| Gaia: | The hypothesis that institutions directly influence income distribution has been defended by numerous authors. However, it may be observed that institutions are deteriorating in developed economies, which poses the question: could a phenomenon similar to the Kuznets curve be applied? Using the Worldwide Governance Indicators’ index of the quality of institutions from the World Bank, and data on per capita GDP from the Maddison project (using a sample of 156 countries in the period of 1996–2015), there appears to be empirical evidence in favour of the existence of an institutional Kuznets curve, using the Prais-Winsten estimation and the Generalised Method of Moments (GMM).
