This paper examines causality between the series of returns ans transaction volumes in high frequency data. The dynamics in both series is restricted to transitions between a finite umber of stated. Depending on the state selection criteria, this approach approximated the dynamics of varying...

The successful investment policy is an integral part of successful activity of the insurance company. The return to the shareholders of the insurance company usually thought of as comprising the underwriting result and investment income. The investment income is very important even for an...

The relationships between monetary/financial variables have highly drawn attention in the literature using different techniques so as to observe whether the underlying theoretical mechanisms are compatible with the facts. In this study the scope is to investigate the relationship between...

Measuring the dynamic relationship between banking and industries with systemic importance has attracted much attention after the recent financial crisis. This paper examines the dynamic conditional correlations and volatility spillover using three popular multivariate GARCH models in the...

Structural breaks in GARCH processes do matter for applications and model-based inference. To show this, I first propose a new approach to estimate change-point GARCH models with maximum likelihood, for which no method exists so far. Practical implementation of the proposed algorithm is...

This paper analyzes the implications of autoregressive betas in single factor models for the statistical properties of stock returns. It is demonstrated that this assumption alone is sufficient to account for the most important stylized facts of stock returns, namely conditional...

The risk return relationship is analysed in bivariate models for return and realised variance (RV) series. Based on daily time series from 21 international market indices for more than 13 years (January 2000 to February 2013), the empirical findings support the arguments of risk return tradeoff,...

This study tests the validity of asset pricing model conditional on up and down market for emerging market of Pakistan. The results indicate that when emerging market undergoes negative market excess return, basic capital asset pricing model is inaccurate to predict stock returns. Although the...

Classical quantitative finance models such as the Geometric Brownian Motion or its later extensions such as local or stochastic volatility models do not make sense when seen from a physics-based perspective, as they are all equivalent to a negative mass oscillator with a noise. This paper...
