Understanding economic inequalities across a wide range of high-income countries, each with their own institutions and policies, can provide insights that focussing on only one country cannot. Some countries may look particularly unequal in one dimension, but not in others, leading us to think carefully about the measurement of inequalities. A careful comparison of the experience of many countries can substantially broaden the scope for learning about the role of different potential policies and of social and demographic factors.
The aim of the Country Studies project – a parallel project to the IFS Deaton Review – is to examine a broad set of inequalities in a coherent framework across the major economies of Europe and North America and how they have changed in recent decades, including through the COVID-19 pandemic. Led by Richard Blundell, Jonathan Cribb, and James Ziliak, we aim for this to provide a major source of comparative international research on economic inequality.
Each country has written a comprehensive report into the evolution of labour market and income inequalities, and their interactions with education and gender in particular. We examine how social changes – such as the labour market position of women, higher levels of formal education, rising levels of immigration – have affected different countries and different forms of inequalities. And how the changes to the tax and benefit system have acted to dampen, or increase, household income inequalities. These reports were launched in November 2023.
In June 2024, a special issue of the journal Fiscal Studies was published which contained short papers setting out and explaining key patterns on working-age inequalities in English-speaking and Nordic countries using the data harmonised as part of this project. The introductory paper to the special issue also provides an description of the project as a whole and summarises the individual papers. The special issue also contains a paper which draws together evidence on gender gaps in the labour market using data from all 17 countries.
In September 2024, the second part of the special issue of Fiscal Studies was published. This contains short papers on the remaining countries in the project, from Western and Southern Europe. A introductory paper summarises the contributions of the papers in this volume. The volume also includes a paper that draws together international evidence on education and inequality.
