Are the determinants of chronic and transient poverty different? Do policies that reduce transient poverty also reduce chronic poverty? The authors decompose measures of household poverty into chronic and transient components and use censored conditional quantile estimators to investigate the...

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...

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,...

The authors use propensity-score matching methods to estimate the income gains to families of workers participating in an Argentinian work-fare program. The methods they propose are feasible for evaluating safety net interventions in settings in which many other methods are not feasible. The...

The effects of public investments aimed at directly improving children's health are theoretically ambiguous, since the outcomes also depend on indirect effects through parental inputs. The authors investigate the role of such inputs in influencing the incidence of child health gains from access...

Can place of residence make the difference between growth and contraction in living standards for otherwise identical households? The authors test for the existence of spatial poverty traps, using a micro model of consumption growth incorporating geographic externalities, whereby neighborhood...

The authors study transient poverty in a six-year panel dataset for a sample of 5,000 households in post-reform rural China. Half of the mean squared poverty gap is transient, in that it is directly attributable to fluctuations in consumption over time. There is enough transient poverty to...

Poor-area development programs- in which the government transfers extra resources to unusually poor areas -have been widely used to fight poverty. There has been some research on such programs, but little is known about their impact on household living standards over time. The authors address...

July 1999 - A workfare program was introduced in response to high unemployment in Argentina. An ex-post evaluation using matching methods indicates that the program generated sizable net income gains to generally poor participants. Jalan and Ravallion use propensity-score matching methods to...
