During the Covid-19 crisis, governments have taken a range of fiscal and economic measures such as subsidies, transfers, tax deferrals, tax cuts and cash payments. These measures have challenged the economic sustainability in multilevel governance systems, namely the trade-off between current and future consumption. WP6 collects a dataset on economic and fiscal measures at the subnational and national in 31 European countries and at the EU and international level. It then explores the impact of multilevel governance and other explanatory factors of the political legitimacy of these measures relying on different quantitative methods. Based on the results of these analyses, WP6 provides recommendations on how to foster economic sustainability in crisis
governance and its legitimacy.
