Multivariate analysis of energy commodities during the COVID-19 pandemic: Evidence from a mixed-frequency approach

Andreani, Mila; Candila, Vincenzo; Morelli, Giacomo; … - In: Risks 9 (2021) 8, pp. 1-20

This paper shows the effects of the COVID-19 pandemic on energy markets. We estimate daily volatilities and correlations among energy commodities relying on a mixed-frequency approach that exploits information from the number of weekly deaths related to COVID-19 in the United States. The...
