Does risk perpetuate poverty in a credit-constrained economy? Jalan and Ravallion study portfolio and other behavioral responses to measured risk using household panel data for rural China. One-quarter of wealth is held in unproductive liquid forms. But only a small share of this appears to be a...

The authors test how well consumption is insured against income risk in a panel of sampled households in rural China. They estimate the risk insurance models by Generalized Method of Moments, treating income and household size as endogenous. Insurance exists for all wealth groups, although the...

The effect on the poor of changes in the price of staple foods is a central issue in debates on development policy. In the short run the rural rich are likely to gain, and the rural poor to lose, from an increase in the relative price of food staples in a food producing economy. However, in the...

Theoretical work has shown that nonlinear dynamics in household incomes can yield poverty traps and distribution-dependent growth. If this is true, the potential implications for policy are dramatic: effective social protection from transient poverty would be an investment with lasting benefits,...

This article is a commentary on a new book"Hunger and Public Action,"by authors Jean Dreze and Amartya Sen. The article compares the book's conceptual approach and policy recommendations to those of other recent writings on poverty and hunger. Researchers trying to understand the causes of a...

It is widely assumed that pervasive credit market failures mean that a person's current wealth is critical to whether or not that person can take up opportunities to start a new business. The authors show that inequality in wealth can be either good or bad for the level of entrepreneurship in an...

In theory, it is possible that the persistent poverty that has emerged in many transition economies, is attributable to underlying, non-convexities in the dynamics of household incomes - such that a vulnerable household will never recover from a sufficiently large, but short-lived shock to its...

The widely held view that larger families tend to be poorer in developing countries has influenced research and policies. But the basis for this"stylized fact"is questionable, the authors argue. Widely cited evidence of a strong negative correlation between size and consumption per person is...

This paper discusses the effect that changes in individual incomes have on aggregate undernutrition. Undernutrition depends not only on nutrient intakes but on other factors, including nutrient requirements - which may differ widely amongst people. The author offers an approach to measuring the...

The authors use China's national household surveys for rural and urban areas to measure and explain the welfare impacts of the changes in goods and factor prices attributed to WTO accession. Price changes are estimated separately using a general equilibrium model to capture both direct and...
