The World Inequality Lab aims to promote research on global inequality dynamics. Its core mission is to maintain and expand the World Inequality Database. It also produces inequality reports and working papers addressing substantive and methodological issues. The Lab regroups about twenty research fellows, research assistants and project officers based at the Paris School of Economics. It is supervised by the same executive committee as WID.world, composed of 5 co-directors. The World Inequality Lab works in close coordination with the large international network (over one hundred researchers covering nearly seventy countries) contributing to the database. In addition to the year-round updates to the database and working papers, the World Inequality Lab publishes the World Inequality Report every two years. The objective is to highlight new findings and research analysis emanating from the database, and to draw implications for the global inequality debate. The World Inequality Report aims to become the reference global report on inequality and to attract extensive coverage in the international media. The first edition - the World Inequality Report 2018 - was released in december 2017.
