I describe and compare sources of data on citations in economics and the statistics that can be constructed from them. Constructing data sets of the post-publication citation histories of articles published in the "Top 5" journals in the 1970s and the 2000s, I examine distributions and life...

The previously documented trend toward more co- and multi-authored research in economics is partly (perhaps 20 percent) due to different research styles of scholars in different birth cohorts (of different ages). Most of the trend reflects profession-wide changes in research style. Older...

In this essay I review Sylvia Nasar's long awaited new history of economics, Grand Pursuit. I describe how the book is an economic history of the period from 1850-1950, with distinguished economists' stories inserted in appropriate places. Nasar's goal is to show how economists work, but also to...

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...

We revisit the link between poverty, the middle class and institutional outcomes using a newly developed cross-country panel dataset containing detailed information on the distribution of income and expenditures. When the size of the middle class increases (measured as the proportion of people...

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...

This paper presents evidence on the making of the middle class in Africa by exploiting a comparable micro data from the Demographic and Health Surveys (DHS) for thirty-seven countries over two decades consisting of over seven hundred thousand household histories. We constructed a pseudo-panel to...

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...
