In this paper, we extend the concept of News Impact Curve developed by Engle and Ng (1993) to the higher moments of the multivariate returns' distribution, thereby providing a tool to investigate the impact of shocks on the characteristics of the subsequent distribution. For this purpose, we...

There is a widespread belief that the US subprime mortgage crisis has escalated into a full-blown current global financial crisis and that many economies throughout the world have been hit by it. Using a test of financial market stability, this article shows the varying degree of impact...

This research aims to investigate, through simulation models, how the interaction among agents in an artificial stock market can affect the dynamics of asset prices. Thus, the study follows a different methodology for the analysis of prices by exploring the simulation of agents' behavior in an...

In this paper, we empirically analyze the effect of the credit crisis of 2008 by adopting coexceedance as a contagion measure. We assess the effect of news of governmental intervention and the collapse of firms during the period from 2007 to 2009 on the coexceedance. Our approach involves...

The transmission mechanisms of volatility between markets can be characterized within a new Markov Switching bivariate model where the state of one variable feeds into the transition probability of the state of the other. A number of model restrictions and hypotheses can be tested to stress the...

We estimate three continuous-time stochastic volatility models following the approach by Aït-Sahalia and Kimmel (2007) to compare the Korean and US stock markets. To do this, the Heston, GARCH, and CEV models are applied to the KOSPI 200 and S&P 500 Index. For the latent volatility variable, we...

Using a CCAPM-based risk-adjustment model, we perform yearly valuations of a large sample of stocks listed on NYSE, AMEX and NASDAQ over a thirty-year period. The model differs from standard valuation models in the sense that it adjusts forecasted residual income for risk in the numerator rather...

This paper examines the regime shifts and stock market volatility in the stock market returns of seven emerging economies popularly called as ‘BRIICKS' which stands for Brazil, Russia, India, Indonesia, China, South Korea and South Africa, over the period from February, 1996 to January, 2012...

We examine the ex-post performance of optimal portfolios with predictable returns, when the investor horizon ranges from one month to ten years. Due to the investor's ability to forecast shifts between bull and bear markets, predictability involves the risk premium, volatility and correlations,...

This paper introduces a new class of long memory model for volatility of stock returns, and applies the model on squared returns for BRICS (Brazil, Russia, India, China, and South Africa) countries. The conditional first- and second-order moments are provided. The CLS, FGLS and QML estimators...
