The lecture series aimed to bring together the research and working communities at large in Luxembourg around a theme which researchers have traditionally associated with this country: income studies, widely interpreted. The Luxembourg Income Study, the cross-sectional database of micro-economic income data for social science research, is known world-wide and was founded in Luxembourg in 1983. The unifying thread of the lectures is Inequality, that is, differences in the distribution of some attributes, such as income and wealth, among the population. Each lecture tackled the links between these differences and a central social phenomenon. The speakers were among the best-known experts worldwide and were gifted with great communication skills. Each lecture was a source of inspiration for an audience with different levels of expertise, ranging from a BA in social sciences to expert researchers in the specific topic.Prof. D’Ambrosio is the promoter of this initiative and has contacted all potential local stakeholders, which are the co-organizers of the lectures. Her aim was to be as inclusive as possible in order to stimulate discussion, build a pan-Luxembourgish community and further research on the theme of the PEARL research programme of which she is a member. The topics as well as the speakers were jointly proposed by all of the organizers being part of the Scientific Committee.It was decided to host the lectures at the premises of the European Investment Bank, at the heart of the country, following our relocation in Belval. Prof. D’Ambrosio was the main contact with the speakers and among the organizers.
