Abstract
The paper proposes three possible scenarios for future comparative analysis of Covid-related response and discusses how legal transplants, regulatory competition and coordination might explain the regulatory dinamycs in this field. It then argues that growing evidence shows that regulatory action naturally leads to a ‘polity convergence’ driven by ‘biopower’ and ‘biopolitics’. This convergence contradicts initial expectations that the fragmented responses to the emergency could be explained by using the traditional comparative tools, and poses unprecedented critical questions that require broadening the horizons of comparative research.
