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,...

This paper studies the Mexican stock market integration process. First, we estimate the time-varying Mexican degree of market integration using an international CAPM with segmentation effects. Second, we study the structural breaks in this series. Finally, we relate the obtained results to...

This paper assesses the macroeconomic impact of fiscal policy shocks for four key emerging market economies – Brazil, Russia, India and China (BRICs) – using a fully simultaneous system of equations. We also estimate fiscal policy rules and analyze the importance of nonlinearity using a...

This article aims at checking whether the macroeconomic models of consumption are always verified to reproduce the dynamics of consumption habits. We show that even if the Keynesian theory of consumption is still checked as the disposable income is a significant explanatory variable of household...

Although the assumption in the financial press is that fluctuations in the price of oil affect stock market prices, empirical evidence of the impact of these fluctuations on stock returns has been mixed. Unlike other empirical studies, which have focused largely on broad market indices (national...

The aim of this paper is to study the efficient capital market hypothesis by using recent developments in nonlinear econometrics. In such a context, we estimate a Smooth Transition Error Correction Model (STECM). We introduce the DowJones as an explanatory variable of the dynamics of the other...

This article aims at checking whether the macroeconomic models of consumption are always verified to reproduce the dynamics of consumption habits. We show that even if the Keynesian theory of consumption is still checked as the disposable income is a significant explanatory variable of household...

This paper studies volatility dynamics and provides further insights into its relationship with trading volume. In particular, we examine whether trading volume is significantly informative for investors when attempting to apprehend potential changes in volatility dynamics, and hence, in the...
