This study examines crude oil prices throughout the world, as well significant stock returns of European importers and exporters (the UK, Germany, France, Italy, Switzerland, Netherlands) (Norway Russia). Indexes sustainability stocks have a greater correlation with countries that import than those export oil. There was stronger between both during after global financial meltdown in 2008. Study...

The aim of this paper is to find economic factors that could be helpful in explaining the market’s shifts between periods prosperity and crisis. study took into account main stock indices from developed markets USA, Germany Great Britain, two emerging markets, i.e. Poland Turkey. analysis confirms existence different states volatility these namely state with a positive returns’ mean low volatil...

This paper studies transmission of international energy price shocks to various sectors in the Australian stock market. We take the multivariate generalized autoregressive conditional heteroscedasticity (MGARCH) approach to modeling volatility and gather evidence that energy price shocks transmit to the price indices of various sectors classified by the global industry classification standard (...

Using the Johansen cointegration technique, we find empirical evidence of long run comovements between five national stock market indexes and measures of aggregate real activity including the real oil price, real consumption, real money, and real output. Real returns on these indexes are typically related to transitory deviations from the long run relationship and to changes in the macroeconomi...

The present paper analyses the dependence structure between WTI and Brent crude oil spot log-returns using modern copula techniques. In a first step we apply several single equation models to the marginals to account for autocorrelation and volatility clustering. Second, to select both copulas and tail copulas characterising the joint dynamics between the time series we implement and evaluate n...

In the study, we discussed the generalized autoregressive conditional heteroskedasticity model and enhanced it with wavelet transform to evaluate the daily returns for 1/4/2002-30/12/2011 period in Brent oil market. We proposed discrete wavelet transform generalized autoregressive conditional heteroskedasticity model to increase the forecasting performance of the generalized autoregressive cond...

We report an infrared (IR) optical switch using a position-shifting glycerol droplet. The droplet is surrounded by density-matched oil. In the voltage-on state, the droplet shifts in one direction. Upon removing the voltage, the droplet returns to its original position with the aid of interfacial tensions. Due to the strong absorption of glycerol at 1.55 lm, our IR optical switch shows 95:1 con...
