We study the possibility of completing data bases of a sample of governance, diversification and value creation variables by providing a well adapted method to reconstruct the missing parts in order to obtain a complete sample to be applied for testing the ownership-structure/diversification...

In the present paper, a fuzzy logic based method is combined with wavelet decomposition to develop a step-by-step dynamic hybrid model for the estimation of financial time series. Empirical tests on fuzzy regression, wavelet decomposition as well as the new hybrid model are conducted on the well...

This paper examines the empirical causal relationship between energy consumption, CO2 emissions and economic growth for six oil-exporting countries from the Golf Cooperation Council (GCC) region over the period 2000:2011. Bootstrap panel Granger causality test approach is used which take account...

This paper examines the multi-scale relationship between the interest rate, exchange rate and stock price using wavelet transform. In particular, we apply the maximum overlap discrete wavelet transform (MODWT) to the interest rate, exchange rate and stock price for US over the period 1990:1-...
