2023 Income and wealth inequality: drivers and consequences Conference

Income and wealth inequality: drivers and consequences

September 27-29, 2023


The conference aims to introduce the scientific community to the latest scientific inquiries on inequality in the context of cross-country comparative research to better understand the of nature of income and wealth inequality by asking two fundamental questions: “What drives inequality?” and “What are the consequences of economic and social inequality?”

Since economic inequality is a complex problem, this conference brings together scholars representing various social science disciplines that deal with broadly defined research topics, to name a few, inequality trends, intergenerational inequality, and gender inequality in combination with the institutional and socio-demographic context, such as labor market, pensions, education, or inheritances. During this conference, we will also discuss the impact of the crisis on inequality and assess social and fiscal policies.

The organizing and scientific committees invited scholars to present the latest research developments on income and wealth inequality from a theoretical, historical, and comparative perspective, elaborate on the role of public policy, progress in the evolution of inequalities, and understand the economic and social consequences of increasing inequalities.

The conference brings together young and experienced scholars from four continents: North and South America, Asia, and Europe. The conference begins with a workshop for young researchers on software and techniques for inequality measurements and analysis that introduces machine learning for analyzing economic inequalities. Additionally, representatives from academia meet with policymakers during the panel titled “The Bridge between Research and Economic Policy.” The conference will have an inaugural speech and four keynote lectures from prominent scholars representing various streams of inequality and poverty research.

The Best Paper Award and the Best Poster Award were given in recognition of outstanding research presented at the conference. The Best Paper Award went to Benjamin Tippet (University of Greenwich) for his work “Finding Fortunes: A New Methodology to Estimate Missing Wealth in Survey Data.” The Best Poster Award was received by a doctoral student from the University of Warsaw, Ivan Skliarov, for his scientific work titled “Does Reckless Risk or Careful Planning Make Households Wealthy? A study of the US based on the Luxembourg Wealth Study database.”
