Abstract:
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). The authors analyze data for four decades from a large cross-section of countries. Real income stagnation is a conceptually distinct phenomenon from low average growth and other features of the growth sequence that have been previously considered. The authors find that real income stagnation has affected a significant number of countries (103 out of 168), and resulted in substantial income loss. Countries that suffered spells of real income stagnation were more likely to be poor, in Latin America or sub-Saharan Africa, conflict ridden and dependent on primary commodity exports. Stagnation is also very likely to persist over time. Countries that were afflicted with stagnation in the 1960s had a likelihood of seventy-five percent of also being afflicted with stagnation in the 1990s.

2. Chinese Poverty: Assessing the Impact of Alternative Assumptions

Abstract:
This paper investigates how estimates of the extent and trend of consumption poverty in China between 1990 and 2001 vary as a result of alternative plausible assumptions concerning the poverty line and estimated levels of consumption. The exercise is motivated by the existence of considerable uncertainty about the appropriate poverty lines to apply and the level and distribution of resources in China. The methodology of this paper focuses on the following sources of variation: alternative purchasing power parity conversion factors (used to convert an international poverty line), alternative estimates of the level and distribution of private incomes, alternative estimates of the propensity to consume of lower income groups, and alternative consumer price indices. It is widely believed that substantial poverty reduction has taken place in China in the 1990s, and we find this conclusion to be robust to the choice of assumptions. However, estimates of the extent of Chinese poverty in any year are greatly influenced by the assumptions made. China's record of reducing consumption poverty is dramatic. It is unclear whether this achievement has been comparable across regions and whether there have been corresponding national improvements in other aspects of human well-being.

3. Why do some countries produce so much more output per worker than others?

Abstract:
To explain differences in output per worker across countries, we test for the workings of a learning-by-doing hypothesis and the hypo thesis that the effectiveness of human capital depends on the laws and institutions that promote workplace practices that allow skills to develop. The quality of laws and institutions in the workplace is measured by an index of economic security (ESI). We find that ESI is a good proxy for human capital whilst educational attainment is not. We also find that countries with high ESI use more effectively the skills of the workforce and are better at exploiting profitable opportunities in capital markets.
