In most Member countries of the Organisation for Economic Co‐operation Development (OECD), the income gap between rich and poor has widened over the past decades. This article analyses whether and to what extent income taxes and social transfers have contributed to this trend. Has the redistributive impact of different social programmes changed over time? We use microdata from the LIS Cross National Data Center in Luxembourg for the period 1982–2014 and study both the total population and the working‐age population. In contrast to the results of some other studies, especially by the OECD, we do not find that redistribution has declined. Tax‐benefit systems around 2013 are more effective at reducing income inequality compared to the mid‐1980s and the mid‐1990s, especially among the total population. Changes in social programmes are not a driver of greater income inequality across the countries included in this study.

Until recently, social assistance and minimum income benefits have received relatively little attention in the comparative welfare state literature. Relying on two new indicators, this paper examines the development of minimum income benefits across 26 EU and other OECD countries. The real benefit level, the first indicator, is relatively easy to interpret, but international comparisons require adjustments for exchange rates and purchasing power, which can introduce variation that is not related to underlying policy changes. In the second indicator, the net minimum income replacement rate, this disadvantage is cancelled out by construction. Our analysis shows that real benefit levels increased in most countries, whilst replacement rates declined on average. A subsequent qualitative analysis of the changes in the benefit levels confirms that the increased benefit levels reflect policy changes and that the lower replacement rates do not reflect benefit cuts, but relatively larger wage increases. Such a widening gap between benefit levels and wages is in line with the policy agenda of ‘making work pay’. Finally, by analysing the extent to which changes in quantitative indicators reflect actual policy changes, this paper seeks to make a methodological contribution to the ongoing debate on the ‘dependent variable problem’ in the welfare state literature.
