Tommaso Crescioli is a postdoctoral fellow at Bocconi's Department of Economics and IGIER and a final-year Ph.D. candidate in political economy at the London School of Economics and Political Science. His research encompasses two main streams. The first examines how economic openness and institutions impact the strategies and objectives of international organizations, governments, and large firms. It investigates how the interactions between these actors shape competition policy and the evolution of market power. The second stream tries to establish a novel research agenda by looking at the political implications of rising market power via channels different from lobbying and rent-seeking. It does so by looking at how the increasing dominance of powerful firms influences citizens' political behavior and how politicians adjust their strategies consequently.
