Using newly comprehensive data and tools from the Global Consumption and Income Project or CGIP, covering most of the world and five decades, we present a portrait of the changing global distribution of consumption and income and discuss its implications for our understanding of inequality,...

We show that measures of inequality of opportunity (IOP) fully consistent with Roemer (1998)’s IOP theory can be straightforwardly estimated by adopting a machine learning approach, and apply our novel method to analyse the development of IOP in Germany during the last three decades. Hereby,...

A transfer from a richer individual to a poorer one seems to be the most intuitive and straightforward way of reducing income inequality in a society. However, can such a transfer reduce the welfare of the society? We show that a rich-to-poor transfer can induce a response in the individuals'...

"Shared prosperity" has become a common phrase in the development policy discourse. This short paper provides its most widely used operational definition - the growth rate in the average income of the poorest 40 percent of a country's population - and describes its origins. The paper discusses...

To study how information about educational inequality affects public concerns and policy preferences, we devise survey experiments in representative samples of the German population. Providing information about the extent of educational inequality strongly increases concerns about educational...

It is well known that income and health are positively associated. Much less is known about the strength of this association in times of growth and recession. We develop a novel decomposition method that focuses on isolating the roles played by government transfers versus market transfers on...

Using data from the China Health and Nutrition Survey (CHNS), this study analyses changes in bodyweight (BMI and waist circumference) distributions between 1991 and 2011 among adults aged 20+ in China. To do so, we quantify the source and extent of temporal changes in bodyweight and then...

Our hypothesis is that Nigeria is going through a process of economic polarization. An analysis of this type is new for Nigeria; the limited availability of comparable data has hindered an investigation that requires data series not too close in time. The present paper tries to overcome this...
