional form

Lux, Thomas - 2017

We investigate the distribution of links in three large data-sets, one of these covering interbank loans in the electronic trading platform e-MID, the other two covering a large part of the loans of banks to non-financial companies in the Spanish and Japanese economies, respectively. In contrast...

Lack of identification of parameters in a simple behavioral macroeconomic model

Lux, Thomas - 2024

Identifiability of the parameters is an important precondition for consistent estimation of models designed to describe empirical phenomena. Nevertheless, many estimation exercises proceed without a preliminary investigation into the identifiability of its models. As a consequence, the estimates...
