We examine the phenomenon of real-income stagnation in a large cross-section of countries during the last four decades. Stagnation is defined as negligible or negative growth extending over a number of years. We find that stagnation has affected more than three fifths of countries (103 out of...

Recent influential studies among development economists claim that aid to developing countries is not nearly as beneficial to recipient nations as had been expected. Are these statistical analyses right? One problem is that total aid, on which most studies are based, includes two distinct kinds...

This paper investigates how estimates of the extent and trend of income poverty in China between 1990 and 2001 vary as a result of alternative plausible assumptions concerning key parameters that influence the poverty line and estimated consumption levels. Our methodology focuses on the...

This paper examines the phenomenon of real-income stagnation (in which real-income growth is negligible or negative for a sizable uninterrupted sequence of years). It analyzes data for four decades from a large cross-section of countries. Real income stagnation is a conceptually distinct...

We evaluate the claim that world consumption poverty has fallen during the 1990s in light of alternative assumptions about the extent of initial poverty and the rate of subsequent poverty reduction in China, India, and the rest of the developing world. We assess the extent of poverty using two...

This paper examines the phenomenon of real-income stagnation (in which real-income growth is uninterruptedly negligible or negative for a sizable sequence of years). We analyse data for four decades from a large cross-section of countries. Real income stagnation is a conceptually distinct...

We analyze the growth impact of official development assistance to developing countries. Our approach is different from that of previous studies in two major ways. First, we disentangle the effects of two kinds of aid: developmental and non-developmental. Second, our specifications allow for the...

We review the recent empirical literature on global poverty, focusing on key methodological aspects. These include the choice of welfare indicator, poverty line and purchasing power parity exchange rates, equivalence scales, data sources, and estimation methods. We also discuss the importance of...
