Dr Andres Mejia Acosta is a political scientist whose current research looks at how the political management of natural resource revenues affects development goals. His work "Informal Coalitions and Policymaking in Latin America" (New York: Routledge, 2009) looks at how formal and informal political institutions produce policy reforms in Latin America and the Caribbean.

Publications include articles and book chapters on electoral systems, political parties, legislative politics, budget politics, the policymaking process, informal institutions, and democratic governance. Besides this he has been involved in a wider comparative study ‘Analysing Nutrition Governance’, funded by UKAid, which looks at nutrition rates and government nutrition programmes in Bangladesh, Brazil, Ethiopia, India, and Zambia. He has done consulting work for Club de Madrid, The Carter Center, Eurasia Group, Freedom House, United Nations Development Programme, the Inter American Development Bank and the International Institute for Democracy and Electoral Assistance.

Andrés has been Co-Convenor of the Research Programme on Revenue Collection and State Capacity for the Centre for the Future State. He is currently working on a book manuscript on the political management of natural resource revenues in the Andean region.
