The COVID-19 pandemic has intensified ongoing debates about the future of capitalism and the economic framework best suited to meet the post-pandemic world’s long-term needs. Developed economies will, of course, need strong growth to offset the economic damage wrought by the virus, and to rise to the challenges posed by climate change and societal aging. And yet, across the developed world, the pace of economic growth has been slowing for decades, casting doubt on how these challenges will be met.
How should the gap between actual and necessary growth be closed? Should developed economies continue to focus on Keynesian demand management, thus risking the accumulation of ever more debt? Or should we shift to a longer-term, rules-based approach that anchors expectations and builds confidence, albeit at the expense of some policy discretion?
