Interest in the emergence of a global middle class has resulted in a number of attempts to identify and enumerate who belongs to it . Current research provides wildly different estimates about the size and evolution of the global middle class because of a lack of consensus on appropriate...

In this paper, we analyze how the distribution of selected non-income welfare indicators changed between 1997 and 2003 in Colombia. We use multidimensional propoor growth measurement techniques and create indices for assets, health, education, and subjective welfare using two alternative...

Conventional approaches to the measurement of income-poverty require the ability to identify the poor by reference to a specified poverty line. On the face of it, it may appear to be unproblematic to specify such a poverty line. There are, however, analytical and conceptual difficulties entailed...

When is one distribution (of income, consumption, or some other economic variable) more equal or better than another? This question has proven difficult to answer in situations where distribution functions intersect and no unambiguous ranking can be attained without introducing weaker criteria...

Within the context of the neoclassical growth model I investigate the implications of (initial) endowment inequality when the rich have a higher marginal savings rate than the poor. More unequal societies grow faster in the transition process, and therefore exhibit a higher speed of convergence....

We explore how the underemployment problem of less-developed economies is related to income inequality. Our crucial assumption is that consumers have non-homothetic preferences over differentiated products of formal-sector goods and thus that inequality affects the composition of aggregate...

This paper introduces a theory-based equivalence scale for public in-kind transfers, which justifies comparison of distributions of extended income (cash income plus the value of public services) between European countries. We demonstrate the usefulness of the proposed equivalence scale in an...

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 assess the determinants of the wide variation in the efficiency of foreign aid activities across US-based non-governmental organizations (NGOs). In particular, we analyze whether non-charitable expenditures for administration, management and fundraising depend on the intensity of competition...
