Our research explores how the COVID-19 pandemic has influenced asymmetric spillover effects in oil and gold markets. Through a VAR(p)-BEKK-AGARCH(1,1) model fitted to daily price data, 1) we find evidence of only from market that this effect is stronger during 2) conclude negative information shock larger impact on return volatility compared positive intensified pandemic.

ABSTRACT An experimental study has been conducted to visualise the instantaneous streamwise and spanwise flow patterns of a normal shock wave impinging over a rounded contour bump in a Mach 1.3 free-stream. A quartz-made transparent shock generator was used, so that instantaneous images could be captured during the oil-flow visualisation experiments. Fluorescent oil with three different colours...

a r t i c l e i n f o A global computable general equilibrium model is used to analyze the economic impacts of rising oil prices with endogenously determined availability of biofuels to mitigate those impacts. The negative effects on the global economy are comparable to those found in other studies, but the impacts are unevenly distributed across countries/regions or sectors. The agricultural s...

This paper uses a ßexible approach to characterize the nonlinear relation between oil price changes and GDP growth. The paper reports clear evidence of nonlinearity, consistent with earlier claims in the literature— oil price increases are much more important than oil price decreases, and increases have signiÞcantly less predictive content if they simply correct earlier decreases. An alternativ...

This paper considers an application of the Markov switching vector error correction model to analysis long-run and short-run dependence Russian real GDP exchange on oil prices. An algorithm for estimation with a priori information state hidden chain in some periods time is provided. It shown that period 1999–2018 two different regimes are well defined: slow adjustment rate sharp reaction respon...

Article history: Received 20 June 2014 Received in revised form 25 September 2014 Accepted 26 September 2014 Available online 5 October 2014 This paper investigates the time-varying impact of oil price uncertainty on stock prices in China using weekly data on ten sectoral indices over the period January 1997–February 2014. The estimation of a bivariate VAR-GARCH-in-mean model suggests that oil ...

For decades, humans have been consuming large quantities of oil, coal and natural gas. Consequently, people must now take responsibility for having participated in productive activities that have caused the emissions of greenhouse gas (GHG) which has damaged the environment and caused problems associated with abnormal weather. Previous studies investigated the relationships between energy and c...

Industries are rarely perfectly competitive. They also rarely comprise only firms who transact solely with consumers. Rather, in many industries—including health care, technology, media, and finance—firms are oligopolistic and negotiate terms of trade with one another across different market segments. Understanding how firms compete and interact in these vertical markets is critical not only fo...
