Changes in pension systems (in the past) will affect the present income situation of retired people, for instance, which can obscure findings and blur the picture. The analyses in this study focus on the working-age population, which allows the report to paint a more precise picture of the processes at work in the labour market and how they shape the incomes of households.6 The analytical framework of the report is outlined in Box 1. Part I looks at whether and how trends in globalisation, technological change and institutions and policies translated into inequalities in wages and earnings.
