On the short-term influence of oil price changes on stock markets in GCC countries: linear and nonlinear analyses

This paper examines the short-run relationships between oil prices and GCC stock markets. Since GCC countries are major world energy market players, their stock markets may be susceptible to oil price shocks. To account for the fact that stock markets may respond nonlinearly to oil price shocks, we have examined both linear and nonlinear relationships. Our findings show that there are significant links between the two variables in Qatar, Oman, and UAE. Thus, stock markets in these countries react positively to oil price increases. For Bahrain, Kuwait, and Saudi Arabia we found that oil price changes do not affect stock market returns.

A la Recherche des Facteurs Déterminants de l'Intégration Internationale des Marchés Boursiers : une Analyse sur Données de Panel

The aim of this paper is to identify the determinants of international stock markets integration. Intuitively we selected a great number of factors linked to financial integration. Then, we developed an international asset-pricing model with time-varying degree of integration. This model is estimated for 30 countries (10 developed countries and 20 emerging countries) using panel data econometrics. In order to investigate whether the financial integration in emerging markets and that in developed markets react differently to the economic and financial innovations, we estimated the model as well jointly for all markets as separately for developed markets and emerging markets. Our results show that trade openness exerts a positive effect on financial integration across all markets, the global factors drive integration in developed markets whereas the factors related to economic and political stability affect financial integration in emerging markets.

Structural Breaks in the Mexico's Integration into the World Stock Market

This article investigates the evolution of the Mexican stock market integration into the world market. First, we estimate the time-varying Mexican degree of market integration using an international conditional version of the CAPM with segmentation effects. Second, we study the structural breaks in this series. Finally, we relate the obtained results to important facts and economic events

Stock market integration in the Latin American markets: further evidence from nonlinear modeling

This article studies the financial integration between the six main Latin American markets and the US market in a nonlinear framework. Using the threshold cointegration techniques of Hansen and Seo (2002), we show significant threshold stock market linkages between Mexico, Chile and the US. Thus, the dynamics of these markets depends simultaneously on local and global risk factors. More importantly, our results show an on-off threshold financial integration process that is activated only when the stock price adjustment exceeds some level.

Are Stock Markets Integrated? Evidence from a Partially Segmented ICAPM with Asymmetric Effects

In this paper, we test a partially segmented ICAPM for two developed markets, two emerging markets and World market, using an asymmetric extension of the multivariate GARCH process of De Santis and Gerard (1997,1998). We find that this asymmetric process provides a significantly better fit of the data than a standard symmetric process. The evidence obtained from the whole period and sub-periods analysis supports the financial integration hypothesis and suggests that domestic risk is not a priced factor.

La prime de risque dans un cadre international : le risque de change est-il apprécié ?

In this article, we investigate whether exchange rate risk is priced. We use a multivariate GARCH-in-Mean specification and test alternative conditional international CAPM versions. Our results support strongly the international asset-pricing model that includes exchange rate risk for both developed and emerging stock markets. However, there are important time and cross-country variations in the relative size and dynamics of different risk premia.
