In this paper, robust M-estimation of multivariate GARCH models are considered. The simplified GARCH model is chosen that involves the estimation of only univariate GARCH models, and hence easy to estimate, and does not put additional constraints on the model. The results of Monte Carlo...

This article examines the impact of a bidding firm's geographical location on the choice of method of payment in mergers and acquisitions. We find that rural bidders are more likely to offer pure stock deals and have lower propensity to use cash as the method of payment compared to their...

This article examines the extent to which the trading behavior of heterogeneous investors manifests in stock price changes of asset portfolios which constitute the Shanghai Stock Exchange. There are three major findings that materialize. Firstly, reliable statistical evidence of a negative...

This paper extends the intertemporal capital asset pricing model (ICAPM) to integrate the heterogeneous trading behavior of three groups of investors; rational utility maximizers, positive feedback, or momentum, traders, and fundamental traders. Using several contemporary fundamental factors to...

This paper examines the time-varying behaviour of beta risk and degree of volatility persistence in the daily stock returns of 30 industry portfolios consisting of firms from the NYSE, AMEX and NASDAQ stock exchanges. Using an exponential ARCH (EGARCH) for this purpose, it further examines the...
