The 20th Human Development Report has introduced a new version of its famous Human Development Index (HDI). The HDI aggregates country-level attainments in life expectancy, schooling and income per capita. Each year's rankings by the HDI are keenly watched in both rich and poor countries. The...

Empirical studies of tax and benefit incidence routinely ignore behavioral responses and measurement errors. This paper offers an econometric method of estimating the mean benefit withdrawal rate (marginal tax rate) allowing for incentive effects, measurement errors, and correlated latent...

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...

It seems natural to expect the rich to oppose policies to redistribute income from the rich to the poor, and the poor to favor such policies. But this may be too simple a model, say the Authors. Expectations of future welfare may come into play. Well-off people on a downward trajectory may well...

The authors argue that the welfare inferences drawn from subjective answers to questions on qualitative surveys are clouded by concerns about the structure of measurement errors and how latent psychological factors influence observed respondent characteristics. They propose a panel data model to...

Cross-country comparisons of social indicators controlling for income and/or social spending have been widely used to measure and explain"social efficiency"analogously to"technical efficiency"in production. The author argues that these methods are clouded in ambiguities about what exactly is...

The author tests for external effects of local economic activity on consumption and income growth at the farm-household level using panel data from four provinces of post-reform rural China. The tests allow for non-stationary fixed effects in the consumption growth process. Evidence is found of...

Two tradeoffs have been widely seen to severely constrain the scope for attacking poverty using redistributive transfers in poor countries: an equity-efficiency tradeoff and an insurance-efficiency tradeoff. The author provides a critical overview of recent theoretical and empirical work that...
