Kaizoji, Taisei - 2010

time series of each of these indices in the two periods: booms and stagnations, and investigate the statistical properties …The aim of this paper is to compare statistical properties of stock price indices in periods of booms with those in … periods of stagnations. We use the daily data of the four stock price indices in the major stock markets in the world: (i) the …

An econometric analysis of emission trading allowances

Paolella, Marc S. (contributor); Taschini, Luca (contributor) - 2006

World power and gas markets have a natural relationship with global tradable carbon permits markets, including the U.S. Clean Air Act Amendments and the EU Emissions Trading Scheme, the latter officially launched in January 2005. Electric utilities operate their power plants based in part on the...

A q-Weibull Autoregressive Conditional Duration Model with an Application to NYSE and HSE Data

Vuorenmaa, Tommi A. - 2011

This paper generalizes the ACD models of Engle and Russell (1998) using the so-called q-Weibull distribution as the conditional distribution. The new specification allows the hazard function to be non-monotonic. We document that the q-Weibull distribution recently suggested in physics as a...

Modelling Co-Movements and Tail Dependency in the International Stock Market Via Copulae

Ignatieva, Katja - 2012

This paper examines international equity market co-movements using time-varying copulae. We examine distributions from the class of Symmetric Generalized Hyperbolic (SGH) distributions for modelling univariate marginals of equity index returns. We show based on the goodness-of-fit testing that...

A Local Instrumental Variable Estimation Method for Generalized Additive Volatility Models

Kim, Woocheol - 2008

We investigate a new separable nonparametric model for time series, which includes many ARCH models and AR models already discussed in the literature. We also propose a new estimation procedure based on a localization of the econometric method of instrumental variables. Our method has...

Multifractality in Finance : A Deep Understanding and Review of Mandelbrot's MMAR

Maglione, Federico - 2015

Benoît Mandelbrot, the father of Fractal Geometry, developed a multifractal model for describing price changes. Despite the commonly used models, such as the Brownian motion, the Mutifractal Model of Asset Return (MMAR) takes into account scale-consistency, long-range dependence and heavy...

Dividend Growth Predictability and Stock Price Movement

Zhu, Min - 2016

This paper studies dividend growth predictability without restricting conditioning information set to dividend yield alone. We highlight that predictability crucially hinges on how dividend growth is constructed. Dividend growth without reinvestment is significantly predictable both in-sample...

Empirical evidences on the interconnectedness between sampling and asset returns' distributions

Orlando, Guiseppe; Bufalo, Michele - In: Risks : open access journal 9 (2021) 5, pp. 1-35

The aim of this work was to test how returns are distributed across multiple asset classes, markets and sampling frequency. We examine returns of swaps, equity and bond indices as well as the rescaling by their volatilities over different horizons (since inception to Q2-2020). Contrarily to some...

On Modelling Long Term Stock Returns with Ergodic Diffusion Processes : Arbitrage and Arbitrage-Free Specifications

Wong, Bernard - 2008

We investigate the arbitrage-free property of stock price models where the local martingale component is based on an ergodic diffusion with a specified stationary distribution. These models are particularly useful for insurer asset-liability management as they allow the modelling of long term...

A Note on Confidence Momentum and Term Structure of Confidence with Applications to Financial Markets

Charles-Cadogan, G. - 2012

This note is based on a recent confidence index introduced in the context of compensating probability factors for deviations of subjective probability measures from equivalent martingale measures. The index is adjusted for loss gain probability spreads, and it explains momentum in confidence. We...
