Vicente Silva Didier

Vicente works at the intersection of research and tax policy advocacy, with over a decade of experience advancing tax justice and strengthening democratic governance. He currently serves as a Senior Policy Advisor at the International Tax Observatory, where he advances evidence-based tax policy solutions and support international tax cooperation. He also helps to promote the Observatory’s work with policymakers, media, and key stakeholders.

Previously, Vicente led the Economic Justice Programme at the Global Initiative for Economic, Social and Cultural Rights (GI-ESCR), where he helped shape international advocacy strategies and positioned the organisation in key negotiations on global tax reform, fiscal governance, and climate finance. Before joining GI-ESCR, he worked at TECHO, one of Latin America’s leading NGOs addressing poverty and inequality, where he coordinated multi-stakeholder efforts to advance structural reforms in housing rights and urban governance.

Throughout his career, Vicente has engaged across major multilateral forums -including the UN, COP, IMF, and G20- to influence fiscal policy debates, develop policy proposals, and build civil society coordination. His work has focused particularly on strengthening Global South leadership in international tax debates and fostering collaboration among governments, parliamentarians, and civil society actors. His academic research examines the political dynamics of tax reform, with a particular focus on how fiscal policy can help rebalance power and reinforce democratic institutions in high-inequality contexts. His recent publications include contributions to Human Rights and Economic Inequalities (Cambridge, 2020) and Social Rights and the Constitutional Moment (Hart, 2022).

Vicente holds an LLM in International Law and Human Rights from the University of Essex and an MSc in Inequalities and Social Science from the London School of Economics and Political Science.
