Voter perceptions and the politics of hidden costs in unilateral sustainable supply chain regulations
2025-10-01
While political opposition to economic globalisation has increased, several governments have adopted stricter unilateral interventions in global supply chains in the name of sustainability, despite their potentially significant economic costs. We argue that these policy choices are partly driven by politicians’ incentives to align with domestic public opinion. In particular, new information disclosure rules enable governments to implement market access restrictions compliant with binding trade liberalisation commitments while (a priori) obscuring their costs to voters. We assess the latter argument with original survey data and experiments with representative samples from the twelve major OECD importing economies ( N = 24,000). Indeed, citizens expect substantive benefits while discounting costs from these new regulations, resulting in majority support for rather stringent standards. We further observe that these relationships are muted in countries with high trade exposure. These findings suggest that governments may strategically implement unilateral policies with high-cost obfuscation to garner domestic voter support, driving regulatory proliferation in international economic relations.
