We analyze the impact of vaccine news announcements by leading vaccine companies on the financial and commodity markets from January to December 2020. We show that the vaccine announcements moved stock prices of the leading vaccine companies, stock markets in the U.S. and Europe (but not in Asia...

Oil and gas company returns are compared between upstream, midstream, and down-stream sectors from 2000 through 2020. Crude oil, natural gas, and distillate returns reflect project risk, infrastructure, and conditions within the industry. Equity, commodity, and distillate markets positively...

This paper explores the asymmetric connectedness of systemic risk between the oil and global stock markets in both the time and frequency domains. To do so, we introduce time-varying parametric vector autoregressive (TVP-VAR) spillover index models and implied volatility indices to examine risk...

What is the role of financial speculation in determining the real oil price? We find that while macroeconomic shocks have been the major upward driver of the real oil price since the mid 1980s, also financial shocks have sizably contributed since the early 2000s, and at a much larger extent...

We analyze the relation between volatility and speculative activities in the crude oil futures market and provide short-term forecasts accordingly. By incorporating trading volume and opening interest (speculative ratio) into the volatility dynamics, we document the subtle interaction between...

The dramatic reduction in global demand, and the decline in the spot price of crude oil in the second half of last year, may have significant implications for the future supply of oil. Investments in conventional methods of extraction have been constrained, since easily accessible oil reserves...

We examine the implications of increased unconventional crude oil production in North America. This production increase has been made possible by the existence of alternative oil-recovery technologies and persistently elevated oil prices that make these technologies commercially viable. We first...

As in many African countries, crude oil importation is a major drain on the economy of Ghana. We estimate short-run and long-run import demand models for crude oil using data over the period 1980-2012. Results show that demand for crude oil is price inelastic in the short-run but elastic in the...
