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.
