This paper aims at contributing to the international portfolio investment decisions among the emerging BRICS countries where individual and institutional investors seek diversification benefits and to help in advocating policy changes and implementation as a response to the changing dynamics in...

This paper formally implements time-varying risk price models for currency returns. Focusing upon time variation in risk prices, the paper explores four currency risk factors. In addition to dollar and carry factors, we employ momentum and value factors which are widely used by currency...

Although several types of options on multiple assets are popular in today's financial markets, valuing multi-asset options is still a challenge in finance. The standard framework of multivariate normality is often inappropriate, since it ignores fat tails and other stylized facts of asset...

This paper proposes a new mutual exciting regime-switching model where crises can spread contagiously across countries. Each country has its own hidden stochastic process that determines whether it is in a normal or crisis regime. The mutual-excitation component allows interactions in the Markov...

This study uses the Multiplicative Error Model (MEM) to explore asymmetric volatility spillovers between crude oil and other major asset markets. We have extended the MEM of Engle et al. (2012) and ddd to include asymmetric volatility spillovers and developed the spillover balance as well as...

We study risk-return relationship in twenty Frontier country stock markets by setting up an international version of the intertemporal capital asset pricing model (International ICAPM). The systematic risk in this model comes from covariance of Frontier market stock index returns with world...

We study alternative specifications of conditional quantile models that are used to estimate Value at Risk (VaR). Our proposed specifications include the incorporation of a slow moving component in the quantile process, along with recent aggregate returns as regressors. We consider a range of...

A long criticism on the usefulness of the traditional CAPM model has been raised in the vast literature of arbitrage pricing models that propose several risk factors on firm fundamentals or investigate the stochastic properties of stock returns' distributions, (Fama and French (2004)). However,...
