Extant literature establishes co-movements among commodity (metal and oil) prices; whereas oil price/shocks aggregate, as a lone predictor, has relative predictability for most financial assets. We assess the predictability of Baumeister and Hamilton's (2019) decomposed oil shocks (economic...

Interpersonal violence poses a formidable obstacle to harmonious coexistence, socioeconomic development, and public health globally, given its deleterious consequences and attendant mortality. In a multicultural society like Nigeria, violence is an unfortunate inevitability. This study...

We checked against the law of one price between urban and rural consumer price indices of goods and services in Nigeria, using data that span January 1995 to April 2024. By first testing for persistence in price indices, we found a similar pattern of persistence that is non-mean reverting in all...

Day-of-the-week persistence and seasonality of electricity prices in Spain, spanning 01/01/2006 to 04/11/2021, are investigated by employing updated fractional persistence frameworks in nonlinear settings. The results show marginal higher persistence in electricity prices during the working days...

Day-of-the-week persistence and seasonality of electricity prices in Spain, spanning 01/01/2006 to 04/11/2021, are investigated by employing updated fractional persistence frameworks in non-linear settings. The results show marginal higher persistence in electricity prices during the working...

This study uses the recently developed Generalized Autoregressive Conditional Heteroscedasticity (GARCH) model-based unit root test of Narayan et al. (2016) to examine the stock market efficiency of 19 Asian countries, using daily prices. The model flexibly accounts for heteroskedasticity and...

This paper deals with the analysis of long-run relationships of fear indices for US stocks, commodities, and the energy sector with global fear indices for stocks and oil. Departing from the classical literature, fractional integration, and cointegration techniques are used to determine the...

The study investigates the impact of uncertainties on energy pricing during the COVID-19 pandemic using five uncertainty measures that include the COVID-Induced Uncertainty (CIU), Economic Policy Uncertainty (EPU), Global Fear Index (GFI); Volatility Index (VIX), and the Misinformation Index of...

We develop an index of uncertainty, the COVID-19 induced uncertainty (CIU) index, and employ it to empirically examine the vulnerability of energy prices amidst the COVID-19 pandemic using a distributed lag model that jointly accounts for conditional heteroscedasticity, autocorrelation,...
