The study quantifies the redistributive effect and the total cost of introducing a guaranteed minimum income (GMI) scheme using the Lorenz curve and income distribution parameters (the Gini coefficient, the concentration coefficients, the Kakwani progressivity coefficient). It is assumed that it is too early for behavioural adjustments on the part of GMI beneficiaries and taxpayers. The methodology is applied to empirical data from EU-SILC. Two hypothetical scenarios are created in which all EU Member States introduce a uniform GMI based on the same minimum income threshold: 60% and 70% of the national median household disposable income.
