Leading world economies are moving towards a sustainable future putting high pressure on the oil and gas industry. Additionally, COVID-19 has created an unseen turmoil in energy markets, where all players have to deal with high uncertainty. My research helps uncover how oil and gasoline supply and demand respond to changes in energy markets. I also shed light on the impact of gasoline prices, uncertainty, and consumers' information-seeking behavior on vehicle purchase decisions. My goal is to use applied econometric techniques using macro and micro level data to contribute to the transition to a more sustainable future.
