Greg Taylor is an economist whose research focuses on the digital economy, particularly online competition, competition policy, and regulation. His work advances our understanding of digital markets and provides a rigorous foundation for policy and strategic decision making. Recent topics of interest include platform markets, consumer search and online information intermediaries, digital bundling, and the role of data in market competition.
Formally, Taylor’s research spans the domains of industrial organisation, information economics, network economics, game theory, strategy, and marketing. Although his research is primarily theoretical in nature, it deals with some of the most pressing issues of our time, and Dr Taylor has advised government and regulators in the UK and globally.
Besides his research, Dr Taylor is an award-winning teacher of economics. He joined the OII in 2009 after completing a PhD in economics at the University of Southampton.
I am interested in supervising projects from students who have a strong economics background and who plan to apply tools from economic theory and/or game theory to study the digital economy. Special interests include projects related to competition policy, industrial regulation, consumer search and information intermediaries, platform economics, the bundling of digital goods, and the economics of data.
Economics of digital markets, especially competition policy, digital regulation, platform and network economics, information intermediaries, digital bundling, and the economics of data.
