Rethinking international subsidy rules

Geo-economic tensions, notably associated with the rise of China, and global collective action problems—climate change and the COVID-19pandemic—call for international cooperation to revise and develop rules to guide both the use of domestic subsidies and responses by governments to cross-border competition spillover effects. Current WTO rules dividing all subsidies into prohibited or actionable categories are no longer fit for purpose. Piecemeal efforts in preferential trade agreements and bi- or trilateral configurations offer a basis on which to build but are too narrow in scope. Addressing spillover effects of subsidies could start with G20 countries launching a work programme to mobilise an epistemic community concerned with subsidy policies, tasked with building a more solid evidence base on the magnitude, purpose and effects of subsidy policies. The need for such cooperation has become even more pressing by the COVID-19 pandemic and associated increase in the use of subsidy programmes in major economies.
