It has been suggested that income adequacy is an important condition for a fair work-test to apply. This article provides new evidence about the construction of just social minimums by analysing the relationship between social assistance, benefit adequacy, and labour market activation. Does social assistance provide benefits at levels necessary to escape poverty? To what extent is the development of benefit adequacy related to active labour market policy? The empirical analyses combine macro-level institutional data from the SaMip data set and micro-level income data for 28 European welfare systems in 1990–2008. It is shown that social assistance seldom reaches commonly applied poverty thresholds. The adequacy of social assistance has also declined, along with the increased emphasis on the activation of beneficiaries. It therefore appears difficult to perceive European social assistance programmes as just distributive instruments.
