About the Institute

The Government Transparency Institute (GTI) is a non-partisan think tank researching and advocating good governance. GTI was born from the research and civil society activism of its founder Mihály Fazekas at the University of Cambridge in 2015. GTI aims to provide an independent, research-driven voice to the causes of transparency, anti-corruption, and good governance in Europe as well as globally. GTI conducts innovative research on the causes, characteristics, and consequences of low-quality governance with interdisciplinary analysis, drawing on political science, economics, law, and data science. It is financed by private donations, research grants, and government contract work, and works independently of political parties or special interest groups.

GTI helps citizens and companies hold their governments accountable through the publication of novel datasets and robust analyses. GTI’s unique approach uses Big Data, econometrics, and qualitative methods to understand micro-behaviour, macro-outcomes, and the links between the two. Its main themes include corruption, collusion, spending efficiency, administrative quality, public procurement, and regulatory quality. We believe that the combination of a thorough qualitative understanding and precise quantitative measurement of the state is the foundation of good governance.


Mihály Fazekas, scientific director & founder  


Mihály Fazekas is the scientific director of GTI, while also serving as an associate professor at the Central European University, Department of Public Policy, with a focus on using Big Data methods to understand the quality of government globally. He has a PhD from the University of Cambridge where he pioneered Big Data methods to measure and understand high-level corruption in Central- and Eastern Europe.

His research and policy interests revolve around corruption, favouritism, private sector collusion, and government spending efficiency. Methodologically, he has experience in both quantitative and qualitative methods in diverse fields such as public policy, economics, and political science. He worked at the University of Cambridge as the scientific coordinator of the Horizon 2020 funded project DIGIWHIST which used a Big Data approach to measuring corruption risks, administrative capacity, and transparency in public procurement in 33 European countries. While at University College London, he served as a co-Principal Investigator on the Global Integrity/FCDO funded research project looking at anti-corruption in development aid-funded as well as national procurement. He regularly consults the European Commission, Council of Europe, EBRD, OECD, World Bank, and a range of national governments and NGOs across the globe. He led a team of FCDO UK, GTI, and IMF which won the 1st prize at the IMF Anti-Corruption Challenge for measuring corruption and its costs globally.
