Nancy Birdsall at the Center for Global Development has an interesting new paper The (Indispensable) Middle Class in Developing Countries; or, the Rich and the Rest, Not the Poor and the Rest.
ABSTRACT: Inclusive growth is widely embraced as the central economic goal for developing countries, but the concept is not well defined in the development economics literature. Since the early 1990s, the focus has been primarily on pro-poor growth, with the “poor” being people living on less than $1 day, or in some regions $2 day. The idea of pro-poor growth emerged in the early 1990s as a counterpoint to a concern with growth alone (measured in per-capita income) and is generally defined as growth which benefits the poor as much or more than the rest of the population. Examples include conditional cash transfers, which target the poor while minimizing the fiscal burden on the public sector, and donors’ emphasizing primary over higher education as an assured way to benefit the poor while investing in long-term growth through increases in human capital. Yet these pro-poor, inclusive policies are not necessarily without tradeoffs in fostering long-run growth. In this paper I argue that the concept of inclusive growth should go beyond the traditional emphasis on the poor (and the rest) and take into account changes in the size and economic command of the group conventionally defined as neither poor nor rich, i.e., the middle class.
