In a polarised and highly unequal country such as South Africa, it is unlikely that a definition of the middle class that is based on an income threshold will adequately capture the political and social meanings of being middle class. We therefore propose a multi-dimensional definition, rooted...

Defining the 'global middle class' as being neither poor nor rich in the developed world, we estimate the size of the global middle class in China and 33 other countries and analyze China's expanding middle class in international perspective. China's global middle class has grown rapidly and has...

The world is changing its socio-economic landscape. By doing so, the phenomenon of a growing middle-class appears. Both household surveys and growth projections suggest that only about one-third of the global middle class is based in Asia. However, between 2009 and 2017, the global middle-class...

Empirical evidence for the U.S. suggests that illicit consumption of opioids increases in association with socio-economic deprivation of the middle-class. To explore the underlying mechanisms, we set up a task-based labor market model with endogenous mental health status and a health care...

In many developing countries, the supply of skilled workers is likely to continue to be stronger than demand, and this should drive down the skill premium and reduce inequality. Within the limitations of any exercise based on simulations, this paper finds that the recently observed reduction in...

We investigate whether Chinese household incomes have caught up to those of the middle class in the developed world. Using nationwide survey data for 2002 and 2013, we find considerable catch up. Defining the global middle class as being neither poor nor rich in the developed world, we estimate...

Income inequality is on the rise, and everyone, from President Obama and Pope Francis to Prince Charles and Standard & Poor's, is talking about it. But these conversations about what are arguably the most significant changes in the distribution of incomes and earnings since the 1940s are leading...

Middle class values have long been perceived as drivers of social cohesion and growth. In this paper we investigate the relation between class (measured by the position in the income distribution), values, and political orientations using comparable values surveys for six Latin American...
