In this study, we apply a new recursive test proposed by Philips et al (2013) to investigate whether there exist multiple bubbles in the BRICS (Brazil, Russia, India, China and South Africa) stock markets, using monthly data on stock price-dividend ratio. Our empirical results, the first of its...

The aim of this paper is to study the degree of interdependence between oil price and stock market index into two groups of countries: oil-importer countries and exporter ones. To this end, we propose a new empirical methodology allowing a time-varying dynamic correlation measure between the...

This paper assesses the impact of oil prices on economic growth of the four major OPEC countries (United Arab Emirates, Kuwait, Saudi Arabia and Venezuela) over the period spanning from 03/09/2000 to 03/12/2010. We aim at complementing the results from existing analyses (mainly focused on...

We combine the global Hurst exponent and Morlet wavelet multi-resolution analysis to investigate the dynamic behavior of six selected stock markets in the Mediterranean region. Specifically, we employ the resonance coefficients and their power spectra to identify potential extreme movements and...

This paper constructs a robust optimization framework of the uncertain worst-case return. The model defines an adjustable discrete uncertainty set which controls the conservatism of the optimal asset allocation. Without prior assumptions on the data generating process, the model also develops an...

In this paper we examine the degree of interdependence between oil prices and four major countries (United

The aim of this paper is to study the degree of interdependence between oil price and stock market

We analyze the reactions of the returns of four European stock markets to sovereign credit rating changes by Fitch, Moody’s, and Standard and Poor’s (S&P) during the period from June 2008 to June 2012 using panel regression equations. We find that (i) upgrades and downgrades affect both own...

This paper examines the dependence structure between the emerging stock markets of the BRICS countries (Brazil, Russia, India, China and South Africa) and influential global factors (the S&P 500 index, the commodity markets, the global stock market uncertainty and the US economic policy...

The paper employs an event study methodology to investigate the macroeconomic announcements effects on S&P500 and oil prices. Our results provide evidence of a significant impact of the US macroeconomic news on oil prices. This impact is split into two components, namely the direct effect...
